Backdropped by Earth's horizon and the blackness of space, the International Space Station is seen from Space Shuttle Endeavour as the two spacecraft begin their relative separation. Earlier the STS-123 and Expedition 16 crews concluded 12 days of cooperative work onboard the shuttle and station. Undocking of the two spacecraft occurred at 7:25 p.m. (CDT) on March 24, 2008. ESA astronaut Léopold Eyharts returned to Earth with STS-123 at the end of his stay on the ISS.
