A “Green” Dual-Mode Engine is About to Give CubeSats the Best of Both Worlds
Researchers at MIT have developed a dual-mode propulsion system for CubeSats that combines the efficiency of electric thrusters with the power of chemical propulsion, using a safer, more efficient "green" propellant called ASCENT. This innovation allows CubeSats to perform long-duration, low-thrust maneuvers and then switch to high-thrust adjustments when needed, expanding their mission capabilities. The technology is being tested in NASA’s upcoming GPDM mission, which will launch a 6U CubeSat equipped with both thruster types and a single fuel tank. The use of ASCENT reduces handling risks and improves performance compared to traditional hydrazine-based fuels.
Engineers have developed a new propulsion system for CubeSats that combines chemical and electric thrusters using a safer, more efficient green propellant.
This hybrid system could enable CubeSats to perform complex missions, like navigating to distant planets and adjusting course precisely, while reducing risks from toxic fuels.
The innovation supports safer, more versatile space exploration, offering practical benefits for future scientific and commercial satellite missions.
