Zenno Astronautics wants to move spacecraft around using electromagnets, not fuel  

By Editor - Fri Aug 05, 6:03 am

It’s easy to think about satellites as a bunch of mini-moons, orbiting the Earth seamlessly and without any (noticeable) movement. But that’s not quite right: satellites and other spacecraft often require fairly continuous tweaks to their positions in orbit. Historically, the aerospace industry has relied on thrusters, or a combination of reaction wheels and magnetic torque rods, to control a spacecraft’s attitude, control and positioning. But these take up a lot of space and mass, and limit how long a spacecraft can stay in orbit. New Zealand-based Zenno Astronautics has come up with an alternative to these heavy and time-limited propulsion systems
