Two space station astronauts have embarked on a six hour spacewalk to do maintenance work.
The spacewalk, 220 miles above earth, took place on the eve of space shuttle Discovery's launch to the orbiting outpost.
American commander Mike Fincke, and Russian Yuri Lonchakov, had the task of undertaking repairs that they did not get to do during a spacewalk just before Christmas.
