Two NASA astronauts went outside the International Space Station on Monday to move a stuck cart into its proper position. Astronauts Scott Kelly and Tim Kopra spent 3 hours and 16 minutes outside the station on an unscheduled spacewalk to move the station's Mobile Transporter, which became stuck last week about 10 centimeters from its worksite. Astronauts released brake handles on the cart, which then moved to its worksite and locked in place. The two also spent time on other get-ahead tasks, including routing a set of data cables.
