NASA's Spirit rover landed on Mars on January 4, 2004 - and promptly sent this image of its welcoming party: a small humanoid.
Oh, and on its way to the Gusev Crater, the rover picked up an image of a Martian skull. NASA, of course, claimed that they were just rocks....
It even appears on the "raw" photograph they use to stitch together the panoramas (see: http://marsrovers.nasa.gov/gallery/all/2/p/1367/2P247720343EFFAWCCP2415L7M1.JPG ), so there's really no telling what the story behind it is. From the raw photo, though, I'm thinking it's a shadow, perhaps?
A really tiny, Martian Bigfoot. (also possibly a ninja and almost assuredly a zombie!)
:D
HA!
Keep curcluating the tapes!!!
