Zenno Astronautics successfully tested its "Supertorquer" system in orbit. This shoebox-sized device utilizes superconducting magnets and solar power to control satellites without propellant. The technology works by generating a magnetic field that interacts with Earth's magnetic field. By controlling this induced field, the satellite's orientation can be precisely managed. Superconducting magnets require extremely low temperatures to function but can generate significant magnetic forces. The Supertorquer system is insulated and uses a heat pump to maintain these low temperatures. Solar panels charge a battery that powers the superconducting coils when needed. This process converts solar energy directly into useful work for satellite maneuvering. Zenno Astronautics aims to develop larger systems for fuel-free satellite docking and proximity operations. Future plans include using these magnets for deep-space missions, like journeys to the Moon and Mars.
