- I was under the impression that there are space-qualified ion thrusters
- in the NASA inventory; these are very low-thrust, weigh about 10 kg, and
- are qualified for one year of operation. Of course, they do burn a
- pretty serious amount of power, but if you're willing to test a space-based
- nuclear reactor, you'll get all the power you need (25 kW in a small
- reactor). The only problem is decellerating upon reaching Pluto. The
- thrust from the ion engines is so small that you'd need to begin to
- slow down very shortly after passing the halfway point, which is
- not going to help make this a short mission.
