This seems like a good place to start off the Uranus and Neptune forum: with the next ice-giants mission.
I will admit to not knowing a whole lot about the Neptune Orbiter With Probes (NOWP), other than the fact that it's in the planning stages, and a few other details I've gathered from Wikipedia and various other Internet sources. Anyone care to get this one going with a bit more information? |

I agree with practically all you say. As for using Triton I couldatoldya it won't work. It's too small and too high in Neptune's gravity well. Using gravity assists for orbit insertion requires a big body close to the primary to be worthwhile. Not even the Moon is much help when getting into an orbit around Earth.
Probably the best strategy would indeed be a conventional rocket for orbit insertion and a ion engine for the long haul out and for subsequent orbital adjustment. Perhaps the best solution might even be an NH-type orbit using a Jupiter gravity assist, and then running the ion engine the last few years before arrival to lose speed. |
