International Space Station (ISS)

Back dropped by the blackness of space and Earth's horizon is the International Space Station (ISS) as seen from Space Shuttle Discovery as the two spacecraft begin their relative separation. The latest configuration of the ISS includes the Italian-built U.S. Node 2, named Harmony, and the P6 truss segment installed over 11 days of cooperative work onboard the shuttle and station by the STS-120 and Expedition 16 crews. Undocking of the two spacecraft occurred at 4:32 a.m. (CST) on Nov. 5, 2007.
