SUNDAY, JULY 19, 2009The astronauts have wrapped up another day aboard the combined space shuttle and space station complex 220 miles in orbit. The crew will be awakened at 6:33 a.m. EDT (1033 GMT) to begin Flight Day 6.
2255 GMT (6:55 p.m. EDT)Space station residents Frank De Winne of the European Space Agency and Mike Barratt of NASA are spending their Sunday evening working plumbers in the Waste and Hygiene Compartment. Wearing goggles and protective gloves, the astronauts are trying to understand the condition of equipment inside the space toilet and replacing parts with spares to get the system working again.
2223 GMT (6:23 p.m. EDT)Space station astronaut Robert Thirsk says the crew hopes to have the U.S. toilet repaired and working again by tomorrow morning.
1853 GMT (2:53 p.m. EDT)Mission Control tells space station astronaut Frank De Winne that removal and replacement of some parts in the U.S. toilet is likely to be ordered. The toilet malfunctioned earlier today. Ground teams have been analyzing the data and determining what needs to be done to fix the problem.
1810 GMT (2:10 p.m. EDT)With the day's robotic operations successfully completed, the astronauts are spending this afternoon making repairs to the space station's Advanced Resistive Exercise Device by replacing a shock absorber. The device is one of the station's exercise machines. In the Quest airlock module, Dave Wolf and Tom Marshburn are organizing tools and equipment for their spacewalk tomorrow. And the transfer of logistics into the station from the shuttle's crew module is continuing.
1658 GMT (12:58 p.m. EDT)The cargo carrier has been installed onto the space station's mobile railcar, completing one of the main tasks for today.
1636 GMT (12:36 p.m. EDT)Mission Control has given a "go" to resume robot arm activities to install the cargo carrier. The ground team wanted to look at a momentary issue with one of the command-and-control computers aboard the station.
1623 GMT (12:23 p.m. EDT)The robot arm operators have been instructed to hold off moving the arm further while Mission Control looks at a computer issue.
1605 GMT (12:05 p.m. EDT)The cargo carrier is being lined up with the parking spot on the space station's mobile base system. The fixure where the pallet will be left is known as the POA. It resembles an end of the station's arm, and will hold the structure during tomorrow's spacewalk and unloading operations.
1555 GMT (11:55 a.m. EDT)The new toilet in the U.S. Destiny laboratory module aboard the International Space Station, currently hosting a combined crew of 13, malfunctioned today. Flight controllers told the astronauts to use toilets in the Russian part of the station and aboard the shuttle Endeavour until the problem is resolved.

1538 GMT (11:38 a.m. EDT)Julie Payette and Tim Kopra have the station robot arm in motion with the cargo carrier perched on the end.
1532 GMT (11:32 a.m. EDT)Ground teams are working on a troubleshooting plan for the U.S. toilet in the Destiny laboratory. An internal pump apparently got flooded with chemicals. The station's Russian toilet and the shuttle toilet are available for the astronauts to use in the meantime.
1527 GMT (11:27 a.m. EDT)The station's arm has the pallet and Endeavour's just let go.
1511 GMT (11:11 a.m. EDT)The space station's robot arm is reaching to grab the pallet for handoff from the shuttle arm.
1500 GMT (11:00 a.m. EDT)This pallet's formal name is the Integrated Cargo Carrier - Vertical Light Deployable, or ICC-VLD. The astronauts call it "Vic" for vertical cargo carrier.
The structure is 8 feet long and 13 feet wide. Its mass with the payloads loaded aboard is more than four tons.
1412 GMT (10:12 a.m. EDT)A small pallet stacked with spare parts and fresh batteries for the International Space Station has been lifted out of shuttle Endeavour's payload bay by the orbiter's robotic arm.
The shuttle and station arms will again work in tandem to move the carrier just like yesterday's activities with the Japanese Exposed Facility. After Endeavour's arm maneuvers this carrier to left side of the shuttle, the station arm will take over. A couple of hours from now, the pallet will be anchored to an attachment port on the station's mobile base railcar.
Spacewalkers on upcoming EVAs will unload the pallet's contents, which include a replacement thermal control system pump, a drive unit for the station's railcar and a six-foot-diameter Ku-band communications dish, plus six batteries to swap out with those on the Port 6 solar power module that's nearing nine years old already.
Once the payloads are removed from the carrier and the old batteries are stowed aboard, the structure will be placed back into Endeavour's payload bay late in the mission for return to Earth.
1405 GMT (10:05 a.m. EDT)Endeavour's robot arm is in motion to unberth the carrier.
1400 GMT (10:00 a.m. EDT)The 13-member shuttle-space station crew is working through a revised timeline today, focusing on logistics transfers, spacewalk preparations and the robotic transfer of spare parts and equipment from Endeavour to a work site on the station's solar power truss.

1359 GMT (9:59 a.m. EDT)The latches holding the pallet in the shuttle's payload bay have been released.
1346 GMT (9:46 a.m. EDT)Shuttle Endeavour's robot arm, under the control of commander Mark Polansky and pilot Doug Hurley, has grappled the spare parts cargo carrier for unberthing from the payload bay and handoff to the station's arm today.
1300 GMT (9:00 a.m. EDT)The latest version of the NASA Television schedule (Rev. H) can be downloaded here.
1034 GMT (6:34 a.m. EDT)Flight Day 5 just began with "Learning to Fly" by Tom Petty and the Heartbreakers as the wakeup song played for Chris Cassidy.
0215 GMT (10:15 p.m. EDT Sat.)The crew signed off for the night with shuttle commander Mark Polansky offering condolances on the passing of Walter Cronkite.
The astronauts completed the primary objective of the mission by successfully installing the Japanese exposure facility on Saturday.
They'll be awakened at 6:33 a.m. EDT Sunday for a day devoted to moving the cargo carrier loaded with spare parts from the shuttle payload bay to the station's mobile base system and making repairs on a piece of the station's exercise equipment.
0100 GMT (9:00 p.m. EDT Sat.)NASA's Debris Analysis Team is in the final stages of reviewing launch and on-orbit photography of the shuttle Endeavour's heat shield. The ship's nose cap and wing leading edge panels have been cleared for entry as is and while 16 areas have been identified with minor tile damage, engineers have not seen anything that warrants repairs or additional inspections, a senior manager said Saturday.
