Mission objectives

The International Space Station expanded its science investigations, almost doubling the previous amount of experiments performed during the Expedition Four mission. The fourth resident crew launched on 5 December 2001 on board Space Shuttle Endeavour during mission STS-108. They became official station residents at 20:03 UTC on 7 December 2001, and remained on board until June 2002, when they landed on STS-111.
