Space station astronauts take 2nd crack at repairs

In this image taken from video and made available by NASA, astronaut Douglas Wheelock, works on the International Space Station attempting urgent repairs to restore a crucial cooling system on Wednesday Aug. 11, 2010. The International Space Station has been operating with only half its usual cooling capability ever since an ammonia pump failed one-and-a-half weeks ago. Science research is on hold and unnecessary equipment is off until the pump can be replaced. The cooling system is crucial for keeping electronics from overheating. (AP Photo/NASA)Spacewalking astronauts relied on brute force to remove a balky ammonia line from a broken pump Wednesday, overcoming a hurdle that bogged down their previous effort to restore full cooling to the International Space Station.
