What is Electric Propulsion? – Space Propulsion Laboratory

The #3Dprinted prototype was able to generate thrust more #efficiently than larger, more expensive #chemical rockets and outperformed existing droplet #electrospray engines. It can be produced rapidly and for a fraction of the #cost 💵 of traditional thrusters and even be fully made in #orbit 🌌 https://news.mit.edu/2025/mit-engineers-develop-fully-3d-printed-electrospray-engine-0212

MIT engineers develop a fully 3D-printed electrospray engine

MIT researchers demonstrated the first fully 3D-printed, droplet-emitting electrospray engine. The low-cost device can be fabricated more quickly than traditional thrusters, potentially from on board a spacecraft, and could enable CubeSats to perform precise, in-orbit maneuvers, aiding space research projects.

ESA’s Tiny Pinhole Thruster is Ready for Production. 

Rocket propulsion technology has progressed leaps and bounds since the first weaponised rockets of the Chinese and Mongolian empires. They were nothing more than rocket powered arrows and spears but they set the foundations for our exploration of space. Liquid propellant, ion engines and solar sails have all hit the headlines as we strive for … Continue reading "ESA’s Tiny Pinhole Thruster is Ready for Production. "
