Electric propulsion is being increasingly used on space missions and could ultimately replace thrusters using chemical ...

You can see the video explaining that, below. To understand why, you need to know two things: how ion drive works and how the engines differ when using them in an atmosphere. Let’s start with a ...

For example, in Spock’s Brain, the alien-of-the-week’s ion drive gave Scotty engineering envy. However, in The Menagerie, the computer identifies a Starfleet shuttlecraft as having ion propulsion.

The fuel economy of the ion drive enables Dawn to follow an ambitious trajectory, which would not be possible with a chemical engine while still remaining within the cost limits. For the first time in ...
