Excellent! There will be some amazing information coming from the various systems when they get to work on Mars.

Are there any "pre-emptive" criticisms of the instruments or the data they will be returning? That is, with the Viking experiments, the designers were confident that test results would be unambiguous, but of course after throrough analysis they were anything but. Has anyone done any work regarding possible holes that might become apparent when the data from the MERs is analyzed? This might help to avoid some of the ambiguity from early results. Of course it's too late to change instrument designs, but there is a fair bit of time to prepare for various possible interpretations of data.
