What is the newly discovered water ice reservoir on Mars?

According to PSI senior researcher Daniel Berman, radar examination has revealed a water ice layer in the Nereida Montes region that could be up to 500 meters thick and almost 100% ice with a covering of debris. This significant discovery potentially represents the largest collection of water in the southern hemisphere of Mars outside the polar regions. Using data from NASA's Mars Reconnaissance Orbiter, researchers identified these ice stores which date back to the last few million years of the planet's history. This finding connects with other research on the history and current presence of water on Mars, providing crucial information for understanding the planet's water cycle and supporting future exploration missions.
