vjkane, I'm not suggesting its an ideal outcome, just one that might fall into the class of the good being the enemy of the perfect.
We might not get flagship class ice giant missions in any of our lifetimes. I expect some advance in ice giant science when the next generation of really big ground based telescopes come online,
but apart from that I was wondering what might be done with a New Horizons type package, with a magnetometer, with or without a probe.
Are there flight spares that could be used? Might this fit into a New Frontiers budget? And might there be opportunities for post ice giant flybys of TNOs?
