2013-12-25 08:09:21

NASA Following two spacewalks to replace a degraded pump module on the truss, or backbone, of the International Space Station, flight controllers in the Mission Control Center at NASA's Johnson Space Center in Houston successfully restarted the new pump Tuesday night. The pump module controls the flow of ammonia through cooling loops and radiators outside the space station, and, combined with water-based cooling loops inside the station, removes excess heat into the vacuum of space....

[ Watch the video: Space Station Cooling Loop Update ] redOrbit Staff & Wire Reports - Your Universe Online A malfunction and potential coolant link on the International Space Station (ISS) forced the crew to disable some non-critical systems, the Associated Press (AP), the Washington Post and other media outlets have reported. “Earlier Wednesday, the pump module on one of the space station’s two external cooling loops automatically shut down when it reached pre-set...

NASA Says Ammonia Leak All Plugged Up
2013-05-17 11:44:30

Lee Rannals for redOrbit.com — Your Universe Online According to the Associated Press, NASA confirmed on Thursday that the ammonia leak its astronauts fixed on the International Space Station last week is officially plugged up. Astronauts aboard the space station had to quickly repair the leaky pump during an impromptu spacewalk over the weekend. The leak forced one of the station's seven power channels to go offline. "Right now, we're feeling pretty good. We definitely got...
