“The Committee has significant concerns about the technical challenges facing MSR and potential further impacts on confirmed missions, even before MSR has completed preliminary design review,” stated the Commerce, Justice, Science, and Related Agencies subcommittee in its report on the budget.
At the heart of the OC’s question there’s a valid and useful impulse. We should, as a society, always be asking whether we’re putting our resources in the right places. I just think that the case for space exploration dovetails pretty nicely into where OC wants to focus. Folks that want to shift funding into environmental reclamation are the natural allies of us space exploration nerds. It’s all science, it’s all toward improving humanity. Just need to get us all on the same side of the ball. :)
