SpaceWorks is a private company working with NASA to create "human stasis" on spacecraft. Not far off from the depictions shown in famous science fiction films like '2001: A Space Odyssey,' SpaceWorks' human stasis would put astronauts into a type of controlled coma to help them cope with the massive amounts of time that are a necessity of space travel.
Space travel poses a wealth of complex problems, and, aside from the mechanical problems of how to get a rocket into space, engineers are also faced with transporting incredibly delicate cargo: people. While humans can be tough, the monotonous months that people would face on even a mission to nearby Mars would be psychologically challenging for anyone.
SpaceWork's human stasis system would be similar to therapeutic hypothermia, a technique already used in medicine to help people heal after traumatic injuries.
