The Fuel-Free Thruster Nobody’s Talking About Just Changed Space Travel Forever
A superconducting thruster just generated thrust in orbit without burning a single gram of propellant โ by riding Earth’s magnetic field like a surfer rides a wave. It’s not warp drive, and it won’t take you to Mars. But it attacks the single most expensive constraint in satellite design: fuel. If this scales, the economics of low Earth orbit change fundamentally.
