It's really starting to look as if an "impossible" space propulsion technology actually works. Researchers at NASA's Johnson Space Center in Houston have found that a microwave thruster system that requires no propellant does indeed generate a small amount of thrust, Wired UK reported last week. If the technology pans out, it could make spaceflight far cheaper and speedier, potentially opening up much of the cosmos to exploration, advocates say. The thruster may work by somehow harnessing the subatomic particles that continuously pop into and out of existence, the NASA researchers suggest. The results and the technology are promising enough to warrant further study, they wrote in the study.
