Endeavour astronauts embark on final spacewalk

Washington (AFP) May 27, 2011
The crew of the US space shuttle Endeavour began their fourth and final spacewalk Friday outside the International Space Station with a key milestone in view, NASA said.

Mission specialists Mike Fincke and Greg Chamitoff began the walkabout at 12:15 am (0415 GMT Friday) and plan to stay out for about six and a half hours.

"If the spacewalk begins on time, the 1,000th hour spent spacewalking for assembly and maintenance of the International Space Station will be reached at 5:33 am (0933 GMT)," NASA said in a statement.

The astronauts' mission is to stow the boom on the station truss, replace an electrical fixture, and work on some new installations for the Canadian robot Dextre and the new Canadarm2 base on the Russian side of the station.

The spacewalk will be the last by a US shuttle crew docked at the orbiting lab. A spacewalk is planned during the shuttle Atlantis's mission in July but will be done by the space station crew.

Endeavour blasted off on its final mission, STS-134, on May 16 with six astronauts on board -- five Americans and one Italian -- and docked at the ISS on Wednesday.

The shuttle will remain at the space station until May 30, returning to the United States on June 1.

The 30-year US space shuttle program formally ends later this year with the flight of Atlantis set for July 8, leaving Russia's space capsules as the sole option for world astronauts heading to and from the orbiting research lab.

The International Space Station's Canadarm2 is closer to having a new base of operation, giving it access to much of the orbiting laboratory's Russian segment. Endeavour Mission Specialists Drew Feustel and Mike Fincke installed a power and data grapple fixture on the Russian Zarya module during a 6-hour, 54-minute spacewalk early Wednesday. The arm can "inchworm" its way to the new base b ... read more
