Astronauts wrapped up a series of spacewalks outside the International Space Station Tuesday. Bob Behnken and Chris Cassidy spent five and a half hours outside the station during the spacewalk, which started at 7:12 am EDT (1112 GMT). The two carried out a variety of maintenance tasks, such as removing handling fixtures on the solar arrays that are no longer needed, as well as preparing a docking power for a commercial airlock module to be flown to the station later this year. The spacewalk completed a series of four the two astronauts carried out, primarily to replace batteries in the station's power system.
