The AEPS is a solar electric propulsion system that uses xenon as its propellant, much like existing ion engines. Where it differs is in the power output, which should allow it to work as the ...

Let’s take a look at how ion thrusters work, and some of their interesting applications in the world of spacecraft! Chemical rocket engines provide huge thrust but are thirsty when it comes to fuel.

Ion thrusters are the most common primary engine powering satellites through orbital maneuvers today. But to travel from ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen ...

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 ...

Scientists have figured out how to create a new ion engine that uses 100 million times less fuel than a chemical rocket. Though the device is a lot less powerful, it could some day be a cost ...

we didn't know whether the coating damage was from accelerated ions directly hitting the engine or whether the coating damage was artificially mitigated by the deposition of carbon from ion ...
