WTG NASA!!
In Europe we have to learn that you can't spend 10 times less in a martian rover and expect it to have a large enough failure margin for such a demanding mission.
If we want to do something BIG, inter-agencies cooperation is vital.
Imagine the robotics/telecommand expertise of NASA combined with Energy management and Life support experience from RSA, and instruments from Europe, Japan, Canada...
The ISS is good proof of it (damn good piece of engineering), so I hope we can work together to go even further.
