Well, it turns out this crazy EM drive...which we still have no idea how it works...also works in a vacuum, meaning it will work in space. It's like a real-life Impulse engine from Star Trek! They're even saying it could potentially propel spacecraft at near relativistic speeds. Cool

Moving out from LEO, Mr. March, from NASA EagleWorks, noted that a spacecraft equipped with EM drive technology could surpass the performance expectations of the WarpStar-I concept vehicle.
If such a similar vehicle were equipped with an EM Drive, it could enable travel from the surface of Earth to the surface of the moon within four hours.
