Washington (AFP) Feb 28, 2011 Two American astronauts on Monday began the first of two spacewalks at the International Space Station in order to install a permanent module onto the orbiting lab, NASA said. The walk began at 9:46 am Eastern time (1546 GMT), about a half hour earlier than scheduled. Spacewalkers Steve Bowen and Alvin Drew arrived at the ISS aboard the space shuttle Discovery, which launched Thursday on its final mission before becoming the first of three spacecraft to retire this year as the American shuttle program ends. The Discovery crew is there to deliver the Permanent Multipurpose Module, with extra storage space and an area for experiments, and the Express Logistic Carrier, an external platform for large equipment. "The first spacewalk's objectives will be to install an extension cable, a pump module vent tool, a camera wedge and extensions to the mobile transporter rail," NASA said. The extension cable is being installed as preparation for the setup of the Italian-built Leonardo module as a permanent fixture at the lab. Then the astronauts will start work on "moving a failed pump module to a more permanent storage location on the space station," NASA said. The spacewalk will wrap up about six hours after it began, with the Japanese "Message in a Bottle" experiment, in which they "expose a metal canister to capture the vacuum of space," NASA said. The spacewalk is to end at 2048 GMT. The spacewalk is the sixth for Bowen, who replaced astronaut Tim Kopra after a bike accident in January, and the first for Drew, an African-American astronaut who has now become the 200th person to walk in space, NASA said.
