Since the Neptune Orbiter thread has started to veer into talking about a Uranus orbiter as well, it seemed like a good idea to start a topic for Uranus.

Sounds great! You paying?

Seriously - that'd be an ideal way to do it - but if they can't find money to do one of them, they're not going to be able to find the money to do both.

Yes, I think just about any Outer SS science is looking marginal these days. Only the heavy-hitters (Europa, Titan, Enceladus, Jupiter and Saturn themselves) have a good shot at attention.

I will always be somewhat heartbroken that NH2 didn't come to pass, because the uranian flyby would have done an awful lot to address post-Voyager science there. With the extreme inclination and long seasons, the uranian satellites lose a lot of value as a potential target for the next *wince* 84 years. Given how long it was between Mariner 10 and Messenger, that sadly doesn't seem like such a long time.

I think the opportunistic use of a flyby en route to some deep-space (heliosphere) mission is the best bet that Uranus has, if we get a mission where the direction doesn't matter so much as the distance and we may as well point the ship at Uranus just to take advantage (and get a little gravity assist). But even such a mission would only carry nice camera in order to take imagery at Uranus, so it's not a total freebie.

Neptune/Triton carry a bit more clout, and lack the extreme seasonal constraints of Uranus, and I guess they'll get their closeup in, oh, about 30-40 years or so.
