The Tethered Satellite System is a space technology that involves a satellite connected to a larger spacecraft by a long cable or tether. This tether allows the satellite to maintain its position relative to the spacecraft while also enabling various scientific experiments and data collection. The system can generate power through the motion of the satellite in Earth's magnetic field. One of the key benefits of the Tethered Satellite System is its ability to provide stability and control for the satellite. It can also facilitate communication between the satellite and the spacecraft, enhancing the overall efficiency of space missions. This technology has been explored in various missions, including those by NASA and ESA.
