Mars Art: Something Old, Something New
I love this image. It is a view from the Mars Orbital Camera (MOC) showing layered rocks and dunes in the bottom of an unnamed crater in Arabia Terra, Mars. The rocks are extremely ancient sediments, laid down billions of years ago when the planet was young. One of the most impressive things to me is how nice and regular the layers are. The black dunes and the granule ripples that seem to radiate from the layered mesas are much younger. They are deposited and moved by the wind. Even still, on Mars everything happens slower and “young” is a relative term. Maybe these dunes are only millions of years old!
