The open doors of the payload bay on Space Shuttle Discovery await the transfer of four of the payloads on mission STS-95: the SPACEHAB single module, Spartan, the Hubble Space Telescope Orbiting Systems Test Platform (HOST), and the International Extreme Ultraviolet Hitchhiker (IEH-3). At the top of bay are the airlock (used for depressurization and repressurization during extravehicular activity and transfer to Mir) and the tunnel adapter (enables the flight crew members to transfer from the pressurized middeck crew compartment to Spacelab's pressurized shirt-sleeve environment). SPACEHAB involves experiments on space flight and the aging process. Spartan is a solar physics spacecraft designed to perform remote sensing of the hot outer layers of the sun's atmosphere or corona. HOST carries four experiments to validate components planned for installation during the third Hubble Space Telescope servicing mission and to evaluate new technologies in an Earth-orbiting environment. IEH-3 comprises several experiments that will study the Jovian planetary system, hot stars, planetary and reflection nebulae, other stellar objects and their environments through remote observation of EUV/FUV emissions; study spacecraft interactions, Shuttle glow, thruster firings, and contamination; and measure the solar constant and identify variations in the value during a solar cycle. Discovery is scheduled to launch on Oct. 29, 1998
