Coolant loop A, one of two used to dissipate the heat generated by the space station's electronic systems, was partially shut down Dec. 11 when a flow control valve in an ammonia pump module malfunctioned, resulting in lower-than-allowable temperatures. Non-essential systems in the station's forward modules had to be shut down, including many of the lab's major research facilities.

During an earlier spacewalkSaturday, astronauts Rick Mastracchio and Mike Hopkins disconnected and removed the suspect pump module from its rack on the right side of the station's power truss. In a second spacewalkTuesday, the astronauts successfully installed a spare pump module and reconnected ammonia coolant lines and electrical cables.

Flight controllers performed a brief "aliveness" test before the second spacewalk was over. Then, starting around4:30 p.m. EST(GMT-5), commands were uplinked to start pressurizing the new pump.

"Reactivation of the pump now is complete, and it is performing its job regulating the flow and temperature of the ammonia in loop A of the two-loop cooling system," NASA said in a statement.

Equipment normally cooled by loop A and powered down in the wake of the pump module valve problem will be reactivated over the next several days, the statement said. Other components that were temporarily switched over to coolant loop B will be returned to loop A in a carefully orchestrated sequence.

Tuesday's spacewalk was the 258th by U.S. astronauts, the 176th devoted to station assembly and maintenance since construction began in 1998, the 10th so far this year, the eighth for Mastracchio and the second for Hopkins.

Mastracchio's total through eight spacewalks now stands at 51 hours and 28 minutes, moving him up to sixth on the list of most experienced spacewalkers. Hopkins total EVA time through two spacewalks stands at 12 hours and 58 minutes.

One hundred and 14 astronauts and cosmonauts have now spent 1,107 hours and 37 minutes of spacewalk time building and maintaining the International Space Station since construction began in 1998.
