    We love flyover videos from other worlds. These stunning videos, created from imagery gathered by orbiting spacecraft, can give us a sense of what it would be like to fly in an airplane on another planet.

    This latest flyover video from the European Space Agency's Mars Express spacecraft, provides a stunning view of one of Mars' most eye-popping craters.

    That's not snow you're seeing, but this crater is constantly filled with water ice, and its central mound is about 1.8 kilometers (1.1 miles) thick all year round.

    "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.

    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).

    This movie was created using an image mosaic made from single orbit observations from the High Resolution Stereo Camera (HRSC) on Mars Express, which was first published in December 2018. The mosaic combines data from the HRSC nadir and colour 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".

    While The Oscars are a shallow award for entertaining industry, videos like this should be nominated

    Perhaps create a subsection where videos can compete against their peers

    Name for the name of the subsection anyone?

    I'll raise your Korolev crater with a Mars thigh bone

    Sadly thigh bone never made this list

    Looks like the sun never rises much above the horizon in this area of Mars. Note where the ice has melted form the crater sides, showing the "attitude" of the sun's position.
