Third and Final Spacewalk for STS-132 Crew Today

The crew of space shuttle Atlantis is focusing on the third and final spacewalk of the mission. Astronauts will install a jumper, swap out batteries and retrieve a grapple fixture during the excursion.

Space shuttle Atlantis, docked to the International Space Station, is featured in this image photographed by an STS-132 spacewalker during the mission's first spacewalk.

Mission Specialists Michael Good and Garrett Reisman will perform the extravehicular activity that will finish the last of the battery exchanges and a few additional tasks.

The two are expected to egress from the Quest airlock at 6:45 a.m. EDT. Their first task will be the installation of a nitrogen jumper on the port 4 and 5 truss. Next, they will finish the last of the battery replacement work, swapping the remaining two batteries and installing a battery that was left in a temporary stow position from the last spacewalk.

The final planned task is the retrieval of a Power and Data Grapple Fixture (PDGF) from the orbiter’s payload bay to bring inside the station at the end of the spacewalk. The PDGF will be installed to the Zarya module’s exterior on a spacewalk later this summer.

Pilot Tony Antonelli and Mission Specialist Steve Bowen will assist from inside the complex throughout the spacewalk. Mission Specialist Piers Sellers and Expedition 23 Flight Engineer Tracy Caldwell Dyson will provide robotics support. STS-132 Commander Ken Ham will oversee the activities and assist with orbiter activities and transfer work.
