Cooling Problems Reported on Space Station

CAPE CANAVERAL, Fla., Aug. 1 (UPI) — A cooling system on the International Space Station shut down following a power surge, but the crew is in no danger, NASA reported Sunday.

The crew was sleeping when alarms sounded, warning them of problems, NASA said on its Web site.


It took the crew several hours to power down non-critical equipment as it searched for reasons for a power spike in what NASA called “Cooling Loop A.” Afterward, the rest of the crew went back to bed while American astronaut Tracy Caldwell Dyson continued searching for troubles in the problematic cooling loop.

NASA said a redundant cooling loop is keeping the ISS in a proper configuration and if it’s needed, a new cooling pump stored on the station can be installed.

“It seems like we’re in a sim right now,” flight engineer Tracy E. Caldwell Dyson told NASA flight controllers early Sunday morning. She was referring to training simulations.

Troubleshooting was to continue Sunday “to keep the station in a stable configuration, including the installation of a jumper cable to maintain proper cooling to the Zarva module on the Russian segment,” NASA said.
