This postponement will allow Expedition 38 flight engineers Mike Hopkins and Rick Mastrachio to conduct a trio of EVAs outside the orbiting complex in an effort to repair the faulty pump module. These three spacewalks will take place on December 21, 23 and 25. Each EVA will commence at 12:10 p.m. Irish Time.
They will replace it with an existing spare that is stored on an external stowage platform. The pump is associated with one of the station's two external cooling loops, which circulate ammonia outside the station to keep both internal and external equipment cool.
This is the same pump which was repaired by Expedition 24 flight engineers Doug Wheelock and Tracy Caldwell Dyson, after completing three spacewalks in 2010.
