ISS010-E-11990 (22 December 2004) --- Backdropped by a blanket of clouds, an unpiloted Progress 15 supply vehicle departs from the International Space Station (ISS) at 1:37 pm (CST) on December 22, 2004, carrying its load of trash and unneeded equipment to be deorbited and burned up in Earth�s atmosphere. The undocking clears the way for the arrival of a new Progress 16, planned to launch December 23 and dock with the Station on December 25.
