Improbable space engine rockets past peer review

Long thought to be nothing more than a space dream, the EmDrive, a rocket propulsion technology that requires no propellant, has cleared peer review, the International Business Times reports. The new engine, first proposed 17 years ago, relies on microwaves for its thrust, which are fired into a metal cone, causing acceleration. The latest design, which will be published in the Journal of Propulsion, was the brainchild of scientists at NASA’s experimental lab, Eagleworks Laboratories. Although EmDrive propulsion technology has been the target of criticism from academics and armchair scientists alike, if it works, it could significantly speed space travel.
