An electrospray engine applies an electric field to a conductive liquid, generating a high-speed jet of tiny droplets that can propel a spacecraft. These miniature engines are ideal for small ...

MIT engineers have demonstrated the first fully 3D-printed, droplet-emitting electrospray engine. The device, which would be ideal for enabling small satellites to make in-orbit maneuvers ...

Electrospray (ES) thrusters generate low thrust via the electrostatic extraction of charged species from an electrified liquid. These systems are characterized by the propellant used and emission mode ...
