North Pole - Viking Orbiter 1 - Orbit 768 - 07-29-78

Viking Orbiter 1 image of the Martian north pole, taken during routine monitoring of the north polar cap. This image was taken early in the Martian summer, when the polar cap had begun to shrink but not reached its minimum extent for the summer.

 

This image was taken on July 29, 1978 by Viking Orbiter 1, during its 768th revolution around Mars.
