Nasa says Mars mystery rock that ‘appeared’ from nowhere is ‘like nothing we’ve seen before’
“We had driven a metre or two away from here, and I think the idea that somehow we mysteriously flicked it with a wheel is the best explanation,” Squyres said.
Yet the story got even stranger when Opportunity investigated further. Squyres explained: “We are as we speak situated with the rover’s instruments deployed making measurements of this rock.
“We’ve taken pictures of both the doughnut and jelly parts, and the got the first data on the composition of the jelly yesterday.
“It’s like nothing we’ve ever seen before,” he said. “It’s very high in sulphur, it’s very high in magnesium, it’s got twice as much manganese as we’ve ever seen in anything on Mars.
