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