Jeans (Martian crater)
Jeans is an impact crater in the Mare Australe quadrangle of Mars, located at 69.8°S latitude and 205.9°W longitude. It is 80.2 km in diameter and was named after James Hopwood Jeans, and the name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN).[1] The pictures below show dark areas in which frost is disappearing and the dark ground beneath is being exposed.[2] Layers are also visible—probably from the many cycles of mantle deposition.
