Researchers at the Massachusetts Institute of Technology (MIT) have introduced a groundbreaking dual-mode propulsion system for CubeSats, merging electrospray thrusters with a new green propellant known as the Advanced Spacecraft Energetic Non-Toxic propellant (ASCENT). Traditional chemical rockets provide powerful thrust but consume fuel rapidly, while electric propulsion systems are efficient but lack power. ASCENT, developed by the US Air Force, offers a safer alternative to hydrazine, requiring fewer handling precautions and providing a 50% increase in specific impulse. This new hybrid system allows CubeSats to utilize electrospray thrusters for efficient long-distance travel and switch to chemical propulsion for quick trajectory adjustments. The technology was tested successfully in a vacuum chamber, demonstrating the potential for sustained thrust. The upcoming Green Propulsion Dual Mode mission, scheduled for November, will further test this innovative propulsion system using a 6U CubeSat equipped with both thruster types. If successful, this could pave the way for advanced CubeSat missions, enabling exploration of Mars, Titan, and beyond.
