Ever since NASA announced that they had created a prototype of the controversial Radio Frequency Resonant Cavity Thruster (aka. the EM Drive), any and all reported results have been the subject of controversy. Initially, any reported tests were the stuff of rumors and leaks, the results were treated with understandable skepticism. Even after the paper submitted by the Eagleworks team passed peer review, there have still been unanswered questions.

Hoping to address this, a team of physicists from TU Dresden – known as the SpaceDrive Project – recently conducted an independent test of the EM Drive. Their findings were presented at the 2018 Aeronautics and Astronautics Association of France’s Space Propulsion conference, and were less than encouraging. What they found, in a nutshell, was that much of the EM’s thrust could attributable to outside factors.

The results of their test were reported in a study titled “The SpaceDrive Project – First Results on EMDrive and Mach-Effect Thrusters“, which recently appeared online. The study was led by Martin Tajmar, an engineer from the Institute of Aerospace Engineering at TU Dresden, and included TU Dresden scientists Matthias Kößling, Marcel Weikert and Maxime Monette.

EM - Drive - Concept - Space - Engine

To recap, the EM Drive is a concept for an experimental space engine that came to the attention of the space community years ago. It consists of a hollow cone made of copper or other materials that reflects microwaves between opposite walls of the cavity in order to generate thrust. Unfortunately, this drive system is based on principles that violate the Conservation of Momentum law.

This law states that within a system, the amount of momentum remains constant and is neither created nor destroyed, but only changes through the action of forces. Since the EM Drive involves electromagnetic microwave...
