Inside the air lock in the Space Station Processing Facility, the Expedition Two crew look at equipment. Seen from left are cosmonaut Yury Usachev, a technician, and astronauts Susan Helms and James Voss. At far right is astronaut John Young, who flew on mission STS-1. Usachev, Helms and Voss will be flying on mission STS-102, launching March 8. The air lock will be carried to the Station during their tenure in space. STS-102 will be Helms’ and Voss’s fifth Shuttle flight, and Usachev’s second. They will be replacing the Expedition One crew (Bill Shepherd, Yuri Gidzenko and Sergei Krikalev), who will return to Earth March 20 on Discovery along with the STS-102 crew
