| Apr 6, 2017 at 14:57 | comment | added | HopDavid | @LocalFluff Your comment led me to look at a Jupiter gravity assist. Your RTG links (both on your comment below my answer and Hobbes' answer) lead to directories. Would it be possible to link directly to the pages you have in mind? | |
| Apr 6, 2017 at 14:54 | comment | added | HopDavid | @Tom11 I believe orbiters around gas giants are doable now. But NASA lacks funding to do every worthwhile project. Lack of sunlight is just one of the things that make such a mission more difficult and expensive. The long trip times are a major obstacle, in my opinion. Not only do these increase mission cost, it also makes it less likely those who planned the mission will live to see the fruits of their efforts. | |

The Hohmann calculation of course has to be greatly reduced, not only by aerobraking, but also by the Jupiter (and maybe Venus) gravity assist and the Solar electric propulsion that a Uranus mission actually would use. | |
