Top priorities for the 11-day STS-108 (UF-1) mission of Endeavour are rotation of the International Space Station Expedition 3 and Expedition 4 crews; bringing water, equipment and supplies to the station in the Multi-Purpose Logistics Module Raffaello; and the crew's completion of robotics tasks and a spacewalk to install thermal blankets over two pieces of equipment at the bases of the Space Station's solar wings. The three-member Expedition 3 crew will be returning to Earth aboard Endeavour after a five-month stay on the Station.
