NASA's Spirit Mars rover created these tracks shortly after touching down in 2004 to execute a turn, not amuse its handlers.
This photo from NASA's Mars rover Opportunity shows what at first glance appears to be a bunny rabbit head on the Red Planet. The image was released in March 2004 in the "mission success" panorama, and the bunny is an illusion likely created by a piece of Vectran cloth from Opportunity's lander.

A mysterious object spotted on the surface of Mars by David Martines while he was perusing the planet using Google Mars, a mapping program. What Martines described as a Martian "Bio Base" is actually an artifact caused by a cosmic ray interference, experts say.
NASA'S Mars Exploration Rover Spirit captured this westward view from atop a low plateau where Spirit spent the closing months of 2007.

A perspective view showing the so-called 'Face on Mars' located in the Cydonia region. The image shows a remnant massif thought to have formed via landslides and an early form of debris apron formation. The massif is characterized by a western wall that has moved downslope as a coherent mass. The image, created with data from the Mars Express orbiter, was released Sept. 21, 2006.

This image of Mars taken by NASA's Mars Reconnaissance Orbiter shows what some psychics have claimed to be evidence of life on Mars.
This new image of Mars taken by NASA's Mars Reconnaissance Orbiter shows an optical illusion. What appears to be trees rising from the Martian surface are actually dark streaks of collapsed material running down sand dunes due to carbon dioxide frost evaporation. The image was released in Jan. 2010.
