...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

Lots of good info in those new translations - the volunteer work is much appreciated! For those who haven't read it yet, there is some hope for getting some kind of sample back:
QUOTE Asahi: What do you think of the possibility that the sample were stirred up by the landing and actually gathered? [...]
Kawaguchi: Escape velocity from Itokawa is equivalent to the speed of a pencil dropped from 0.5 millimeter height. It would only bounce up 0.5mm on earth, but on Itokawa where the gravity is small it would jump up more than 10 meters. Buton the second touchdown, the vehicle actually touched the ground for only a second and ascended back, so the sampler horn ascended with the sample, thus the sample would not have reached the capsule. In the touchdown on 20th the vehicle landed on the surface for substantially long time, so we think it is highly probable that the sample that were stirred up have entered the capsule. -------------------- --O'Dave
