NASA To Fix Hubble Trouble

(CBS/AP)  NASA will send a space shuttle to repair the 16-year-old Hubble Space Telescope, agency Administrator Michael Griffin announced Tuesday, reversing his predecessor's order that had nixed the mission.

Griffin's announcement was greeted eagerly by astronomers who feared Hubble would deteriorate before the end of the decade without new sensors and replacements for its aging batteries.

The rehab mission, likely launching in May 2008 using space shuttle Discovery, would keep Hubble working until about 2013.

The Hubble has captured some of the most spectacular images of the universe, popularizing astronomy while at the same time advancing our understanding of space.

It has enabled direct observation of the universe as it was 12 billion years ago, discovered black holes at the center of many galaxies, provided measurements that helped establish the size and age of the universe and offered evidence that the expansion of the universe is accelerating.

"The Hubble telescope has been the greatest telescope since Galileo invented the first one," said U.S. Sen. Barbara Mikulski, a fierce champion of Hubble, which is operated out of her state of Maryland. "It has gone to look at places in the universe that we didn't know existed before."

The repair mission crew will include three veterans of the last Hubble mission, in 2002, and four astronauts on their first space trip, Griffin said.

Former Administrator Sean O'Keefe scrubbed the mission about a year after the Columbia accident – which killed seven astronauts in 2003 – because of the possible risk to the crew, reports CBS News correspondent Peter King.

But Griffin says astronauts can now find damage, get to it and make minor repairs in orbit, and there will be a rescue shuttle on standby, just in case.

"The safety of our crew conducting this mission will be as much as we can possibly do," Griffin said. "We're not going to risk a crew in order to do a Hubble mission."

The Hubble mission would add two new camera instruments to the telescope, upgrade aging batteries and stabilizing equipment, add new guidance sensors and repair a light-separating spectrograph.

Griffin named the crew members as veterans Scott Altman, John Grunsfeld and Michael Massimino, and rookies Greg Johnson, Andrew Feustel, Mike Good and Megan McArthur.

"I believe the risks are worth the reward of going into space for just about any mission, in particular the Hubble mission," said astronaut Jim Newman, who was on the last space shuttle mission to Hubble in 2002.
