I'm interested in how this could possibly work. Nuclear powered engines still need some sort of propellant. Nuclear reactors on our boats use steam to turn the props, which gives it thrust... but in the void of space there isn't any water or enough gas for this method to work.

I think it would be interesting to see what they come up with.

Tests at NASA's Jet Propulsion Laboratory in Pasadena, California, showed that a jet of ionized atomic particles can furnish propulsion.

I guess it tells me right here. hehe
