ISS024-E-015199 (23 Sept. 2010) --- Russian cosmonaut Alexander Skvortsov, Expedition 24 commander; and NASA astronaut Tracy Caldwell Dyson, flight engineer, make final preparations for their departure in the Soyuz TMA-18 docked to the Poisk Mini-Research Module 2 (MRM2) of the International Space Station. The Soyuz undocked at 10:02 p.m. (EDT) on Sept. 24, 2010, carrying Skvortsov and Caldwell Dyson, along with Russian cosmonaut Mikhail Kornienko (out of frame). 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.
