Two astronauts climbed out of an airlock on the international space station Saturday, starting a spacewalk to fix the complex's rail transporter and test whether a boom can be used to make repairs to the space shuttle.
The 6 1/2-hour jaunt, which began as the space station passed over Asia 220 miles (350 kilometers) below, was to be the first spacewalk for Mike Fossum and the fourth for British-born Piers Sellers.
"Enjoy the view, gentlemen!" NASA communicator Megan McArthur said from Houston.
Before exiting the space station, Sellers asked for an update on the World Cup and was told the finalists were Italy and France. Sellers and his crew mates on the space shuttle Discovery were launched on their trip to the space station on Tuesday, before the finalists were known.
