Yesterday, two astronauts completed a seven hour spacewalk
to finish installation of a spare coolant pump after a failed coolant pump
forced a partial shut down of the ISS. As of late yesterday afternoon, that pump is online and operating normally
: "The new pump now is considered fully functional, but it will take some time to fully reintegrate the pump and Loop A of the two-loop external cooling system. Teams at mission control are following a schedule that should allow the restored cooling loop to be fully activated and integrated into the station’s cooling system on Christmas Day, Dec. 25. ... Electrical systems that depend on cooling from Loop A will be repowered or moved back from temporary support on Loop B gradually on Thursday, Friday, and throughout the weekend."
