Chasma Boreale Near Mars' North Pole
NASA's Mars Reconnaissance Orbiter reveals fine-scale details of the layers along a deep canyon's walls in Mars' north polar ice sheet. The canyon is a mile deep cleft into the ice sheet. Scientists do not know what caused its formation.
Chasma Boreale is the grand canyon of the north polar ice sheet of Mars. It is a mile deep cleft into the ice sheet, and scientists do not know what caused its formation. Using MRO, we can see fine scale stratified layers of the ice sheet along the canyon walls. These layers act almost as the rings of a tree do in recording the history of the structure. This animation zooms into the image taken by the High Resolution Imaging Science Experiment (HiRISE) on-board MRO.
