Japanese materials science satellite. USERS (Unmanned Space Experiment Recovery System) was a Japanese microgravity experimental satellite. Micro gravity and return satellite built by Mitsubishi Electric (MELCO) for Institute for Unmanned Space Experiment Free Flyer (USEF), Japan. Launched 2002.
The 1.7-ton (with fuel), 700-W satellite consisted of a ReEntry Module (REM) and a Service Module (SEM) that was to provide power and a communications link to the REM. In turn, REM consisted of a ReEntry Vehicle (REV) and a Propulsion Module (PM). After 8.5 months in orbit, REM was to be separated to deorbit and the REV was to soft-land with its contents at 151E 22N in the Pacific near Japan's Ogasawara Islands. The SEM was to be elevated to a higher orbit.
The SEM had a mass of 800 kg; the REV/PM had a total mass of 926 kg
