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? |

Those are good points, but it may be worth keeping in mind that the relevant distance from Neptune for a Nereid pass won't be Nereid's periapsis. It'll be more likely Nereid's distance from Neptune at the two points when Nereid crosses Triton's orbital plane. This will make it more than 1.4 million kilometres (though probably not by an enormous amount).
Of course, a Neptune orbiter would not be completely constrained to Triton's orbital plane, but it would tend to make things easier. Iapetus has only a 15-degree inclination to Titan's orbital plane, and this is still cited as being a substantial problem in setting up Iapetus flybys. I don't know what the angle is between the orbital planes of Triton and Nereid, but it wouldn't surprise me if it was larger than 15 degrees. |
