Yep, not perfect (I'd prefer the Uranus orbiter and the Nepture / KBO flyby) but I understand the rationale.
Something has got to happen soon, or just about everyone on this board will be pushing up daisies before we return to the outer solar system.

Thanks for the info, my friend. I hear you in that I do hope something does happen soon as I'm 51 and if it doesn't, I'll be pushing up daisies like you said. It would be a dream come true, a proper exploration of Uranus & Neptune.

51 also , and if things do not change soon then....

well there is still a lot of older imaging data to work through with new tools

Interesting, if speculative paper on the ArXiv today about possible electrodynamic tether spacecraft capture into orbit at Neptune.

https://arxiv.org/pdf/2003.07985.pdf

Given the similarities between both ice giants with respect to size, mass, offset dipole and field strength, I cant see why this wouldn't apply to Uranus too?

Here's the OPAG paper on the arXiv. The summary is interesting.

This is great news! Finally. Lets hope it happens.

Should be called 'Herschel', but of course that's been taken.

I hope the probe doesnt end up getting descoped.

Asinine jokes aside, this will prove to be an epic mission.

Proposals for Uranus orbiters have had flight times of about 12 years before arrival. We might optimistically expect this mission to begin in the early 2040s. Let's hope that we're all around to see this happen. Results from a Neptune orbiter are starting to look unlikely for anyone who's currently over the age of 40.

A Neptune flyby would be acceptable for me at least.


Is Neptune/Eris encounter possible with a New Horizons type mission?

I imagine the geometry that would allow that kind of trajectory would be very rare.

I wonder if any of the really big KBOs might be in the right position at some stage in the near future?

There are a lot of KBOs. It wouldn't be difficult at all to have a Neptune flyby continue on to make a targeted flyby of one of them, but there would be a tradeoff between the choice of the desired KBO and the choice of the trajectory through the Neptune system, which would surely make Triton a major priority, but would allow at least some flexibility by choosing where in its orbit Triton would be at encounter time.

But to visit at least one KBO wouldn't be a challenge. I know that the scale is deceptive, but this almost makes it seem like it'd be hard not to come close to one of them after the Neptune encounter.

I came across this movie of Uranus and its moons moving against the stars -

Attached Image


"The featured video captured by the Bayfordbury Observatory in Hertfordshire, UK is a four-hour time-lapse showing Uranus with its four largest moons in tow: Titania, Oberon, Umbriel and Ariel. Uranus' apparent motion past background stars is really dominated by Earth's own orbital motion around our Sun."
