Expedition 15 conducts emergency exit drill

The Expedition 15 crew members conducted a mandatory emergency exit drill Tuesday to simulate their response to a rapid depressurization of the station.

Russian and U.S. specialists were standing by at both control centers for questions and comments. During the drill, the group proceeded through a series of checkpoints, determining and verifying various settings, measurements and configurations.

They stepped through the process of preparing the ISS Progress 24 cargo ship for undocking and moved along the emergency exit path toward the docked Soyuz TMA-10 spacecraft.
