Spacewalkers to unload spare parts from carrier

Astronauts David Wolf and Thomas Marshburn are preparing for a planned six-and-a-half-hour spacewalk today to move critical spare parts to the International Space Station as a hedge against failures after the shuttle is retired. Crewmates inside, meanwhile, will continue work to repair the toilet in the U.S. lab module after a malfunction Sunday.

"On EVA 2 we will be moving three boxes, space-to-ground antenna, a pump module and a linear drive unit (for the station's robot arm transporter)," Wolf said in a NASA interview. "These are critical spares to survival of the space station in the years past shuttle retirement.

"In the case of the space-to-ground antenna, it has a very delicate, large antenna. I'll be holding this box through a very large maneuver (on the end of the station's robot arm) as we bring it in to the stowage platform. Part of the structure of the stowage platform will actually come within an inch or so of this delicate antenna, so Tom and I will be manipulating this box slowly down, kind of holding our breath. And I can tell you after we get that locked into place and didn't damage that antenna, I'm going to be breathing a lot easier."

Today's spacewalk, scheduled to begin around 11:28 a.m., is the 127th EVA devoted to station assembly and maintenance since construction began in 1998, the eighth so far this year and the second of five planned for Endeavour's crew. It will be Wolf's sixth spacewalk and Marshburn's first.

For identification, Wolf, call sign EV-1, will be wearing a spacesuit with solid red stripes around the legs. Marshburn, EV-2, will be wearing a suit with broken stripes.

After the antenna, the 1,300-pound pump module and the drive unit are transferred to external storage platform No. 3, Wolf and Marshburn will move up to the newly installed Japanese Exposed Facility experiment platform on the outboard end of the Kibo lab module and attach the first of two television cameras. The cameras are needed for normal operations and for the September approach of a new Japanese cargo ship. A second camera will be installed later in the mission.

The official crew patch for Endeavour's flight to finish building Japan's section of the space station is available in the Spaceflight Now Store.

Space station commander Gennady Padalka and Frank De Winne, meanwhile, will work in the Destiny laboratory module to replace components in the waste and hygiene compartment, or WHC, a NASA-supplied, Russian-inspired toilet that's tied into the U.S. segment's water and urine recycling system.

The high-tech toilet malfunctioned Sunday when chemically treated water "flooded" a pump module and contaminate several other components.

Space station Flight Director Derek Hassman said early Monday that engineers are hopeful the toilet can be repaired and returned to service in short order.

"It's actually going very well," he said. "When we first started seeing the issues early in the crew day yesterday, there was a lot of concern it may take multiple days, if not close to a week, to recover the toilet functionality, which is obviously a big deal with this many people on board."

The shuttle-space station complex currently is hosting a record combined crew of 13 astronauts and cosmonauts. The station is equipped with two toilets for its six-person crew, the one that malfunctioned and one in the Russian Zvezda command module. The space shuttle Endeavour also is equipped with a toilet. After the malfunction Sunday, the station crew was told to use the Russian potty and Endeavour's seven-member crew was told to use the shuttle's.

"As it turns out, on the second half of the crew day we were able to remove a number of the components in the toilet system that were affected by the failure we saw," Hassmann said. "(Today) there are two more components in the system that we're going to replace. There are between six and seven individual components that by the middle of the crew day we expect to have been removed and replaced. These are all spares that are designed to be changed out.

"So we made a lot of progress much quicker than we expected initially based on the initial signatures we saw," he said. "I have some hope that by the end of the crew day we may have recovered the functionality."

Today is the 40th anniversary of the Apollo 11 moon landing on July 20, 1969. NASA plans to hold an Apollo news conference at 9:30 a.m. that will be carried on NASA television. At 8 p.m. this evening, NASA TV's public channel will carry coverage of an Apollo celebration at the Smithsonian's Air & Space Museum. As a result, today's mission status briefing, scheduled for 8:30 p.m., will be carried on NASA's media channel.
