Korolev (Martian Crater)
Korolev crater is located on the Planum Boreum, the northern polar plain which surrounds the north polar ice cap, near the Olympia Undae dune field. The crater rim rises about 2 kilometres (1.2 mi) above the surrounding plains. The crater floor lies about 2 kilometres (1.2 mi) below the rim, and is covered by a 1.8 kilometres (1.1 mi) deep central mound of permanent water ice, up to 60 kilometres (37 mi) in diameter.
Ice formation
The ice is permanently stable because the crater acts as a natural cold trap. The thin Martian air above the crater ice is colder than air surrounding the crater; the colder local atmosphere is also heavier so it sinks to form a protective layer, insulating the ice, shielding it from melting and evaporation. Recent research indicates that the ice deposit formed in place within the crater and was not previously part of a once-larger polar ice sheet. The ice in the crater is part of the vast water resources at the poles of the planet.

In popular culture
In the TV show For All Mankind, Korolev crater is the location of methane deposits that main character Kelly Baldwin seeks to investigate for signs of life.
In the 1996 science fiction novel “Encounter with Tiber”, written by Buzz Aldrin and John Barnes, Korolev crater is used as a base by extraterrestrials from the Alpha Centauri system. Who visited approximately 9,000 years ago.
