That’s why NASA developed the H71M sub-kilowatt Hall-effect thruster, a next-generation ion engine that can supply a velocity change. The propulsion system must operate using low power (sub ...

Unlike most interplanetary probes, Dawn is not propelled by a chemical rocket engine, but by a solar-electric ion propulsion system, particularly suitable for long-distance flights. This innovative ...

Ion engines won’t get you out of Earth’s gravity well, nor do they work in the atmosphere, but become useful when you’re in the vacuum of space. Credit: NASA, public domain Before we dive ...

Supercomputer simulations advance electric propulsion by tackling ion plume challenges for safer space missions.

A research team presents an AI assessor for Hall-effect ion thrusters, the engines of satellites and space probes.

NASA completed a full-duration, 500-second hot fire of an RS-25 certification engine Jan. 17, continuing a critical test series to support future SLS (Space Launch System) missions to the moon and ...

Recently NASA announced earlier this month that the ... system that uses xenon as its propellant, much like existing ion engines. Where it differs is in the power output, which should allow ...
