Mars on Earth

How much they resemble each other: Chiemgau impact and Mars impact.

Below: This image was taken by NASA’s Mars Reconnaissance Orbiter on March 12, 2022. It shows a crater punched into the Martian surface, exposing several previously formed layers. Half of the crater was then destroyed when the Mars channel was opened. – NASA/JPL-Caltech/University of Arizona.

Interestingly, the Chiemgau and Mars craters are about the same size (50 m), with objects about 1.5 m in size still resolved in the Mars crater image.

With respect to the Tüttensee crater, it is remarkable in this Mars crater that also a terrace-shaped ejecta rim has developed after a part of the crater-facing wall has flowed back into the hollow form.
