Face on Mars
This perspective image was recorded during orbits 3253 and 1216 by the High Resolution Stereo Camera (HRSC) on board Mars Express and shows a remnant massif, viewed from the southwest. The massif is thought to have formed via landslides and an early form of debris apron formation. It is characterized by a western wall that has moved downslope as a coherent mass (on the near side of the massif in this view). The massif became famous as the Face on Mars in a photo taken on 25 July 1976 by the American Viking 1 Orbiter.
The image is based on data gathered over the Cydonia region, with a ground resolution of approximately 13.7 metres per pixel. Cydonia lies at approximately longitude 350.54° E and latitude 40.75° N.
