NASA astronauts Michael Good (left) and Garrett Reisman, both STS-132 mission specialists, look through the aft flight deck windows of space shuttle Atlantis on 21 May 2010 during the mission's third and final session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 46-minute spacewalk, Good and Reisman completed the installation of the final two of the six new batteries for the B side of the port 6 solar array. In addition, the astronauts installed a backup ammonia jumper cable between the port 4 and 5 trusses of the station, transferred a Power and Data Grapple Fixture from the shuttle to the station, and reconfigured some tools.
