While I marveled at the engineering invested in Spirit & Opportunity, one thing I thought conspicuously absent was a means of cleaning dust off the solar panels, particularly since they fully expected that to be an operational hazard, possibly even eventually fatal to their survival. In my mind, a compressed air tank - maybe even an onboard compressor to replenish it, wouldn't have been that difficult to include. I've often wondered about that lacking.
Meanwhile, I've been a bit surprised the next generation rover (officially, "Mars Science Laboratory" or 'MSL') hasn't been mentioned here - at least, anywhere i've seen. It's now been nicknamed - 'Curiosity' - and upon seeing its image for the first time I was greatly relieved to see it doesn't in the slightest resemble a cat.
The 'anti-stuck' strategy is apparently to go bigger - roughly twice the size of Spirit & Opp'ys wheels:
Curiosity will land on its own wheels (a first) - and
"has been outfitted with a new cutting-edge mobility system that's enough to make off-road enthusiasts drool with envy. The rover, which will carry ten times the payload mass of Spirit and Opportunity, is about the size of an SUV, and too heavy for an airbag landing.
It has a set of six wheels that are 20 inches in diameter -- larger than a car tire. Each wheel has its own motor, giving the rover independent six-wheel drive, and "cleats" that provide grip and help keep the rover from slipping when climbing over rocks or sand hills. The rover can also do swerving maneuvers and turn in place a full 360 degrees."
Scheduled for launch late November of this year, latest info I have says they still haven't decided on a landing site....a while back I saw something about a contest going on for suggestions, & same latest says they have narrowed it down to 4 candidate sites. For those curious, here's an overview of how it'll be equipped, etc.:
