From the left are astronauts Thomas Reiter of the European Space Agency, Michael E. Fossum, Piers J. Sellers, Steven W. Lindsey, Mark E. Kelly, Stephanie D. Wilson and Lisa M. Nowak. Lindsey is mission commander and Kelly is pilot, with the other five serving as mission specialists. Once onboard the International Space Station, Reiter, who flew for six months on the Russian space station Mir, will become the first non-American or non-Russian long-duration crewmember on the Station. Joining the Expedition 13 crew, he will fly under a commercial agreement between ESA and Roscosmos.
