Ferrofluids: The Strangest Idea Ever For A Spacecraft Propulsion System

When it comes to the future of space exploration, some truly interesting concepts are being developed. Hoping to reach farther and reduce associated costs, one of the overarching goals is to find more fuel-efficient and effective means of sending robotic spacecraft, satellites and even crewed missions to their destinations. Towards this end, ideas like nuclear propulsion, ion engines and even antimatter are all being considered.
But this idea has to be the strangest one to date! It’s known as a ferrofluid thruster, a new concept that relies on ionic fluids that become strongly magnetized and release ions when exposed to a magnetic field. According to a new study produced by researchers from the Ion Space Propulsion Laboratory at Michigan Tech, this concept could very well be the future of satellite propulsion…
