Korolev crater
  لاوک ِ کورولیف   
lâvak-e Korolev

Fr.: cratère de Korolev   

An ice-filled → impact crater located in the northern lowlands of Mars at 73° north latitude and 165° east longitude, south of the large Olympia Undae dune field that partly surrounds Mars' north polar cap. Korolev crater is 82 km across with its centre hosting a mound of water ice some 1.8 kilometres thick all year round. The reason for the permanently stable water ice in the crater is because its deepest part 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.

The crater is named after chief rocket engineer and spacecraft designer Sergei Korolev (1907-1966), dubbed the father of Soviet space technology.
