“That’s a vagina,’’ quipped Charles ‘Pete’ Conrad Jr. “Definitely a vagina.’’ The psychiatrist noted his response without a word, perhaps realising, perhaps not, that he was the victim of yet another wisecrack from the gap-toothed, balding Navy lieutenant. Yet, despite his comments about each of the Rorschach cards shown to him, Conrad was not entirely obsessive about the female genitalia. He had actually been tipped-off the night before by another astronaut candidate, Al Shepard: what the NASA psychiatrists were really looking for was male virility. ‘‘I got the dope on the psych test,’’ Shepard had assured him. ‘‘No matter what it looks like, make sure you see something sexual.’’ So Conrad did.

His key concern, though, that spring in 1959, had been the impact that this crazy ‘Project Mercury’ idea might have on his career. Instead of logging hours in the Navy’s new F-4 Phantom fighter, he spent a week at the Lovelace Clinic in Albuquerque, New Mexico, much of his time focused on the provision of stool,

semen and blood samples and the collection of 24-hour bagfuls of urine. On the evening before a major stomach X-ray, told not to drink alcohol after midnight, Conrad had sat up until 11:57 pm draining a bottle with Shepard and another naval aviator called Wally Schirra to loosen themselves up for the next day. Conrad doubted that Lovelace’s invasive tests had anything remotely to do with spaceflight: the physicians, he told Shepard, seemed far more interested in “what’s up our ass’’ than in their flying abilities. Shepard had warned him to be careful – to give the right answers to questions and to remember that Lovelace’s staff were watching their every move.

In spite of his frustration, Conrad persevered. He followed Shepard’s advice, saw the female anatomy in every Rorschach card, deadpanned to a psychologist that one blank card was upside down, pedalled a stationary bicycle for hours, sat in a hot room for an age, then dunked his feet into ice-cold water and argued with one of the physicians that he considered it pointless to have electricity zapped into his hand through a needle. However, all this torture, Conrad felt, would at least give him the opportunity to lay his entire naval career on the line for just one chance to fly something even faster: to ride a rocket, outside Earth’s atmosphere, “at a hell of a lot more Machs than anything he was flying right now’’. Flying higher and faster, and pushing his own boundaries, had been the story of Conrad’s life.

Born in Philadelphia, Pennsylvania, on 2 June 1930, the offspring of a wealthy family which made its fortune in real estate and investment banking, Conrad’s father insisted that he be named ‘Charles Jr’ – “no middle name’’ – although his strong – willed mother, Frances, felt that this tradition of Charleses should be broken. Frances liked the name ‘Peter’, wrote Nancy Conrad in her 2005 biography of her late husband, and although it never became his official middle name, Charles Conrad Jr would become known as ‘Peter’ or ‘Pete’ for the rest of his life. His fascination with anything mechanical reared its head at the age of four, when he found the ignition key to his father’s Chrysler and reversed it off the drive. Later, in his teens, he worked summers at Paoli Airfield, mowing lawns, sweeping and doing odd jobs for free flights. Aged 16, he even repaired a small aircraft single-handedly. Conrad was an engineer and tinkerer at heart.

Education-wise, he would partly follow in his father’s footsteps: the private Haverford School, from which he was expelled, then the Darrow School in New York, where Conrad’s dyslexia was identified and where he shone. Although his father intended him to attend Yale University, he actually enrolled in 1949 at Princeton, with a Reserve Officers Training Corps (ROTC) scholarship from the Navy to pay for his studies in aeronautical engineering. Graduation in 1953 brought him not only his bachelor’s degree, but also a pilot’s licence with an instrument rating, marriage (to Jane DuBose) and entrance into naval service.

He breezed through flight training, earning the callsign ‘Squarewave’ as a carrier pilot. In ‘Rocketman’, his widow wrote that Al Teddeo, executive officer of Fighter Squadron VF-43 at Naval Air Station Jacksonville, Florida, had his doubts when he first met the young, seemingly-wet-behind-the-ears ensign one day in 1955. Those doubts were soon laid to rest when Teddeo discovered that Conrad could handle with ease any manoeuvre asked of him. Tactical runs, strafing runs, spin-recovery tests; Ensign Conrad did it all. “Hell, we refuelled three times till I just had to get back to my desk,” Teddeo recalled years later. “It was like telling a kid at the fair that it was time to go home.”

Next came gunnery training at El Centro, California, and transition from jet trainers to the F-9 Cougar fighter, before reporting to Pax River in 1958 to qualify as a test pilot. Later that same year, he received, along with over a hundred others, classified instructions to attend a briefing in Washington, DC. Conrad was told to check into the Rice Hotel under the cover name of ‘Max Peck’. Only when he got there did he find that another 35 ‘Max Pecks’ were also there – including an old naval buddy, Jim Lovell. Neither Conrad nor Lovell would make the final cut for the Mercury selection, but their day would come three years later.

Whereas Lovell was cast aside for a minor liver ailment, however, Conrad’s cause for failure proved a little ironic. “Unsuitable for long-duration flight,’’ read the explanatory note. He had, it seemed, shown a little too much cockiness and independence during testing; characteristics which were at loggerheads with the panel’s notion of a good, all-rounded, level-headed astronaut. Six years after reading those words, Conrad and his Gemini V command pilot, Gordo Cooper, would rocket into space and set a new record… for long-duration spaceflight!

On the ground, the television networks – which had cancelled their showings of ‘Batman’ and, ironically, ‘Lost in Space’ – were deluged with complaints from viewers as attention turned to a dramatic recovery effort. Original plans called for Gemini VIII to land in the Atlantic and be picked up by the aircraft carrier Boxer; however, the earlier-than-expected return called instead for a splashdown in the western Pacific during their seventh orbit.

The timing was strict. Gemini VIII’s flight path had precessed so far westwards that it would be another full day before Armstrong and Scott could reach a location from which they could be easily recovered. Consequently, a naval destroyer named the Leonard F. Mason, based off the coast of Vietnam, was directed to intercept the new splashdown point, 800 km east of Okinawa. It would be the only Gemini splashdown in the Pacific, in a landing zone designated ‘Dash 3’. ‘‘I looked it up in our manuals,’’ wrote Scott. ‘‘Dash 3 was a secondary landing zone in the South China Sea. It was over 6,000 miles away from our primary landing site.’’

It was far from ideal. By this time, John Hodge’s ‘blue’ flight control team had been at their consoles for 11 hours and a second (‘white’) team, headed by Gene Kranz, reported for duty to supervise the end of the mission. Kranz’s team had more experience in recovery procedures than that of Hodge and, had Gemini VIII run to its intended three-day length, he would have overseen re-entry and splashdown anyway. It made sense, therefore, for Kranz to take the helm.

The news of an impending return was met with grim resignation by Armstrong and Scott, who ran through their pre-retrofire checklists with the capcoms at the Coastal Sentry Quebec, Rose Knot Victor and Hawaiian tracking stations. Unlike Gemini V, which had been nursed through a lengthy mission, despite problems, the situation in which Armstrong and Scott found themselves was compounded by a dangerously-low propellant load. By this time, having tested each of the OAMS thrusters in a now-stable Gemini VIII, Armstrong had identified the glitch with the No. 8 unit, which Scott later described as not exhibiting ‘‘a consistent, linear problem… it was really screwed up’’. In fact, the thruster had been off when it should have been on, and vice-versa, on several occasions. The cause, however, would have to wait for the post-flight investigation.

Loading the re-entry flight program into Gemini VIII’s 4,000-word-memory computer was difficult, particularly as it was already overloaded from the rendezvous with the Agena. This required Scott to erase the rendezvous and docking programs, then feed the re-entry data into the computer by means of a keypad and an on-board device known as an auxiliary tape memory unit. As he worked to punch in a series of nine lines of seven-digit numbers, Scott was relieved that the unflappable Jim Fucci, aboard the Coastal Sentry Quebec, was there to watch his every move. ‘‘He read off those numbers as if he was talking about taking a stroll in the park,’’ Scott wrote. ‘‘I entered them quickly so that I could transmit them back to verify with him before we lost contact again.’’

Gemini VIII’s retrorockets duly ignited at 9:45 pm, whilst out of radio contact, high above a remote part of south-central Africa. Worse, retrofire was conducted during orbital darkness, giving Armstrong and Scott no horizon by which to judge alignment. Minutes later, over the Himalayas, the spacecraft entered the tenuous upper atmosphere and as it continued to descend through the steadily thickening air, Scott reported that he could see nothing but a pinkish-orange glow through his window… then haze and, finally, minutes before splashdown, the glint of water! Ten hours and 41 minutes after leaving Cape Kennedy, at 10:22 pm, the spacecraft hit the Pacific with a harsh thump and Scott yelled “Landing Safe!”

Throughout all this – during the launch, rendezvous, docking, crisis with and without the Agena, re-entry and splashdown – Jimmy Mattern’s watch, tightly strapped around Armstrong’s wrist, continued to tick faithfully…

Despite having suffered severe space sickness and, now, seasickness as the spacecraft’s windows rhythmically rolled and pitched with each wave, the astronauts swiftly proceeded through their post-splashdown checklist, shutting down electrical systems, placing switches and valves into their correct positions and activating their high-frequency communications antenna. Only now did Armstrong and Scott regret not taking Mission Control’s advice to swallow meclizine motion sickness tablets before re-entry. “When Mission Control told us about three-foot waves,’’ Scott wrote, “they had forgotten to mention the 20-foot swells!’’

Scott called the search-and-rescue team from Naha Air Base in Okinawa by their callsign ‘Naha Rescue One’, but was met with silence on the radio. Both men were hot in their suits, particularly Scott, whose ensemble had extra layers to provide radiation protection on his spacewalk. Fumes from the ablated heat shield, too, left them nauseous. Within half an hour, a C-54 aircraft, flown by Air Force pilot Les Schneider, which had spotted Gemini VIH’s descent and splashdown, arrived on the scene. Its crew visually checked the spacecraft, marked its landing co-ordinates and dropped three pararescue swimmers and an emergency liferaft. For the Naha Rescue One team, which was more accustomed to missions in Vietnam, Laos and Cambodia in those war-charged times, 16 March 1966 was a distinctly different and highly memorable day.

Notwithstanding the rough swells, the pararescue swimmers, themselves queasy, affixed a flotation collar to the spacecraft, then signalled the C-54 with a ‘thumbs-up’ that Armstrong and Scott were alive and well. This was duly radioed to other aircraft in the area, to the Leonard F. Mason, then to Hawaii, to NASA’s Goddard Space Flight Center and finally to Mission Control in Houston, from where public affairs officer Paul Haney announced the news to an anxious world. Meanwhile, the encounter between the antiquated C-54 and the state-of-the-art Gemini was, said Neil Armstrong, ‘‘the most unusual rendezvous in aviation history’’.

Three hours after splashdown, in the small hours of 17 March, the two astronauts and their spacecraft were safely aboard the Mason. The rough seas, though, had made the hoisting of Gemini VIII difficult, to such an extent that it kept crashing against the side of the destroyer, denting its nose at one point. The Mason’s crew, wrote Scott, had initially been less than happy about being given the task of recovering Gemini VIII. They had just completed a seven-week tour in Vietnam and been given a brief spell of liberty in Okinawa. However, their spirits rose as the realisation set in that the astronauts were safe. In spite of their tiredness and the

effects of nausea, Armstrong and Scott managed smiles and greetings for the crew and were found to be healthy, suffering from minimal dehydration.

They were, however, shaken by what had actually come close to disaster… as, indeed, had many within NASA. Deputy Administrator Bob Seamans had been advised of the crisis over the telephone whilst at the reception to the prestigious Robert H. Goddard Memorial Dinner and swore that he would never again be caught in such a position during the critical phase of a future mission.

At the same time, publicly, NASA was reluctant to over-emphasise the near­disaster, particularly if it wanted continued funding for a Moon landing by 1970. When Life magazine proposed titling its Gemini VIII article as ‘Our Wild Ride in Space by Neil and Dave’, its editor-in-chief received a firm request from Armstrong to change it to something less melodramatic. Ultimately, bound by an ongoing contract, the magazine agreed and would publish watered-down headlines for Gemini VIII and subsequent missions.

In spite of the troubles, President Lyndon Johnson reassured the American public that his administration remained firmly committed to John Kennedy’s goal of bootprints on the Moon before the end of the decade. Some have argued over the years that Armstrong’s coolness was pivotal in his selection to command Apollo 11, although some isolated individuals within the astronaut office speculated that his status as a civilian test pilot had contributed to the failure.

Indeed, Walt Cunningham, later to fly Apollo 7, would criticise what he saw as flaws in both astronauts’ performance, while Tom Stafford felt that the decision to undock from the Agena was a flawed one. Gene Kranz, on the other hand, perceived the crisis as the result of a broader training failure – malfunction procedures did not cover the problems encountered whilst the Gemini and Agena were docked – and both Frank Borman and Wally Schirra praised Armstrong and Scott’s actions as having prevented disaster. Indeed, without their safe return and the knowledge of what had happened, an erroneous assumption that the Agena was to blame could have diseased the final days of Gemini and made it very difficult for Apollo, with its emphasis on rendezvous and docking, to proceed. ‘‘It could have been a showstopper,’’ admitted Dave Scott.

Gene Cernan, though, rationalised the critics’ thinking. ‘‘Screwing up was not acceptable in our hypercompetitive fraternity,’’ he told James Hansen. ‘‘Nobody got a free ride when criticism was remotely possible. Nobody.’’ Still, Gemini VIII did little damage to either man’s career. Definitive testament came two weeks after the flight, when the Gemini VIII Mission Evaluation Team “positively ruled out’’ any errors on the astronauts’ part and, indeed, Bob Gilruth himself praised them for their ‘‘remarkable piloting skill’’. Scott was promoted to lieutenant-colonel and assigned a seat on an Apollo crew within days, while Armstrong received the backup command slot for Gemini XI. Still, the quiet civilian was demoralised by what he saw as only a partial success.

Had he been ‘‘smarter’’, Armstrong said later, he might have figured out the problems earlier, perhaps saving Scott’s EVA and some of the mission’s other objectives. Many of Gemini VIII’s experiments – the zodiacal light photography task, the growth of frogs’ eggs, the synoptic terrain studies, the nuclear emulsions

and the cloud spectrophotography – were left incomplete and some have speculated over the years that, had Scott’s EVA been underway when the spinning started, he may have seen the burst from the stuck-on No. 8 thruster and warned Armstrong to shut off its propellant.

However, others considered it fortuitous that Scott’s EVA had never come to pass. It “had seemed terribly complex and dangerous,’’ wrote Mike Collins. The need for Scott to get outside, manoeuvre himself to Gemini VIII’s adaptor section and worry about swapping connectors and keeping track of tethers was, in Collins’ mind, too risky at such an early stage. “My own EVA scheme on Gemini X was far from ideal,’’ he wrote, “in that I had to stuff everything into an already crowded cockpit, but at least I could make nearly all my preparations inside the pressurised cocoon… Not so with Dave’s complicated gear.’’

Other naysayers have added that, during the uncontrollable spinning, Scott may have been whirled around so violently on his tether as to have hit the side of Gemini VIII, almost certainly producing fatal injuries…

The fire in the AS-204 spacecraft on 27 January 1967 left plenty of blame to go around and both North American, whose workmanship was seen as shoddy, and NASA, who had overseen them and given their seal of approval, were savaged by the media, by the public and by lawmakers alike. The media, indeed, were making up their own stories. On 10 February, for example, Time magazine cited the New York Times as having quoted an unidentified official who claimed that Grissom, White and Chaffee had screamed repeatedly for help in those frantic seconds. Their bodies, the official added, had been incinerated. . .

Fearing that Congress could pull the plug on Apollo with immediate effect, the agency set to work on the night of the disaster on its own internal review, with an eight-man panel headed by Langley Research Center director Floyd Thompson. Although Olin Teague, chair of the House Space Subcommittee, was keen for NASA to complete its work, others within the Senate were impatient and called for a hearing on 27 February. There, Administrator Jim Webb was verbally grilled, with representatives condemning ‘‘the level of incompetence and carelessness” as ‘‘just unimaginable”. Recriminations took an uglier turn when Senator Walter Mondale probed Webb for details of something called ‘The Phillips Report’.

Apollo’s programme manager, a retired Air Force general named Sam Phillips, had strongly criticised North American’s performance as prime contractor for over a year. He considered their relationship with NASA to be quarrelsome and disagreeable and had established a ‘tiger team’ to inspect the situation. This had

left him with serious concerns, so much so that on 16 December 1965 he wrote a scathing memo to North American chairman Lee Atwood, placed the company on notice to improve and told George Mueller, NASA’s associate administrator for the Office of Manned Space Flight, that he had “lost confidence” in the prime contractor. Now, in the spring of 1967, Jim Webb revealed that he had never been made privy to the contents of Phillips’ report.

Others, including North American inspector Thomas Baron, had since 1965 condemned the level of poor workmanship they saw at Cape Kennedy, together with infractions of cleanliness and safety rules. Although Baron’s judgements were refuted by North American in its congressional testimony, they cannot have helped to quieten those who were looking for blame. Some, including the writer Erik Bergaust in his 1968 book ‘Murder on Pad 34’, even implied that NASA had blood on its hands for racing recklessly with the decade and killing the three men in the process.

Against this backdrop of public and media fury, the Thompson board worked for ten weeks, assisted by 1,500 technicians, and traced all possible sources of fire in Apollo’s 30 km of electrical wiring and even re-enacted the blaze in a command module mockup. Additionally, Spacecraft 014, the Block 1 vehicle originally assigned to Wally Schirra’s Apollo 2 mission, was shipped from Downey to Cape Kennedy for systematic dismantling and inspection alongside the burnt-out Spacecraft 012. Cabin pressures, the investigators found, had soared from the normal test pressure of 1.15 bars, slightly above sea-level equivalent, to 2.0 bars, rupturing the spacecraft’s hull, but it was Bureau of Mines expert Robert van Dolah who revealed the damning truth: an escape hatch, capable of being opened in a couple of seconds, might have saved the astronauts. Thompson’s report was published on 9 April and ran to 3,300 pages. It found no definitive cause for the fire, but suspected an unexplained arc on wiring beneath Grissom’s left footrest, which spurted to another object and ignited the 100 per cent oxygen atmosphere.

The report cited ‘‘deficiencies in command module design, workmanship and quality control’’, including uncertified and highly-flammable materials in the cabin, as having contributed to the tragedy. Additionally, it revealed that many safety checks simply were not done, nor was there enough fire-suppression equipment at Pad 34. ‘‘It was,’’ wrote Deke Slayton, ‘‘about as scathing a document as you’d ever see from a government agency towards itself.’’

Days later, Thompson and others found themselves testifying before the House and quickly discovered that even pro-Apollo congressmen were fiercely unsympa­thetic. Some lawmakers even went so far as to suggest reviewing the business of selecting contractors for the lunar effort. At one stage, responding to a question from Congressman John Davis of Georgia, North American’s John McCarthy raised the possibility that Grissom himself might have inadvertently started the fire by kicking a batch of loose wires. Although Slayton admitted that McCarthy’s comment was only raised in response to a question, he wrote that ‘‘it really pissed me off… because there were no grounds for the story – it was pure speculation, not to mention physically impossible’’.

The effect of the fire elsewhere in the space agency was equally dramatic. Bob Gilruth, who had become a virtual father figure to many of the astronauts, broke down in tears upon learning of the tragedy. In his autobiography, Wally Schirra recalled taking him out on for a spin on his Cal 25 sailboat a few months after the accident and, whilst manning the tiller, Gilruth fell asleep. “Maybe it was the first chance he’d had to relax, to realise he had to push ahead and forget the tragedy,” Schirra wrote. “Gilruth was carrying a tremendous load.’’ So too was Joe Shea, the man who might have been inside the command module, sitting in precisely the spot where the fire started that terrible evening. He took the fire very badly, shifting into overdrive in an impossible personal crusade to solve Apollo’s problems… and, in doing so, drove himself to the brink of a breakdown. Eventually, he was moved to NASA Headquarters, then left to work for Raytheon. Years later, Shea would wonder if he could have snuffed out the fire… and convinced himself, with 70 per cent certainty, that he could have successfully smothered it.

It was the straight-talking Frank Borman who summed up what should happen in testimony on 17 April. “Let’s stop the witch hunt,’’ he told Congress, “and get on with it.’’ Getting on, though, would involve more than a year and $75 million-worth of changes to turn Apollo into a very different machine to that in which Grissom, White and Chaffee had died. Its cabin would now be pressurised with a mixture of 60 per cent oxygen and 40 per cent nitrogen, then steadily replaced with pure oxygen at partial pressure after launch as the nitrogen leaked out. No major structural reworking of the command module would be necessary. All flammable materials were to be removed and, crucially, a new 32 kg single-piece hatch was implemented, which opened outwards and could be sprung in just five seconds. Its mechanism, assisted by a cylinder of compressed nitrogen gas, could be opened with a little finger.

Elsewhere, aluminium plumbing, which melted at 580°C, was replaced by stainless steel, and coolant pipelines which could release flammable glycol when ruptured were ‘armour-plated’ with high-strength epoxy. Wire bundles were encased in protective metal panels and nylon netting and plastic containers were replaced by fire-retardant materials such as Teflon. Intricate ‘Velcro maps’ were created to limit the presence of this useful, but highly flammable, material and identify exactly where every piece of it would be located in the command module’s cabin. Paperwork was kept to a minimum, to such an extent that the crews were barred from taking reading materials with them. ‘‘No books or magazines,’’ wrote Wally Schirra. ‘‘Nor could we take anything made of paper to play with, such as cards or puzzles. We would find boredom a serious problem as we progressed through ten days in orbit.’’

The space suits to be worn by the astronauts had their nylon outer coatings replaced by beta cloth – an advanced fibreglass material produced by Owens – Corning Fibreglass Corporation – and supported by 14 layers of fire-resistant material. ‘‘We’re paying a price for safety,’’ Apollo 7 flight director Glynn Lunney told Time magazine. ‘‘The suits are bulkier, the fibreglass itches like hell and the seat belts are difficult to cinch down because they are so stiff, but you are seeing a spacecraft several hundred per cent improved.’’ Further, an emergency venting system capable of reducing the cabin pressure in seconds provided an extra safeguard to snuff out fires. Overall, the changes increased Apollo’s weight by 1,750 kg and placed it just beneath the Saturn V’s total lifting capacity for lunar missions. As a

result, parachutes were enlarged to permit safer splashdowns at greater weights, some redundant systems were eliminated and lead ballast was removed.

By extension, of course, the disaster which had befallen the command module could also afflict Grumman’s lunar module and increased fervour was placed on reviewing its materials, too. Nylon-based items were replaced by beta cloth and ‘booties’ were installed over circuit breakers to lessen the risk of electrical shorts. This work on the lunar module – the machine which would actually set men on the Moon – refocused attention on the key question: would John Kennedy’s dream ever be realised, within the decade, or at all? At the beginning of 1967, NASA had spent $23 billion on Project Apollo and many now questioned the need for America to go there. The continuing threat of the Soviet Union provided one reason: Leonid Brezhnev’s increasingly regressive and repressive regime had, only a year before, consigned writers Yuli Daniel and Andrei Sinyavsky to hard labour for penning satirical, anti-Soviet texts. In some minds, it harked back to far darker times under Stalin.

When physicist Edward Teller was asked by Congress what he expected men to find on the Moon, he replied: ‘‘The Russians!’’ Even now, the sense of fear was as strong as ever. For their part, the Russians, mysteriously, had been conspicuously absent from the manned spaceflight business for almost two years by the time of the Apollo 1 fire, but their ambitions in Earth orbit were ready for a new resurgence. The death of Sergei Korolev and the appearance of a successor, Vasili Mishin, had pushed the Soviet Union’s new spacecraft – Soyuz (‘Union’) – further and further behind schedule. Now, three months after the deaths of Grissom, White and Chaffee, it was ready to go. Or was it?

Although Gemini V, the first to carry and utilise fuel cells for electrical power, had long been planned to fly for seven or even eight days, the success of its predecessor and the performance of Jim McDivitt and Ed White had emboldened NASA to move up their estimates for the first lunar landing from 1970 to 1969 and, perhaps, said Joe Shea, as early as mid-1968. Both Gemini IV astronauts would remain very much part of the unfolding action: White was named within weeks to the backup command slot for Gemini VII, an assignment rapidly followed by the coveted senior pilot’s seat on the maiden Apollo voyage. McDivitt, too, would go on to great things: commanding Apollo 9, a complex engineering and rendezvous flight to pave the way for the first Moon landing. He would even be offered, but would refuse, the chance to walk on the lunar surface himself.

First, though, came the adulation. After an initial Houston reception, they headed for Chicago, where a million people greeted them and showered them in tickertape along State Street and Michigan Avenue. This was followed, in Washington, DC, by another parade down Pennsylvania Avenue to the Capitol, receptions in the Senate, meetings with foreign diplomats and even a free trip to Paris to upstage the appearance of Yuri Gagarin and a mockup of Vostok 1 at 1965’s Air Show. It is unknown to see such scenes as tickertape parades for astronauts today and, perhaps, the only ones in the foreseeable future may be for the men and women who return to the Moon or become the first to tread the blood-red plains of Mars.

In the Sixties, however, every mission was heroic. Moreover, despite the appalling workload and the inevitable strain the astronaut business placed on marriages and families, every man who left Earth’s atmosphere was a fully-fledged hero. Not for nothing did Gerry and Sylvia Anderson name their five Thunderbird heroes after five of the heroes of the Mercury Seven: Alan, Virgil, John, Scott and Gordon. For one of those heroes, Gordo Cooper, and his rookie pilot, Pete Conrad, the reality in the build-up to their mission was one of exhausting 16-hour workdays, plus weekends, and a tight schedule to launch on 1 August 1965, eight weeks after McDivitt and White splashed down. Cooper and Conrad and their backups, Neil Armstrong and Elliot See, had only been training since 8 February, giving them less than six months to prepare for the longest mission yet tried. “We realised they needed more time,” wrote Deke Slayton. “I went to see George Mueller to ask him for help and he delayed the launch by two weeks.”

Despite the pressure, Cooper and Conrad found time to give some thought to names for their spacecraft, even though NASA had officially barred them from doing so. Due to its pioneering nature, the two men wanted to call Gemini V ‘The Conestoga’, after one of the broad-wheeled covered wagons used during the United States’ push westwards in the 18th and 19th centuries. Their crew patch, in turn, would depict one such wagon, emblazoned with the legend ‘Eight Days or Bust’. This was quickly vetoed by senior managers, who felt it suggested a flight of less than eight days would constitute a failure, and Conrad’s alternative idea – ‘Lady Bird’ – was similarly nixed because it happened to be the nickname of the then-First Lady, wife of President Johnson. Its possible misinterpretation as an insult could provoke unwelcome controversy which NASA could ill-afford. The astronauts, however, would not be put off and Cooper pleaded successfully with Jim Webb to approve the Conestoga-wagon patch, although the administrator greatly disliked the idea. The duality of the word ‘bust’ as denoting both a lack of success and the female breasts did not help matters, either. . .

Preparations for Gemini V had already seen Conrad gain, then lose, the chance to make a spacewalk. According to a January 1964 plan, the Gemini IV pilot would depressurise the cabin, open the hatch and stand on his seat, after which an actual ‘egress’ would be performed on Gemini V (Conrad’s mission), a transfer to the back of the spacecraft and retrieval of data packages on Gemini VI and work with the Agena-D target vehicle on subsequent flights. Following the Voskhod 2 success, however, plans for a full egress were accelerated and granted to Ed White. The result: instead of ‘Eight Days or Bust’, Gemini V would come to be described by Cooper and Conrad as ‘Eight Days in a Garbage Can’; they would simply ‘exist’ for much of their time aloft, to demonstrate that human beings could survive for at least the minimum amount of time needed to get to the Moon and back. (The maximum timespan for a lunar mission, some 14 days, would be an unwelcome endurance slog earmarked for the Gemini VII crew.)

Yet the Conestoga mission did have its share of interesting gadgets: it would be the first Gemini to run on fuel cells, would carry the first production rendezvous radar and was scheduled to include exercises with a long-awaited Rendezvous Evaluation Pod (REP). Originally, it was also intended to fly the newer, longer-life OAMS thrusters, although these were ready ahead of schedule and incorporated into Gemini IV. Only weeks after Cooper, Conrad, Armstrong and See began training, on 1 April 1965 fabrication of the Gemini V capsule was completed by McDonnell,

tested throughout May in the altitude chamber and finally delivered to Cape Kennedy on 19 June. Elsewhere, GLV-5 – the Titan booster assigned to launch the mission – was finished in Baltimore, accepted by the Air Force and its two stages were in Florida before the end of May. Installation on Pad 19 followed on 7 June, the day of McDivitt and White’s splashdown, and Gemini V was mounted atop the Titan U on 7 July. Five days later, the last chance for an EVA on the mission and, indeed, on Geminis VI and VII, was rejected by NASA Headquarters. There seemed little point in repeating what White had already done and, further, Cooper and Conrad, not wishing to be encumbered by their space suits for eight days, had campaigned vigorously for greater comfort in orbit by asking to wear helmets, goggles and oxygen masks. The launch of Gemini V was scheduled for 19 August.

It would be a false start. Thunderstorms ominously approached the Cape, rainfall was copious and a lightning strike caused the spacecraft’s computer to quiver. The latter, provided by IBM, had caused concern on Gemini IV and, this time around, had been fitted with a manual bypass switch to ensure that the pilots would not be left helpless again. The attempt was scrubbed with barely ten minutes remaining on the countdown clock and efforts to recycle for another try on 21 August got underway. On this second attempt, no problems were encountered. Aboard Gemini V, Cooper turned to Conrad. “You ready, rookie?’’ Conrad, white as a sheet, replied that he was nervous. Surely the decorated test pilot who had flown every supersonic jet the Navy owned wasn’t scared? Conrad milked the silence in the cabin for a few seconds, then burst out laughing. “Gotcha!” he said with his trademark toothy grin. “Light this son-of-a-bitch and let’s go for a ride!’’ And ride they did. At 8:59:59 am, Cooper and Conrad were on their way.

Ascent was problematic when noticeable pogo effects in the booster jarred the men for 13 seconds, but smoothed out when the second stage ignited and were minimal for the remainder of the climb. Six minutes after launch, as office workers across America snoozed away their Saturday morning, Gemini V perfectly entered a 163-349 km orbit. Nancy Conrad wrote that her late husband compared the instant of liftoff to “a bomb going off under him, then a shake, rattle and roll like a ’55 Buick blasting down a bumpy gravel road – louder than hell’’.

Hitting orbit made Cooper the first man to chalk up two Earth-circling missions. (Gus Grissom, of course, had piloted a suborbital flight on Liberty Bell 7, before commanding the orbital Gemini 3.) However, Gemini V would shortly encounter problems. The flight plan called for the deployment of the 34.5 kg REP, nicknamed ‘The Little Rascal’, from the spacecraft’s adaptor section, after which Cooper would execute a rendezvous test, homing in on its radar beacon and flashing lights. Before the REP could even be released, as Gemini V neared the end of its first orbit, Conrad reported, matter-of-factly, that the pressure in the fuel cells was dropping rapidly from its normal 58.6-bar level. An oxygen supply heater element, it seemed, had failed. Nonetheless, as they passed over Africa on their second orbit, Cooper yawed the spacecraft 90 degrees to the right and, at 11:07 am, explosive charges ejected the REP at a velocity of some 1.5 m/sec. Next, the flight plan called for Gemini V to manoeuvre to a point 10 km below and 22.5 km behind the REP, although much of this work was subsequently abandoned. However, Chris Kraft’s ground team was becoming increasingly concerned as the fuel cell pressures continued to decline and when a pressure of 12.4 bars was reached this was insufficient to operate the radar, radio and computer. Kraft had little option but to tell the astronauts to cancel their activities with the pod.

It seemed likely that a return to Earth would be effected and Kraft ordered four Air Force aircraft to move into recovery positions in the Pacific for a possible splashdown some 800 km north-east of Hawaii. A naval destroyer and an oiler in the region were also ordered to stand by. Keenly aware of the situation, Cooper radioed that a decision needed to be made over whether to abort the mission or power down Gemini V’s systems and continue, to which Kraft told him to shut off as much as he could. All corrective instructions proved fruitless: neither the automatic or manual controls for the fuel cell’s oxygen tank heater would function. Nor could the heater itself, located in the adaptor section, be accessed by the crew. Cooper and Conrad even manoeuvred their spacecraft such that the Sun’s rays illuminated the adaptor, in the hope that it might stir the system back to life. It was all in vain.

By now, most of their on-board equipment – radar, radio, computer and even some of the environmental controls – had been shut down and, as Gemini V swept over the Atlantic on its third orbital pass, there was much speculation that a re-entry would have to be attempted before the end of the sixth circuit, since its flight track thereafter would take it away from the Pacific recovery area. Then, as the astronauts passed within range of the Tananarive tracking station in the Malagasy Republic, off the east coast of Africa, Cooper reported that pressures were holding at around 8.6 bars, suggesting, Kraft observed, that “the rate of decrease is decreasing”. As he spoke, the oxygen pressures dropped still lower, to just 6.5 bars, and fears were high that if they declined much further, Gemini V would need its backup batteries to support another one and a half orbits and provide power for re-entry and splashdown. The astronauts were asked to switch off one of the fuel cells to help the system and as they entered their sixth orbit the pressures levelled-out at 4.9 bars.

Capcom Jim McDivitt asked Cooper for his opinion on going through another day under the circumstances. “We might as well try it,’’ replied Cooper, but Kraft remained undecided. After weighing all available options, including the otherwise satisfactory performance of the cabin pressure, oxygen flow and suit temperatures, together with the prestige to be lost if the mission had to be aborted, he and his control team emerged satisfied that oxygen pressures had stabilised at 4.9 bars. If there were no more drops, Gemini V would be fine to remain in orbit for a ‘drifting flight’, staying aloft just long enough to reach the primary recovery zone in the Atlantic, sometime after its 18th orbit. Admittedly, with barely 11 amps of power, only a few of the mission’s 17 experiments could be performed, but Kraft felt ‘‘we were in reasonably good shape. . . we had the minimum we needed and there was a chance the problem might straighten itself out’’. As Cooper and Conrad hurtled over Hawaii on their fifth orbit, he issued a ‘go’ for the mission to proceed.

With the reduced power levels, the REP, which kept the spacecraft company up until its eighth orbit, was useless for any rendezvous activities. ‘‘That thing’s right with us,’’ Cooper told Mission Control during their sixth circuit of Earth. ‘‘It has been all along – right out in back of us.’’ Two orbits later, Conrad turned Gemini V a full 360 degrees, to find that the pod had re-entered the atmosphere to destruction. Nonetheless, Gemini V’s radar did successfully receive ranging data from the REP for some 43 minutes.

As the mission entered its second day, circumstances improved and oxygen pressures climbed. “The morning headline,” Kraft radioed the astronauts on 22 August, referring to a newspaper, “says your flight may splash down in the Pacific on the sixth orbit.” Having by now more than tripled that number of orbits, Conrad replied that he was “sorry” to disappoint the media. Despite the loss of the REP, on their third day aloft Cooper conducted four manoeuvres to close an imaginary ‘gap’ between his spacecraft and the orbit of a phantom Agena-D target. This ‘alternate’ rendezvous had been devised by the astronaut office’s incumbent expert, Buzz Aldrin. Cooper fired off a short burst from the aft-mounted OAMS thrusters to lower Gemini V’s apogee by about 22 km, then triggered a forward burn to raise its perigee by some 18 km and finally yawed the spacecraft to move it onto the same orbital plane as the imaginary target. One final manoeuvre to raise his apogee placed Gemini V in a co-elliptical orbit with the phantom Agena. Were it a ‘real’ target, he would then have been able to guide his spacecraft through a precise rendezvous. Such exercises would prove vital for Gemini VI, which was scheduled to hunt down a ‘real’ Agena-D in October 1965, and one of the greatest learning experiences, said Chris Kraft, ‘‘is being able to pick a point in space, seek it out and find it’’.

Notwithstanding the successes, the glitches continued. On 25 August, two of the eight small OAMS thrusters jammed, requiring Cooper to rely more heavily on their larger siblings and expend considerably more propellant than anticipated. It was at around this time that Gemini V broke Valeri Bykovsky’s five-day endurance record and Mission Control asked Cooper if he wanted to execute ‘‘a couple of rolls and a loop’’ to celebrate; the laconic command pilot, however, declined, saying he could not spare the fuel and, besides, ‘‘all we have been doing all day is rolling and rolling!’’ When the record of 119 hours and six minutes was hit, Kraft blurted out a single word: ‘‘Zap!’’ Gordo Cooper, with an additional 34 hours from Faith 7 under his belt, was now by far the world’s most flown spaceman. His response when told of the milestone, though, was hardly historic: ‘‘At last, huh?’’

The dramatic reduction of available propellant made the last few days little more than an endurance run. Kraft told the astronauts to limit their OAMS usage as much as possible and many of their remaining photographic targets – which required them to manoeuvre the spacecraft into optimum orientations – had to be curtailed. Still, a range of high-quality imagery was acquired. The hand-held 70 mm Hasselblad flew again to obtain photographs of selected land and near-shore areas and, of its 253 images, some two-thirds proved useful in post-mission terrain studies. These included panoramas of the south-western United States, the Bahamas, parts of south-western Africa, Tibet, India, China and Australia. Images of the Zagros Mountains revealed greater detail than was present in the official Geological Map of Iran. Cooper and Conrad also returned pictures of meteorological structures – including the eye of Hurricane Doreen, brewing to the east of Hawaii – together with atmospheric ‘airglow’. In addition, they took pictures of the Milky Way, the zodiacal light and selected star fields. Other targets included two precisely-timed Minuteman

missile launches and infrared imagery of volcanoes, land masses and rocket blasts.

The scientific nature of many of these experiments did not detract – particularly in the eyes of the Soviet media – from the presence of a number of military-sponsored investigations. Cooper and Conrad’s flight path carried them over North Vietnam 16 times, as well as 40 times over China and 11 times over Cuba, prompting the Soviet Defence Ministry’s Red Star newspaper to claim that they were undertaking a reconnaissance mission. The situation was not helped by President Johnson’s decision, whilst the crew was in orbit, to fund a major $1.5 billion Air Force space station effort, known as the Manned Orbiting Laboratory (MOL). Among the actual military experiments undertaken by Gemini V were observations of the Minuteman plume and irradiance studies of celestial and terrestrial backgrounds, together with tests of the astronauts’ visual acuity in space to follow up on reports that Cooper had made after his Faith 7 mission. Large rectangular gypsum marks had been laid in fields near Laredo, Texas, and Carnarvon, Australia, although weather conditions made only the former site visible.

Cardiovascular experiments performed during the mission would reveal that both men lost more calcium than the Gemini IV crew, although principal investigator Pauline Beery Mack expressed reluctance to predict a ‘trend’, since “a form of physiological adaptation may occur in longer spaceflight”. Medically, Chuck Berry’s main concerns were fatigue and his advice was that they get as much sleep as possible. ‘‘I try to,’’ yawned Conrad at one stage, ‘‘but you guys keep giving us something to do!’’ All in all, they managed between five and seven hours’ sleep at a time and expressed little dissatisfaction with Gemini V’s on-board fare: bite-sized, freeze-dried chunks of spaghetti and meatballs, chicken sandwiches and peanut cubes, rehydratable with a water pistol. An accident with a packet of shrimp, though, caused a minor problem when it filled the cabin with little pink blobs. Conrad even tried singing, out of key, to Jim McDivitt at one point.

Years later, Conrad would recall that the eight-day marathon was ‘‘the longest thing I ever had to do in my life’’. He and Cooper had spent the better part of six months training together, so ‘‘didn’t have any new sea stories to swap with one another… there wasn’t a whole lot of conversation going on up there’’. Nancy Conrad would recall her late husband describing how the confined cabin caused his knees to bother him – their sockets felt as if they had gone dry – and that he would have gone ‘‘bananas’’ if asked to stay aloft any longer. (Ironically, on two future missions, Conrad would stay aloft for much, much longer. . . but on those occasions, his tasks would include a couple of meandering trots around the lunar surface and floating inside a voluminous space station.) He found it hard to sleep, hard to get comfortable and the failures meant he and Cooper spent long periods simply floating with nothing to do. After the flight, he told Tom Stafford that he wished he had taken a book, and this gem of experience would be noted and taken by the crew assigned to fly the 14-day mission.

Nancy Conrad described Cooper’s irritation at losing so much of his mission. He was far from thrilled that the two main tasks for Gemini V, rendezvous and long – duration flight, were becoming little more than ‘‘learning-curve opportunities’’ and suggested throwing an on-board telescope in the Cape Kennedy dumpster when it twice refused to work. Later, when the spacecraft was on minimum power and the astronauts were still expected to keep up with a full schedule, Cooper snapped “You guys oughtta take a second look at that!” As for physical activity, he grimaced that his only exercise was chewing gum and wiping his face with a cleansing towel.

On the ground, Deke Slayton was concerned that such an attitude would not help Cooper’s reputation with NASA brass. Indeed, Gemini V would be his final spaceflight and, although he would later complain bitterly about ‘losing’ the chance to command an Apollo mission, some within the astronaut corps would feel that Cooper’s performance and strap-it-on-and-go outlook had harmed his career. Tom Stafford was one of them. ‘‘Gordo… had a fairly casual attitude towards training,’’ he wrote, ‘‘operating on the assumption that he could show up, kick the tyres and go, the way he did with aircraft and fast cars.’’

To spice matters up still further, worries about the fuel cells continued to plague Gemini V’s final days. Their process of generating electricity by mixing hydrogen and oxygen was producing 20 per cent too much water, Kraft told Conrad, and there were fears that the spacecraft was running out of storage space. This water excess might back up into the cells and knock them out entirely. In order to create as little additional water as possible, the astronauts powered down the capsule from 44 to just 15 amps and on 26 August Kraft even considered bringing them home 24 hours early, on their 107th orbit. However, by the following day, the water problem abated, largely due to the crew drinking more than their usual quota and urinating it into space, and a full-length mission seemed assured.

Eitherway, they had long since surpassed Bykovsky’s Vostok 5 record. In fact, by the time Cooper and Conrad splashed down, they would have exceeded the Soviets on several fronts: nine manned missions to the Reds’ eight, a total of 642 man-hours in space to their 507 and some 120 orbits on a single mission to their 81. At last, after eight years in the shadows – first Sputnik, then Gagarin, Tereshkova, Voskhod 1 and Leonov – the United States was pulling ahead into the fast lane of the space race. When it seemed that Gemini V might come home a day early and miss the scheduled Sunday 29 August return date, mission controllers in Houston even played the song ‘Never on Sunday’, together with some Dixieland jazz.

The astronauts also had the opportunity on the last day of the mission to talk to an ‘aquanaut’, Aurora 7 veteran Scott Carpenter, who was on detached duty to the Navy. Carpenter, who had broken his arm in a motorcycle accident a year before and been medically grounded by NASA, was partway through a 45-day expedition in command of Sealab II, an underwater laboratory on the ocean floor, just off the coast of La Jolla, California. The Sealab effort, conceived jointly by the Navy and the University of California’s Scripps Institution of Oceanography, sought to discover the capacity of men to live and work effectively at depth. In doing so, Carpenter became the first person to place ‘astronaut’ and ‘aquanaut’ on his career resume. Yet, unlike Cooper and Conrad, his chances of returning to space were non­existent. He had not impressed senior NASA managers with Aurora 7 and, indeed, the partial success of an operation to repair the injury to his arm meant he would remain grounded anyway. He resigned from NASA in early 1967.

The music, the chat with Carpenter and even Conrad’s dubious singing did little

to detract from the uncomfortable conditions aboard the capsule. As they drifted, even with coolant pipes in their suits turned off, the two men grew cold and began shivering. Stars drifting past the windows proved so disorientating that they put covers up. Sleep was difficult. Chuck Berry had wired Conrad with a pneumatic belt, a blood-pressure-like cuff, around each thigh, which automatically inflated for two minutes of every six throughout the entire mission. The idea was that, by impeding blood flow, it forced the heart to pump harder and gain its much-needed exercise. Berry felt that if Conrad came through Gemini V in better physical shape than Cooper, who did not wear the belt, a solution may have been found for ‘orthostatic hypotension’, the feelings of lightheadedness and fainting felt by some astronauts after splashdown.

For the two astronauts, that splashdown could not come soon enough. By landing day, 29 August, their capsule had become cluttered with rubbish, including the litter of freeze-dried shrimp, which had escaped earlier in the mission. The appearance of Hurricane Betsy over the prime recovery zone prompted the Weather Bureau to recommend bringing Gemini V down early and Flight Director Gene Kranz agreed to direct the Lake Champlain to a new recovery spot. At 7:27:43 am, Cooper fired the first, second, third, then fourth OAMS retrorockets, then gazed out of his window. It felt, he said later, as if he and Conrad were sitting ‘‘in the middle of a fire’’. Since it was orbital nighttime, they had no horizon and were entirely reliant upon the cabin instruments to control re-entry. In fact, Gemini V remained under instrument control until they passed into morning over Mississippi.

Cooper held the spacecraft at full lift until it reached an altitude of 120 km, then tilted it into a bank of 53 degrees; whereupon, realising that they were too high and might overshoot the splashdown point, he slewed 90 degrees to the left to create more drag and trim the error. Although experiencing a dynamic load of 7.5 G after eight days of weightlessness, the astronauts did not, as some had feared, black out. The parachute descent was smooth. No oscillations were evident and the 7:55:13 am splashdown, though 170 km short of the planning spot, was soft. As would later be determined, the computer had been incorrect in indicating that they would overshoot. A missing decimal point in a piece of uplinked data had omitted to allow for Earth’s rotation in the time between retrofire and splashdown. In fact, Cooper’s efforts to correct the false overshoot had progressively drawn them short of the recovery zone. ‘‘It’s only our second try at controlling re-entry,’’ admitted planning and analysis officer Howard Tindall. ‘‘We’ll prove yet that it can be done.’’

Gemini V had lasted seven days, 22 hours, 55 minutes and 14 seconds from its Pad 19 launch to hitting the waves of the western Atlantic and the crew was safely aboard the Lake Champlain by 9:30 am. With the exception of the failed REP rendezvous, and one experiment meant to photograph the target, all of Cooper and Conrad’s objectives had been successfully met. Yet more success came when Chuck Berry realised that, despite the days of inactivity with little exercise aboard the capsule, the astronauts were physiologically ‘back to normal’ by the end of August, clearing the way for Frank Borman and Jim Lovell to attempt a 14-day endurance run on Gemini VII in early 1966. First, though, Wally Schirra and Tom Stafford would fly Gemini VI for one or two days in October and complete the first rendezvous with an

Agena-D target. The mission – or, rather, missions – that would follow would snatch victory from the jaws of defeat and set aside another obstacle on the path to the Moon. But not before suffering a major setback of its own.

One saving grace of the crisis was that Scott had the presence of mind, before undocking, to switch over command of the Agena to Mission Control. The result: the Gemini VIII-Agena Target Vehicle (GATV-VIII) could – and would – be reused during a subsequent mission. Four months later, Gemini X’s John Young and Mike Collins would fly part of their own rendezvous, docking and spacewalking extravaganza with the Agena. In the days after Armstrong and Scott splashed down, the rocket’s main engine was fired ten times, its various systems were vigorously tested and it successfully received and executed more than 5,400 commands. By 26 March, its electrical power had been exhausted and it could no longer be effectively controlled, but by this stage it had been raised into a higher orbit to permit inspection by the Gemini X crew.

Before Young and Collins could complete their mission, however, came Gemini IX; stricken, it seemed, by bad luck since the dull, chill February day when its prime crew lost their lives in St Louis. Days after the deaths of Elliot See and Charlie Bassett, their backups, Tom Stafford and Gene Cernan, were appointed to replace them. With a launch scheduled for mid-May, Stafford would record the shortest turnaround between flights of any space traveller thus far, blasting off just five months after his Gemini VI-A splashdown. Newly-promoted to become the ‘new’ Gemini IX backups were Jim Lovell and Buzz Aldrin, who, by following Deke Slayton’s three-flight crew rotation system, were now in prime position to fly the Gemini XII mission in November 1966.

Gemini XII, the last flight in the series, was originally to be the preserve of Stafford and Cernan in their capacity as See and Bassett’s backups. In fact, in his autobiography, Cernan recalled trips to McDonnell’s plant in St Louis to inspect and train on the Gemini IX capsule. . . yet finding himself, in rare moments of spare time, drifting down the line of almost-complete spacecraft to take a wistful look at the skeletal form of Gemini XII, his and Stafford’s ship. Years later, Cernan would still recall his desire to know every switch, every circuit breaker, every instrument, every bolt and rivet, inside the Gemini before he and Stafford took this engineering marvel into the heavens.

The prime and backup crews for Gemini IX were announced in early November 1965 and, indeed, with Stafford still busy preparing for his mission with Wally Schirra, Cernan was forced to train alone with See and Bassett until early the following year. His role not only shadowed Bassett, but prepared himself for the possibility, however remote, of actually flying the mission and conducting a lengthy EVA wearing an Air Force contraption known as the Astronaut Manoeuvring Unit (AMU). It looked, Cernan wrote, “like a massive suitcase” that was “so big that it would be carried aloft folded up like a lawn chair and attached within the rear of the Gemini”. (In fact, the Air Force’s project officer for the AMU, Major Ed Givens, was selected by NASA as an astronaut candidate in April 1966.)

Having manoeuvred himself over to the device, Bassett would “slip onto a small bicycle-type seat, strap on the silver-white box and glide off into space, manoeuvring with controls mounted on the armrests’’. Sounding very much like something from a Buck Rogers episode, the AMU had evolved through seven years of developmental work, with its focus on military tasks associated with a Pentagon-sponsored space station called the Manned Orbiting Laboratory. “The possibility of using it to send someone scooting off to disable an enemy satellite,’’ wrote Cernan, “wasn’t mentioned in public because we weren’t supposed to be thinking about the militarisation of space.’’

For NASA’s purposes, however, the 75 kg AMU provided an essential tool in understanding how effectively astronauts could work and manoeuvre outside the confines of their spacecraft. When he was named to Gemini IX, Bassett was tasked with an EVA that would span at least one 90-minute circuit of the globe and would be able to control his movements and direction by means of 12 hydrogen peroxide thrusters. The AMU was also equipped with fuel tanks, lights, oxygen supplies, storage batteries and radio and telemetry systems. The device would be controlled by knobs on the end of the AMU’s twin arms – a left-hand one providing direction of motion, a right-hand one for attitude – although, for safety, Bassett would remain attached to Gemini IX by a 45 m tether throughout the spacewalk.

Undoubtedly raising Cernan’s hopes for his own mission was the possibility that, if Bassett’s excursion went without a hitch, plans were afoot for a more autonomous AMU spacewalk on Gemini XII, perhaps untethered. In the days before enormous water tanks became the norm for EVA training, Bassett and Cernan spent much of their time physically conditioning themselves. Both men recognised that vast reserves of strength and stamina would be required to handle the demands of a spacewalk encased inside a bulky pressurised suit and resorted to lengthy spells in the gym, games of handball and hundreds of press-ups. “Before long,’’ Cernan wrote, “we grew Popeye-sized forearms.’’

Their suits needed to be somewhat different from that worn by Ed White on Gemini IV, partly in recognition of the demands of the AMU, as well as to provide additional comfort and protection. The new ensembles included a white cotton long – john-type undergarment for biosensors, a nylon ‘comfort’ layer, a Dacron-Teflon link net to maintain the suit’s shape and several layers of aluminised Mylar and nylon for thermal and micrometeoroid protection. Guarding them from the searing hydrogen peroxide plumes from the AMU (one of which would jet directly between

Bassett’s legs!) were the heat-resistant ‘trousers’ of the suit. These were composed of 11 layers of aluminised H-film and fibreglass, topped by a metallic fabric woven from fibres of the alloy Chromel R. One day during training, Bassett and Cernan watched as a technician charred the material with a blowtorch for five minutes, telling them that despite the intense temperature of the AMU’s exhausts, they would remain comfortable within their suits.

As Cernan continued his training as Bassett’s understudy, the pair – indeed, the foursome, if one also counted See and Stafford – spent so much time working together than a relationship akin to family developed. Despite their intense focus on Gemini IX, Stafford and Cernan undoubtedly looked forward to their own rendezvous, docking and spacewalking adventure with their own Gemini, their own Agena and their own AMU, towards the end of 1966. All that changed on the morning of 28 February, when it became clear that Cernan’s first journey into space would come much sooner, more unexpectedly and more horrifyingly, than he could have ever imagined or wished.

On the evening that the Apollo 1 crew lost their lives, the astronaut office in Houston was unusually quiet. At one point, only Al Bean was on duty and it was he who received the first word from Cape Kennedy of the fire. Several other astronauts were at Downey, California, running through simulations and practice for their missions… and a select delegation was at the White House in Washington, DC. There, veteran astronauts Scott Carpenter, Gordo Cooper, Jim Lovell, Neil Armstrong and Dick Gordon witnessed the signing by President Johnson of a document popularly called ‘The Outer Space Treaty’. Four decades later, the document has around a hundred signatories and a further two dozen who are partway through their ratification of it.

Officially, it is known as ‘The Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, Including The Moon and Other Celestial Bodies’. Essentially, the document forms the basis for the earliest international space law and on the very day that Grissom, White and Chaffee died, it was opened for signing by the United States, Great Britain and the Soviet Union. Its 17 articles decree that signatories will refrain from the placement of nuclear weapons or weapons of mass destruction into Earth orbit, onto the Moon or onto any other celestial body. The treaty explicitly states that the Moon and other celestial bodies are to be used for peaceful purposes and forbids weapons-testing and military exercises or implacements on them. Moreover, it denies signatories the right to ‘claim’ a celestial resource, such as the Moon, as its own and declares all to be “province of mankind’’. It also assures the safe and cordial return of any astronauts or cosmonauts who make an unexpected landing within the borders of another nation.

The astronauts liked to call it the ‘‘non-staking-a-claim treaty’’ and as the afternoon wore into evening, they mingled with guests at the event, including ambassadors from the Soviet Union (Anatoli Dobrynin), Great Britain (Patrick Dean) and Austria (Kurt Walheim, later Secretary-General of the United Nations). In his biography of Armstrong, James Hansen noted the astronaut’s recollection that the event ended at 6:45 pm and that, with the exception of Carpenter, the NASA delegation returned to the Georgetown Inn on Wisconsin Avenue. When they got to their rooms, they were greeted by flashing red lights on their answer machines. Something terrible had happened in Florida. A difficult year lay ahead.

Gordo Cooper and Pete Conrad had flown the equivalent of a minimum-duration lunar flight and, indeed, one of them would tread its dusty surface in a little over four years’ time. Apart from stiff joints, heavy beards, a tendency to itch and an aroma, like that of McDivitt and White, which seemed somehow ‘different’ from everyone else on the recovery ship, they were fine. Cooper, whose heart averaged 70 beats per minute, had come through Gemini V in better shape than Faith 7. After eight days in a half-sitting, half-lying position, both men managed to do some deep-knee bends aboard the recovery helicopter, hopped onto the deck of the Lake Champlain without assistance and walked without wobbling.

They had, NASA flight surgeons determined, come through the mission less fatigued than the Gemini IV crew. This was at least partly because Cooper and Conrad got around six hours’ sleep per night during the early portion of their flight. However, their weight loss was perplexing: Cooper had lost 3.4 kg and Conrad 3.8 kg whilst aloft. They had, admittedly, only eaten 2,000 calories per day, rather than the scheduled 2,700, and drank their quotas of water, but both regained the lost weight within days. Still, neither exhibited signs of orthostatic hypotension and Chuck Berry asserted that ‘‘we’ve qualified man to go to the Moon’’.

Those plans received an abrupt setback on 25 October 1965.

When Wally Schirra and Tom Stafford were assigned to Gemini VI, they were told by Deke Slayton that their two-day mission would feature the world’s first rendezvous with a Lockheed-built Agena-D target. Their backups, Gemini 3 fliers Gus Grissom and John Young, had been picked because Slayton ‘‘wanted a veteran backup crew to help with training’’. In his autobiography, Stafford would recall that Young sat actively through simulations with them, whereas Grissom was often absent, racing cars or boats. After three years working on Gemini, Grissom now had his sights set on commanding the first Apollo mission. Following Gemini VI would come Gemini VII, sometime early in 1966, flown by Frank Borman and Jim Lovell and backed-up by Ed White and Mike Collins. The decision to fly the first rendezvous mission ahead of the long-duration 14-day flight had come about because of ongoing Agena problems; Charles Mathews wanted assurances that, if anything went wrong on Gemini VI, there would be enough time to resolve it before resuming rendezvous practice from Gemini VIII onwards.

The first Gemini-Agena Target Vehicle (GATV), numbered ‘5001’, was shipped to Cape Kennedy in May 1965, purely as a non-flying test article, and three months later its successor – ‘5002’ – was officially earmarked for Schirra and Stafford’s mission. However, doubts over its reliability lingered. Its main engine, some felt, could not be trusted to execute manoeuvres with a docked Gemini and, although Schirra lobbied for it to go ahead, opposition within NASA to firing it was strong.

Next, Schirra pushed for a firing of the Agena’s less powerful secondary propulsion system, although this was not initially incorporated into the Gemini VI flight plan. To be fair, rendezvous techniques were very much in their infancy in 1965, as demonstrated by the unsuccessful attempt of Jim McDivitt to station-keep with the second stage of his Titan II. Buzz Aldrin, however, was a rendezvous specialist, having completed a doctorate in the field before becoming an astronaut, and he joined forces with Dean Grimm of NASA’s Flight Crew Support Division to plan a so-called ‘concentric rendezvous’ technique for Gemini-Agena missions.

Their plan was for the target to be launched, atop its Convair-built Atlas rocket, into a 298 km circular orbit, after which Schirra and Stafford would be despatched into a lower, ‘faster’, elliptical orbit. ‘‘Two hundred and seventy degrees behind the Agena,’’ wrote Stafford, ‘‘you’d make a series of manoeuvres that would eventually raise the orbit of the Gemini to a circular one below the Agena. Then you’d glide up below the Agena on the fourth revolution. At that time the crew would make a series of manoeuvres to an intercept trajectory, then break to station-keeping and docking.’’ This docking would occur over the Indian Ocean, some six hours into the mission, after which Schirra and Stafford would remain linked for seven hours and return to Earth following their battery-restricted two-day flight. The astronauts wanted to relight the Agena’s engine whilst docked, but NASA managers vetoed it as too ambitious.

During their training at McDonnell’s St Louis plant during the last half of 1965, the astronauts practiced manoeuvres again and again, plotting them on boards. In total, they did more than 50 practice runs and spent many hours rehearsing the actual docking exercise with the Agena-D in a Houston trainer. ‘‘Housed in a six – story building,’’ wrote Schirra, ‘‘it consisted of a full-scale Gemini cockpit and the docking adaptor of the Agena. They were two separate vehicles in an air-drive system that moved back and forth free of friction. We exerted control in the cockpit with small thrusters, identical to those on the spacecraft. We could go up and down, left and right, back and forth. The target could be manoeuvred in those planes as well, though it was inert. It would move if we pushed against it, just as we assumed the Agena would do in space.’’

On one such training session, Schirra hosted Vice-President Hubert Humphrey in the pilot’s seat. The vice-president asked Schirra if their voices could be heard from outside the trainer. When Schirra replied that, no, it was sound-proofed, Humphrey asked if Schirra minded him having a ten-minute nap. When Humphrey awoke, he asked Schirra to tell him what had happened so that he could tell the people outside. ‘‘I was a fan of Hubert Humphrey from that day on,’’ wrote Schirra.

Although barred from naming Gemini VI, Schirra sketched a design for a patch which he and Stafford could wear. It featured the constellation of Orion, which, navigationally, was to play an important part in the rendezvous. ‘‘The patch would be six-sided,’’ Schirra wrote, ‘‘since six was the number of our mission. Orion also appears in the first six hours of right ascension in astronomical terms, a quarter of the way around the celestial sphere.’’

In anticipation of this dramatic mission, processing of Gemini VI’s flight hardware ran smoothly. In April 1965, its launch vehicle, GLV-VI, became the first Titan to be erected in the new west cell at Martin’s vertical testing facility in Baltimore, Maryland. The rocket’s two stages arrived in Florida at the beginning of August and were placed into storage. Schirra and Stafford’s spacecraft arrived at about the same time and was hoisted atop a timber tower for electronic compatibility testing with GATV-5002. Such exercises would later become standard practice in readying Gemini-Agena missions. It was the last Gemini to run on batteries, thus limiting Schirra and Stafford to no more than 48 hours in space, although, by September, NASA was pushing for just one day if all objectives were completed. Even Gemini VI’s experiments – two rendezvous tests (in orbital daytime and nighttime), one medical, three photographic and one passive – were considered secondary to the proximity operations with the Agena. Said Schirra: “On my mission, we couldn’t afford to play with experiments. Rendezvous [was] significant enough!’’

However, so much reliance was being placed on the radar, the inertial guidance platform and the computer that Grimm and Aldrin found the pilot’s role was seriously impaired; if these gadgets failed, wrote Barton Hacker and James Grimwood, so too would the whole mission. Grimm persuaded McDonnell managers to rig up a device which could allow the astronauts to simulate trajectories, orbital insertion and spacecraft-to-Agena rendezvous paths. As a result, Schirra and Stafford were able to participate in no fewer than 50 simulations, conferring with Aldrin on techniques and procedures. Stafford would also recall the admirable efforts of‘Mr Mac’ himself – James McDonnell, founder of the aerospace giant which bore his name – who, upon learning that the astronauts needed more time on the training computers, complied. ‘‘Mr Mac was always behind the programme,’’ Stafford wrote. In fact, he and Schirra invited McDonnell to dinner on the night before the Agena’s, and their own, planned liftoff.

Early on 25 October, out at the Cape’s Pad 14, a team from General Dynamics oversaw the final hours of the Atlas-Agena countdown. The Atlas booster, tipped with the slender, pencil-like Agena, was scheduled to fly at precisely 10:00 am. Meanwhile, Al Shepard, by now the chief astronaut, woke the Gemini VI crew and joined them for breakfast and suiting-up. Schirra, struggling to give up smoking, lit up a Marlborough during the ride to Pad 19. He felt, wrote Stafford, ‘‘he could survive a twenty-four-hour flight without getting the shakes’’. One and a half kilometres to the south, General Dynamics launch manager Thomas O’Malley pressed the firing button for the Atlas-Agena at 10:00 am and the first half of the GTA-VI mission was, it seemed, underway. The countdown had gone without a hitch and, with 140 flights behind it since 1959, the performance of the Agena was unquestioned. The plan was for it to separate from the Atlas high above the Atlantic, then fire its own 7,200 kg-thrust engine over Ascension Island to boost itself into orbit. The complex orchestra of synchronised countdowns would culminate at 11:41 am with Schirra and Stafford’s own liftoff to initiate the rendezvous. Then, things began to go wrong.

The Agena apparently separated from the Atlas, but seemed to wobble, despite the efforts of its attitude controls to stabilise it. Right on time, downlinked telemetry confirmed that its engine had indeed ignited. . . and then nothing more was heard. It

had reached an altitude of some 230 km and was 872 km downrange of Cape Kennedy. Fourteen minutes after launch, it should have appeared to tracking radars in Bermuda, but was nowhere to be seen; except, that is, for what appeared to be five large fragments. Aboard Gemini VI, the astronauts, fully-suited, aboard a fully – fuelled rocket and ready to go, were puzzled. “Maybe it’s the tracking station,” Schirra surmised. “Let’s wait for Ascension Island.’’ As time dragged on, their countdown was held at T-42 minutes, but no sign of the Agena was forthcoming. Ascension Island saw nothing. “No joy, no joy,’’ came an equally dismal report from the Carnarvon station in Australia and NASA’s public affairs officer Paul Haney was forced to tell listeners at 10:54 am that the target vehicle was almost certainly lost. The Gemini VI launch was scrubbed.

In fact, problems had become apparent very soon after the Atlas-Agena left its pad. At 10:06 am, just six minutes into its ascent, Jerome Hammack at the Pad 14 blockhouse was convinced that something was wrong. So too was the Air Force officer in charge of the launch. Although early analysis of the partial telemetry data gave little inkling of what had happened, an explosion seemed the most plausible explanation. “Later investigation,’’ wrote Tom Stafford, “concluded that the Agena had exploded, thanks to an oxidiser feed sequence that had been changed.’’

In Houston, Flight Director Chris Kraft, together with Bob Gilruth and George Low, surveyed the damage. It was clear that if a rendezvous mission was to take place at all, a delay of several weeks simply to identify the cause of the accident would be unavoidable. “And if it turns out to be a major design failure in the Agena,’’ Time magazine drearily told its readers, “the Gemini programme is in deep trouble.’’ Critics argued that the Agena, with a satisfactory track record as a missile, had been extensively modified for its Gemini role and many of these modifications had never been tested in space. A disappointed Schirra and Stafford were quietly extracted from their capsule, to be told by Al Shepard: “Boys, what we need is a good party.’’ It was the perfect answer, to cheer everyone up, so the three men, together with Grissom and Young, headed off into town.

“For a day of so,’’ wrote Deke Slayton, “we thought about recycling Agena 5001, the ground test bird that hadn’t ever come up to specs.’’ However, a lengthy investigation into what went wrong with the 5002 target would still need to be carried out, the results of which would not be clear for weeks. Moreover, a new Agena would not be ready until early 1966. A perfect alternative, however, was on the horizon. Immediately after the Agena’s loss, Frank Borman overheard a conversation between McDonnell officials Walter Burke and John Yardley: the former suggested launching Gemini VII as Schirra and Stafford’s ‘new’ rendezvous target. A study of sending Geminis up in quick succession had been done months earlier and seemed an ideal option, but for one detail. Burke sketched his idea onto the back of an envelope, but Borman doubted the practicality of installing an inflatable cone onto the end of Gemini VII to permit a physical docking. Moreover, George Mueller and Charles Mathews dismissed the entire idea, since it would require the launch of both Geminis within an impossibly tight two-week period.

Other managers thought it could be done. Joseph Verlander and Jack Albert proposed stacking a Titan II and placing it into storage until another had been

assembled. The Titan’s engine contractor, Aerojet-General, had stipulated that the vehicle must remain upright, but this could be achieved with a Sikorsky S-64 Skycrane, after which the entire rocket could be kept on the Cape’s disused Pad 20. Immediately after the first Gemini’s launch from Pad 19, the second Titan stack could be moved into position and sent aloft, conceivably, within five to seven days. The plan, however, held little appeal and received little enthusiastic response, with most attention focused on swapping the 3,553 kg Gemini VI for the 3,670 kg Gemini VII, thereby making good of a bad situation by at least using the Titan II combination already on the pad to fly Borman and Lovell’s 14-day mission.

In the next few days, as this was discussed in the higher echelons of NASA management, it became evident that if the two spacecraft were swapped, the earliest that Borman and Lovell could be launched would be 3 December. However, if the Gemini VII spacecraft were to prove too heavy for the GLV-VI Titan, a delay until around 8 December would become necessary to erect the more powerful GLV-VII. It was then envisaged to launch Schirra and Stafford to perform their rendezvous mission with another Agena sometime in February or early March 1966.

As these plans crystallised, Burke and Yardley posed their joint-flight idea to Bob Gilruth and George Low, who could find few technical obstacles, with the exception, perhaps, that the Gemini tracking network might struggle to handle two missions simultaneously. Even Mathews, when presented with the option, could find few problems, although Chris Kraft’s initial response was that they were out of their minds and it could not be done. Then, having second thoughts, he asked his flight controllers for their opinions, and the most that they could object to was that the Gemini tracking network might struggle to handle two missions. Kraft called his deputy, Sigurd Sjoberg, to discuss the possibility further with the Flight Crew Operations Directorate, headed by Deke Slayton. News filtered down, eventually, to Schirra and Stafford, who heartily endorsed it.

The prospects for Burke and Yardley’s plan steadily brightened when it became clear that the heavy Gemini VII – which, after all, was intended to support a mission seven times longer than Gemini VI – could not be lofted into orbit by Schirra and Stafford’s Titan: it simply was not powerful enough to do the job. Yet the question of tracking two vehicles at the same time remained. Then, another possibility was aired. Could the tracking network handle the joint mission if Gemini VII were regarded as a passive target for Gemini VI? Borman and Lovell would launch first, aboard Gemini VII, and control of their flight would proceed normally as the Gemini VI vehicle was prepared to fly.

As soon as controllers were sure that Gemini VII was operating satisfactorily, they would turn their attention to sending up Gemini VI; in the meantime, Borman and Lovell’s flight would be treated like a Mercury mission, wrote Deke Slayton, “where the telemetry came to Mission Control by teletype, letting the active rendezvous craft have the real-time channels that were available’’. This mode would continue until ‘Gemini VI-A’ – so named to distinguish it from the original, Agena – rendezvousing Gemini VI mission – had completed its tasks and returned to Earth. After Schirra and Stafford’s splashdown, Borman and Lovell would again become the focus of the tracking network.

Before NASA Headquarters had even come to a decision, the rumour mill had already informed the press, some of whom reported the possibility of a dual-Gemini spectacular. On 27 October, barely two days after the Agena failure, Jim Webb, Hugh Dryden, Bob Seamans and other senior managers discussed the idea and George Mueller asked Bob Gilruth to confirm that it would work. The answer was unanimously in the affirmative and Webb issued a proposal for the joint flight to the White House. He informed President Johnson that, barring serious damage to Pad 19 after the Gemini VII launch, Schirra and Stafford’s Titan could be installed, checked out and flown within days to rendezvous with Borman and Lovell. Johnson, residing at his ranch in Austin, Texas, approved the plan on 28 October and his press secretary announced it would fly in January 1966. At NASA, however, December 1965 was considered more desirable.

As October turned to November, preparations gathered pace. Aerojet-General set to work implementing steps by which, contrary to its stipulation, the Titans could be handled in a horizontal position, whilst the Air Force destacked GLV-VI from the pad and placed it in bonded storage under plastic covers at the Satellite Checkout Facility. On 29 October, Gemini VII’s heavy-lift Titan was erected on Pad 19. Guenter Wendt’s first reaction when he saw the short, nine-day Gemini VI-A pad- preparation schedule, was “Oh, man, you are crazy!’’ The Gemini VI-A spacecraft, meanwhile, was secured in a building on Merritt Island. Although Schirra and Stafford’s mission would essentially not change, that of Borman and Lovell was slightly adjusted to circularise its orbit and mimic the Agena’s flight path as closely as possible. Elsewhere, the Goddard Space Flight Center was busy setting up and altering tracking station layouts to enable simultaneous voice communications with both capsules.

At one point, ideas were even banded around for an EVA, in which Lovell and Stafford would spacewalk to each other’s Geminis and land in a different craft. However, Borman had little interest in such capers. His target was a 14-day mission and he had no desire to do anything that would compromise it. Also, he wished to use the new ‘soft’ suits that could be doffed in flight. If a spacewalk were to be added to the flight plan, he and Lovell would have to wear conventional space suits, which would make a 14-day mission an even greater chore. In any case, for Lovell and Stafford to exchange places they would have to detach and reconnect their life – support hoses in a vacuum, leaving them with nothing but their backup oxygen supplies for a while. The bottom line for Borman was that whilst an external transfer might have made great headlines, ‘‘one little slip could have lost the farm’’. Coupled with the fact that Stafford, as one of the tallest of the New Nine, sometimes had difficulty egressing from the capsule during ground tests, the decision was taken to eliminate EVA from the joint mission.

Cernan’s grandparents emigrated to America shortly before the outbreak of the First World War; on his mother’s side, they were Czechs from a Bohemian town south of Prague, while on his father’s side were Slovak peasantry from a place close to the Polish border. Their children, Rose Cihlar and Andrew Cernan, would produce the child who would someday gaze down on Earth through the faceplate of a space suit, would see the sheer grandeur of the lunar landscape and would become one of only a handful of men to go prospecting in the mountains of the Moon.

Eugene Andrew Cernan, a self-described ‘‘second-generation American of Czech and Slovak descent’’, was born in Chicago, Illinois, on 14 March 1934. As a young boy, he learned from his father how machinery worked, how to plant tomatoes, how to hammer a nail straight into a board and how to repair a toilet; all of which instilled in him an ethos ‘‘to always do my best at whatever I put my hand to’’. In high school, that ethos led him to play basketball, baseball and football, for which he was even offered scholarships, but eventually he headed to Purdue University in 1952 to read electrical engineering.

Four years later, Cernan graduated and was commissioned a naval reservist, reporting for duty aboard the aircraft carrier Saipan. After initial flight training, he received his wings of gold as a naval aviator in November 1957 and gained his first experience of flying jets aboard the F-9F Panther. He was subsequently assigned to Miramar Naval Air Station in San Diego and attached to Attack Squadron VA-126, during which time he performed his first carrier landing aboard the aircraft carrier Ranger, flying the A-4 Skyhawk. Then, in November 1958, Cernan participated in his first cruise of the western Pacific, flying Skyhawks from the Shangri-La aircraft carrier, when, ‘‘armed to the teeth and ready for a fight’’, he frequently encountered Chinese MiG fighters in the Straits of Formosa.

Shortly thereafter, the Mercury Seven were introduced to the world and Cernan heard about, and for the first time wondered about, the role of these new ‘astronauts’. In his autobiography, he noted that he met just two of NASA’s requirements – age and degree relevance – and had little of their experience and no test-piloting credentials. ‘‘By the time I earned those kind of credentials,” he wrote, ‘‘the pioneering in space would be over.’’ Still, the germ of a new interest, to become a test pilot and fly rockets, implanted itself in the young aviator’s brain.

In the early summer of 1961, now married to Barbara Atchley, Cernan was approaching the end of his five-year commitment to the Navy when he was offered the opportunity to attend the service’s postgraduate school for a master’s degree in aeronautical engineering. It offered him a route into test pilot school. When NASA selected its second group of astronauts in September 1962 Cernan knew that, although he held the right educational credentials, becoming a test pilot was still years away. Ultimately, however, the decision was made for him when one of his superiors recommended him to NASA for its third astronaut class.

As 1963 drew to a close, and by now the father of a baby daughter, Tracy, whose initials he would one day etch into the lunar dust at the valley of Taurus-Littrow, Cernan was repeatedly summoned to an unending cycle of physical and psychological evaluations and interviews by the space agency. Like so many others before him, he checked into Houston’s Rice Hotel under the assumed name of‘Max Peck’ and sat, ‘‘like a prisoner before the parole board’’, at an interview with such famous men as Al Shepard, Wally Schirra and Deke Slayton. The questions were awkward. ‘‘Someone asked how many times I had flown over 50,000 feet,’’ Cernan wrote. ‘‘Hell, for an attack pilot like me, who had spent his life below 500 feet, that was halfway to space!’’ How to turn the question to his advantage? He flipped it around, telling them that he had flown very low and ‘‘if you’re going to land on the Moon, you gotta get close sometime’’.

He was also getting close to actual selection, as friends began calling to enquire as to why FBI agents had visited them with questions about Cernan’s character, his background, his military record, his educational record, his parking tickets and his disciplinary records. At the same time, he was close to completing his master’s thesis, focusing on the use of hydrogen as a propulsion system for high-energy rockets. Then, just a few weeks before John Kennedy’s assassination, he received the telephone call from Deke Slayton that would truly change his life. Little did he know that one of his Navy buddies, Ron Evans, rejected by NASA on this occasion, would himself be hired in 1966 and the two of them would someday travel to the Moon together.

Cernan’s first two years as an astronaut were spent mired in technical assignments… and, despite being just one of a much larger gaggle of prospective spacegoing pilots, he and his colleagues still benefitted from the Life magazine deal, which nicely supplemented their military salaries. During the early Gemini flights, he occupied the ‘Tanks’ console in Mission Control, overseeing pressurisation and other data for the Titan II’s fuel tanks. Then, one day towards the end of 1965, a technician tapped on his office door and told Cernan that Slayton wanted him to get fitted out for a space suit. The reason was inescapable: a flight assignment, surely, was just around the corner.

On 8 November, it was official: Cernan and Stafford would support Elliot See and

Charlie Bassett, with an expectation that they could then rotate into the prime crew slot for the Gemini XII mission. Four months later, just promoted to lieutenant- commander by the Navy, Cernan had a new assignment. He and Stafford were now the Gemini IX prime crew and it would be Cernan, not Bassett, who would evaluate the AMU rocket armchair during one of the trickiest and most hazardous spacewalks ever attempted.

On 27 April 1967, an unusual communique was issued by the Soviet news agency, Tass. Days earlier, Vladimir Komarov – veteran of Voskhod 1 and the first cosmonaut to make two spaceflights – had been launched into orbit aboard the new Soyuz spacecraft. Within hours, however, euphoria had vanished into tragedy. In a handful of sentences, carefully crafted by the secretary of the Central Committee of the Communist Party, Dmitri Ustinov, it was revealed that Komarov’s ship had ‘‘descended with speed’’ from orbit, ‘‘the result of a shroud line twisting’’. The result: ‘‘the premature death of the outstanding cosmonaut’’. Little more would be known in the western world for nearly three decades and only recently would details begin to trickle out. They would uncover a harrowing tragedy still shrouded in myth, mystery and rumour.

Soyuz was the brainchild of Sergei Korolev, the famous ‘Chief Designer’ of early Soviet spacecraft and rockets, with the original intention that it would support a series of lunar missions to rival the United States’ Apollo effort. When it became increasingly clear that neither the Soyuz, nor an enormous booster rocket needed to reach the Moon, called the ‘N-1’, would be able to beat the Americans, the Soviet paradigm shifted to near-Earth missions: in 1971, they would establish the world’s first space station in orbit. Soyuz would provide a ferry for missions which, by the end of the Seventies, would be routinely spending many months aloft. Four decades later, its basic design remains operational and, heavily modified, continues to transport cosmonauts and astronauts from a variety of nations to and from the International Space Station.

In his 1988 book about the early Soviet space programme, Phillip Clark traced the history of its development back to a three-part ‘Soyuz complex’ – a manned craft, a dry rocket block and a propellant-carrying tanker – which Korolev envisaged in the

early Sixties could be assembled in orbit for circumlunar missions. The first part, known as ‘Soyuz-A’, was closest in appearance to the spacecraft which actually flew. Measuring 7.7 m long, it comprised three sections: a cylindrical orbital module, a bell-shaped descent module to house the crew positions and a cylindrical instrument module for manoeuvring equipment, propellant and electrical systems. According to Korolev’s early blueprints, Soyuz-A weighed around 6,450 kg, but unlike the eventual version it was not fitted with solar panels.

Supporting Soyuz-A were the ‘dry’ Soyuz-B rocket block and the propellant­carrying Soyuz-V tanker. Clark has hinted that a typical flight profile would have begun with the launch of a Soyuz-B, followed, at 24-hour intervals, by up to four Soyuz-Vs, which would dock, deliver their propellant loads, then separate. When the Soyuz-B had been fully fuelled, a manned Soyuz-A would be launched to dock onto the rocket block. ‘‘Mastering rendezvous and docking operations in Earth orbit may have been one of the primary objectives of the Soyuz complex,’’ wrote Asif Siddiqi, ‘‘but the incorporation of five consecutive dockings in Earth orbit to carry out a circumlunar mission was purely because of a lack of rocket-lifting power in the Soviet space programme.’’ Nonetheless, the sheer ‘complexity’ of the Soyuz complex seems to have foreshadowed its restructuring sometime in 1964 and effected a postponement of its maiden voyage until at least 1966. It was as a result of this setback, Clark explained, that the stopgap Voskhod effort was ultimately born.

When Voskhod began with such apparent promise – the world’s first three-man cosmonaut crew, then the first-ever spacewalk – it surprised many in the western world, among them NASA’s astronauts, when nothing more was heard from the Soviets until April 1967. “They hadn’t flown in over two years,’’ wrote Deke Slayton, “which nobody could understand… Some people were beginning to say there wasn’t really a race to the Moon, and on the evidence you had to admit that possibility.” It was Korolev’s successor, Vasili Mishin, who spearheaded the abandonment of Voskhod, which many within the Soviet space programme felt was a diversion of resources from the more versatile Soyuz. “Given what we know about Voskhod,’’ added Slayton, “it was the right decision.’’

By October 1969, seven manned Soyuz spacecraft would have rocketed into orbit. However, a key physical difference between these missions and the original Soyuz-A concept was that they employed a pair of rectangular solar panels, mounted on the instrument module, to generate electrical power. The total surface area of these wing-like appendages was 14 m2, each measuring 3.6 m long and 1.9 m wide. The remainder of the craft’s design was strikingly similar to Soyuz-A: a spheroid orbital module, 2.65 m long and 2.25 m wide, atop the beehive-shaped descent module, itself 2.2 m long and 2.3 m wide at its base. Beneath the descent module was the cylindrical instrument module, 2.3 m long and 2.3 m wide. In total, Soyuz was somewhat larger than Apollo’s command module, yet smaller than the combined command and service module.

Its propulsion system, designated ‘KTDU-35’, consisted of a pair of engines operating from the same fuel and oxidiser supply. The primary engine had a specific impulse of some 2,750 m/sec, equivalent to around 280 seconds’ burn time, and a thrust of 417 kg, with early reports speculating that the propulsion system was capable of lifting Soyuz to an altitude of 1,300 km. This led Clark to suggest that a propellant load of 755 kg would have been required. Propellants took the form of unsymmetrical dimethyl hydrazine and an oxidiser of nitric acid, loaded in tanks on the instrument module. Clark speculated that, for the first few Soyuz missions at least, a lower-than-full propellant supply of around 500 kg was probably carried.

Like Vostok and Voskhod before it, the spacecraft and its three-stage rocket – an uprated version of Korolev’s Little Seven, including four tapering boosters strapped to its central core – were typically delivered to the launch pad horizontally aboard a railcar. The Soyuz’ own propellants were fully loaded before attachment to the rocket’s third stage, after which a payload shroud was installed and, following rollout, the entire combination was tilted into an upright position. Four cradling arms, nicknamed ‘the tulip’, supported the rocket at its base and a pair of towering gantries provided pre-launch servicing access. Cosmonauts entered the spacecraft through its orbital module and dropped down into their seats in the descent module.

Yet the development of this complex spacecraft had been mired in technical and managerial problems since the death of Sergei Korolev in January 1966. Indeed, only days before Soyuz 1 was launched, engineers are said to have reported no fewer than 200 design problems to party leaders, all of which were overruled by the political pressure of getting a cosmonaut back into space. Even Vladimir Komarov, the man who would fly Soyuz 1, is reputed to have said one night in March 1967 that he would not – could not – turn down the assignment, even though he knew the spacecraft was imperfect and his chances of returning alive were slim. His reason: Yuri Gagarin, the first man in space and the Soviet Union’s most treasured hero, was Komarov’s backup. When asked by Gagarin’s KGB friend Venyamin Russayev why he could not simply resign from Soyuz 1, Komarov’s response was simple. “If I don’t make this flight, they’ll send the backup pilot instead,’’ he said slowly. “That’s Yura, and he’ll die instead of me. We’ve got to take care of him.’’

Russayev was so concerned by Komarov’s admission that he spoke to one of his own superiors, Konstantin Makharov, whose department dealt with spaceflight matters relating to personnel. Makharov told him that he intended “to do something’’ and asked Russayev to pass on a letter to Ivan Fadyekin, the head of Department Three, who directed him instead to a close personal friend of Leonid Brezhnev himself, a KGB man named Georgi Tsinev. The letter consisted of a covering note from a team of the cosmonauts, led by Gagarin, together with a ten – page document detailing all 200 problems with Soyuz. “While reading the letter,’’ Russayev was quoted by Jamie Doran and Piers Bizony as saying, “Tsinev looked at me, gauging my reactions to see if I’d read it or not.’’ It seemed to Russayev that Tsinev knew of Soyuz’ inadequacies, but was not interested in the details. “He was glaring at me very intently,’’ Russayev continued, “watching me like a hawk, and suddenly he asked, ‘How would you like a promotion up to my department?’ He even offered me a better office.’’’ Russayev carefully declined the offer and Tsinev kept the document. . . which was never seen again. Makharov was fired, without a pension; Fadyekin was demoted simply for reading the document; and the hapless Russayev was stripped of all space-related responsibilities. ‘‘I kept my head down like a hermit for the next ten years,’’ he said later.

Against this backdrop, Soyuz’ problems had become almost chronic, with difficulties involving its Igla docking system, its simulators, its space suits, its hatches, its parachutes and its environmental controls. At one stage, early in its development, over 2,000 defects awaited resolution. Further, a series of unmanned Soyuz test flights under the ‘Cosmos’ cover name suffered troubles of their own. Phillip Clark noted that, as the break in Soviet manned launches stretched through 1965 and 1966, it became ‘‘almost a sport’’ among analysts to find evidence that a future crewed spacecraft was undergoing trials. Certainly, the flight of Cosmos 133 on 28 November 1966 and that of Cosmos 140 in early February of the following year were strongly suggestive of bearing some link with Soyuz. The first suffered a malfunctioning attitude-control system, which caused rapid fuel consumption and unanticipated spinning. An inaccurate retrofire and the likelihood that it would land in China eventually forced flight controllers to issue a self-destruct command to Cosmos 133. It exploded early on 30 November.

Two months later, Cosmos 140 suffered similar attitude and fuel problems, but at least remained controllable. . . for a while. Its control system malfunctioned during retrofire, producing a steeper-than-intended re-entry which burned a 300 mm hole into the heat shield. The only reason its parachutes successfully deployed was because of this burn-through; otherwise, they would have failed… an ominous harbinger of what would befall Komarov in April. Clearly, a Cosmos 140-type event would have doomed a human occupant, but the descent module separated successfully, parachuted to Earth and crashed through the ice of the frozen Aral Sea. It was retrieved by divers in 10 m of water and, astonishingly, the results of its mission were deemed “good enough” for Komarov to take the helm of a future flight.

In his autobiography, Alexei Leonov remarked that the Cosmos 140 burn – through had been caused by a flawed design feature which was slightly different to that on a manned Soyuz and admitted that “there was no chance of the fault recurring”. Still, today, it seems ludicrous to have even contemplated a manned mission with such unpromising test results and unforgiving hardware. Political pressure seems to have been the overriding impetus driving Soyuz’ schedule. One Soviet heat shield engineer, Viktor Yevsikov, hinted in 1982 that “some launches were made almost exclusively for propaganda purposes. . . the management knew that the vehicle had not been completely debugged: more time was needed to make it operational, but the Communist Party ordered the launch despite the fact that preliminary launches had revealed faults in the co-ordination, thermal control and parachute systems’’. The situation was so bad, admitted Yevsikov, that Vasili Mishin himself refused to sign the endorsement papers permitting Soyuz 1 to fly. He felt it was unready.

Mishin, despite being an excellent mathematician and fast-thinking engineer, was no Korolev. He had none of his predecessor’s stature or clout and was not renowned for his diplomatic skills. “Lacking the political instincts of, say, a Wernher von Braun or a Sergei Korolev,’’ wrote Asif Siddiqi, “he suffered dearly. Some would argue that so did the Soviet space programme in the coming years.’’ Nonetheless, with little opposition, Mishin was named Chief Designer in May 1966 and, although he quickly asserted himself, his insistence on filling the cosmonaut corps with non­pilot engineers from the OKB-1 design bureau to fly the early Soyuz missions infuriated Nikolai Kamanin. In his diary, the latter fumed that Mishin placed no value in six years’ worth of experience of his command’s training of cosmonauts to fly space missions. Kamanin considered it absurd that Mishin wanted to prepare civilian engineers for Soyuz command positions, with no pilot training, no parachute experience, no medical screening and no centrifuge practice. Eventually, under pressure from Dmitri Ustinov, Mishin was forced in July 1966 to accept pilot- cosmonauts for Soyuz command positions, with OKB-1 engineers filling support roles. It was only the first of many stand-offs between he and Kamanin which would place their relationship at a very low ebb.

Mishin’s desire to fly civilians into space had been shared by Sergei Korolev and, intermittently in the early Sixties, a few OKB-1 engineers had passed preliminary screening, but were never seriously considered by the Soviet Air Force. When eight military cosmonauts began training for the first Soyuz missions in September 1965, Korolev entrusted one of his engineers to explore the possibility of forming a parallel group of civilians. Eleven candidates passed initial tests at the Institute of Biomedical Problems and several months later, on 23 May 1966, Mishin signed an official order to establish the first non-military cosmonaut group. Candidates Sergei Anokhin, Vladimir Bugrov, Gennadi Dolgopolov, Georgi Grechko, Valeri Kubasov, Oleg Makarov, Vladislav Volkov and Alexei Yeliseyev seemed to have little hope of actually flying into space and the nomenclature used to describe them – ‘cosmonaut – testers’ – seemed to support the assumption that they would be of limited use.

Despite his doubts, Kamanin was finally appeased when Grechko, Kubasov and Volkov passed tests at the Air Force’s Central Scientific-Research Aviation Hospital and arrived at the cosmonauts’ training centre, Zvezdny Gorodok, on 5 September. Within two months, another pair, Yeliseyev and Makarov, had also arrived. All five, wrote Siddiqi, ‘‘were accomplished engineers’’, Grechko having worked on fuelling Korolev’s R-7s and Makarov having been involved in Vostok, Voskhod and Soyuz development. Unfortunately, Anokhin, Bugrov and Dolgopolov did not pass the Air Force’s screening and were never considered for positions on the early Soyuz missions.

For the others, however, a seat on a spaceflight seemed only months away. Military pilot Vladimir Komarov had long been pointed at Soyuz 1, owing to his expertise, but Mishin, naturally, wanted two civilian engineers on the three-man Soyuz 2 crew. Nikolai Kamanin opposed this move, feeling that the complexity of the early missions made it inadvisable. A compromise was reached, thanks to the chief of the Communist Party’s Defence Industries Department, Ivan Serbin, who suggested flying an Air Force pilot (Yevgeni Khrunov) and an OKB-1 engineer (Alexei Yeliseyev) alongside Vostok 5 veteran Valeri Bykovsky on Soyuz 2. A few days later, on 21 November 1966, Komarov told a State Commission meeting at Tyuratam that he had been picked to fly Soyuz 1 and that Bykovsky, Khrunov and Yeliseyev would follow aboard Soyuz 2. It was a triumph for the civilians. Yet had Yeliseyev flown as planned on Soyuz 2, he would not only have become the first of Mishin’s civilians to enter space, but would have also been the first of them to die during his descent to Earth…

Over the years, western observers suspected that the Soyuz 1 mission had been pushed to fly prematurely and improperly as a political stunt in advance of the May Day celebrations, since 1967 coincided with the half-century anniversary of the Bolshevik Revolution. Additionally, Leonid Brezhnev was in Karlovy Vary in Czechoslovakia at the time, at a meeting of the Soviet bloc leadership; the propaganda value of a major space success, for him, would be incalculable. In a dispatch to the Washington Star newspaper, Moscow correspondent Edmund Stevens wrote that the space effort under Mishin was less able to resist political pressure than Korolev had been. (It was even suggested that Leonid Smirnov, chairman of the Military-Industrial Commission, had personally told Komarov, still sceptical about Soyuz’ readiness, that the cosmonaut might as well remove all of his military decorations if he refused to fly the mission… )

In the days preceding the manned shot, rumours hinted of a space spectacular to rival Gemini and Apollo: a joint mission involving not one Soyuz, but two, and perhaps featuring rendezvous, docking and even the spacewalking transfer of crew members from one vehicle to the other. Reuters, for example, revealed on 19 April 1967 that such stories were circulating with some excitement in Moscow. Three days later, western journalists in the Soviet capital were told that two spacecraft with five or six cosmonauts would be launched, beginning on 23 April. If all went well with the first mission, it seemed likely that Soyuz 2 would fly at 3:10 Moscow Time the next morning. Komarov would attempt a docking on Soyuz 2’s first or second orbit and the two spacecraft would remain docked for perhaps three days. “There was speculation,” Time magazine told its readers on 5 May, “that the second ship had a restartable engine that would push the joined ships as far out as 50,000 miles.” This was obviously a false assumption, but it does highlight the uncertainty of exactly what the Soviets were up to.

Actually, the joint mission, and specifically the spacewalking transfer of cosmonauts between two spacecraft, had caused concern for months. The hatch in the Soyuz orbital module, for example, was barely 66 cm in diameter, scarcely wide enough for a fully-suited man to get outside and virtually impossible for him to get back inside. (The problems of space suits ‘ballooning’ had already been experienced by Alexei Leonov.) A redesign of the hatch, Mishin realised, would add months to the schedule and the decision was instead taken to modify the suits by moving their oxygen supplies from the cosmonaut’s back to his waist. Enlarged hatches would then be implemented on later missions. Nikolai Kamanin was unimpressed. ‘‘I am personally not fully confident that the whole programme of flight will be completed successfully,’’ he wrote, ‘‘although there are no sufficiently weighty grounds to object to the launch. In all previous flights we believed in success. Today, there is not such confidence in victory. . . This can perhaps be explained by the fact that we are flying without Korolev’s strength and assurances.” It did not bode well for the four men assigned to fly the Soyuz 1/2 joint mission.

Photographs released over the years have shown Komarov training with Bykovsky, Khrunov and Yeliseyev, the latter pair clad in EVA-type suits, confirming that they would have attempted the risky Soyuz-to-Soyuz transfer. Others show Yuri Gagarin, Komarov’s backup, assisting Khrunov with his helmet. In their biography of Gagarin, Jamie Doran and Piers Bizony pointed out that it was Korolev’s death in January 1966 which refocused the First Cosmonaut on somehow getting himself back into space. His renewed self-discipline and vigour in completing an engineering diploma at the Zhukovsky Air Force Academy impressed Nikolai Kamanin sufficiently to assign Gagarin in October 1966 as Komarov’s backup. However, despite his confidence, Kamanin noted in his diary that Gagarin’s importance to the Soviet state made it unlikely he would ever fly again.

Years later, Soviet journalist Yaroslav Golovanov would recall Gagarin’s behaviour in the hours before the Soyuz 1 launch as quite unusual. ‘‘He demanded to be put into the protective space suit,’’ Golovanov was quoted by Doran and Bizony. ‘‘It was already clear that Komarov was perfectly fit to fly, and there were only three or four hours remaining until liftoff time, but he suddenly burst out and started demanding this and that. It was sudden caprice.’’ Venyamin Russayev expressed his belief over the years that Gagarin was trying to elbow his way onto the mission to save Komarov from almost certain death in a botched spacecraft. Others have countered that, since Komarov was not meant to wear a space suit on Soyuz 1, Gagarin’s antics were actually designed to encourage his comrade to take one as an additional safety margin. Alternatively, maybe Gagarin was simply trying to disrupt matters somehow. Whatever the reality, archived pre-launch footage of the cosmonauts from that fateful third week of April 1967 – an unhappy Komarov, a downcast Gagarin and a team of very dejected technicians – show that that the atmosphere at Tyuratam was one of tense pessimism.

Other official images of Komarov arriving at the launch site showed him quite differently: bedecked with flowers… as, indeed, were Bykovsky, Yeliseyev and Khrunov, also in attendance for their own mission a day later. Plans for the flights were still very much in flux. Disagreement flared over whether to dock automatically or manually, with Mishin favouring the former and Komarov expressing confidence that he could guide Soyuz 1 by hand to a linkup from a distance of 200 m. At length, the chair of the State Commission, Kerim Kerimov, supported an automatic approach to 50-70 m, followed by a manual docking, although his judgement was still hotly contested.

Nevertheless, at 3:35 am Moscow Time on 23 April, Soyuz 1 was launched and inserted into a satisfactory orbit of 201-224 km. Within moments of reaching space, the Soviets referred to his mission, by name, as ‘Soyuz 1’, clearly indicating that a ‘Soyuz 2’ would follow soon. Fellow cosmonaut Pavel Popovich told Komarov’s wife, Valentina, that he was in orbit, to which she responded that ‘‘he never tells me when he goes on a business trip!’’ Four and a half hours into the mission, a bulletin announced that the flight was proceeding normally; as, indeed, did another report at 10:00 am. More than 12 hours then elapsed before any more news emerged from the Soviets, and when it did finally come, it was devastating. Not only had there been no Soyuz 2 launch, but, stunningly, Komarov had lost his life during re-entry.

Little information other than the basics were forthcoming in the terse final report. It alluded to Soyuz 1’s ‘‘very difficult and responsible braking stage in the dense layers of the atmosphere’’ and concluded that the ‘‘tangling of the parachute’s cords’’ had caused the spacecraft to fall ‘‘at a high velocity, this being the cause of the death of Colonel Vladimir Komarov’’. Twenty years later, Phillip Clark wrote of ‘‘persistent reports’’ that problems had been experienced during Soyuz 1’s first few hours in orbit. Its left-hand solar array failed to deploy properly, depriving Komarov of more than half (some sources say as much as 75 per cent) of his electricity supply. Soyuz 1 would be forced to run on batteries for a shortened mission of around a day in orbit. The subsequent, unusual, lack of televised images from the cabin and no other reports of in-flight activities lent credence to notions that the flight was in deep trouble.

A backup telemetry antenna also failed, probably triggering intermittent reception, and problems with solar and ionic sensors prevented Komarov from achieving even basic control of his craft’s orientation. (It later became clear that the Sun sensor had actually been contaminated by Soyuz’ thruster exhausts.) Although the antenna failure was a minor annoyance, the solar sensor was more serious, because without it Soyuz 1 could not be properly oriented for rendezvous and docking. During his fifth orbit, the cosmonaut tried to use his periscope and Earth’s horizon to reorient the craft, but found it virtually impossible to do so. The failure of the left-hand solar panel to open had also left Soyuz 1 in an asymmetric configuration, which made attitude control far more difficult. At one point, Komarov even knocked with his boots on the side of the spacecraft, to free a stubborn deployment mechanism for the panel, but without success. By this time, the Soyuz 2 launch – already hampered by heavy rain at Tyuratam, but now exacerbated by the ongoing problems in orbit – had been called off and the focus had shifted instead to ensuring Komarov’s safe return to Earth.

Attempts to bring him home, Clark continued, were planned on the 16th, 17th and 18th orbits, with the first retrofire attempt called off, presumably because the spacecraft could not be properly stabilised. Indeed, Doran and Bizony have reported that, at one stage, Komarov complained with fury: “This devil ship! Nothing I lay my hands on works properly.’’ Unlike the spherical Vostok, the underside of Soyuz’ bell-shaped descent module was distinctly flattened and it had an offset centre of gravity to provide it with some aerodynamic ‘lift’ during re-entry. However, it also required far more precision as it began to enter the atmosphere and, with Soyuz 1’s guidance system out of action, the cosmonaut could not keep it under control. When it began to spin, he attempted to fire his attitude-control thrusters to stabilise the situation, but their close proximity to the navigation sensors meant that he could not accurately align the spacecraft. In desperation, Komarov resorted to using the Moon to work out his alignment.

The first retrofire attempt apparently began at 2:56 am on 24 April, but the problems forced the automatic control system to inhibit it. A decision was made shortly thereafter not to make another attempt on the 17th circuit, but to use that pass over Russia to prepare him for re-entry on the next orbit. Sometime between 3:30-4:00 am, a Japanese station received signals from Soyuz 1 and Tass announced that a routine communications event was being held between mission controllers and Komarov. That ‘event’, according to some, was far from routine. In August 1972, a former National Security Agency analyst, under the pseudonym Winslow Peck (real name Perry Fellwock), reported being on duty at a monitoring station near Istanbul in Turkey on the morning of Komarov’s death. According to Fellwock’s report, the cosmonaut and ground controllers knew that the situation would produce fatal consequences and Komarov even spoke personally to his wife, Valentina, and to a tearful Soviet premier Alexei Kosygin. ‘‘He told [his wife] how to handle their affairs and what to do with the kids,’’ wrote Fellwock. ‘‘It was pretty awful. Towards the last few minutes, he was falling apart. . . ’’

These and other harrowing, though unverified, reports imply that Komarov knew that the problems with Soyuz 1 were insurmountable. Unconfirmed stories over the years hinted that, when he finally began re-entry, he grumbled that ‘‘the parachute is wrong’’ and ‘‘heat is rising in the capsule’’. Evidently, the actual retrofire on his 18th orbit was far from perfect, in light of the asymmetrical shape of the spacecraft and the inability of the attitude-control thrusters to maintain proper orientation. Still, retrofire began at 5:59 am and ran for long enough to ensure entrance into the atmosphere. The Yevpatoriya control station in the Crimea picked up voice communications at 6:12 am, in which Komarov apparently advised them of the results of the retrofire and his loss of attitude, before entering a period of blackout as heated plasma surrounded the spacecraft.

During re-entry, the descent module should have separated from the remainder of the Soyuz – the orbital and instrument sections – about 12 minutes after retrofire. Parachute deployment should have begun 14 minutes later and touchdown some 39 minutes and 27 seconds after retrofire. Komarov’s voice reappeared during re-entry, sometime between 6:18 and 6:20 am, and was described as calm and unhurried, in spite of the 8 G load imposed by what was effectively a steep, ‘ballistic’ descent. Notwithstanding these problems, Soyuz 1 might still have landed safely. Then its parachutes failed.

In his autobiography, fellow cosmonaut Alexei Leonov related being based in the control centre, participating in the recovery effort. He wrote that ‘‘the brake chute deployed as planned and so did the drag chute, but the latter failed to pull the main canopy out of its container. While the reserve chute was then triggered, it became entangled with the cords of the drag chute and also failed to open’’. Indeed, Soyuz 1’s landing point – at 51.13 degrees North latitude and 57.24 degrees East longitude, some 65 km east of the industrial city of Orsk, in the southern Urals – was considerably farther west than normal and has been seen by many analysts as ‘‘consistent with a purely ballistic re-entry. . . and no parachute deployment’’. Locals in the Orsk area, who witnessed the final stages of the descent, confirmed that Soyuz 1’s parachutes were simply turning, not filling properly with air…

Meanwhile, Soviet anti-aircraft radar installations detected the incoming descent module at 6:22 am and predicted its ‘landing’ two minutes later. Elsewhere, listening posts in Turkey are said to have intercepted Komarov’s cries of rage and frustration as he plunged to his death, cursing the engineers and technicians who had launched him in a fault-ridden spacecraft. Whether this really happened will probably never be known with certainty. Travelling at more than 640 km/h, Soyuz 1 hit the ground like a meteorite, killing the cosmonaut instantly and completely flattening the descent module. Solid-fuelled rockets in its base – meant to cushion the touchdown – detonated on impact, causing the remains to burst into flames. The whole landing site was soon engulfed in smoke and the first helicopter pilot on the scene quickly judged that it was a fatal situation. ‘‘But he also knew he was on an open loop with Yevpatoriya and the Ministry of Defence satellite control centre in Moscow,’’ wrote Deke Slayton. ‘‘All he said was ‘the cosmonaut is going to need emergency medical treatment outside the spacecraft’, at which point the lines were cut by somebody in the rescue units.’’

The misleading call for ‘urgent medical attention’ is an intriguing story in itself. Flight surgeons Oleg Bychkov and Viktor Artamoshin, members of the search and rescue group which found Soyuz 1, recounted later that their helicopter touched down 70-100 m from the point of impact. ‘‘Everybody rushed to the capsule,’’ they wrote, ‘‘but only upon reaching it, realised that the pilot would no longer need help. Fire inside the spacecraft was spreading and its bottom completely burned through with streams of molten metal dripping down.’’ The rescue team was equipped with coloured flares to signal the overflying aircraft about the situation on the ground. No code existed to denote the death of the cosmonaut, so they were forced to fire the flare which equated to Komarov needing medical aid. It was this misunderstood message which, tragically, kindled some hope that Vladimir Komarov had survived.

On the ground, the flames were so fierce that portable foam extinguishers proved insufficient and the would-be rescuers began shovelling heaps of dirt onto the capsule. The force of impact had already reduced it from its normal 2 m height to a tangled mess no more than 70 cm tall and it was during the frantic firefighting effort that Soyuz 1 literally collapsed, leaving a pile of charred wreckage and a couple of congealed pools of molten aluminium, topped by the circular entrance hatch. Nearby lay the three parachutes. Komarov’s remains were “excavated” from what was left of his ship at 9:30 am and his death was pronounced as having been caused by multiple injuries to the skull, spinal cord and bones. Later eyewitness reports revealed that his ‘body’ took the form of a ‘lump’, 30 cm wide and 80 cm long, while Venyamin Russayev recounted that a heel bone was the only recognisable fragment left…

By this time, Nikolai Kamanin himself was on the scene and it was he who telephoned Dmitri Ustinov, who in turn contacted Leonid Brezhnev. Five hours later, it was Ustinov who carefully edited Tass’ communique on the subject of Komarov’s death.

A government investigation, headed by V. V. Utkin of the Flight Research Institute of the Aviation Industry, revealed that Soyuz 1’s parachute container had opened at an altitude of 11 km and had become ‘deformed’, squeezing the main canopy and preventing it from opening correctly. Although a small drogue had come out, the main parachute simply could not exit the container, and not just because of the deformation. The drogue was supposed to impart a force of 1,500 kg to pull out the main parachute, whereas it actually required upwards of 2,800 kg, perhaps a result of air pressure in the descent module pushing against the container. Such problems had never arisen in tests, Utkin’s panel found, but attributed them to the abnormal and ‘random’ conditions surrounding the Soyuz 1 descent. Future missions, the panel decreed, would benefit from enlarged and strengthened parachute containers. The failure of the drogue to pull out the main parachute was compounded by its backup canopy. This quickly became entangled with the fluttering drogue, leaving nothing to arrest Komarov’s meteoric fall to Earth.

Unofficially, gross negligence on the part of manufacturing technicians has also been blamed for Komarov’s death. During pre-flight preparations, explained Asif Siddiqi, the Soyuz 1 and 2 spacecraft were coated with thermal protection materials and placed in a high-temperature test chamber. Both were evaluated with their parachute containers in place, but lacking covers. This resulted in the interiors of both containers becoming covered with a polymerised coating, which formed a very rough surface and directly prevented Soyuz 1’s parachute from deploying. ‘‘Clearly,’’ wrote Siddiqi, ‘‘the most chilling implication of this manufacturing oversight was that both Soyuz spacecraft were doomed to failure – that is, if Komarov had not faced any troubles in orbit and the Soyuz 2 launch had gone on as scheduled, all four cosmonauts would have died on return.’’ None of this was mentioned in the official Soyuz 1 accident report.

As the Soviets, like the Americans, dug in for a lengthy period of self-criticism and introspection to make their craft spaceworthy, not another cosmonaut would venture aloft until October 1968. That cosmonaut, Georgi Beregovoi, would establish a new record as the oldest man yet to be launched into orbit, aged 47. He was also one of Yuri Gagarin’s harshest critics – a senior Soviet Air Force officer, Second World War combat veteran and decorated test pilot, albeit unflown in space – who considered the First Cosmonaut to be “an upstart’’ and a bit-of-a-lad who was “too young to be a proper Hero of the Soviet Union’’. Their relationship in the months before Komarov’s death grew so stormy that Gagarin even shouted that Beregovoi would never fly in space.

Seven months after Gagarin’s untimely death in an aircraft crash, Beregovoi finally got his chance. It was he who would lay the ghost of Vladimir Komarov to rest and nurse Soyuz through its first successful manned mission.

‘‘I had pointed Frank Borman at one of the Gemini long-duration missions from the very begininng,’’ Deke Slayton wrote in his autobiography, ‘‘because of his tenacity.” That tenacity, some argued, had also led to his removal from the right – hand pilot’s seat, alongside Gus Grissom, on the original Gemini V. It has been speculated that the two men’s strong personalities might have made them incompatible as a commander-pilot duo and the no-nonsense, decisive Borman was instead directed to lead Gemini VII. Some astronauts regarded him as obnoxious and Gene Cernan labelled him a “tight-assed son-of-a-bitch’’, but none questioned his abilities or impeccable leadership skills. Indeed, he remains one of only five American astronauts to have commanded a crew on his very first mission. One day, in the not too distant future after Gemini VII, his talent and credentials would also lead him to command the first human expedition to the Moon.

Frank Frederick Borman II was born in Gary, Indiana, on 14 March 1928. As a child, he suffered from numerous sinus problems, caused by the cold and damp weather, so his father moved the family to the better climate of Tucson, Arizona, which became Borman’s hometown. Like many future astronauts, he could trace his fascination with aviation from an early age and began flying at the age of 15. From Tucson High School, Borman studied for a bachelor’s degree at the Military Academy in West Point, followed by a master’s in aeronautical engineering from the California Institute of Technology.

After graduation from West Point in 1950, ranking eighth in his class, he entered the Air Force, serving as a fighter pilot in the Philippines and later as an instructor attached to various squadrons across the United States. During one practice dive­bombing run, he ruptured an eardrum, leading him to fear that he may never fly again. However, Borman recovered. Before coming to NASA in September 1962, he also graduated from the Air Force’s Aerospace Pilot School as an experimental test flier and served for a time as an assistant professor of thermodynamics and fluid dynamics at West Point. At the time of his selection, he had more experience in jet aircraft – some 3,600 hours – than any of the others in the New Nine.

Clearly, even among the Nine, Borman stood out. During the selection process, his absolute devotion to the West Point military code of Duty-Honour-Country and his unwavering commitment to whatever mission he was assigned led some psychologists to shake their heads in disbelief. Surely nobody could be that uncomplicated, they thought. Yet that was Borman. Like Gus Grissom, he did not dabble in small talk and, in true military fashion, made whatever decisions needed to be made, stuck by them and told his crew afterwards.

In many ways, James Arthur Lovell Jr – whom Pete Conrad had nicknamed ‘Shaky’ for his bubbling stores of nervous energy – was virtually Borman’s twin. Both were born within two weeks of each other, both held equivalent ranks within different services, both were fair-haired and blue-eyed and both were selected as astronaut candidates together. Lovell was born on 25 March 1928 in Cleveland, Ohio and his fascination with rockets, like Borman’s with aviation, manifested itself at a young age. In his book on the Apollo 13 mission, co-authored with Jeffrey Kluger, Lovell recounted sheepishly visiting a chemical supplier in Chicago one day in the spring of 1945 to buy chemicals with which he and two school friends could build a rocket for their science project. Despite the boys’ admonitions over wanting to create a liquid-fuelled device, like those of Robert Goddard and Hermann Oberth,

their teacher guided them instead towards a solid-propelled one, loaded with potassium nitrate, sulphur and charcoal. Days later, after packing the gunpowder ingredients into a shell of cardboard tubes, a wooden nosecone and a set of fins, the boys took their rocket into a field, lit the fuse and ran like hell.

“Crouching with his friends,” Lovell wrote in third-person narrative about his exploits, “he watched agape as the rocket he had just ignited smouldered for an instant, hissed promisingly and, to the astonishment of the three boys, leapt from the ground. Trailing smoke, it zigzagged into the air, climbing about 80 feet before it wobbled ominously, took a sharp and surprising turn, and with a loud crack exploded in a splendid suicide.”

Lovell’s interest in the workings and possibilities of such projectiles eclipsed that of his two friends, who regarded this as little more than a lark, but his family situation made it unrealistic to hope that a career in rocketry was within his grasp. The Lovells had moved to Milwaukee, Wisconsin, when he was a young boy and his father’s death in a 1940 car accident placed enormous pressure on his mother to make ends meet. The military and, in particular, the Navy, seemed an attractive alternative. (Lovell’s uncle, in fact, had been one of world’s earliest naval aviators during the First World War.) He was accepted, eventually, into the Navy, which offered to pay for two years of an undergraduate degree, provide initial flight

training and six months of active sea duty. Lovell jumped at the chance and, within months, was registered as an engineering student at the University of Wisconsin at Madison. He would complete his studies in 1952, receiving a bachelor’s degree from the Naval Academy at Annapolis.

Whilst at the academy, he met Marilyn Gerlach, whom he married barely three hours after his graduation ceremony… and who had typed up his carefully – prepared thesis on liquid-fuelled rocketry. Flight training consumed much of the next two years, after which Lovell was attached to Composite Squadron Three, based in San Francisco, whose speciality included nighttime takeoffs and landings on aircraft carriers at the height of the Korean conflict. Several months later, he was flying F-2H Banshee jets from the Shangri-La aircraft carrier over the Sea of Japan, routinely swooping in to land on its deck. On one occasion, however, a routine flight went seriously wrong. Moreover, the flight was his first mission in darkness.

The only means of determining where the carrier was at night, Lovell wrote, was a beamed, 518-kilocycle signal from the Shangri-La, which allowed the Banshee’s automatic direction finders to guide him home. However, poor weather forced the ship to cancel the mission of Lovell, his teammates Bill Knutson and Daren Hillery and their group leader Dan Klinger; in fact, Klinger had not even left the deck of the Shangri-La when the flight was terminated. Unfortunately for Lovell, his direction finder had picked up the signal of a tracking station on the Japanese coast – which also happened to be transmitting at 518 kilocycles – and, far from guiding him back to the Shangri-La, was actually taking him further away. Around him, he saw nothing but a “bowl of blackness’’.

Perhaps the homing frequencies had changed, Lovell thought. At once, he turned to the list of frequencies on his kneeboard, but upon switching on his small, jury – rigged reading light, “there was a brilliant flicker – the unmistakable sign of an overloaded circuit shorting itself out – and instantly, every bulb on the instrument panel and in the cockpit went dead’’. His options seemed dire: ask the Shangri-La to switch its lights on, which was hardly advisable and would prove hugely embarrassing, or ditch in the icy sea. Then, in a story repeated by Tom Hanks, who played Lovell in the 1995 movie ‘Apollo 13’, he saw a faint greenish glow, like a vast ‘carpet’, stretching out below and ahead of him. It was the phosphorescent algae churned up in the Shangri-La’s wake and it guided him back to the company of his two wingmen, Knutson and Hillery, and a safe, though hard, landing which he later described as ‘‘a spine-compressing thud’’.

For his efforts, the sweat-drenched Lovell was given a small bottle of brandy, downed in a single gulp, and the opportunity to fly his next nocturnal mission. . . the very next night. This time, thankfully, his automatic direction finder behaved flawlessly. Eventually, he accumulated no fewer than 107 carrier landings and became an instructor in the FJ-4 Fury, F-8U Crusader and F-3H Demon jets, before moving to the Navy’s Test Pilot School at Patuxent River. He graduated first in his class, ahead of Wally Schirra and Pete Conrad. Less than two years later, in early 1959, he was one of 110 military test pilots ordered to attend a classified briefing in Washington, DC. Like Conrad, he would be turned down for Project Mercury, but secured admission into the exalted ranks of NASA’s astronaut corps, together with Frank Borman, in September 1962.
