NASA researchers have reported fresh evidence that an “impossible” space propulsion technology might actually work.
A study from NASA’s Johnson Space Center in Houston says a microwave thruster system that requires no propellant appears to generate a tiny amount of thrust. If the technology pans out, it could make spaceflight far cheaper and speedier, advocates say. They argue that the thruster harnesses subatomic particles that pop into and out of existence in accordance with quantum physics — a hypothesis that’s mentioned in the study.
