Astronauts and cosmonauts on board Atlantis and the International Space Station spent today transferring supplies and hardware, and preparing for Monday's third and final spacewalk of the mission.

The Expedition Five crewmembers will spend several hours today working on the International Space Station's treadmill exercise machine. They will replace the Treadmill Vibration Isolation System, or TVIS, which malfunctioned in July.

The joint crews of Space Shuttle Atlantis and the International Space Station will transfer supplies and equipment between the two spacecraft today and also prepare for the final spacewalk of the mission.

Astronauts Dave Wolf and Piers Sellers moved smoothly and ahead of schedule through their second spacewalk of the week today, continuing to bring the International Space Station's newest component to life and installing devices to prevent future difficulties with station cooling connections.

Focus of attention aboard Space Shuttle Atlantis and the International Space Station once again is outside the complex as Astronauts Dave Wolf and Piers Sellers conduct the second of three planned spacewalks to bring the station's newest component – the Starboard 1 (S1) Truss – to life.

After a very busy day Thursday, the combined shuttle and space station crew took several hours of off-duty time today, and then began transfer operations between the vehicles and preparations for the second of the mission's three spacewalks scheduled to begin at 9:41 a.m. Saturday.

EXP 5 CREW STATUS REPORT - Crews to Transfer Supplies

The STS-112 and Expedition Five crews will spend part of today transferring equipment and supplies from Space Shuttle Atlantis to the International Space Station.

With a major milestone of the STS-112 mission behind them, Space Shuttle Atlantis and International Space Station crewmembers will have a quieter day today. Following some time off to relax, the joint crews later will begin transferring equipment and supplies to the orbiting laboratory.

Astronauts Dave Wolf and Piers Sellers completed all planned International Space Station assembly tasks today during a 7-hour, 1-minute spacewalk, an excursion focused on attaching the next segment of the station's backbone – the Starboard One (S1) Truss – to the Starboard Zero (S0) Truss.
