STS088-307-036 (4-15 December 1998) --- Cosmonaut Sergei K. Krikalev, mission specialist, uses a bicycle ergometer to exercise his upper body on the busy middeck of the Earth-orbiting Space Shuttle Endeavour. Krikalev, named recently to serve on the first International Space Station (ISS) crew, is representing the Russian Space Agency (RSA). After devoting the major portion of its mission time to various tasks to ready the Russian-built FGB Module (Zarya) and the docked United States-built Unity Module (Node 1), the six-member crew released the tandem toward mission’s end.
