Earth’s proud tradition of drawing dicks on things has finally gone interstellar. Some intrepid Redditors spotted the above image on a NASA robotics site, and when the site went down–presumably due to increased traffic–NASA made the planetary penis more accessible, putting it on its own page.
It appears that the cosmic cock is the work of either Opportunity or Spirit, NASA’s two pre-Curiosity Mars exploration rovers. According to the Daily Mail, Earthbound engineers control the rovers’ movements, and often have to perform the kind of tight turns that would have created the dick drawing in order to test systems.
Let’s hope the spacey schlong stays on Mars forever. I can think of no greater testament to man’s ingenuity.
