(05/17/2002) -- During Terminal Countdown Demonstration Test activities at Launch Pad 39A, the Expedition 5 and STS-111 crews pose on the 295-foot level. Standing, left to right, are Pilot Paul Lockhart, and the Expedition 5 crew Peggy Whitson, Commander Valeri Korzun and Sergei Treschev. Kneeling in front are Mission Specialist Philippe Perrin, Commander Kenneth Cockrell and Mission Specialist Franklin Chang-Diaz. Korzun and Treschev are with the Russian Space Agency, and Perrin is with the French Space Agency. Seen behind the crews are the top of the orange external tank and one of the white solid rocket boosters. The TCDT includes emergency egress training at the pad and a simulated launch countdown. Mission STS-111 is known as Utilization Flight 2, carrying supplies and equipment in the Multi-Purpose Logistics Module Leonardo to the International Space Station. The payload also includes the Mobile Base System, which will be installed on the Mobile Transporter to complete the Canadian Mobile Servicing System, or MSS, and a replacement wrist/roll joint for Canadarm 2. The mechanical arm will then have the capability to 'inchworm' from the U.S. Lab Destiny to the MSS and travel along the truss to work sites. Expedition 5 will travel to the Station on Endeavour as the replacement crew for Expedition 4, who will return to Earth aboard the orbiter. Launch is scheduled for May 30, 2002
