- (Reformatted to be more readable, sorry.)
- I'm trying to formulate a letter on the Space Station to my Congresspeople.
- I have several questions on Space Station assembly issues that I'd
- appreciate some input on. Thanks in advance!
-
- 1. What is the current thinking on Shuttle accident probabilities and the
- impact on Space Station assembly? I recall reading of an Air Force
- assessment Post-Challenger that compounded to near certainty of a
- disabling accident in 20 flights. (Not necessarily an explosion, but at
- least removal of an Orbiter from the fleet.) If this is generally accepted,
- but not discussed, maybe it needs some airing here(!)
-
- 2. What is the status of Shuttle-C? Is it supposed to play any role in
- Station assembly or for logistical support (= hauling water & hydrazine)?
-
- 3. The only NON-POLITICAL argument that I have heard as to why Space
- Station components should NOT be launched on Energia is the comparatively
- northern latitude of the launch site and consequent payload loss for
- cross-plane maneuvers. The penalty in my estimation doesn't look that bad,
- given the large intrinsic capability of Energia, so are there
- obvious bona-fide TECHNICAL problems (e.g. no engine restart capability)
- that someone might care to comment on?
-
- 4. Does the present baseline Station have any real prospects for expansion?
- I'm thinking of intrinsic power or dynamic (structural) compromises that
- would prohibit additional modules.
