NASA Previews Space Station Spacewalks
08.03.10
 
NASA managers discussed updated plans for two International Space Station spacewalks during a news briefing 4 p.m. Eastern on Monday, Aug. 2. Expedition 24 Flight Engineers Doug Wheelock and Tracy Caldwell Dyson

are scheduled to perform two spacewalks. The two NASA astronauts will

replace an ammonia coolant pump that failed July 31.  The problem

caused a significant power down and required adjustments to provide

the maximum redundancy possible for station systems. The systems

are stable, and the six crew members aboard are not in any danger.

Thursday's spacewalk will be dedicated to the pump module replacement.

Another spacewalk will be scheduled a few days later to complete the repairs.  Spacewalk coverage begins 5 a.m. on Thursday, Aug. 5.

Cut 1 00:22 – “As a result of that anomaly the ops team did a fabulous job of reconfiguring the vehicle, shedding loads off of that thermal system,  and either powering off systems or transferring the load to the other power stings that were cooled by the B pump on the port side of the system.”
