May 9, 2017 – The collision that created Hargraves Crater impacted into diverse bedrock lithologies of ancient Mars. As a result, the impact ejecta is a rich mix of rock types with different colors and textures, as seen by NASA’s Mars Reconnaissance Orbiter (MRO).

The crater is named after Robert Hargraves who discovered and studied meteorite impacts on the Earth.
