NASA astronauts are performing a spacewalk Wednesday to make repairs to the International Space Station.
Veteran astronauts Drew Feustel and Ricky Arnold are replacing a failed cooling component. Feustel and Arnold will also install a camera system and a communications receiver on the exterior of the space station’s Destiny laboratory.
The spacewalk is expected to take about six and a half hours.
Wednesday’s mission is the space station’s 210th spacewalk. The next one is scheduled for June 14.
