At the afternoon seminar on Dec 12, 2005 at the Hayden Planetarium, Steve Squyres also talked a little about MSL (he is a member of MSL's review board). I apologise if some of these notes are redundant in this forum:
- MSL's skycrane technology will be tested via a physical simulator in addition to computer simulations; quite an elaborate setup is being constructed for this purpose at JPL. - There will be no "local" landing control, i.e. if unlucky, MSL could land right on top of a rock. - The re-entry capsule's center of gravity will be offset from the geometric center and thus dynamic steering (a la Apollo) will be possible - and indeed required, to meet the much smaller landing ellipse [10km instead of 50km I think he said?].

Airbag  I thought the whole point of having the skycrane was so that MSL would *not* land on top of a big rock? -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
