STS-127 Report #18 Friday, July 24, 2009 - 6:30 a m CDT Mission Control Center, Houston, Texas

STS-127 Mission Specialists Chris Cassidy and Tom Marshburn will tackle a challenging 7 ½-hour spacewalk today to finish swapping out batteries for the International Space Station’s oldest set of solar arrays

The joint crew of Endeavour and the station was awakened at 4:03 a m CDT by Pink Floyd’s “Wish You Were Here,” offered up for lead spacewalker Dave Wolf

Endeavour’s spacewalkers are scheduled to float out the Quest airlock hatch at 8:58 a m Their outing will be devoted entirely to finishing the work started on the third spacewalk of the mission – removing old batteries from the Port 6 truss structure and transferring new batteries from the Integrated Cargo Carrier on the end of the station’s robotic arm to the empty sockets on the truss

Pilot Doug Hurley and Mission Specialist Julie Payette will position Canadarm2 near the truss for the spacewalk and, once all of the battery swaps are complete, maneuver the carrier back into Endeavour’s cargo bay That maneuver will require them to hand off the carrier to the shuttle’s arm for re-berthing by Hurley and Commander Mark Polansky

The Progress 34 cargo ship launched on time today from the Baikonur Cosmodrome in Kazakhstan at 5:56:56 a m (4:56:56 p m Baikonur time) to begin its five-day journey to the International Space Station Less than 9 minutes later, the unpiloted cargo ship reached orbit and deployed its solar arrays and navigational antennas Two rendezvous burns of the Progress engines are scheduled today and another burn is planned for tomorrow to fine-tune the Progress’ path to the station

At the time of launch, the shuttle/station complex and its 13 crew members were flying 218 statute miles over Sapporo, Japan

Carrying 2½ tons of food, fuel and supplies for the station crew, the Progress is scheduled to dock to the aft port of the Zvezda service module at 6:16 a m Wednesday, July 29, one day after Endeavour undocks from the outpost

Expedition 20 Commander Gennady Padalka and Flight Engineers Mike Barratt, Tim Kopra, Roman Romanenko, Bob Thirsk and Frank De Winne will continue to maintain station systems and work with onboard experiments

The station crew is scheduled to begin its sleep period about 7 p m , and the shuttle crew at 7:30 p m

The next mission status report will be issued at the conclusion of the spacewalk, or earlier if warranted

STS-127 Report #19 Friday, July 24, 2009 - 7 p m CDT Mission Control Center, Houston, Texas

HOUSTON – Mission specialists Chris Cassidy and Tom Marshburn finished replacing batteries on the International Space Station’s oldest solar arrays during a seven-hour, 12-minute spacewalk – the fourth of five planned during space shuttle Endeavour’s STS-127 mission

They installed four of six new batteries for the P6 Truss structure, where a pair of solar array wings collects sunlight for power generation They stored four more of the old batteries onto a cargo carrier for return to Earth That completed the work with all 12 new and old batteries, which was begun on the mission’s third spacewalk by Cassidy and Mission Specialist Dave Wolf Higher than expected carbon dioxide levels in Cassidy’s suit limited that spacewalk’s duration, so the remaining battery tasks were deferred until today

Inside the complex, Tim Kopra choreographed the activities Mission specialists Koichi Wakata and Julie Payette used Canadarm2 – the station’s robotic arm – to hand the Integrated Cargo Carrier with the old batteries to the shuttle’s arm Pilot Doug Hurley and Commander Mark Polansky then secured the carrier in Endeavour’s cargo bay at 5:52 p m for return home

This was the fourth of five STS-127 spacewalks, the 129th in support of International Space Station assembly and maintenance, totaling 805 hours, 42 minutes It was the 101st spacewalk conducted out of space station airlocks and the 217th American spacewalk in history It was the second for Cassidy and Marshburn

The mission’s final planned spacewalk is Monday, performed by Marshburn and Cassidy together again to work on various tasks around the outside of the station

The station crew is scheduled to begin its sleep period about 7 p m , followed 30 minutes by the shuttle crew Mission Control’s musical wake up is scheduled for 3:33 a m Saturday

The next mission status report will be issued after crew wake, or earlier if warranted
