STS-127 Report #22 Sunday, July 26, 2009 - 4:30 a m CDT Mission Control Center, Houston, Texas

HOUSTON – After a day of rest, the 13 astronauts and cosmonauts on the International Space Station will shift back into high gear for robotic operations and spacewalk preparations

The crew’s Sunday wake-up music was composer George Frederic Handel’s “Dixit Dominus ” The excerpt was uplinked for Canadian Space Agency astronaut Julie Payette at 3:03 a m CDT

Overnight, flight controllers continued to manually operate the Carbon Dioxide Removal Assembly (CDRA), which shares responsibility for revitalizing the station’s atmosphere with a similar Russian system They’re keeping the atmosphere at normal levels, but are refining the remote-control procedures

The U S CDRA has two “beds” that alternately collect or expel the gas byproduct of human breathing from the station The primary heater tripped a circuit breaker Saturday afternoon, and since then the ground team has been manually operating the backup heater Engineers are continuing to analyze data on the primary heater A second CDRA will be delivered to the station on STS-128 as part of the Air Revitalization System rack

Endeavour Commander Mark Polansky, Pilot Mark Hurley and Payette, along with Expedition 20 Flight Engineer Tim Kopra, will return a Japanese payload carrier to the shuttle’s cargo bay today using the shuttle and station robotic arms

Spacewalkers Chris Cassidy and Tom Marshburn, meanwhile, will ready their spacesuits and tools, and check procedures for Monday’s fifth and final STS-127 spacewalk The six new batteries installed on the Port 6 truss during the past two spacewalks accepted their initial charge and have been integrated into the station’s power grid

The station crew is scheduled to begin its sleep period at 6:03 p m , followed 30 minutes later by the shuttle crew

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

STS-127 Report #23 2:30 p m CDT Sunday, July 26, 2009 Mission Control Center, Houston, Texas

HOUSTON – In yet another deft handoff maneuver, the space shuttle robotic arm this morning grabbed the Japanese Exposed Section cargo carrier from the International Space Station robotic arm and carefully placed the cargo carrier back into Endeavour’s payload bay bringing to close this mission’s robotics work on the space station’s new porch

The 13 crew members aboard the space station and space shuttle today transitioned back to work by tucking the Exposed Section away, hosting a joint crew news conference and studying the new procedures for tomorrow’s fifth and final spacewalk

Endeavour Commander Mark Polansky, Pilot Doug Hurley and Mission Specialist Julie Payette, along with Expedition 20 Flight Engineer Tim Kopra, used the shuttle and station robotic arms to return the cargo carrier to the shuttle’s bay, concluding robotic activities until after undocking

Meanwhile, spacewalkers Chris Cassidy and Tom Marshburn prepared their spacesuits and tools, and reviewed procedures for the last planned spacewalk of the mission The spacewalk will focus on four tasks and is expected to run about six and a half hours

The Carbon Dioxide Removal Assembly (CDRA), which along with a similar Russian system removes carbon dioxide from the station’s atmosphere, is continuing to operate in manual mode The primary heater tripped a circuit breaker Saturday afternoon, and since then the ground team has been manually operating the backup heater

Engineers are continuing to analyze data on the primary heater A second CDRA will be delivered to the station on STS-128 as part of the Air Revitalization System rack

The station crew is scheduled to begin its sleep period at 6:03 p m followed 30 minutes later by the shuttle crew

The next shuttle status report will be issued following crew wake up or earlier if warranted
