ice and frost on Mars
The image of Korolev crater was taken by the European Space Agency's (ESA) Mars Express orbiter, which launched back in 2003 and continues to operate today. ESA published the image in a press release in December, 2018, stating that it was captured using the orbiter's High Resolution Stereo Camera (HRSC).
Of the crater, ESA wrote in its 2018 press release: "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."
Scientists have known for several years that water ice exists on the Red Planet, with NASA stating in a 2019 article on its website that most of this ice is "locked away underground throughout the planet's mid-latitudes," and that astronauts could even use it as a resource.
Some water ice has also been observed on the surface before. ESA released an image of an unnamed Mars crater in the Vastitas Borealis plain back in 2005, seen here, that clearly shows "residual water ice" in the center.

“Usually we see partial rings, where a shape of half a circle surrounds an object, but in certain angles on relatively rare occasions, we see it as a perfect circle. The ring was produced by a massive galaxy in an estimated distance of a 11 billion light years awaywith a mass of ~650 billion suns, surrounding a galaxy with an estimated distance of 9-10 billion light years away.”
