Mystery Rock 'Appears' In Front of Mars Rover 112
astroengine writes "After a decade of exploring the Martian surface, the scientists overseeing veteran rover Opportunity thought they'd seen it all. That was until a rock mysteriously 'appeared' a few feet in front of the six wheeled rover a few days ago. News of the errant rock was announced by NASA Mars Exploration Rover lead scientist Steve Squyres of Cornell University at a special NASA Jet Propulsion Laboratory '10 years of roving Mars' event at the California Institute of Technology (Caltech), Pasadena, Calif., on Thursday night. The rock, about 'the size of a jelly doughnut' according to Squyres, is thought to have either come from a freak "flipping" event or a very recent meteorite impact. However, the latter isn't thought to be very likely. Although they are still working on the rock's origin, the rover team believe it was 'tiddlywinked' by Opportunity's broken wheel; as the rover was turning on the spot, the rock was kicked from place under the wheel and flipped a few feet away from the rover. Never missing a science opportunity, Squyres told Discovery News, 'It obligingly turned upside down, so we're seeing a side that hasn't seen the Martian atmosphere in billions of years and there it is for us to investigate. It's just a stroke of luck.'"

Two remarks on the photo. One is that the specific 5 sided shape of the rock is disturbingly similar to the crack feature it is resting on as seen in the "before" picture. second, the rock is white.
I assume the latter is why they think it's a "flipped over" rock. But the two observations together are remarkable.
But remember this lander is huge, like the size of a mini van, and has metal tires, so the prospect of it being able to kick rocks would seem to be very large

I'm just dumbfounded at the implication here that the rover's ability to flip a small rock is regarded as luck. If it's such a valuable occurrence, should they not have included a rock-flipping function in the plans?
It would only make sense to include that sort of functionality if it would be regularly used, which isn't likely. Given the tremendous constraints that they are under for space and weight it probably doesn't make sense. As to what is lucky, there is more than one description for that.

Well, maybe it's not as trivial as it sounds to fit an appropriate robotic arm, the sensors to find a suitable rock, the software to try grabbing it and turning it over and compared to the weight, time and effort it's probably just not worth it. Assuming this is really the first time it's happened in the practically ten years (a week left) it's been on Mars it's somewhat of a freak accident, just the right size and shape stone was caught in the wheels in just the right way to flip it over. It's like a free bonus that you weren't even trying to get, isn't that lucky?
