Spacewalkers Peggy Whitson and Dan Tani began their spacewalk today at 4:50 a.m. EST. Their activities will be similar to Tuesday’s spacewalk.
Today's spacewalk plan includes hooking up more electrical and fluid connections between the Harmony Node 2 and the Destiny laboratory. They already moved another 300-pound, 18.5 foot fluid tray, the Loop B fluid tray, from a temporary location on the station’s main truss to the Destiny lab. The Loop B fluid tray was placed on the opposite side of where the Loop A fluid tray was placed on Tuesday.

The two spacewalkers moved the 300-pound, 18.5 foot Loop B fluid tray from the station’s main truss to the port side of Destiny and completed fluid and electrical connections.

Tani did an inspection of a Solar Alpha Rotary Joint that had previously shown increased power consumption and vibration while rotating as it followed the Sun. Whitson deployed and mated cables to be used as part of the Station to Shuttle Power Transfer System, or SSPTS. A portable foot restraint was also installed on Node 2 for upcoming spacewalks when the European Columbus laboratory is installed on the STS-122 mission.

The Expedition 16 crew members aboard the International Space Station continued the internal outfitting of the Harmony node, along with routine maintenance on Tuesday.

Commander Peggy Whitson and Flight Engineer Dan Tani continued the interior outfitting of the Harmony node by performing “plumbing” work on the space connecting the Destiny Lab and the Harmony node by installing nitrogen transfer jumpers. Whitson later set up the Harmony node vestibule for depressurization and leak checking.

Flight Engineer Yuri Malenchenko worked several hours on the Service Module’s fire warning system, removing and replacing all expired smoke detectors. The crew members also completed their daily exercise program, worked on several experiments and gathered some of the tools that will be used during the STS-122 spacewalks.

The Expedition 16 crew aboard the International Space Station is preparing for the arrival of space shuttle Atlantis after its scheduled launch for the STS-122 mission on Dec. 6.

Commander Peggy Whitson and Flight Engineer Dan Tani worked Wednesday resizing spacesuits and gathering needed tools for the spacewalkers of the upcoming mission. Whitson and Tani also installed the Centerline Berthing Camera System that will be used for visual cues in the installation of the European Columbus module to the Harmony connecting node.

Whitson and Flight Engineer Yuri Malenchenko are scheduled to tag up with flight controllers in Houston to discuss their training on Rendezvous Pitch Maneuver photography they will perform as Atlantis approaches the station for docking. The photography will document the condition of Atlantis' heat shield for analysis by imagery experts at Johnson Space Center.

Leak Check Performed; Crew Prepares for Atlantis

Image Above: Commander Peggy Whitson is opening the hatch to the vestibule between the Harmony Node and the Destiny Laboratory. Image credit: NASA TV

Wednesday night the Expedition 16 crew closed hatches to the vestibule between Harmony Node and Destiny Laboratory to support a second overnight leak check. When Commander Peggy Whitson opened the Destiny Lab forward hatch Thursday morning, there did not appear to be any pressure change between the Lab and the vestibule. If there had been a leak in the vestibule, a pressure drop would have been observed. Telemetry from this morning also suggested that the vestibule did not leak overnight. Specialists in Mission Control Center Houston will continue to analyze all data from both overnight leak checks.

On Thursday, crew members gathered spacewalk tools, recharged the satellite telephone for the Soyuz TMA-11 spacecraft and performed a routine fire drill. Whitson is also scheduled to record a video tour that will be downlinked for study by the STS-122 crew for familiarization prior to their arrival at the station.

The crew continues preparing for the arrival of space shuttle Atlantis on the STS-122 mission scheduled to launch on Dec. 6.

Crew Performs Additional Leak Checks

The Expedition 16 crew performed additional leak checks Friday on the Pressurized Mating Adapter 2 (PMA-2).

After partially pressurizing PMA-2, Commander Peggy Whitson performed the leak check then initiated the depressurization of the passageway between the docking port and the Harmony node until its planned repressurization on Dec. 7 for the scheduled docking of Atlantis on the STS-122 mission.

The test repetition was requested by ground specialists because of inconclusive results of the first 15-hour leak check on the vestibule between Harmony Node and PMA-2.

Whitson also worked with an experiment that charts the growth and development of tomato plants, yeast cell genes and a crystal "garden" in the weightless environment of space, which will be compared with similar experiments being conducted in K-12 classrooms around the world.

On Saturday, Canadarm2 will be maneuvered to the correct location on the Harmony Node's Power and Data Grapple Fixture for the upcoming installation of the Columbus module.

Space shuttle Atlantis is scheduled to launch on Dec. 6 beginning the STS-122 mission to deliver and attach the European Columbus laboratory to the station.

The Expedition 16 crew aboard the International Space Station continues preparations for the arrival of space shuttle Atlantis, scheduled to launch on the STS-122 mission Thursday.

On Monday, the crew reviewed robotics plans and collected tools for use during the STS-122 spacewalks.

The crew also worked with the Coarsening in Solid Liquid Mixtures-2 (CSLM-2) experiment. CSLM-2 examines the effects of microgravity on a phenomenon called coarsening.

On Saturday, a final leak check of the vestibule between Harmony and Destiny proved that there is an air-tight seal and no degradation of pressure. After a 17-hour test, the leak rate was reported to be insignificant.

STS-122 Delayed, Station Crew Presses Ahead

Image Above: Commander Peggy Whitson floats inside the Harmony module. Image credit: NASA

STS-122, the mission to deliver and install the Columbus laboratory to the International Space Station, has been delayed until no earlier than Jan. 2, 2008.

For the latest news and information on the STS-122 mission, visit the main shuttle page.

Meanwhile, the Expedition 16 crew is pressing ahead with normal station activities including housekeeping and science experiments. The crew also monitored the refilling of ammonia in the cooling loops inside the Destiny lab.

Early Saturday, Mission Control noted the simultaneous trip of two station circuit breakers and a power surge protection device. The equipment is associated with a positioning device for the station solar arrays called a Beta Gimbal Assembly that can change the angle of one of the two wings of the S4 solar array on the station's starboard side.

Using a backup path for ground commands, controllers reset the circuit breakers and set the angle of the wing to a favorable, but temporary angle for power production, where it currently remains. Normally, the angle of the arrays changes frequently to maximize power generation. Engineers are evaluating the problem.

Neither this Beta Gimbal Assembly issue nor the unrelated issue with the Solar Alpha Rotary Joint, which rotates the starboard solar arrays, impacts current station operations.

Spacewalk Preps, Science for Expedition 16

Image Above: Flight Engineer Yuri Malenchenko takes pictures inside the Zvezda service module. Image credit: NASA

A spacewalk early next Tuesday from the International Space Station will focus on the starboard solar arrays, managers said Wednesday. Expedition 16 Commander Peggy Whitson and Flight Engineer Dan Tani will examine the starboard Solar Alpha Rotary Joint (SARJ) and return its trundle assembly to the station's interior. The SARJ allows the paddlewheel-like rotation of the starboard arrays to follow the sun as the station orbits the Earth. It has been locked since vibration and increased current draw were noted.

Whitson and Tani also will examine the Beta Gimbal Assembly (BGA). It tilts solar wings for optimal power generation. The starboard BGA also has been locked since some power feeds to it were interrupted last Saturday.

Neither problem affects current station operations.

NASA television coverage of the spacewalk will begin at 4:30 a.m. EST.

Meanwhile, Tani and Flight Engineer Yuri Malenchenko are busy performing science on the International Space Station.

Tani is documenting his sleep patterns and light exposure for an experiment. The data is logged into a laptop computer and downlinked for scientists to evaluate on Earth. Malenchenko set up a device in the Russian docking compartment to track his eye movements while performing various exercises.

Station Commander Peggy Whitson and Flight Engineer Dan Tani will perform the 100th spacewalk in support of International Space Station assembly on Tuesday, Dec. 18. They will inspect the starboard Solar Alpha Rotary Joint (SARJ) and the Beta Gimbal Assembly (BGA). The SARJ and BGA have been temporarily locked in place while the solar arrays still produce power.

Whitson and Tani completed a procedure review on Friday and held a tagup with the lead spacewalk officer on the ground.

Kirk Shireman, station program deputy manager called the spacewalk a “fact-finding mission.” The spacewalkers will report back to ground controllers what they find and return a trundle assembly back inside the station. Specialists on the ground will use the results to determine how to restore the starboard solar array's sun-tracking capability.

A move of the Mobile Transporter to worksite 4 in the center of the station's truss today from worksite 7 to provide its usual micrometeoroid debris protection was postponed Friday after station cameras detected what appeared to be a piece of insulation on the truss track. Flight controllers continue to analyze the situation.

Upcoming missions to the International Space Station include the launch of STS-122 and the delivery of the Columbus laboratory no earlier than Jan. 10. Europe’s Automated Transfer Vehicle, also known as Jules Verne, is targeted for launch to the station in mid-February. Also, the first part of Japan’s laboratory, Kibo, is scheduled for launch on space shuttle Endeavour on mission STS-123 in February.
