Mystery of 'jelly doughnut' Martian rock solvedFebruary 14, 2014 @ 1:51 pm
PASADENA, Calif. (AP) - Scientists have solved the mystery of the "jelly doughnut" rock on Mars that appeared to come out of nowhere.
NASA said Friday that a wheel of the rover Opportunity broke it off a larger rock and then kicked it into the field of view.
The Internet was abuzz last month when the space agency released side-by-side images of the same patch of ground. Only one image showed the rock, which was white around the outside and dark red in the middle, and less than 2 inches wide.
Scientists had suspected that one of Opportunity's wheels kicked the rock as it drove. They received confirmation after analyzing recent images of the original piece of rock.
Opportunity recently celebrated 10 years on Mars. Its twin Spirit stopped communicating in 2010.
