Propulsion-Free Space Travel

2026-04-15T01:14:24.000Z Space travel has always depended on one thing: fuel. Carry it, burn it, run out of it. But what if propulsion didn’t need fuel at all? Researchers are rethinking how spacecraft move. Some are using lasers to push ultralight graphene through space. Others are exploring beams of high-speed electrons to generate thrust. There are even early systems designed to move satellites or debris using electrostatic forces—without ever making physical contact.
