ESP_079719_1595  Science Theme: 
The Valles Marineris canyon system exposes some of the most diverse rocks on Mars. The plains surrounding the canyons also contain a variety of rock types, including at this location about 150 kilometers south of Eos Chasma.

Much of this image is dominated by an impact crater roughly 8 kilometers wide, which appears filled with sand ripples and also irregular mounds whose origin is unclear. The crater’s walls and the plains north of it exhibit a wide range of colors, some of which could be volcanic rocks whereas others likely record past interactions with water.
