Atlantis crew on third Hubble Telescope spacewalk
Two spacewalking astronauts have tackled one of their toughest repairs to the Hubble Space Telescope - a meticulous fix of a broken camera - and installed a new spectrograph that can divine the properties of distant galaxies. Astronauts John Grunsfeld and Andrew Feustel spent 6.5 hours outside the shuttle Atlantis for the third of five back-to-back spacewalks to upgrade the famous space observatory for another five to ten years of work. NASA officials had billed Saturday's spacewalk as the "hold your breath" day for Atlantis' ongoing 11-day mission, the fifth and final servicing call to Hubble before the shuttle fleet is retired next year. But Grunsfeld and Feustel's tasks came off without a hitch. The work required Grunsfeld to clamber into Hubble's body, dig into its electronic guts and replace sharp-edged computer circuit boards that were never meant to be repaired in space.
