"BALTIMORE Jun 24, 2006 (AP) The main camera on the Hubble Space Telescope, which has revolutionized astronomy with its stunning pictures of the universe, has stopped working, an instrument specialist who works with the camera said Saturday.
The Advanced Camera for Surveys, a third-generation instrument installed by a space shuttle crew in 2002, went off line Monday, and engineers are still trying to figure out what happened and how to repair it.
"It's still off line today," Max Mutchler, an instruments specialist at the Space Telescope Science Institute in Baltimore, said Saturday. "
Going to be a nasty blow to the HST with that offline - some of its pictures have been pretty useful..

When I heard about the failure, and then about the recovery, I thought "there's a heckuva story there somewhere".
Anybody ever heard details?

Starlord - 27 Jun 2006 01:22 GMT They turned off the flash memory and uploaded a patch to the rover that allowed it to send the flash memory without haveing to reboot, once installed they flushed the flash and had it reboot.

Thank you for this.
I love the epilogue of the first one:
"David also said that some of the real heroes of the situation were some people from CMU who had published a paper he'd heard presented many years ago who first identified the priority inversion problem and proposed the solution. He apologized for not remembering the precise details of the paper or who wrote it. Bringing things full circle, it turns out that the three authors of this result were all in the room, and at the end of the talk were encouraged by the program chair to stand and be acknowledged. They were Lui Sha, John Lehoczky, and Raj Rajkumar. When was the last time you saw a room of people cheer a group of computer science theorists for their significant practical contribution to advancing human knowledge?
:-) It was quite a moment."

Looks to be some sort of power supply problem. Hopefully they will be able to sort it out.
