USERS is a reusable spacecraft being developed by Japan's Ministry of International Trade and Industry, the Organization for Development of New Energy and Industrial Technologies, and the Institute for Unmanned Space Experiment Free Flyer (USEF).USERS is intended to support applications of the space environment. The spacecraft will consist of two major components, a reentry module (REM) and a service module (SEM). The REM will contain an electric furnace for experimental production ofsuperconductmg materials and will return to earth after the conclusion these experiments. The SEM will provide electricity and other resources to the REM and will house its own experimental equipment. The SEM will be used to develop a multipurpose compact satellite bus capable of applications in high, medium and low orbits.
