If you're happy and you know it, It's your med's! I'm concerned about the state of the wheels with the accelerating damage and the newfound concern for safer, less punishing routes. One of the reasons Curiosity is braving the dune at Dingo Gap is to reach the smoother terrain beyond. There is what looks like a crack in one wheel.
Will that crack spread? Will that wheel last 10 years? But I don't understand how this level of wheel damage is possible. The mass of the rover was known, thus its weight on Mars was known.
From the weight, the pressure a wheel would exert on a rock was known. The Mohs hardness of Mars minerals such as basalt is known.
Thus, one could calculate if a sharp rock would puncture a wheel.
