Repaired Hubble Spectrograph Powers Up
17 May 2009 4:57 p.m. EDT

HOUSTON ? As astronauts Michael Massimino and Michael Good cleaning up the tools the used to repair Hubble?s ailing STIS spectrograph, a test by ground controllers has successfully powered up the instrument in a so-called ?aliveness test.? Massimino has just reported seeing what appeared to be a small tear in the palm of his left spacesuit glove.

?I can see what looks like something white underneath,? Massimino said. Mission Control evaluated video of the tear and checked Massimino's suit pressure, which is fine. There's no need for him to make an emergency run to the Atlantis airlock.

Mission Control has decided that the already over-long spacewalk will not include a maintenance chore to install insulation on Hubble. That task will be moved to a final spacewalk tomorrow.?

Spacewalkers Have Plan C for Stuck Hubble Bolt
17 May 2009 12:49 p.m. EDT

HOUSTON ? NASA has a new plan for spacewalker Michael Massimino: rip off the stuck handrail bolt with brute force. It?s Plan C after more gentle attempts to unscrew the bolt didn?t work.

Mission Control told Massimino that he?d have to give the handrail a good pull to bend it and shear off the stuck bolt.

?I think you?ve got that in you,? astronaut Andrew Feustel told the spacewalk.

?I can try,? Massimino said.

The handrail is blocking Massimino?s access to a cover plate with 111 smaller screws ? he already removed a few others ? that he has to remove in order to reach the broken STIS spectrograph today.

Hubble Screw Stuck Fast, Spacewalkers Draw New Plan
17 May 2009 12:19 p.m. EDT

HOUSTON ? The stubborn handrail bolt that refuses to budge for the spacewalker Michael Massimino appears to be stuck fast, and possibly stripped. Massimino?s attempt to remove the screw using a new bit failed to work.

?Houston, Plan B is not working, we?re looking forward to your suggestions,? astronaut Andrew Feustel radioed down from Atlantis.

?What?s Plan C?? Massimino asked. Mission Control has sent the spacewalker for more tools, these ones built to remove the handrail?s foundation, which should do the trick.

Spacewalkers Tackle Stubborn Hubble Screw
17 May 2009 11:55 a.m. EDT

HOUSTON ? Spacewalker Michael Massimino has hit a snag as he tries to remove a handrail from the exterior of the electronics box he is trying to access to fix Hubble?s STIS spectrograph. One of four screws holding the handrail in place is not coming out. Mission Control has suggested he try again with a new screwdriver bit.

?Do we have a plan if the new bit doesn?t work? Can we try keeping the handrail on or something?? Massimino asked.

Mission Control hopes the new bit will work. But engineers are studying other fixes.

?We?re working on Plan C, I guess,? Mission Control told Massimino.

NASA: Hubble Camera Fix Only Partial Success
17 May 2009 1:03 a.m. EDT

HOUSTON ? After a series of late-night tests, Hubble Space Telescope engineers have determined that the ambitious spacewalk repair of the observatory?s Advanced Camera for Surveys met with only partial success, with one of the instrument?s photo imaging channels now likely permanently offline.

Spacewalkers replaced electronics cards in the camera on Saturday during a never-before-attempted repair to revive the ailing camera, which suffered an electrical short in 2007 that shut down two of its three science channels. The survey camera includes a solar blind channel sensitive to ultraviolet light, a wide-field camera channel and a high-resolution camera channel.

During Saturday?s spacewalk, astronauts made repairs to the camera?s wide-field channel in order to restore power to the system. Because of time-constraints, NASA opted not to attempt to replace similar cards in the high-resolution channel. Instead, engineers on Earth hoped to reroute power to that channel through its wide-field counterpart. But they discovered late Saturday that that option would not work.

?The electrical short that they suspected in that camera was actually upstream of where the astronauts were working today,? NASA commentator Josh Byerly said on NASA TV. ?The repair did not work.?

Before the ambitious camera fix, Atlantis astronauts and Hubble scientists repeatedly stressed that never-before had such repairs been attempted. Even if the actual spacewalks went flawlessly, as Saturday?s did, there were no guarantees that the fixes would work, they added.

Byerly said that Hubble managers still consider the camera?s repair attempt a success. Of all the science performed by the instrument, 95 percent of it is with the wide-field channel.
