Satellite of the Day
TUBSAT-A
TUBSAT-A is a small box-shaped satellite operated by TUB (Technische Universität Berlin) and launched on January 25, 1994, aboard a Tsiklon-3 rocket from Plesetsk Cosmodrome. Weighing just 40 kilograms, this compact spacecraft exemplifies the early era of university-built microsatellites and represented an ambitious educational and research initiative for German space science.
Orbiting at a high inclination of 82.57 degrees, TUBSAT-A was designed to conduct Earth observation and technology demonstration experiments. Its near-polar orbit provided excellent coverage of high-latitude regions and made it a valuable platform for testing innovative satellite subsystems. As part of the broader TUBSAT program, this mission contributed valuable lessons to the growing field of small satellite design and operations that would influence CubeSat and other miniaturized spacecraft programs for decades to come.
