...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

Holder of the Two Leashes:
"...One other thing I don't understand, though, is what your whole point is. ..." I guess my points is that NEAR was the first of the Smaller, Cheaper, Faster, Better missions, but there is an ongoing debate on whether it was even good enough to accomplish what I thought was it's primary mission objective: determining whether S-type asteroids are or are not the parent bodies of ordinary chondrite meteorites. While the indications of a space-weathering modified surface were at least somewhat expected to cause potential problems in linking the two, the mission that was flown carried instruments that simply did not have the signal-to-noise ratio AND the resolution to clearly sort out what appear to be end-members of the weathering sequence. It was good, but like Boris, it wasn't good-enough. Where NEAR really shined is in photo-geology, where it mostly made up for it's dinky camera with scads and scads of images that can be mosaiced into global coverage, and revolutionized our understanding of geologic processes on asteroids. |
