Astronauts carry out space walk
Astronauts who travelled to the International Space Station (ISS) on board the Shuttle Endeavour have carried out the first of three space walks.
Crew members Bob Behnken and Nicholas Patrick installed two modules into the ISS - a hub that will house a toilet and exercise gear, and a seven-sided dome for the crew to view the earth.
Using robotics, the astronauts had successfully installed both modules relatively quickly, according to Twitter updates on NASA's website.
On Saturday, the astronauts are scheduled to make their second spacewalk of the mission focused on installing plumbing.
