Inside the air lock in the Space Station Processing Facility, a technician points out equipment to cosmonaut Yury Usachev (right), who is part of the Expedition Two crew going to the International Space Station. Usachev and other crew members astronauts Susan Helms and James 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
