People love to find things on Mars. Sometimes it's a face, and sometimes it's a really happy face. Other times it's pyramids or even DNA.
This time, it's Bigfoot.
The Mars exploration rover, Spirit, took this picture in late 2007. Launched in June, 2003, Spirit is a solar-powered explorer that is walking along the surface of Mars to see what we can learn about its geological history. Its non-evil robot twin, Opportunity, set down on the other side of the planet to do the same thing.
But so far only Spirit has seen a Tusken Raider or Bigfoot or Xenu or whoever that is walking around.
Take a look for yourself.

Spirit was perched near the western edge of Home Plate when it used its panoramic camera (Pancam) to take the images used in this view. This view combines separate images taken through Pancam filters centered on wavelengths of 753 nanometers, 535 nanometers and 432 nanometers and is presented in a false-color stretch to bring out subtle color differences in the scene.

Or it could just be a rock.
But expect any number of people to cite it as proof of life on Mars.
