(05/28/2002) - During suit check, part of pre-launch activities, Expedition 5 Commander Valeri Korzun gets help with his helmet. Korzun is with the Russian Space Agency. Part of Mission STS-111, Expedition 5 will travel to the International Space Station on Space Shuttle Endeavour as the replacement crew for Expedition 4, who will return to Earth aboard the orbiter. The mission, known as Utilization Flight 2, is carrying supplies and equipment to the Station. The payload includes the Multi-Purpose Logistics Module Leonardo, 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. Launch is scheduled for May 30, 2002
