Station's outdoor science deck gets its first payloads

Astronauts operating a Japanese robot arm from inside the space station's Kibo laboratory module Thursday successfully transferred three compact experiments from a shuttle pallet to a newly installed porch-like platform in a major milestone for Japan's space program.

It was the first operational use of the new robot arm and the successful experiment transfer, along with the attachment of the porch earlier in the mission, accomplished one of the mission's top priorities.

"It's emotional enough for its designers and developers to see it accommodating external users," Tetsuro Yokoyama, deputy manager of the Kibo program, said of the robot arm work. "This also gives to Japanese public an impression that Japan's human spaceflight program is getting to a new horizon of meaningful operation and utilization."

Said lead flight director Holly Ridings: "We're very, very pleased for our colleagues" at the Japanese space agency.

While the experiment transfers were going on, flight controllers were revising plans for the crew's final two spacewalks. Spacewalk No. 4, scheduled to begin at 9:58 a.m. EDT Friday, will be devoted to completing the installation of new batteries in the station's oldest set of solar arrays, work expected to take seven-and-a-half hours to complete.

Astronauts David Wolf and Christopher Cassidy attempted to replace four of the six batteries during a spacewalk Wednesday, but the excursion was cut short after just two batteries were installed because of a carbon dioxide issue with Cassidy's spacesuit.

Ridings said Thursday engineers believe the problem was triggered when Cassidy, a former Navy SEAL, got off to a fast start in his first spacewalk, overtaxing the carbon dioxide removal system.

For Friday's spacewalk, Cassidy and crewmate Thomas Marshburn were told to take their time in the initial stages of the outing to make sure the CO2-absorbing lithium hydroxide in their suits does not get over-stressed early.

Assuming all four remaining batteries are installed Friday, Ridings said, Cassidy and Marshburn likely will focus on installing two Japanese television cameras during the mission's fifth and final spacewalk Monday, along with deploying a payload mounting mechanism.

Engineers, meanwhile, are monitoring a possible problem with a "sustaining heater" used to keep one of Endeavour's electricity producing fuel cells from getting too cold.

While docked to the space station, Endeavour draws most of its power from the space station's solar arrays and the shuttle's fuel cells are operated at a low-power setting. To keep the fuel cells from getting too cold, the sustaining heater occasionally kicks in. But fuel cell No. 3's heater ran longer than expected earlier today and engineers decided to change the shuttle's power generation configuration to prevent additional problems.

"Julie, we are seeing a longer than expected cycle on the sustaining heater on fuel cell 3," mission control radioed Endeavour. "We want to load up fuel cell 3 so it will stay warm while we look at the problem. So we'd like on (cockpit panel) R-1 is the Charlie (electrical bus) tie to off, O-F-F."

"Charlie tie to off, O-F-F," Julie Payette confirmed from the shuttle.

"Good copy."

As a result of the switch throw, fuel cell No. 3 was taken out of the shared bus configuration, forcing it to generate more power and keep itself warm without having to utilize the sustaining heater. On the flip side, the powerplant will use more hydrogen and oxygen than originally planned. But as of this writing, engineers believe the power setting will permit a full-duration mission as planned.

"Fuel cell 3, we really weren't using it, it didn't have much load on it," Ridings said. "It has a sustaining heater that when it's not loaded, comes on to keep the fuel cell warm. That heater came on and it stayed on longer than expected. They're not sure why it stayed on that long, but they decided we would start using the fuel cell and put normal loads on it to warm it up above the level where the heater needs to run.

"And so the fuel cell is fine, there's nothing wrong with it, just the heater staying on longer than expected. ... It stayed on about 20 minutes, you would expect more like two or three. We put load on it so it would stay in a warm region above where that heater's required while they go off and see if the heater signature will make some sense for them."

The heater problem is not related to a subtle issue experienced by fuel cell No. 3 before launch. But in its current configuration, a problem with one of the shuttle's other two fuel cells, in combination with a "failed on" fuel cell No. 3 heater, could result in a shortened mission.

As it now stands, no such issues are expected.
