Officials have detected a problem with a cooling system on the International Space Station, NASA spokesman Josh Byerly said.

One of two cooling pumps has failed, Byerly said.

Authorities are troubleshooting the problem and the station’s crew is not in danger, he said.

The current mission of the space station, officially called Expedition 38, is scheduled to fly until March 2014. The six-person crew consists of NASA astronauts Mike Hopkins and Rick Mastracchio of the United States; Russians Mikhail Tyurin, Sergey Ryazanskiy and Oleg Kotov; and Koichi Wakata of Japan.
