Evolution of Life Support from Apollo, Shuttle, and ISS to the Vision for the Moon and Mars 2006-01-2013

The Environmental Control and Life Support (ECLS) requirements to reach the International Space Station (ISS), the Moon, and Mars as part of the Vision for Space Exploration (VSE) are similar to the earlier ECLS requirements for Apollo, Space Shuttle, and ISS. It seems reasonable that the VSE life support designs will develop in the same way. The ECLS for spacecraft to reach ISS and the Moon can use the Shuttle and Apollo approaches. However, the long duration ECLS for the Moon base should be the same as for Mars, because the Moon will be the testbed for Mars. The ECLS for Mars could be similar to that of ISS, but it should be redesigned to incorporate lessons learned, to take advantage of twenty years technical progress, and to respond to the much more difficult launch mass and reliability requirements for Mars.
