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. -------------------- |

Kind of why I'm prodding this, also acknowledging that my odds of seeing another Flagship aren't great (about to turn 45 here); I want more!!! One of the reasons for the cost caps seems to be best stated as "deprivation drives innovation". I don't really agree with that idea, but if the paradigm can indeed be effectively utilized then hopefully the planetary science community can do so. EDIT: May have strayed too far into the policy & strategy region over the last few posts. Admins, please do what you feel is appropriate... -------------------- 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.
