I'm struggling to understand how colliding with a rock at a speed of a few centimetres per second could have been "mission catastrophic". (Just as well my car is more robust.)

One wonders whether Oppy's accelerometers are used in general drive usage for instance to adjust drive behavior over small rocks, which should nullify hazards such as this, since any sensed impasse should signal to adjust suspension, wheel spin, etc. in adaptation to the terrain feature encountered... or maybe they are only used to measure degree of tilt? i'm sure im oversimplifying it and someone here is probably familiar with those specs..

On a typical drive accels and gyros are used to monitor rover attitude and the suspension system is also monitored but in this case they would not have detected a collision with such a big rock. And before you ask, no I was not on shift that day ;-) Paolo -------------------- Disclaimer: all opinions, ideas and information included here are my own,and should not be intended to represent opinion or policy of my employer.
