Been there, done that

Been there, done that
Been there, done that Opportunity used her Pancam to take the self portraits above, in January 2014 (left), when her solar arrays was coated in the powdery Martian dust, and in late March 2014 (right) after the winds of Mars whisked off much of the dust from the arrays. As the Martian winds giveth, they also take away. A curse and a blessing the winds of Mars have enabled to live long and prosper. NASA / JPL-Caltech / Cornell / ASU
