...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

Even if Hayabusa only returned a quarter of NEAR's data volume (and I'm not suggesting I know what the fraction would be) - it's still important because it's a different world. We now have a very nice new data set for Itokawa which we didn't have before, so that's good. I absolutely agree JAXA's efforts are underfunded, but that's a political issue for Japan to resolve itself.
Actually, I think JAXA hurt itself a bit in its list of mission objectives. They assigned points to each mission phase, but they were too much weighted towards the final stages. I would have weighted them more heavily for the work done up to now, so that a more substantial degree of success would be shown today. The remote sensing was very valuable. Then the sample return would be 'icing on the cake' if it could be pulled off. Ahh... I can almost hear the sound of the milk of human kindness sloshing around in me today. 'tis the season... I guess. Phil -------------------- ... because the Solar System ain't gonna map itself.

Would it have been easier to have Hayabusa touch down on several different places on Itokawa to take images and data, rather than have brought Minerva along to do that job?
Or even just one stationary lander to leave on the planetoid? -------------------- "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 |
