In this image taken from video and made available by NASA, astronauts Douglas Wheelock, right, and Tracy Caldwell Dyson work 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)
