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? |

Where are you going to get the power from...AND....where do you put the instruments - not seen a single mention of those yet in terms of mass, volume or power. I've not seen anyone, realistically, add up the figures here yet - just immediately jumping to "well - if the tank can be only 10cm then the whole thing will be 50 pence and return amazing science". You're jumping about 25 steps too far forward. You're talking about MRO's X-Band. That's 100 Watts. Where are you going to get 100 Watts from at Neptunian distances? That's just about 1/2 of NH's power budget gone right there. The mass of that power supply alone is going to be an order of magnitude above what you're talking about. So your delta V is going to be an order of magnitude less.
If you're going to do the outer solar system, as small, light and cheap as possible - the only logical place to start is New Horizons, the most advances, lightest, cheapest outer planetery spacecraft to date, and work from there. Doug |
