Fusion boffins apply plasma know-how to building thrusters

Are there any ISP Numbers

ISP = Specific impulse, not internet service provider.

It's a measure or rocket fuel economy.

For example the Dawn probe, which rendezvoused with Ceres and Vesta asteroids, had thrusters with a specific impulse of 3,100 s and produce a thrust of 90 mN.

Without ISP numbers, it's just a press release.
