(09/18/1998) -- The International Extreme Ultraviolet Hitchhiker (IEH-3), one of the payloads for the STS-95 mission, is suspended above its payload canister in the Multi-Payload Processing Facility. The mission is scheduled for liftoff on Space Shuttle Discovery on Oct. 29. 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. Other research payloads include the Hubble Space Telescope Orbital Systems Test Platform, the Spartan solar-observing deployable spacecraft, and the SPACEHAB single module with experiments on space flight and the aging process
