STS-122 Crew Patch

STS-122, International Space Station (ISS) Assembly Flight 1E, is the 24th flight to the station. The crew consists of Commander Stephen N. Frick, Pilot Alan G. Poindexter, and Mission Specialists Rex J. Walheim, Stanley G. Love, Leland D. Melvin and European Space Agency astronaut Hans Schlegel.

The STS-122 shuttle mission will deliver the European Space Agency's Columbus Laboratory to the International Space Station. Expedition Sixteen Flight Engineer Daniel Tani, brought to the space station on the STS-120 mission, will return home with the STS-122 crew. STS-122 will deliver European Space Agency Astronaut Léopold Eyharts to the complex to replace him.

Several Detailed Supplementary Objectives (DSOs) and Supplemental Medical Objectives (SMOs) will also be flown during the STS-122 mission. DSOs and SMOs are space and life sciences investigations. Their purpose is to determine the extent of physiological deconditioning resulting from space flight, test countermeasures to those changes, and characterize the environment of the Space Shuttle and/or space station relative to crew health. Experiments being performed during this mission are:

  • Bioavailability and Performance Effects of Promethazine During Space Flight (DSO 490)
  • Sleep-Wake Actigraphy and Light Exposure During Spaceflight (DSO 634)
  • Test of Midodrine as a Countermeasure Against Postflight Orthostatic Hypotension (SMO 006)
  • Validation of Procedures for Monitoring Crewmember Immune Function (SMO 015)

Space Shuttle Atlantis STS-122 is scheduled to last 11 days. This flight will be the orbiter's 29th mission and the 121st in the Shuttle program's history.
