Atlantis Crew Performs Final Spacewalk

Mission Specialists Michael Good and Garrett Reisman began the third and final spacewalk of the STS-132 mission at 6:27 a.m. EDT.

The spacewalkers first task was the installation of an ammonia jumper on the port 4 and 5 truss. They are finishing 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.
