ISS Astronauts Start Repair Spacewalk Soon
The space station is equipped with eight huge solar arrays with each having its own associated power system and ammonia is used to cool down this gear. The task of the spacewalk is to detect the source of an ammonia leak, which can put out of order one of the arrays if not isolated and repaired.
Williams will be expanding her record for having the longest time in space as a female spacewalking astronaut. She currently has 44 hours of spacewalk time and is expected to have over 50 by the end of her Thursday, Nov. 1, 2012 EVA.
