Technicians Replace Leak Source; Arm Evaluation Continues The source of the oxygen leak that delayed the launch of STS-113 on Sunday - a faulty flex hose assembly - has been successfully replaced inside Space Shuttle Endeavour. The new assembly and Endeavour's bulkhead have been tested, X-rayed and cleared for flight. Meanwhile, evaluation continues of the damage that Endeavour's robot arm sustained during the leak troubleshooting efforts. A team of robot arm experts arrived at Kennedy Space Center, Fla., Wednesday and are planning to perform ultrasound testing of the arm. Program managers are scheduled to meet Friday to discuss the results of the tests and analysis. The robot arm will be used to lift the P1 (P-One) Truss out of the payload bay and hand it to its station counterpart, Canadarm2. STS-113 is currently scheduled to lift off no earlier than 6-10 p.m. CST Monday (0000-0400 GMT Tuesday). International Space Station Status Report #02-52 4 p.m. CST, Friday, Nov. 15, 2002 Expedition Five Crew The Expedition 5 crewmembers - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - spent their 23rd week in space continuing preparations for the arrival of their replacements, the Expedition 6 crew. 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. Information on the crew's activities, future launch dates, as well as station sighting opportunities from anywhere on the Earth, is available on the Internet at: http://spaceflight.nasa.gov Details on station science operations can be found on an Internet site administered by the Payload Operations Center at NASA's Marshall Space Flight Center in Huntsville, Ala., at: http://scipoc.msfc.nasa.gov The next ISS status report will be incorporated into the first STS-113 mission status report beginning after the launch of Endeavour, or sooner, if developments warrant.
