International Space Station (ISS)

This is a crew portrait of the International Space Station (ISS) Expedition Four. Left to right are Astronaut Daniel W. Bursch, flight engineer; Cosmonaut Yuri I. Onufrienko, mission commander; and Astronaut Carl E. Walz, flight engineer. The crew was launched on December 5, 2001 aboard the STS-108 mission Space Shuttle Orbiter Endeavour, the 12th Shuttle mission to visit the ISS. The crew returned to Earth on June 19th, 2002 aboard the STS-111 mission Space Shuttle Orbiter Endeavour, replaced by Expedition Five. The Expedition Four crew spent 196 days in space, which gives flight engineers Walz and Bursh the U.S. space flight endurance record.
