The fifth and final planned Hubble Space Telescope spacewalk began Monday with U.S. astronauts John Grunsfeld and Drew Feustel replacing Hubble's batteries. The National Aeronautics and Space Administration astronauts, who began their spacewalk at 8:20 a.m. EDT, will replace the second of two battery modules. Each module weighs 460 pounds and contains three batteries, providing electrical power to support Hubble operations during the night portion of its orbit, NASA said. The first battery...

Spacewalkers during the fourth walk of the last Hubble servicing mission experienced troubles trying to dislodge a balky bolt interfering with repairs on Sunday.Atlantis astronaut Michael Massimino used brute force to remove a bolt that was attaching a hand rail to the outside of a scientific instrument that was needing to be fixed.  The rail needed to be removed or at least bent out of the way in order to complete the task.  This just added to other smaller problems that put the...

A U.S. astronaut successfully repaired a camera on the Hubble Space Telescope during a spacewalk Saturday, NASA said. John Grunsfeld, the lead spacewalker in the shuttle Atlantis crew, opened up the Advanced Camera for Surveys and replaced four failed computer cards, Florida Today reported. The fourth card is out. Woo-hoo, Grunsfeld announced. Somehow I don't think brain surgeons go 'woo-hoo' when they pull something out, a teammate inside the shuttle responded. Grunsfeld was joined on the...

U.S. astronauts prepared Saturday for their most challenging in a series of five spacewalks to repair the Hubble Space Telescope, NASA officials said. Mission specialists John Grunsfeld and Drew Feustel of the Space Shuttle Atlantis were scheduled to install a highly sophisticated spectrograph after first removing a box housing hardware that 16 years ago came to the rescue in a bid to repair the Hubble's blurry vision, Florida Today reported. After a long day of spacewalks Friday during which...
