A year ago when I came to know about NASA’s impossible space engine, I was little convinced by the idea of an engine that would violate the laws of physics. This revolutionary space engine doesn’t require any rocket fuel to travel infinite distances. The group of NASA scientists working on it have been trying to figure out for months and now they have released new tests results.
The researchers at NASA’s Johnson Space Centre have successfully tested the Electromagnetic (EM) propulsion drive in vacuum conditions. The thrust measurements of this EM propulsion drive defy the classical physics laws of the conservation of momentum.
In the EM Drive, the microwaves are produced within a container using electricity and they are bound to bounce in that specially designed container. The classical physics laws expect them to be unusable, but this bouncing creates a difference in radiation pressure and thus results in thrust generation in the impossible space engine.
The concept of EM Drive came into existence when back in 2001, Satellite Propulsion Research Ltd (SPR), a small UK company started a research and development program. According to SPR, the microwave cavities could help in the direct conversion of electrical energy to thrust without any propellant. In the start, the scientific community rejected this idea as the lack of propulsion would mean that there won’t be anything to counter-balance the change in the momentum of the spacecraft while accelerating.
Now the tests were conducted in vacuum to rule out the possibility that EM Drive could have been working due to heat transfer from the outside. Now the idea that the force is being generated by bouncing EM waves inside the chamber with some energy transferred to a reflector for producing thrust.
NASA wants to conduct more tests in future on EM Drives in the vacuum. The work isn’t done yet and a lot of hard work is needed to verify that a working Impossible Engine is possible.
