...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

Hayabusa returned a huge amount of infrared spectrometer data. The NEAR instrument failed early in the mission, and the high-orbit data (as I recall) didn't tell much about surface composition variation, as it was mostly unresolved. The X-Ray composition data may be significantly better than NEAR's, but published data in science result papers will tell.

QUOTE (edstrick @ Dec 19 2005, 01:00 AM) Hayabusa returned a huge amount of infrared spectrometer data. The NEAR instrument failed early in the mission, and the high-orbit data (as I recall) didn't tell much about surface composition variation, as it was mostly unresolved. The X-Ray composition data may be significantly better than NEAR's, but published data in science result papers will tell. The NIS instrument on NEAR returned three solid months worth of data from Eros before it failed. At the time, it was in a 50 km circular orbit, and able to resolve a spot 330x650 meters. This is 1 to 2 percent the length of Eros, so it was resolving the asteroid just fine. The reason it didn't show much surface variation is because, as this instrument discovered, there was no significate variation to report. The NIS also made significant contributions to studying the spectra of asteroid 253 Mathilde and comet Hyakutake. I'll concede the point made by Hugh on the picture resolution. |
