An electrical failure has crippled the most powerful and widely used camera aboard the Hubble Space Telescope near the end of its life expectancy, adding urgency to plans for an overhaul of the orbiting observatory by a space shuttle crew, NASA said Monday.
At most, experts can hope for only a partial restoration of the Advanced Camera for Surveys by sending commands that route electricity from a backup power source.
The powerful $75 million camera was just a month short of its five-year design life.
Hubble's total observing powers — with other cameras — cannot be fully regained until September 2008 when a team of seven shuttle astronauts is scheduled to lift off on what will be the final repair flight to the 17-year-old space telescope.
Space agency administrator Michael Griffin approved the ambitious $900 million mission on Oct. 31, reversing a decision after the 2003 Columbia tragedy to cancel the overhaul because of safety concerns.
The high-tech camera, installed by spacewalking astronauts during the most recent Hubble house call in March 2002, was used by astronomers a year later to look further into the cosmos than ever before.

'Obviously, we are very disappointed,' NASA's Preston Burch, the Hubble program manager, said Monday.

This is from a Blogger Tag:This is from a porn writer who's sarting a blog: tag_your_it
It's a blog game. I'm supposed to pick three bloggers I know and ask them to:I pick meg of Mandarin Design, STu Savory thre writer and the classic Chief Bloaging Officer Chris Locke.
1) Pick up the book that you are nearest to with 123 or more pages. (According to early versions: Don't search around and look for the "coolest" book you can find. Do what's actually next to you.)
2) Turn to page 123.
3) Locate the fifth full sentence in that page.
4) Copy that and the next two sentences that follow.
5) Tag three more bloggers to do the same.
Here's mine: Another whispered in her ear,"if she has not provided herself a great belly, he was at her service." A third said, "He warranted she was a telation of Turpin." To which on of the company, a great wit, shaking his head and then his sides , answered, "He beleived she was nearer related to Turpis"
Mines from the William Fielding novel Joseph Andrews, which I have from the library. it's a lot like a high school reading book. But it does evokre the gereral tome and preocuation of the book posted by Gary Williams at 9:04 PM | link |

Main camera on Hubble space telescope shuts down
By Ian Williams: Tuesday 30 January 2007, 14:08
NASA ENGINEERS are examining a problem with the main camera aboard the Hubble Space Telescope.
A spokesNASA told reporters that 'an electrical short in the backup system for Hubble’s Advanced Camera for Surveys (ACS) pushed the space telescope into a protective 'safe mode' over the weekend'.
Unfortunately, the camera was already relying solely on the backup system after the primary electrics malfunctioned in June of 2006.
The aging telescope has been having a hard time of things lately, with this upset being the third since June. Engineers have managed to get the rest of Hubble back up and running. Science observations will resume this week using the remaining instruments.
Astronomers are particularly irked as it was this camera's wide-field channel that allowed boffins the deepest view into the universe to date. Screensaver makers are also upset as their steady supply of pretty pictures may be affected.
Fortuitously, NASA scientists are already working on a new field camera that was originally designed to be a backup to the ACS camera, or work in tandem with it if both were fully functional. The Wide Field Camera 3 is due to installed at Hubble in September 2008." posted by Gary Williams at 10:32 AM | link |
