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.

The plume of ions jetting out from the spacecraft therefore acts to provide thrust. It takes a while to build up momentum, however, because, despite moving at high velocity, the ion plume is ...

Regardless, ion propulsion is real and we have it today on more than one spacecraft. However, MIT recently demonstrated an ion-powered airplane. How exciting! An airplane with no moving parts that ...

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 ...

You're going to need some extra cleaning days in the next few months. Good thing this Shark ION Rocket cordless vacuum is just $139 today — that's $100 off its regular price. SEE ALSO ...
