The Apollo 17 landing in the Taurus-Littrow Valley was the last Apollo mission, with Apollo 18, 19, and 20 terminated due to budget cuts. As of this writing, Apollo 17 proved to be the last time man set foot on the Moon. Apollo 17 was the final J-type mission, distinguished from the previous G – and H-series missions by expanded and improved hardware, a larger instrumentation package, and extended exploration and sampling range using the Lunar Roving Vehicle, or LRV. The pri­mary objectives of Apollo 17 were threefold:

• Conduct geological observations and collect samples of the Taurus-Littrow region for data of the specific area. The Apollo 17 mission collected Taurus – Littrow information for comparison with geologic data from the previous Apollo mission regions. This objective was aided with the extended range provided by the LRV. The LRV carried onboard two experiments, the Lunar Traverse Gravimeter (LTG) and the Surface Electrical Properties (SEP) experiment.

• Deploy and activate a new version of the Apollo Lunar Surface Experiments Package, or ALSEP, that included five experiments not previously deployed by the earlier Apollo missions. The ALSEP included a heat flow experiment; lunar seismic profiling experiment (LSPE); lunar surface gravimeter (LSG); lunar atmospheric composition experiment (LACE); and lunar ejecta and meteorites (LEAM).

• Conduct lunar orbiting experiments from Apollo 17’s Service Module, including a lunar sounder, infrared scanning radiometer, and far-ultraviolet spectrometer.

Apollo 17 was the first and only Apollo mission that included a scientist as part of the crew. Geologist Jack Schmitt served as the LM pilot, with veteran Astronaut Gene Cernan serving as the Apollo 17 Commander and flying the LM. Both Gene Cernan and CM pilot Ron Evans received extensive training in geology and lunar science, with Ron Evans concentrating on visual recognition and observation of geological features from long distance.

The original crew assignment was Gene Cernan, Ron Evans, and Joe Engle, a former X-15 pilot credited with 16 X-15 flights. Three of Engle’s X-15 flights exceeded the altitude of 50 miles which earned him astronaut wings prior to his joining Apollo. The normal NASA practice was to have the backup crew of a mis­sion be the primary crew three missions later. Cernan, Evans, and Engle served as the backup crew for Apollo 14, and as such were the primary crew for Apollo 17. Jack Schmitt was originally scheduled for Apollo 18 as the LM pilot. With the cancellation of Apollo 18, 19, and 20, there was pressure to include a scientist on Apollo 17. Thus, Schmitt replaced Engle as the LM pilot for Apollo 17. Prior to the Apollo 17 mission, Jack Schmitt’s claim to fame was cleaning up a transmission verbal faux pas of Astronaut Tom Stafford on Apollo 10 by rephrasing Stafford’s description of a crater as “bigger than Schmitt!”.

Joe Engle would never fly to the Moon, but he did fly as commander on Space Shuttle STS-2 with Shuttle pilot and future NASA Administrator Richard Truly, and as mission commander of STS-51-1. Engle is the only astronaut to fly both the X-15 and the Space Shuttle winged spacecraft into space, and to control and land the Space Shuttle manually.

The LM Challenger landed within 200 m from the planned landing coordinates. Three EVA’s were conducted, with the first EVA tasks including: the deployment of the ALSEP, deployment of the first set of geophones and explosive charges as part of the LSPE, and conducting a cosmic ray experiment using the Cosmic Ray Detector (CRD). During the second EVA, Astronauts Cernan and Schmitt used the LRV to collect core samples, dig trenches, and traverse from Nansen Crater, Lara Crater and various points along the way. These stops were made along the way to collect data from the Lunar Traverse Gravimeter (LTG) and the Surface Electrical Properties (SEP) experiment, and deploy additional LSPE geophones and explosive charges. The third EVA, additional sampling stops and traverse gravimeter mea­surements were made. Additional geophones and explosive charges for the LSPE were deployed, and the EVA ended with the retrieval of the neutron flux probe from the deep drill core hole. Each EVA lasted over 7 hours.

The Taurus-Littrow Valley is fairly easy to identify with a telescope. The site is at the southeastern rim of the Sea of Serenity and intersects the Sea of Tranquility.

The landing site selected for Apollo 17 was in the Taurus-Littrow Valley on the southeastern rim of Sea of Serenity. Obtaining samples that would determine how this region of the Moon formed particularly interested lunar scientists in this landing site. The two primary objectives were obtaining samples of highland material that were older than the Imbrium impact and investigating the possibility of young, explosive volcanism in this region. Taurus-Littrow was one of several sites consid­ered, along with the Tycho crater, Copernicus crater, and the Tsiolkovsky crater on the far side of the Moon. The Tycho crater was considered too dangerous because of the roughness of the terrain. Copernicus crater was a low priority site. A far side mission to Tsiolkovsky crater created significant communications problems, with the necessity of placing a constellation of expensive communication relay satellites in orbit around the Moon to provide continuous communications with Mission Control and the command module. The Taurus-Littrow site was selected with the anticipa­tion of sampling ancient highland material and young volcanic material in the same landing site. The Taurus-Littrow site also provided the sampling of Tycho ejecta, and geologists suspected some of the craters in the area could be volcanic vents.

As an observer increases magnification, under steady seeing, the landing area can be seen to have both lighter or darker material. The geologists referred to this mate­rial as light mantle and dark mantle material, stemming from suspected lava flows.

The chosen landing site is in an area between two geological massifs, or moun­tain masses, where observational evidence showed dark material from either land­slides or pyroclastic deposits. This dark mantle material is covered with small craters, which scientists at the time postulated either volcanic or meteoric in origin. The results of the Apollo 17 geological studies suggest that approximately 100 mil­lion years ago, lava seeped to the Moon surface and flooded and pooled to form the Taurus-Littrow area and Sea of Serenity. The lava flows apparently were accompa­nied by fire fountains, which formed both orange and dark-colored beads in the soil. Several samples of lunar soil from Taurus-Littrow contained orange glass beads, causing the samples to have an orange hue. Fire fountains also accounts for the dark glassy material collected at the Taurus-Littrow landing site.

Figure 9.6 is one of the LRO’s clearest photos of an Apollo landing, with the Challenger’s descent stage clearly visible. Since the Moon has no weather or envi­ronmental conditions that can inflict weathering on the soil, the tracks of the lunar rover and the footprints of the astronauts can be easily seen. Unfortunately, this cannot be seen with backyard telescopes. The LRO photographs are taken at an altitude of 50 miles above the lunar surface.

Also visible in this picture is a cluster of craters. It has been determined from the Apollo 17 mission, that much of the main crater cluster was the secondary impact result of the massive Tycho impact less than 95 million years ago. Most of these secondary impact craters were the result of eject spreading out downrange from the Tycho crater. The downrange pattern formed points directed at Tycho. The lighter colored material originated from landslides caused by the secondary ejecta from Tycho hitting the Taurus-Littrow massifs.

The Apollo 17 LRV carried onboard two experiments to obtain data during the lunar traverses. One experiment, the Lunar Traverse Gravimeter (LTG) measured the value of the Moon’s gravity around the Taurus-Littrow area. The LTG, by mea­suring the minute variations of gravity, provided data to determine the shape and depth of the bedrock. At each stop, the astronauts read the LTG readings over voice communications link to Mission Control. Twenty-six measurements were success­fully taken during the first, second and third traverses. This was fortunate, since the similar Lunar Surface Gravimeter (LSG) experiment, part of the ALSEP, failed to function due to a design error.

The other experiment, known as the Surface Electrical Properties (SEP) experi­ment looked for layering in Taurus-Littrow soil by transmitting radio waves into the Moon surface, using interferometry from the radio wave returns, and identifying the layers of the lunar soil. Readings were taken at each stop, with the SEP transmitter set up each time a distance away from the LRV, and the receiver mounted on the front of the LRV receiving the reflected radio signal.

An interesting and historically humorous footnote to the Apollo 17 mission was mankind’s first car accident and car repair on another world. Figure 9.12 shows the makeshift repair on the right rear fender of the lunar rover. Apparently during the first EVA, Gene Cernan brushed against the Lunar Rover, and a hammer in his spacesuit shin pocket caught the LRV’s right rear fender and knocked off half of it. As a result of the broken fender, the rover kicked up a dust plume while moving. The dark dust covered the astronauts, which absorbed the heat from the sunlight and could potentially cause overheating problems for Cernan and Schmitt. The abrasive moon dust also could cause scratching of the astronauts’ visors, and affect the operation of the various latches, hinges, and joints of the LRV. At the beginning of EVA 2, using the universal fix-all duct tape, Cernan was able to re-attach the fender piece after two tries. The taped on fender lasted for over four of the 7 hours EVA 2. However, the duct tape lost some of its stickiness because of the ubiquitous moon dust. For the rest of EVA 2, time was lost as the astronauts frequently used a moon dust brush to clean off the LRV, equipment and themselves. During the break between EVA’s, Cernan and Schmitt fashioned a makeshift fender out of four lami­nated maps and duct tape while inside the relatively cleaner LM. The tape worked better this time, and the new fender was attached by using clamps from the optical alignment telescope lamp. The makeshift fender lasted for the all of EVA 3.

Boulders of various sizes are scattered throughout the Taurus-Littrow valley. At the ALSEP area, deployed west of the Apollo 17 landing site, the boulders aver­aged about 4 m in size and were found to be more numerous than in other areas of the valley. Figure 9.13 illustrates the large rock where one of the LSPE geophones was placed.

The LSPE included explosive charges that were placed at distances away from the geophones, which when activated, sent shock waves through the lunar soil. A total of eight charges were deployed at distances of between 100 m and 3.5 km from the LSPE at the ALSEP site. The charges were detonated after the astronauts left the surface. The direct shock waves data from the geophones were compared with delayed waves from the detonations to determine the depth of the rock bed beneath the soil.

In light of the near-disaster of Apollo 13 due to an explosion, the safety of the LSPE explosive charges was a priority for the Apollo 17 mission. To assure safety from accidental or inadvertent detonation, the design of the explosive charges needed three safety rings pulled during deployment of the charge to enable three separate subsystems to activate simultaneously. One safety ring activated a timer

that after 90 hours allowed the explosive to be detonated. The second safety ring released the physical barrier that separated the detonator from the explosive charge. The third safety ring activated the battery that provided power to the receiver and firing circuitry for one minute. With the three rings pulled, three independent actions were needed to cause the explosion: the battery timer had to activate to allow power to the firing mechanisms, the sliding physical barrier that separated the detonator from the explosives had to slide into firing position, and a radio signal from NASA on Earth had to be sent to detonate. If the activation radio signal was not transmitted and received within the one minute time window, the device would move the sliding barrier back into the safe position. The explosives charges could not be activated until after 90 hours, well past the time for liftoff of the LM ascent module for its rendezvous with the command module.

The astronauts used a number of devices to take lunar surface samples. Figure 9.15 photo shows Jack Schmitt taking a drive tube sample. These 18-in. drive tubes were either pushed into or driven into the lunar surface to collect a short core sample. Two or three drive tubes could be joined together to create a longer, depth core sample. The depth of the core sample was often determined by the den­sity of the soil. Softer soil enabled the astronauts to physically sample greater depths, while hard dense soils limited the sample size.

The gnomon device was used to provide a physical scale and to color calibrate photos of lunar terrain and samples. One of the difficulties encountered during the Apollo missions was the underestimation of size and distances by the astronauts. The gnomon device provided a reference for determining physical scale. At one point, from his voice transcription at 140:58:51 and his journal notes of the Second EVA second traverse to Geology Station 2, Jack Schmitt used his own shadow as a ruler. His mission notes acknowledges that “everyone underestimates distance on the Moon”. He would call to mission control to check his shadow length from the television image uplinked from the LRV camera to give an estimate of scale. Even mission commander Cernan admitted misjudging distance on the Moon.

One of the discoveries made during Apollo 17 was uncovering orange soil dur­ing EVA 2. None of the previous Apollo missions ever uncovered this orange-hue soil. The orange soil was first identified by Jack Schmitt on the fourth stop of the second traverse. It pays to have a scientist on the mission!

A magnified view of the spheres and fragments in the “orange” soil which was brought back from the Taurus-Littrow landing site by the Apollo 17 crewmen may be seen In Fig. 9.17. Scientist-astronaut Harrison H. “Jack” Schmitt discovered the “orange” soil at Shorty Crater during the second Apollo 17 lunar surface extrave­hicular activity (EVA). The orange and dark glass beads provided clear evidence of volcanic fire fountains to geologists.

At the end of the third and final traverse, the 2-m long probe for the Lunar Neutron Probe Experiment (LNPE) was retrieved and deactivated at the end of the third EVA after 49 hours of exposure. The LNPE was designed to obtain data on neutron capture rates in the lunar regolith as a function of depth. The LNPE was an outgrowth from the analyses conducted of lunar samples returned from the Apollo 11 mission. In an effort by scientists to understand the processes that created the lunar soil, early studies indicated that neutron capture of certain isotopes of samar­ium and gadolinium were involved. The experiment was to gather data that would enable scientists to estimate the age of the lunar soil. The LNPE was deployed northwest of the lunar module in the hole from the deep drill core. Figure 9.18 shows the gold-colored Mylar transport bag and the treadle used for recovering the deep drill core.

The last view of the LM Challenger descent stage taken by the Apollo 17 remote video camera is shown in Fig. 9.19. A little known fact about the televised liftoff of Challenger from the Moon’s surface is that the television camera was manually controlled from Mission Control. The NASA controller manually panned the remote controlled camera 2 seconds ahead of the LM launch to compensate for the delay time of the transmission to the Moon. Millions of television viewers on Earth were treated to a live broadcast of the LM liftoff because of this carefully planned and executed action.

The television broadcasted launch of the LM Challenger culminated the evolu­tion of Apollo television cameras. The lunar-surface images provided by the cam­eras used on Apollo 15, 16, and 17 were of much higher quality than those used in the earlier Apollo missions. The Apollo television camera used on Apollo 11 was of poor quality, producing blobby low resolution black-and white images. The color cameras used during the Apollo 12 and 14 missions were too light sensitive, with the Apollo 12 astronauts burning out the video tube by pointing it at a reflected surface of the LM. Apollo 14 television images showed Astronauts Alan Shepard and Edgar Mitchell as white blobs most of the time. By the J-missions, a high quality color camera had been designed, implemented, and space and lunar qualified for use.

After the LM Challenger ascent stage rendezvoused with the CM America, the Challenger ascent stage was sent crashing into the Moon, with the ALSEP geo­phones left behind by Apollo 12, 14, 15, 16, and 17 recording the impact. NASA reported the ascent stage impacted the Moon at coordinates 19.96 N, 30.50E at 1:50 EST on 15 Dec 1972.

The spent Saturn IVB third stage for Apollo 17 impacted the lunar surface at 4.21S latitude, 12.31 W longitude at 3:32:42 pm EST on 10 Dec 1972.

As of this writing, Apollo 17 has proved to be the last time man has set foot on the Moon.

The longest Apollo lunar mission was Apollo 17, which lasted 12 days. The Apollo astronauts dined on freeze dried foods that were rehydrated with water to make their meals. The food was not spectacular as cuisine, but provided the necessary sustenance for the length of the mission.

Astronauts serving on the ISS, with periodic supply replenishment are aboard for months on end. Food technology for ISS personnel has been improved since the Apollo days. The ISS crews are treated to a wide variety of foods from several cuisines.

The major problem of a Mars mission is carrying enough food consumables to last the length of the mission. NASA has chefs planning and developing a cuisine that astronauts can eat that is varied, tasty, nutritious, and has a shelf life for the Mars expedition that may last years. But a spacecraft can carry only so much. In all likeli­hood, the Mars mission crew may have to use hydroponics to grow fresh vegetables such as lettuce, tomatoes, onions, garlic, peppers, cabbage and other foods in space.

Space food cannot be crumby (pun intended). Not only should it taste good and have good texture, it must keep the amount of crumbs to a minimum, since crumbs float, migrate, and contaminate equipment. Food currently chosen for space is selected for minimal crumbs, and ability to withstand mold and bacteria. In addition, under microgravity conditions, the astronaut’s sense of smell is dulled in space when the fluids in their bodies redistribute as a result of lowered gravity, causing nasal congestion. With smell as a major aspect of taste, and the stuffed up nose of an astronaut, space food tends to be more spicy. A variety of sauces like hot sauce, sweet and sour, sriracha hot sauce, barbecue sauce (Carolina-style? Kansas City – style? Texas-style?), and liquid salt solution (salt grains are like crumbs), can be provided for use to season and spice up most anything. The texture of food is a major aspect of Earthbound cuisine, with foods having a crisp texture, a crunchy texture, or a smooth and creamy texture. Achieving this wide range of food textures in space is difficult to achieve when food comes dehydrated in plastic pouches, and water is added to the pouches for rehydration, and the pouches are reheated as required.

The Moon is an easy and bright target for the beginning, casual, and serious back­yard observer. Even with the unaided eye, one can identify the major Seas as the large smooth grey areas. A good pair of 7 x 35 or 7 x 50 binoculars can resolve some of the major craters and large light and dark regions on the Moon’s surface. But it’s not until the observer starts using a telescope that the “OH WOW!” factor comes into play. “OH WOW” is the exclamation that issues from your mouth when you look through the eyepiece of the telescope at the Moon for the first time. Telescopes with apertures beginning at 60 mm and larger can produce very satisfying images of craters, mountain ranges, mares and lunar domes. And in the case of the subject of this book, a good telescope can help the reader to zoom-in on the Apollo landing sites and appreciate NASA’s great successes.

The reader needs to understand that, depending on the type of telescope being used, the orientation of the image may either be correct or mirrored. This can pose a problem when using Moon maps, or even the images presented in this book. The short-hand guidance is as follows: if the reader is using a Newtonian reflector, don’t worry. If using a refractor or other design, up will be up, down will be down, but left will be right, and right will be left. Don’t worry, you’ll get used to it.

Despite the sophistication and technology that is possessed by today’s backyard astronomer, the reader is reminded that although the Apollo landings sites can be identified, there is no hope to see the remaining Apollo relics left on the Moon. The smallest object that can be seen from an earthbound telescope is a crater the size of the Rose Bowl or Wembley Stadium. The largest Apollo object left on the Moon is the descent stage of the lunar lander, roughly the equivalent of two U-Haul trucks parked side-by-side.

The Ranger Program was NASA’s first step in achieving President Kennedy’s goal of landing a man on the Moon and returning him safely by the end of the 1960s. This long forgotten lunar probe program was initially a source of embarrassment to NASA and the nation, but eventually achieved its goals and paved the way for the Surveyor Program, followed then by the Apollo triumphs. The Ranger spacecraft mission evolved into a simple task: to take images of the lunar surface and return those images to Earth by a telemetry link until the Ranger spacecraft smashed into the Moon.

In the scope of this book, consider visually locating the Ranger sites with a telescope as extra credit. LRO photos have located the Ranger impact sites with difficulty. Fortunately, the Apollo 12 landing site is not only within walking dis­tance of Surveyor 3, but is also within the general area of the Ranger 7 impact zone. Apollo 11 also landed in the general vicinity of Ranger 8. To the backyard observer, basically locating Apollo 11 and Apollo 12 also encompasses the Ranger 7 and Ranger 8 impact zones. To locate the Ranger 9 impact site, first locate the major crater Ptolemy. The crater just south of Ptolemy is the crater Alphonsus, and Ranger 9 impacted just slightly north and east of the central peak within the crater.

The Ranger program was a series of unmanned lunar missions by NASA in the early 1960s whose design goal was to obtain the first close-up images of the lunar surface. The development of the basic Ranger spacecraft system began in 1959. The original concept for Ranger included a gamma ray spectrometer, radar altimeter, television imaging system, and a soft landing seismometer. These scientific equipment should sound familiar as parts of the eventual Apollo sci­entific equipment suites. The first six Ranger missions were complete failures, as NASA went through a learning process for developing space capable vehi­cles, space navigation, and launch technology and procedures. Ranger 1 and 2 were launch failures, and Ranger 3 and 5 totally missed the Moon. Ranger 4 impacted the Moon but experienced electronic systems failure. Ranger 6 impacted the Moon, but its cameras failed to function. At one point, the program was called "shoot and hope". After two congressionally mandated reorganiza­tions of NASA and JPL, the Ranger program was stripped of much of its scien­tific equipment and simplified to its final kamikaze space camera configuration. Ranger 7 successfully returned images in July 1964, followed by two more successful missions.

The Ranger spacecraft had three different configurations.

• Block I, consisting of Ranger 1 and 2, were test missions. They were launched in 1961 for engineering development, and were not targeted for the Moon. The Ranger 1 spacecraft was designed to go into an Earth parking orbit and then into an extended elliptical Earth orbit to test systems and strategies for future lunar missions. Ranger 1 was launched into the Earth parking orbit as planned, but the Agena B booster stage failed to restart to put it into the higher trajectory, so when Ranger 1 separated from the Agena stage it went into a low Earth orbit and began tumbling. The satellite re-entered Earth’s atmosphere on August 30, 1961. The Ranger 2 followed a similar fate, and was launched into a low earth parking orbit, but an inoperative roll gyro prevented the Agena booster stage restart. As with its predecessor, Ranger 2 could not be put into its planned deep-space tra­jectory, and was stranded in low earth orbit upon separation from the Agena stage. The orbit decayed and the spacecraft reentered Earth’s atmosphere on November 20, 1961.

• Block II missions comprising of Ranger 3, 4, and 5, were launched during 1962 to achieve rough lunar landings, obtain science data, and test approach television camera operations. These Ranger spacecraft experienced satisfactory vehicle performance, but Ranger 3 missed the Moon by approximately 23,000 miles and Ranger 5 missed the Moon by about 450 miles. Ranger 4 suffered electronics problems that caused the solar panels to not open. Ranger 4 battery power failed after 10 hours and the probe was unable to perform mid-course corrections or activate its cameras. Ranger 4 impacted the Moon on the far side.

• Block III Missions were the Ranger 6, 7, 8, and 9 which used the experience of the earlier Ranger missions to achieve success in 1964 and 1965. NASA learned its lessons on navigating to the Moon and made technology modifications to enable transmission of high-resolution photographs of the lunar surface during the final minutes of flight. Ranger 6 performed satisfactorily en route to the Moon, but the camera failed to operate before lunar impact. Success finally came with Ranger 7, 8, and 9, as those missions fulfilled NASA objectives and provided more than 17,000 photographs at resolutions higher than ever achieved. The Ranger 7 and 8 missions provided coverage of the two types of mare terrain that included the area of the eventual Apollo 11 landing site. Ranger 9 provided coverage of the highland region, impacting in the large central highland crater Alphonsus.

The Ranger photographs provided valuable photographic information for future landing site selection for Surveyor and Apollo missions, and provided surface detail unavailable from Earth-based observations. Each Ranger space­craft had 6 cameras on board. The basic cameras were the same with each camera set up for different exposure times, fields of view, lenses, and scan rates. The camera system was divided into two channels, P for partial and F for full, with each channel design having with independent power supplies, timers, and transmitters.

• The F-channel had 2 cameras: the wide-angle A-camera and the narrow angle B-camera. The final F-channel image was taken between 2.5 and 5 seconds before impact at an altitude of approximately 10,000 feet.

• The P-channel had four cameras: P1 and P2 (narrow angle) and P3 and P4 (wide angle). The last P-channel image was taken between 0.2 and 0.4 second before impact at an altitude of approximately 2,000 feet.

The images provided better resolution than was available from Earth based views by a factor of 1000. The smallest crater that earthbound telescopes could achieve was about the size of a large NFL or major college football stadium, while the images produced by the Ranger cameras showed from pickup truck sized cra­ters down to the 1 feet sized features in Ranger 9 photos. These high resolution images showed Apollo mission planners that finding a smooth landing site was not going to be easy.

To the post World War 2 generation, the Apollo Program represented the hopes and dreams of a bright future and great adventure that was tantalizingly within reach. But the main driver for the race to the Moon was international politics. Created during the height of the Cold War, the rivalry between the two great superpowers, the United States and the U. S.S. R,. provided the impetus for the push into space, culminating in the success of the Apollo Program. The technical challenges were great, but the basis of science supported the idea of landing on the Moon. The technical groundwork of physics, chemistry, and engineering had been laid decades before, and the national focus and challenge of accomplishing a manned lunar mis­sion within a decade provided the necessary energy, commitment, and funding to achieve the goal.

The generations following the Apollo triumphs have lost their way in space. The goals of space travel have become muddled. There is no superpower rivalry that is driving nations to race into space and achieve the goal of landing on Mars. There is no international or national imperative that is pressuring mankind to go to Mars, other than curiosity and the need to explore. The society of the common man has lost sight of the benefits attained by striving towards a common, far reaching goal. The focus on immediate financial accountability has fogged mankind’s vision of the future.

A manned mission to Mars benefits man’s need for exploration, knowledge, and adventure. On the practical side, a program to launch a manned mission to Mars, or even a return to the Moon for potential colonization, represents an opportunity for job creation. New jobs are created from programs directly supporting the space effort to spinoff industries that apply new technologies which provide beneficial products and services. A forward looking approach to space will benefit better edu­cation for the populace, more employment, and better and more meaningful jobs.

Rose colored glasses? Maybe. But the evidence shows the benefits of space – related research and development in a trickle down transfer to every day use.

Every year, NASA publishes a book entitled Spinoff, which highlights products and industries created as off-shoots from space technology. Examples from a recent issue of Spinoff listed the following recent NASA-derived technologies transferred to everyday use:

• Spacesuits incorporating sun-blocking fabric have been adapted to clothing offering protection to ordinary beach goers and people with light sensitivities.

• Gravity-loading technology designed to help astronauts exercise in space have been incorporated into anti-gravity treadmills for rehabilitating after surgery.

• A device NASA invented to study cell growth in simulated weightlessness has been applied to medical research into treatments for heart disease, diabetes, and cirrhosis.

• A star mapping algorithm developed for the Hubble telescope has been adapted to identify unique migrational patterns of endangered species.

• NASA research and development into materials and manufacturing techniques are bringing carbon nanotubes into greater use in everyday applications, such as nanofiber filters to eliminate contaminants.

• Thermal insulation technologies developed for isolating the cryogenic tempera­tures of Saturn V and Space Shuttle fuel tanks have been transferred to applica­tions in the home, resulting in thermal insulation strips that easily apply to wall studs, providing an affordable and environmentally friendly boost to a home’s insulation factor.

These are just a handful of thousands of products derived from the research and development of the space programs such as Apollo, the Space Shuttle, and the ISS. Many new innovations and breakthroughs in technology will result from a focused effort to land a manned mission on Mars. And the public ultimately benefits from these discoveries and innovations in everyday life.
