...starting a new thread for Hayabusa's sampling feedback and the return voyage.
After its nail-biting success in November, will there be enough fuel for the Falcon to make it home? -------------------- --O'Dave

If Hayabusa's thrusters persist in being only half-useful, traveling with the asteroid until it gets closer to Earth may be the only choice - unless of course they won't be able to generate enough thrust before Earth flies away regardless.. Yet another cliffhanger.

QUOTE (mike @ Dec 1 2005, 04:18 AM) If Hayabusa's thrusters persist in being only half-useful, traveling with the asteroid until it gets closer to Earth may be the only choice - unless of course they won't be able to generate enough thrust before Earth flies away regardless.. Yet another cliffhanger. My understanding is that they have a heating system of some kind but are cautious about collateral effects from too much heat. I would guess that if it came to an all-or-nothing point they could decide to take their chance and try to heat up the frozen thrusters. -------------------- If Occam had heard my theory, things would be very different now.

Would it be possible to send out a probe to snag Hayabusa and bring it back to Earth with its surface samples? Or maybe remove just the samples and bring them back?
I think either scenario would be easier than trying a landing again on the planetoid at this point. -------------------- "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 |
