Astronauts embark on surprise spacewalk

ROUGH CUT (NO REPORTER NARRATION)

Two U.S. astronauts floated outside the International Space Station on Monday (December 21) in a hastily planned spacewalk to move a stuck rail car before a Russian cargo ship reaches the outpost on Wednesday, NASA said.

Station commander Scott Kelly and newly arrived flight engineer Timothy Kopra were due to spend about 3.5 hours on an abbreviated spacewalk to latch the stalled car into a parking spot along the station’s exterior truss.

The car serves as a mobile base for a Canadian-built robotic crane to move rails outside the station, a $100 billion research laboratory that files about 250 miles (400 km) above Earth.

The rail car jammed about 4 inches (10 cm) short of its intended latching point last Wednesday, blocked by a crew equipment cart that was left with its brake on.

Kelly and Kopra fixed the stuck rail car in 15 minutes, leaving them time to tackle work to prepare the station for new modules, according to mission commentator Rob Navias from NASA’s Johnson Space Center in Houston.
