According to the exposed NASA document, NASA is developing a fuel-efficient engine called the EM Drive that does not require constant Rocket fuel or nuclear reactors and is expected to send humans to Mars in as little as 10 weeks. According to the laws of physics, the development of such an engine is one "Impossible Mission," a series of successful tests conducted by the NASA Johnson Space Center seem to indicate that EM Drive is more connected to reality Near No fuel engine into the development of Mars tour in just 10 weeks Traditional rocket engines use chemical fuels and complete the combustion and injection of fuel in thrusters. In a space-thin, near-vacuum environment, Newton's third law of motion played a role: by ejecting matter into the vacuum of space

Health thrust, no air. But EM Drive does not need to inject fuel. By design, the use of light particles and the reflection of microwaves within the conically closed chamber can be done in a thin The long end produces thrust, driving the engine forward. The document was first exposed by Australian user Phil Wilson at the NASA Space Forum but was later removed by the administrator. Subsequent technical media NextBigFuture released the document content, describes the early test that this propulsion system accepts in vacuum.
The team of engineers conducted tests at 40 watts, 60 watts and 80 watts, respectively. The results showed that the thrust achieved by this propulsion system in a vacuum was similar to that at Air performance.
The test resulted in a power of 1.2 millinewtons per kilowatt (mN / Kw). And the most advanced Hall thruster can achieve 60 milliwatts / kilowatt at present power.
But researchers said that the need to consume fuel can make up for lack of motivation.
No fuel engine into the development of Mars tour in just 10 weeks Despite the success of NASA's testing, there is no sign that the document has passed peer review (this is one of the key processes in the scientific research process) , The document has not published in the magazine. It is reported that a number of research and development teams are working on this technology, including NASA's Eagleworks Laboratory, which is developing advanced Propulsion system.
Earlier this year, inventor Roger Shaw filed a patent application for a strip with a conductive pad for increased thrust

EM Drive engine. An article published last month in AIP Advances said that Em Drive emits the same waste as any other rocket gas. Arto Annila, Ph.D., a professor of physics and dissertation at the University of Helsinki, points out that "Em Drive works just like any other engine class like. " He says Em Drive's fuel is the same photon in length as the microwave. Photons in the machine will interfere with each other, so from the overall effect, good Like it's empty. "In an enclosed room, the incoming photons will rebound back and forth, and some of them will inevitably undergo complete destructive interference. At this time, two photons of electromagnetic The field will just offset, but the photon itself will continue to spread. "
