Discovery astronauts begin spacewalk
Washington, April 09: Two astronauts from the shuttle Discovery began a six-and-a-half-hour spacewalk Friday, working on an ammonia tank on the outside of the International Space Station, NASA said.
Mission specialists Clayton Anderson and Rick Mastracchio left the shuttle’s airlock today for the first of three space walks during the 13-day mission to resupply the space station.
Mastracchio, the lead spacewalker, was seen in images beamed to Earth working on an ammonia tank on the outside of the space station, which will be replaced with a new tank.
