Thanks to ESA and their Mars mission “This movie, based on images taken by ESA’s Mars Express showcases the 82 km wide Korolev crater on Mars”

“Located in the northern lowlands of the Red Planet, south of the large Olympia Undae dune field that partly surrounds Mars’ north polar cap, this well-preserved impact crater is filled with water ice all year round. The crater’s floor lies two kilometers below its rim, enclosing a 1.8 km thick domed deposit that represents a large reservoir of non-polar ice on Mars. Water ice is permanently stable within Korolev crater because the deepest part of this depression acts as a natural cold trap. The air above the ice cools and is thus heavier compared to the surrounding air: since air is a poor conductor of heat, the water ice mound is effectively shielded from heating and sublimation.” Read more from the source: ESA Youtube Channel Here and ESA terms of use
