- - o.k., I'm not an aerospace engineer, just a biology major, but I was
- -wondering what the outlook is, in the near future, for establishing a lunar base.
- - It seems logical to me that before we start planning a manned mission to Mars,
- -we ought to start planning a permanent base on the moon. Is NASA devoting any
- -time or resources toward this direction?
-
- There's some low level of effort in that direction. Galileo did some lunar
- science on the recent flyby, Clementine is apparently scheduled to launch
- early next year, and there are proposals for further lunar science missions
- and some work on planning manned missions. Some of the work done on SSF should
- be applicable to establishing a lunar base. We'll probably have a better idea
- of how much interest the new Administration has in a lunar base (and if there
- is interest, how much they'll be able to sell to Congress) in 100-200 days.
- My impression is that a lunar base is of more near-term interest than a
- Mars mission.
-
- - also, does anybody know how the life-support/environment control systems
- -will operate on the space station Freedom (or how they operate on mir)? I
- -suppose that these technologies will come in handy when we establish a base on
- -the moon. How is oxygen replenished, what's the waste managment program,
- -and how will they replenish the water supply.
-
- This was discussed in May 1992. According to Henry Spencer, there are plans
- to recycle the water (though perhaps mainly for washing, etc.). Dani Eder
- says that SSF is scheduled to import all its oxygen for a few years, then
- eventually start recycling its CO2 to recover some of the oxygen. Also
- according to Henry, the "last-but-one" design of SSF was to use excess water
- as reaction mass for reboost and orbital maneuvering, but this was called off
- due to design cost constraints.
