Well I'm certainly no astrophysicist or even the armchair version. But it seems to me that wind levels on Mars can be quite energetic (relatively speaking).
At least enough to throw up some dust and act as dust devils.

These have also been postulated to be on of the reason why the solar panels seemed to get cleaned from time to time for no apparent reason.

5 Years on an other planet, think about it.
Imagine the amount of food, water, O2 and energy that would have been required if they had sent humans instead of machines.

Never mind the fact that they extended the original mission by more than 2000% and the fact that they never needed resupply missions.

When you read the mission reports for the ISS and see that they need a two man crew just to keep stuff from breaking too badly, it's hard to imagine the size of the crew that would be needed for a 5 year mission to Mars.

Yet one of the two (ISS vs Mars rovers), has a budget at least one order of magnitude larger than the other and has yet to produce any real science (unless teeing off a gold plated golf ball from the ISS is ones idea of science)
