Constructed from images by Mars Express’ High Resolution Stereo Camera (HRSC), a “flight” over the huge ice-filled crater Korolev on Mars.
>Korolev Crater is 82 kilometers (50 miles) across and at least 2 km (1.25 miles) deep. This well-preserved crater is located the northern lowlands of Mars, just south of a large patch of dune-filled terrain that encircles part of the planet’s northern polar cap (known as Olympia Undae).
That’s not snow you’re seeing, but this crater is constantly filled with water ice, and its central mound is about 1.8 kilometers (1.1 miles) thick all year round. It’s one of the largest reservoirs of non-polar ice on Mars.
