Curiosity’s Dusty Selfie

Since August 2012, Curiosity has been exploring 3-mile-high Mt. Sharp in Gale Crater. The rover has climbed more than 2,000 feet (612 meters), reaching progressively younger rocks that serve as a record on how Mars has evolved from a wet, habitable planet to a cold desert environment. via NASA http://www.nasa.gov/image-feature/curiositys-dusty-selfie
