|Bedrock Exhumed from the Deep|
Martian craters provide what tectonic mountain building and man’s TNT cannot: crater-exposed bedrock outcrops.
|The Beauty of Layered Stratigraphy|
The layered bedrock in this image was brought from several kilometers of depth during the formation of a crater in the volcanic plains of Lunae Planum.
|The Changing Dunes of Wirtz Crater|
On Mars, most sand is composed of dark basalt, a volcanic rock, so dunes here are darker than the ones on Earth.
|Crater with Exposed Layers |
Understanding the geology around impact craters can help scientists on Earth better understand what the walls of impact craters on Mars expose.
