L’article ne précise pas la nature chimique de la neige. Je serais très curieux de savoir si c’est de la neige d’eau ? De la neige carbonique ?

Edit :

Bon j’avais lu trop vite, avec une seconde lecture j’ai l’info ^^

Korolev crater is 82 kilometres across and found in 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). It is an especially well-preserved example of a martian crater and is filled not by snow but ice, with its centre hosting a mound of water ice some 1.8 kilometres thick all year round.
