The so-called 'face' feature in the Cydonia region, photographed at high resolution by NASA's Mars Global Surveyor in 2001. Given the popularity of this landform, this high-resolution view was targeted by pointing the spacecraft off-nadir on 8 April 2001. On that date at 20:54 UT, the MGS was rolled 24.8° to the left so that it was looking at the 'face' 165 km to the side from a distance of about 450 km. The resulting image has a resolution of about 2 metres per pixel. If present on Mars, objects the size of typical passenger jet airplanes would be distinguishable in an image of this scale. The large 'face' picture, above, covers an area about 3.6 kilometres. Sunlight illuminates the images from the left/lower left.
