“Every spring, the sun shines on one side of the Mars Arctic stack, which is called the Arctic layered sediment,” wrote planetary scientist Candy Hansen. “Warmness makes the ice become unstable and starts to loosen.”
The ice was "fish roll-over" at a height of 1640 feet (500 meters) and a huge cloud of dust in May. The dust cloud is fully shown in the image released this week.
The Mars Reconnaissance Orbiter has been orbiting the Red Planet since 2006, providing images of Mars's fascinating terrain. The spacecraft has even identified potential landing points for the SpaceX interstellar spacecraft.
