Someone – perhaps a bored NASA engineer – has drawn a giant penis on the surface of the red planet.
The photo, sent back by NASA's Spirit rover, was spotted on NASA's website by a Reddit user earlier this week.
Spirit and Opportunity landed on Mars nine years ago. Spirit ceased functioning in 2010, whilst Opportunity continues to roll around, sending back data several years after its initial mission ended.
It has been suggested the phallic sketch was a natural consequence of Spirit's six-wheeled design, and it was created when the rover turned a corner.
NASA's website presents the image as a small thumbnail, with the option to 'enlarge'.
