Mission Control Center, Houston, Texas
Today, the shuttle and station crews will focus on the third spacewalk of the mission. Astronauts will install a jumper, swap out batteries and retrieve a grapple fixture during the excursion.
The crew woke at 12:50 a.m. CDT to "Traveling Light" performed by JJ Cale. The song was played for Mission Specialist Piers Sellers.
The shuttle crew of Commander Ken Ham, Pilot Tony Antonelli, and Mission Specialists Michael Good, Garrett Reisman, Steve Bowen and Sellers will focus on the spacewalk. Reisman and Good 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 5:45 a.m. 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.
Antonelli and Bowen will assist from inside the complex throughout the spacewalk. Sellers and Expedition 23 Flight Engineer Tracy Caldwell Dyson will provide robotics support. Ham will oversee the activities and assist with orbiter activities and transfer work.
On the International Space Station, Expedition 23 Commander Oleg Kotov and Flight Engineers Alexander Skvortsov, Mikhail Kornienko, Soichi Noguchi and T.J. Creamer will continue station science work and departure preparations for the upcoming Soyuz TMA-17 undocking.
The next status report will be issued at the end of the crew workday, or earlier if warranted.
