WebIn January 1998, a segment of the MIR solar array was retrieved by the space shuttle. The segment, composed of eight panels, spent 10.5 years in a 380 km orbit. The panel design is exclusive; a laminated sandwich of cover glass, glass cloth, silicon solar cells (11% efficiency), glass cloth and optical solar reflectors (OSRs) [97].Two postflight … An optical solar reflector (OSR) is a component of a vehicle or machine designed to fly in outer space. The reflector consists of a top layer made out of quartz, over a reflecting layer made of metal. OSRs are used for radiators on spacecraft. The quartz outer layer lets the solar light through which reflects on the metal layer. This results in a low absorption coefficient. The quartz layer is a good IR emitter. The result of these properties is … WebMETA-REFLECTOR aims at developing a radically new technology to produce Optical Solar Reflectors (OSRs) and to govern the thermo-optical properties of the interface between the spacecraft and the space environment.
