STS-123 Crew Patch

STS-123, International Space Station (ISS) Assembly Flight 1J/A, is the 25th flight to the station. The crew consists of Commander Dominic L. Gorie, Pilot Gregory H. Johnson, and Mission Specialists Richard M. Linnehan, Robert L. Behnken, Michael J. Foreman and Japan Aerospace Exploration Agency Astronaut Takao Doi.

The STS-123 shuttle mission will deliver the Japanese Kibo Logistics Module and the Canadian Dextre robotics system to the International Space Station. The mission will deliver NASA Astronaut Garrett Reisman to the complex and return European Space Agency Astronaut Léopold Eyharts to Earth.

Several Detailed Supplementary Objectives (DSOs) and Supplemental Medical Objectives (SMOs) will also be flown during the STS-123 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:

  • Sleep-Wake Actigraphy and Light Exposure During Spaceflight (DSO 634)
  • Space Flight Induced Reactivation of Epstein-Barr Virus (98-E129)
  • Validation of Procedures for Monitoring Crewmember Immune Function (SMO 015)

This flight will be the orbiter's 21st mission and the 122nd in the Shuttle program's history.
