It's been a while since I posted about what is happening at Gravitec Inc. and SFE. So last year, we had a major breakthrough in the engineering model of SFE, making it possible to generate thrust consistently in any direction. Being able to generate thrust in any direction every time, no matter the conditions, is critical to any propulsion system. SFE experiments periodically would suffer from the thrust vector drifting or changing direction. This phenomenon had been one of the major issues that needed to be solved to make SFE thrusters commercially viable. Last year, we discovered the root cause of this problem, and now we can generate thrust in the desired direction at the flip of a switch. What we have discovered has major implications for the understanding of the phenomenon and how it must be packaged for propulsion applications. This understanding has now become part of our many trade secrets in this subject matter.

The discovery is critical to the success of our planned CubeSat mission to test SFE in Space. The work continues towards performing an in-orbit test of an SFE thruster. The mission has one main objective: to raise and lower the orbit height of the CubeSat. This will prove that SFE is a viable space propulsion technology, but also provide us with hard performance data that will be critical to the development of future SFE propulsion systems.
Now that we can control SFE thrust on command, the research is focusing on increasing thrust beyond 1 Newton while keeping efficiency several times higher than any other form of conventional space propulsion.

Technology like SFE is critical for crewed and uncrewed exploration of the solar system. With technology like SFE, sending missions to the Moon, Mars, and other parts of our solar system would become routine and practical for both exploration and commercial applications. SFE would make asteroid mining not only possible, but also practical and profitable.

Good news, Hector. Getting above 1N thrust will be useful for the larger satellites, but also should be able to generate energy if you have a couple of them (for balance) spinning a generator here on Earth. Though mN levels are OK for satellites where you can wait longer, bit of a problem with air drag for showing an energy gain at ground level. Any idea yet of when you'll test this out in a satellite?
