Calculating the trajectory of rockets and building space stations is serious business, but every now and then, the good folks at NASA let their hair down and loosen up their neckties. Today, the agency published an image on their Flickr from their Messenger spacecraft of a crater on Mercury with the title: “Mickey Mouse Spotted on Mercury!” NASA explains:

“This scene is to the northwest of the recently named crater Magritte, in Mercury’s south. The image is not map projected; the larger crater actually sits to the north of the two smaller ones. The shadowing helps define the striking “Mickey Mouse” resemblance, created by the accumulation of craters over Mercury’s long geologic history.” (Photo: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington/Flickr)
