A while back, I wrote about a very exciting if baffling new space propulsion system: the EmDrive. It's a space propulsion system that doesn't appear to use any propellant, maybe violates the known ...

The IVO quantum inertia drive is in orbit now and will be turned on within one to ten weeks and then operated for many weeks or months. The IVO quantum inertia drive is very controversial because it ...

NASA’s controversial EmDrive is a curious development. A reactionless propulsion drive that, by all known laws of physics, shouldn’t work, but it does. Despite successful tests, a number of physicists ...

A new theory of inertia could explain how NASA is generating thrust with a new drive design, and may even show them how to make it more powerful. Share on Facebook (opens in a new window) Share on X ...

Radiation detection company US Nuclear Corp is trying to woo NASA into signing a contract to develop a fusion-powered spacecraft propulsion system that could take future space travelers all the way to ...
