Reactionless Space Drive Being Tested
IO9 ^ | April 30, 2015 | George Dvorsky

"Last year, NASA’s advanced propulsion research wing made headlines by announcing the successful test of a physics-defying electromagnetic drive, or EM drive. Now, this futuristic engine, which could in theory propel objects to near-relativistic speeds, has been shown to work inside a space-like vacuum.

NASA Eagleworks made the announcement quite unassumingly via NASASpaceFlight.com. There’s also a major discussion going on about the engine and the physics that drives it at the site’s forum."

... "The NASASpaceflight.com group has given consideration to whether the experimental measurements of thrust force were the result of an artifact. Despite considerable effort within the NASASpaceflight.com forum to dismiss the reported thrust as an artifact, the EM Drive results have yet to be falsified.

After consistent reports of thrust measurements from EM Drive experiments in the US, UK, and China – at thrust levels several thousand times in excess of a photon rocket, and now under hard vacuum conditions – the question of where the thrust is coming from deserves serious inquiry."

Most of technology had no scientific explanation for “why it works” for most of history.

I find it interesting that it’s termed an “artifact”...
Could there be such a thing?
Yes, there could...que guy with crazy hair.

Depends on whose military - I'm assuming it would be the US, Japan, UK, France, China, ROK, Israel and maybe Germany. I don't believe Russia will be a player in 20 years.

In any event, nobody will be allowed to move asteroids into Earth orbit except under military control. Lunar LaGrange orbit is a possible exception.

You think full military control would make them safer?

More like a 200kt ship at 0.01c which would be bad enough.
