Many of the instruments on the Mars Rovers are European designed and built....

I thought only the moessbauer spectrometer was EUropean. That was comercially contracted to, I thought. I did not think it was purchased by the ESA. There is no ESA scientific component to the Rover Missions, as I unerstand it.

There will be at least one on the next rover mission though maybe two.

There are not really verymany "instruments" on the rover missions, really.

What other instruments are Europeanon the Rovers?
