It seems like NASA's rovers have something in common with Seth from the movie, Superbad: They like drawing pictures of penises. Unlike Seth, though, the rovers have taken their particular phallic sketch out of this world--all the way to Mars.

The twin Mars exploration vehicles, named Spirit and Opportunity, were launched nine years ago in an effort to survey the surface of Mars for signs of water erosion and, possibly, life. During their search, their tires left distinctive tracks on the Martian surface. The tracks, it turns out, created a dick picture that can rival the ones drawn by high school boys.

The problem, it turns out, lies in the rovers' actual programming. In order to find new routes, NASA scientists designed the rovers to spin in tight circles to test nearby terrain. This, in turn, helped create the massive penis that is now etched on the surface of the Red Planet.

The picture has been around for a while, but it's only recently that it was discovered by Reddit. The influx of users essentially crashed NASA's website. After all, who doesn't want to see a giant penis picture drawn on the surface of another planet?

It's unclear exactly which of the rovers drew the shape or even when it was made (though our money is on Opportunity), but it's possible that this phallic image has been around for years. NASA lost communication with Spirit in 2009 after it became stuck in some sand. Opportunity, in contrast, is still roaming over the surface of Mars on its way to the Endeavour crater. We can only hope that its dick-drawing tendencies don't surface again any time soon. After all, we don't need extraterrestrials thinking that we're that into phallic images.
