ISS024-E-015402 (24 Sept. 2010) --- Russian cosmonaut Fyodor Yurchikhin, Expedition 24/25 flight engineer, closes the hatch between the International Space Station and the Soyuz TMA-18 spacecraft as three Expedition 24 crew members prepare to depart from the space station. Undocking occurred at 10:02 p.m. (EDT) on Sept. 24, 2010, carrying Russian cosmonaut Alexander Skvortsov, Soyuz commander and Expedition 24 commander; along with NASA astronaut Tracy Caldwell Dyson and Russian cosmonaut Mikhail Kornienko, both flight engineers. Originally scheduled for Sept. 23, the Soyuz undocked a day later due to a Poisk-side hatch sensor problem, which prevented hooks on the Poisk side of the docking interface from opening.
