Space station pump out, crew safe

WASHINGTON – NASA said Wednesday it was looking into a problem with a malfunctioning cooling pump on the International Space Station, but there was no immediate danger to the six crewmen on board.

A valve on a pump on one of the station’s two external cooling loops shut down because it was too cool Wednesday, NASA spokesman Bob Jacobs said. He said that at no time was the crew at risk. But some non-critical equipment of the massive orbital outpost were powered down.

“It could be a serious problem, but it’s not an emergency,” Johnson Space Center spokesman Kelly Humphries said.

Engineers suspect a valve inside the pump was faulty and ground controllers moved electrical power supplies to the other cooling loop, Jacobs said. These loops circulate ammonia outside the station to keep equipment inside and outside cool.

Jacobs said the crew of two American astronauts, three Russian cosmonauts and a Japanese astronaut were preparing to go to bed as normal, while engineers on the ground tried to troubleshoot the problem.

Humphries said it was too early to speculate whether a spacewalk would be needed to fix the problem.
