Zenno Astronautics

Zenno Astronautics is the space superconductor company, developing the most powerful magnetic technologies for spacecraft and orbital infrastructure. Their flagship Supertorquer product provides fuel-free attitude control using superconducting magnetic actuators, replacing traditional reaction wheels and magnetic torque rods. Zenno's systems enable jitter-free pointing windows of 3–6 hours, support spacecraft from 50 kg to space station scale, and achieved the world's first in-space operation of a superconducting magnetic actuator in 2026. The company develops electromagnetic launch systems, radiation shielding, and other superconducting platforms for defense, transportation, and industrial activity in space, with contracts signed with Mitsubishi Electric and a partnership with Portal Space Systems.
