Astronauts finish first spacewalk

The shuttle in flight

Astronauts on the shuttle Discovery have carried out their first spacewalk.

Soichi Noguchi and Steve Robinson left the space ship to look to see if any damage was caused when foam fell off the craft during take-off.

It was the first time either astronaut had ever carried out a spacewalk, one of three scheduled for the mission.

Nasa is still looking as images of Discovery taken to inspect for damage, but is confident the space shuttle will make a safe return to Earth.

Mission known as STS-114
Discovery's 31st flight
17th orbiter flight to ISS
Location: Kennedy Space Center, Launch Pad 39B
Discovery crew: Collins, Kelly, Noguchi, Robinson, Thomas, Lawrence and Camarda

On Friday, the astronauts prepared for the walk by breathing pure oxygen for one hour.

Discovery's crew also dropped the cabin pressure in the shuttle to help the spacewalkers prepare for the lowered pressure in their spacesuits.


During the walk the astronauts did some experiments on how to repair some parts of the shuttle. These methods might one day be used in space for real.

Discovery docked on the International Space Station (ISS) on Thursday, two days after launching from Florida.

The shuttle is expected to extend its 12-day mission by one day, because crew on the International Space Station want help carrying out some work there.
