...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

I would tell you some bad news…
JAXA says Hayabusa has troubled with both of main/backup thrusters. Main thruster system could turn to ice, the other one have leaked. Now they are holding press conference now. According to Matsuura's Blog. http://smatsu.air-nifty.com/lbyd/2005/11/3_dc16.html Now we can read translations. Thank you a lot, nao. |

Good translation! Worrying news, though. The main thruster system is obstructed, the backup system leaks, and they don't have attitude control. Which prevents them from using Hayabusa's HGA, and communications with the other antennae have been spotty.
Here are some snippets: QUOTE Kawaguchi:We tried to recover from the safe mode in operation via DSN at 26th night and Usuta on 27th, but the remaining system-A thrusters did not generate enough propulsion force. So we failed to restore the attitude control. It seems that some trouble in valve may cause obstruction, or the pipes may be frozen. [...] Looking at current situation, we think it takes considerable time for recovery. [...] We now will concentrate our efforts on recovery of attitude control as the top priority. But... QUOTE Fuel remains enough and the pressure is proper. [...] Unknown: Must the vehicle leave Itokawa by the beginning of December? How long can it be extended? Kawaguchi: We can extend it to the mid of December, if it has only to return. So they have a little time to play with. Good luck, guys! -------------------- --O'Dave
