During the week, Expedition 5 packed, checked and labeled experiment racks, and did a dry run of the installation of the Port One (P1) truss segment onto the ISS using the Canadarm2. The crew also performed maintenance on the VOA (volatile organics analyzer), which looks for volatile organic compounds in the station's atmosphere, and replaced a cable on the station's treadmill. They also set up the EarthKam equipment to give over 2,000 students and teachers across the U.S. and Japan a chance to take pictures of the Earth using a remotely controlled camera aboard the station. Whitson deactivated the camera Friday, but Expedition 6 will reactivate it for use during its mission.
The space shuttle Endeavour will deliver the Expedition 6 crew, along with the P1 truss, to the station during the STS-113 mission. The P1 will be the third segment of the station's integrated truss system to be launched this year. Part of the station's backbone, it is one of 11 such truss segments that will support cooling radiators power-producing solar arrays and a railroad on which the Canadarm2 can move.
Preparations continue for the launch next week of Endeavour to the ISS next week.
