The Face on Mars Was a Trick of the Light
In 1976 a NASA orbiter photographed what looked like a giant face on Mars. Sharper cameras showed what it really is.

On 25 July 1976, NASA's Viking 1 orbiter photographed the Cydonia region of Mars from 1,873 kilometres up. One hill, lit by a low afternoon sun, looked like a human face staring up from the surface.
NASA's own caption described it as a rock formation whose shadows give the illusion of eyes, nose and mouth. Even so, the picture became famous, and some claimed it was a monument built by Martians.
NASA's Mars Global Surveyor photographed the area again: in April 1998 at 4.3 metres per pixel, and on 8 April 2001, in clear air, at 1.56 metres per pixel. Viking's view had been about 43 metres per pixel.
In the sharper pictures, the face disappears. What remains is an eroded, flat-topped hill, one of many in the region.
Exhibit A: the same hill, seen sharply

Evidence
- NASA's 1976 caption already explained the face as shadows on an eroded mesa.
- Mars Global Surveyor's 2001 image is more than 25 times sharper than Viking's and shows no artificial features.

Verdict
CONFIRMEDBacked by strong, verifiable evidence.
Confirmed natural landform. The face came from a low-resolution photo and low sunlight, plus the human habit of seeing faces in shapes.
