Carried the IEH-1 (International EUV Hitchhiker) built by the Smithsonian Astrophysical Observatory. This includes a solar EUV telescope (SEH), and an Italian-US EUV telescope, UVSTAR, which will observe a variety of astronomical targets in the 500-1250A range. Prime target for this mission is Io plasma torus around Jupiter. Comet 6P/D'Arrest, currently near perihelion, may also be observed. UVSTAR has two 0.3 m telescopes.
The spacecraft also carried the GLO-3 airglow experiment in a canister and the CONCAP materials processing experiment in another canister.
