Satellites powered by solid metal could one day use space junk for fuel

Magdrive is working on three versions of its space thrusters, and because they run on solid metal, they might one day even be powered by space junk collected directly in orbit, turning it from threat to fuel source.
The article from CNN discusses a groundbreaking propulsion technology known as the "Magdrive," developed by a company called Magdrive. This innovative system uses solid metal propellant, specifically magnesium, which is ignited to produce thrust. Unlike traditional chemical rockets that rely on liquid or gaseous propellants, the Magdrive's solid metal approach offers several advantages: it's safer, more environmentally friendly, and potentially more cost-effective. The technology has been tested in space, with a successful demonstration on a satellite launched in January 2023. The Magdrive could revolutionize satellite propulsion by providing a simpler, more reliable, and less hazardous method for maneuvering in space, potentially extending the operational life of satellites and reducing the need for frequent refueling missions. This could lead to more sustainable space operations and open up new possibilities for space exploration and satellite management.
