Expedition 10 Commander Leroy Chiao trains in the waters of the Neutral Buoyancy Laboratory (NBL) at NASA's Johnson Space Centre in Houston. Chiao and Expedition 10 Flight Engineer Salizhan Sharipov used the lab to help prepare them for work on the exterior of the International Space Station. Chaio and Sharipov blasted off from Kazakhstan on a Russian Soyuz spacecraft on 13 October 2004. Russian Cosmonaut Yuri Shargin travelled with them. They returned to Earth several days later with Expedition 9 crewmembers Mike Fincke and Gennady Padalka.
