Cosmonaut Yuri I. Malenchenko, Expedition Seven mission commander, works with Extravehicular Mobility Unit (EMU) spacesuits in the Quest airlock on the International Space Station (ISS). Today Malenchenko and astronaut Edward T. Lu (out of frame), NASA ISS science officer and flight engineer, performed an EMU spacesuit fit check and don/doff dry-run. The objective was to check out the equipment and provide the crew with training for preparing for a two-person spacewalk without intravehicular (IV) crewmember support, should it become necessary. Malenchenko represents Rosaviakosmos.
