Planet Mars: Flight over Korolev Crater | European Space Agency's Mars Express

This video, based on images taken by the European Space Agency’s Mars Express, showcases the 82 km wide Korolev crater on Mars. Located in the northern lowlands of the Red Planet, south of the large Olympia Undae dune field that partly surrounds Mars’ north polar cap, this well-preserved impact crater is filled with water ice all year round. The crater’s floor lies two kilometers below its rim, enclosing a 1.8 km thick domed deposit that represents a large reservoir of non-polar ice on Mars. 

Water ice is permanently stable within Korolev crater because the deepest part of this depression 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.

This video was created using an image mosaic made from single orbit observations from the High Resolution Stereo Camera (HRSC) on Mars Express. The mosaic combines data from the HRSC nadir and color channels; the nadir channel is aligned perpendicular to the surface of Mars, as if looking straight down at the surface. The mosaic image was then combined with topography information from the stereo channels of HRSC to generate a three-dimensional landscape, which was then recorded from different perspectives, as with a movie camera, to render the flight shown in the video.
