The Future of Man, Moon, and Mars
Mankind’s return to the Moon seems inevitable. Countries such as Japan, India and China have successfully launched unmanned probes and rovers to the Moon. NASA has been planning a return to the Moon for years. Although challenging, the success of the Apollo program serves as a reminder that the Moon is achievable.
Mars is a greater challenge. The risks are many and some of the questions of extended spaceflight have not been answered. If a breakthrough propulsion system could be developed that would shorten a mission to Mars to be equivalent in length to a lunar mission, say a week to 10 days, many of the difficulties of going to Mars would go away. New technologies, such as the VASIMR ion drive, offer hope by shortening the trip to Mars to 39 days.
Like the Moon landings of Apollo, a manned mission to Mars will have an indelible impact on the future of humankind.
