history
Eponym Sergey Pavlovich Korolev

The Korolev Crater is an impact crater in the Mare Boreum Gradfeld on Mars . It measures about 81 km in diameter and was named after Sergei Korolev , a Soviet rocket engineer , during the space race .

The 2 km high walls of the crater create a cold air lake inside . Air flowing over the ice is cooled and becomes denser. The high crater walls prevent them from escaping and thus create an insulating layer of air on the ground. This means that a layer of water ice up to 1.8 km thick can stay in the crater all year round . Altogether there are probably between 1400 and 3500 km³ of water ice in the crater.

The structure of the ice deposits is very similar to the layer deposits in the Planum Boreum ( North Polar Layered Deposits) about 600 km further north; both ice formations probably formed at the same time and by the same mechanism.
