Recent insights from ESA’s Mars Express reveal interesting specimens of snow on Mars ’Utopia – home to the largest planet ever seen not only on the Red Planet, but in the Solar System.

Utopia Planitia in context

Utopia is one of the three largest islands in the northern hemisphere of Mars (along with Acidalia and Arcadia) and is 3300 km in diameter: it is only twice as large as the north-south Sahara desert of the Earth.

This image shows a part of Utopia Planitia, the plain that fills this large and ancient cup.

It is thought that the plateau was created because the Utopia plate was filled with a mixture of sediments, lava flows and solvents (volatile substances, such as nitrogen, carbon dioxide). , hydrogen and water), all carried on the Martian surface by water. wind or other activities.

Ice boards

Utopia Planitia is a land of interest and rich in snow; Snow was seen lying beneath and just below the skin, and at great depths (seen by looking at holes and new holes, and by looking for deep layers of water. Mars and radar).

On the left and right sides of this model are visible slippery layers of skin called ‘mantled deposits’. These are thick layers of snow and dust that cleaned the skin and were left as snow when the rotational axis of Mars was more tilted than it is today (e.g. the case about 10 million years ago).

Topography of Utopia Planitia

Moving back to the center, the two large volcanoes seen here are surrounded by two treasure mounds. The various types of layers can be seen in the deposits built into the volcanoes, and in the thicker sections of the craters.

Brain land

These volcanoes are even more interesting. The second largest hole in this image (just below the left of the center) shows a phenomenon called ‘brain terrain’, where objects are fused into a concentric shape such as hard spots and bumps found on the skin. the human brain.

The brain plate is interspersed with ice found near the border between the northern plains of Mars and its southern highlands, a ‘dichotomy’ located in the south / south-west (upper left) of this feature.

The second idea is Utopia Planitia

On the right side of the pit where the brain is attached is a black piece of paint, which was formed when the fertile soil was cut with snow at low levels. This created polygonal features and cracks captured in the black soil blown over Mars by the wind, leading to the dark surface seen here.

Also, scalloped bumps can be seen in this photo. It is a ball in elliptical shapes, ten meters deep, and varies in size from ten to thousands of meters.

These symptoms are the result of melting or turning on the ice, which can cause the skin to weaken and fall off. On closer inspection, layers of cloak can be seen in and around these scalloped holes.

Different skin types

Mars Express has toured the Red Earth since 2003, capturing the surface of Mars, a map of its minerals, observing the composition and the orbit of its small space, Exploring under his neck, and exploring the nature of the various forms associated with the martian environment.

The High Resolution Stereo Camera (HRSC), responsible for these latest images, has featured extensively on various features of Mars, with new images showing everything from ridges to carved by the wind to geologically rich lands full of volcanoes, volcanoes, tectonic faults, rivers and ancient lakes. The camera also captured other views of Utopia Planitia, such as a portrait of Adamas Labyrinthus.
