Backdropped by a blue and white Earth, the International Space Station is seen from Space Shuttle Discovery as the two spacecraft begin their relative separation. Earlier the STS-120 and Expedition 16 crews concluded 11 days of cooperative work onboard the shuttle and station. Undocking of the two spacecraft occurred at 4:32 a.m. (CST) on Nov. 5, 2007.
