The transfer of items between the two spacecraft is going smoothly, as are the handover briefings for Expedition 6 Commander Ken Bowersox, Cosmonaut Nikolai Budarin and NASA ISS Science Officer Don Pettit. Expedition 5 Commander Valery Korzun, NASA Science Officer Peggy Whitson and Flight Engineer Sergei Treschev are familiarizing the new arrivals with station systems and procedure, and discussing the location of equipment and supplies on the ISS.
This afternoon, Whitson and Bowersox replaced two valves and cleared debris from vent lines of the Carbon Dioxide Removal Assembly (CDRA) in the station's U.S. Destiny laboratory. The job was completed about 8 p.m. CST. Later Mission Control radioed them that the valve replacement had been successful, but that there was a leak in one of the CDRA vacuum lines. Whitson and Bowersox began efforts to find and fix that leak late today. CDRA had not been working well for the past several weeks. A Russian system cleanses the station atmosphere of the carbon dioxide exhaled by the normal three-person crew, but CDRA is needed to handle the load of larger crews.
NBC's Jay Leno wished Endeavour Commander Jim Wetherbee a happy 50th birthday. The good wishes were videotaped during Leno's show and transmitted to Endeavour via Houston's Mission Control Center.
This afternoon Wetherbee, Endeavour Pilot Paul Lockhart, Lopez-Alegria and Herrington talked with reporters from KFOR-TV of Oklahoma City, Okla., the Chickasaw Times newspaper; and the Cadena Ser radio network of Spain. The radio network spoke with Lopez-Alegria in Spanish.
Endeavour performed the first of three scheduled reboosts of the station a little after 11 a.m., increasing the altitude of the orbiting laboratory by about 2.8 statute miles. That left the average altitude of the station and Endeavour at almost 244 statute miles. Subsequent reboosts are scheduled for Friday and Sunday.
Thursday's second of three STS-113 spacewalks will see Lopez-Alegria and Herrington make more electrical, data and fluid line connections for the new Port One (P1) truss segment, install a second wireless video antenna system and move a Crew Equipment Translation Aid railway handcar from the P1 to the S1 truss. P1 was installed just before the Tuesday spacewalk. Thursday's and Saturday's spacewalks each will last about 61/2 hours.
Thanksgiving travel is being taken to new heights by Endeavour and ISS crewmembers. They will log about 1.68 million miles during the four-day weekend, with no weather or traffic delays, no airport security problems and certainly no crowds. Their vehicles' mileage over just those four days is excellent -- almost unlimited. Lopez-Alegria and Herrington are scheduled to travel about 227,500 Thanksgiving weekend miles outside the ISS-Endeavour complex during their two spacewalks.
