How Old is the Ice at Mars’ North Pole?

On Earth, the study of ice core samples is one of many methods scientists use to reconstruct the history of our past climate change. The same is true of Mars’ northern polar ice cap, which is made up of many layers of frozen water that have accumulated over eons. The study of these layers could provide scientists with a better understanding of how the Martian climate changed over time.

This remains a challenge since the only way we are able to study the Martian polar ice caps right now is from orbit. Luckily, a team of researchers from UC Boulder was able to use data obtained by the High-Resolution Imaging Science Experiment (HiRISE) aboard the Mars Reconnaissance Orbiter (MRO) to chart how the northern polar ice caps’ evolved over the past few million years.

Beautiful Image of Ice at Mars’ Northern Polar Cap

A new image from the ESA’s Mars Express spacecraft shows how beautiful, and desolate, Mars can appear. It also highlights some of the natural process that shape the planet’s surface. The image is of the northern polar region, and it features bright patches of ice, deep dark troughs, and evidence of storms and strong winds.
