re: "Dust Devil Weather?" A speculation
Looking at some images of the ground around the rover - there's some evidence that actually the dust devil did go straight over the top. Normal local winds wouldnt do the big shovelling of dust that we see. There is orbital imagery evidence to suggest dust-devils form on the north/north easter slopes of craters or hills - and the move south east. Seing as we're on some hills, it's not unlikely that if devil-forming conditions were to occur - the rover would get 'hit'
