Playfair is a lunar crater that is located in the rugged southern highlands on the near side of the Moon. It lies along the eastern rim of the eroded satellite crater Playfair G, a formation that is almost twice the diameter of Playfair itself. Playfair is nearly due north of the crater Apianus, and to the southwest of the Abenezra– Azophi crater pair.
This crater is oval in shape, being slightly wider along the east-west axis. The rim is somewhat eroded, and tiny craterlets lie along the south and west rims. The interior floor is level and nearly featureless, with the only feature of the minor interest being a pair of tiny craterlets lying just to the east of the midpoint.
Playfair Crater is an impact crater in the Mare Australe quadrangle of Mars, located at 78.1°S latitude and 126.2°W longitude. It is 64.2 km in diameter and was named after John Playfair, and the name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN).
This picture was taken in the spring season on Mars when the temperature was rising. During the winter, much frost accumulates. When the temperature goes up in the spring, the frost disappears in the thin Martian atmosphere and leaves behind the dark ground. The surface appears covered with dark spots when this defrosting process is occurring.
The dark spots can be seen in some of the pictures below.
