The European Space Agency’s (ESA) Mars Express has captured some incredible images of the 82km wide Korolev impact crater on Mars, and this mosaic gives us a 3D view of what it would look like up close. Water ice can be found within Korolev crater because the deepest part of this depression acts as a natural cold trap, as air above the ice cools, making it heavier compared to the surrounding air, the mound is shielded from heating and sublimation.

This video was made using an image mosaic made from single orbit observations from the High Resolution Stereo Camera (HRSC) on Mars Express, combining data from the HRSC nadir and color channels. The nadir channel is essentially aligned perpendicular to the surface of Mars, as if you were looking straight down at the surface. Next, this image was then combined with topography information from the stereo channels of HRSC to generate a three-dimensional landscape.

The crater is named after chief rocket engineer and spacecraft designer Sergei Pavlovich Korolev (1907-1966), dubbed the father of Russian space technology. Korolev developed the first Russian intercontinental rocket R7, the precursor of the modern Soyuz rockets that are still operated today. With his rocket and spacecraft design, he was also responsible for the first human-made satellite (Sputnik in 1957) and for the first human spaceflight (Yuri Gagarin in 1961),” said the ESA.
