Space station waits for part to repair power system

Cape Canaveral, Fla. — The International Space Station has taken a power hit, and spacewalking repairs may be needed. First, though, a replacement part must be delivered via rocket.

NASA said Monday the six astronauts were left with one less power channel Friday. A short circuit in equipment on the station’s framework is to blame. The short apparently tripped a current-switching device, resulting in the loss of one of eight channels used to power the orbiting lab. The affected systems were switched to alternate lines.

NASA spokesman Dan Huot says the crew has been operating normally and is in no danger.

No good spare parts for the job are on board. NASA plans to launch a replacement on a SpaceX delivery scheduled sometime early next year.

A similar failure in 2014 required spacewalking repairs.
