This just out. Not earth-shattering, but colorful - maybe handy as an up-to-date

The strategy I envision is sort of a "one-note pony" theme; maybe two or three instruments per mission designed to answer a specific research question, that's it. Core assumption is that the launch vehicle is the vast majority of cost (and, yeah, the demise of the Delta II is a huge blow... ...hopefully new LVs from the independent launch enterprises like SpaceX will prove both more capable and less costly over time.)
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Core assumption is that the launch vehicle is the vast majority of cost (and, yeah, the demise of the Delta II is a huge blow... ...hopefully new LVs from the independent launch enterprises like SpaceX will prove both more capable and less costly over time.) I've been looking into readily accessible information on mission costs. A Discovery mission to Jupiter -- beyond perhaps a single, simple flyby -- seems impossible. The Juno mission is close to $1B with a limited (although not cheap) instrument set, a spinning spacecraft, solar power, and limited radiation hardening. I can't think of any mission that could come in at half the budget that could do useful science at Jupiter. The only idea that seems possible is a single Io flyby, and I have my doubts about that. -------------------- |
