Wegener (Martian crater)

Wegener is an impact crater in the Argyre quadrangle of Mars, located at 64.6°S latitude and 4.0°W longitude.

It measures approximately 68.51 kilometres (42.57 mi) in diameter and was named after German geophysicist Alfred Wegener (1880–1930).

The name was approved by IAU's Working Group for Planetary System Nomenclature in 1973.

[4][5] With the stronger sunshine of spring in certain regions, carbon dioxide gas jets shoot dark dust in the air.

This dark dust will increase the absorption of light and cause the temperature to rise to where water can exist for short periods.
