NASA's EM Drive will be tested in space sometime in the next six months, according to reports published Tuesday by ScienceAlert. An EM Drive will be launched into space aboard a small satellite. The drive will be launched into a decaying orbit, which it can only maintain if it functions properly. The EM Drive is extremely contentious among scientists, since it allegedly uses exotic physics to violate Newton's Third Law and the law of conservation of momentum. A NASA scientist confirmed online late last month that the Em Drive "warp drive" has passed peer-review; NASA itself has not yet confirmed the test results. A Finnish team recently published a peer-reviewed paper proposing that an EM Drive could work by generating unseen exhaust which would still carry momentum. "People all around the world have been measuring thrust. You've got guys building them in their garages and very large organisations building cavities too," Roger Shawyer, the British scientist who first proposed the
