Astronauts Rick Mastracchio and Mike Hopkins have just concluded what appears to have been a very successful EVA this morning. It is the first of two or perhaps three spacewalks needed to fix the balky pump in the cooling system for the station. Today they removed the failed pump and prepared for inserting a spare pump on Monday.
