A high resolution camera aboard ESA’s Mars Express orbiter captured pictures of the Noachis Terra region on Mars, focusing on the Maunder Crater. This crater, located in the southern Martian highlands, is the result of an impact and was named after Edward W. Maunder. The crater is 90 km in diameter and about 900 meters deep, and is not among the larger impact craters present on Mars. In recent times, the western slope of the crater has begun to fail, triggering landslides and transporting material eastward. Portions of the collapsed western slope now contain gullies. In the eastern sector, there is a deep trough slicing across the crater floor, which may be the result of landslides on the western edge. There are also features called Barchan dunes, a geological feature also present on Earth in the West-African Namib desert.
