I felt this deserved a thread with a more positive title. I probably feel a little unjustified pride about this since my group was involved with getting ACS back up. (Not me personally, but others in the commanding group.)

Status Report #2
On Wednesday, October 4, the Advanced Camera for Surveys (ACS) Anomaly Review Board approved an on-orbit test to attempt recovery of the full operational capabilities of the High Resolution Channel (HRC).

The proposed on-orbit test involved toggling the HRC Analog Signal Processing Card 2 relay that was thought to be the most likely location of the open in the +35V bias line that caused the instrument to suspend operations on September 23.

Early on October 9 engineers sent commands to Hubble to toggle the suspect relay. Telemetry confirmed that the relay cycled open and closed as expected. Engineers determined this action succeeded in restoring the HRC at 5:40 am on October 9 during the first opportunity to restore power to the +35V bias line. Since this test was fully successful, further workarounds will not be required.

NASA engineers believe the cause of the open circuit was a tiny particle of dust or fabric physically interfering with the electrical contact.

Engineers will monitor performance of the HRC for the remainder of the week. If its performance remains stable HRC science observations will resume the week of October 15.

Additional status reports will not be issued if science observations begin next week as planned.

End of Status Report

There won't be any more reports because ACS HRC is back in the scienc timeline this week.
