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? |

Nereid: 27.6 deg with respect to Neptune's equator, orbital period 360 days, eccentricity 0.75(!)
Triton: 157.35 deg Not easy, but not impossible if it's done as a one-time-only good deal at system entry like Cassini's Phoebe encounter, I think; arrival timing would be everything. Getting out there again after entry into orbit even when Nereid is near periapsis (esp. if Triton is the prime focus, which is probable) seems unlikely in the extreme, esp. because the relative velocity would probably be pretty bad (Kepler strikes again!)...image smearing would be a significant concern, for example. Besides, Proteus is larger, probably more interesting, and far more accessible; I'd expect Nereid to be a lot like Phoebe. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
