The Mars Jelly Doughnut Mystery Is Solved

On January 8th the Mars rover, Opportunity sent back an image of an unusual rock with a white edge and a red centre. The rock was termed ‘Pinnacle Island’ and also named the Jelly doughnut because of its uncanny resemblance to the sugary snack. The real mystery though was that the rock hadn’t been evident 4 days earlier so how did it get there? The answer, it turns out, is that the track of Opportunity ran over a rock and fractured it (see upper arrow). Once the rover was moved a second matching fragment was found uphill with the distinct markings of a tyre track running over it. Mystery solved and still no evidence of martians throwing stones at rovers.
