A NASA/GSFC Shuttle Small Payloads Project Hitchhiker Payload
The International Extreme Ultraviolet Hitchhiker Payload (IEH-1) is the first of five planned flights to investigate the uncertainty of, and long term variation in, the magnitude of the absolute solar extreme ultraviolet (EUV) flux and to study the EUV emissions of the Jupiter Io plasma torus system. The IEH-1 Italian Space Agency partners will study the EUV emission of hot stellar objects. These observations are accomplished by the Solar Extreme Ultraviolet Hitchhihker (SEH) and Ultraviolet Spectrograph Telescope for Astronomical Research (UVSTAR). Both of these experiments are sponsored by NASA HQ Code SLC.
Hitching a ride with the IEH-1 is the Shuttle Glow (GLO) experiment sponsored by NASA HQ Code SS and the Consortium for materials development in space Complex Autonomous Payload #4 (CONCAP IV-03) experiment sponsored by NASA HQ Code OACT.
The STS-69 Logo
The IEH-1 is scheduled to launch aboard Endeavor this July 20th, 1995. The astronauts for STS-69 are: Dave Walker, Ken Cockrell, Jim Voss, Jim Newman and Michael Gernhardt. The crew will support IEH-1 activities by activating the payload and performing attitude maneuvers in support of UVSTAR, SEH and GLO-3 observations. While most of the payload activites will be controlled via the Goddard Control Center, the crew will be interfacing with the CONCAP IV-03 experiment via the PGSC laptop computer, i.e. sending commands and relaying telemetry to the GSFC control center.

The Goddard Space Flight Center's (GSFC) Shuttle Small Payloads Project (SSPP) has responsibility for the mission management, safety, payload integration and mission operations of the IEH-1 payload. IEH-1 represents the second of five planned SSPP Hitchhiker payloads manifested to fly this year. For more information on the SSPP manifested payloads, click here.
Planned to launch aboard the orbiter Endeavor this July 20th 1995, IEH-1continues the SSPP tradition of flying faster, better, cheaper payloads aboard NASA's space shuttle. During the 11 day mission, science data collected from the IEH-1 payload, shown above during Integration and Test at GSFC, will be posted on this World Wide Web home page.
