The Rock that Appeared Out of Nowhere on Mars

Mars is turning out to be a mystery after all. Although to my eyes it appears it pushed up from below. The circle in the first picture may be a clue to that.

During last night’s celebration at the Jet Propulsion Laboratory of ten years of the Mars Exploration Rovers, mission principal investigator Steve Squyres shared several stories about the exploration and discoveries made by the rovers Spirit and Opportunity since they landed on Mars in 2004. An intriguing recent mystery is a strange rock that suddenly appeared in photos from the Opportunity rover in a spot where photos taken just 12 sols earlier showed no rock.

“One of the things I like to say is that Mars keeps throwing new things at us,” Squyres deadpanned.
