When it comes to space exploration, large vehicles get most of the press -- but a team on KickStarter wants to build an engine that could power nanoscale satellites on their own journeys of ...

A form of electric propulsion known as Hall thrusters — a type of ion thruster — may actually pack more bang for the buck than expected. Hall thrusters have conventionally been used to adjust the ...

It sounds like a NASA pipe dream: a new spacecraft thruster that’s up to 40 percent more power efficient than today’s. Even better, its fuel costs less than a thousandth as much and weighs an eighth ...

You don’t see many ionic thrusters out in the world these days. The high-voltage devices are interesting pieces of technology, but they aren’t all that relevant to our normal lives. They’re gradually ...

Today, we use ion thrusters to correct satellite orbits and visit asteroids. In 100 years, we might be using them to propel massive generation ships that send colonists to a different part of the ...
