NASA's Spirit rover may be getting a little cheeky over there on Mars.
In a photo of Spirit's track patterns, published on the robotics section of NASA's Jet Propulsion Laboratory site, the Mars rover appears to have traced out a very phallic design on the Red Planet's dusty surface.
The rover's picture went viral after being posted to Reddit's r/funny subreddit page Tuesday, earning close to 40,000 "upvotes" in a matter of a few hours. According to The Huffington Post UK, NASA's website crashed due to increased traffic as word of the "drawing" spread.
The rover landed on Mars in January 2004 and is equipped with a set of tools to study rocks and soils that may hold clues to past water activity on Mars.
Correction: A previous version of this article reported that the Mars rover Curiosity made the penis-shaped tracks on the red planet, but it was in fact the rover Spirit.
