NASA Pulling Out of ESA-led ExoMars Mission?
astroengine writes "It's a strange irony that to afford the expense of space exploration, international collaboration is often sought after — spreading the cost across several international partners means the biggest space missions may be accomplished. And yet in times of austerity, national budgets balk at the prospect of investing in international projects like ExoMars. Sadly, that's exactly what could be facing the ambitious ESA-led Mars rover/satellite mission if NASA's Science Mission Directorate budget is slashed in the next financial year. NASA may pull out of the project, leaving ExoMars with no rockets or a means to actually land on Mars. Could Russia help out? Possibly, but it will still lead to ESA taking on more cost than it has budgeted for."
I think it's disingenuous to say to ESA "hey, we can't cover this, hope you can find another partner" this far in. Maybe one can look at the overruns for MSL and JSWT and say that this is the responsible thing to do, to allow those two programs to finish, but in the middle and long term, this is going to prevent any further NASA-ESA collaboration. Where is the big dividend from having shut down the shuttle program?
