Valles Marineris on Mars, 20 times wider than the Grand Canyon, is visible in this stunning new photo

The vast Valles Marineris canyon has been revealed in stunning new images taken by the European Space Agency’s Mars Express.

The Red Planet’s canyon is 2,485 miles long, more than 124 miles wide, and more than 4 miles deep, making the US very dim by comparison. Wallis Marineris extends from the northern tip of Norway to the southern tip of Sicily.

The new image depicts the two moats, or chasma, that make up the western part of Valles Marineris. On the left is Lus Chasma which is 521 miles long and on the right is Tithonium Chasma which is 500 miles long.

The image uses data from the High-Resolution Stereo Camera (HRSC) aboard Mars Express and is a “true color” image, meaning it shows what the human eye would see when viewing this region of Mars.

The vast valley of the Red Planet has been revealed in new pictures released by the European Space Agency. The new image depicts the two moats, or chasma, that make up the western part of Valles Marineris. On the left is Lus Chasma which is 521 miles long and on the right is Chasma Tithonium which is 500 miles long.

The Red Planet Canyon is 2,485 miles long, more than 124 miles wide and more than 4 miles deep, making the Grand Canyon of America a comparatively poor sight.

This image of Tethonium Chasma shows parallel lines and rubble piles (top right) that depict recent landslides.

In terms of altitude, the highest mountain in the Alps, Mont Blanc – rising more than 15,000 feet above sea level – would be a dwarf if placed within Tithonium Chasma.

Unlike the Grand Canyon of the Americas, which formed about 5 million years ago when the Colorado River eroded, the Red Planet’s giant canyon is believed to have been formed by the erosion of tectonic plates.

At the top of Tithonium Chasma, a patch of darker sand – possibly from a nearby volcanic region – imparts contrast to the image.

Next to the dark mound are two light-colored hills, one of which is divided by an upper photo frame.

This image taken by Mars Express shows a perspective view of Mesa in the eastern region of Wallace Marineris, the largest valley in the Solar System.

Mars: The Basics

Mars is the fourth planet farthest from the Sun, with a cold, dusty desert world that is near death with a very thin atmosphere.

Mars is also a dynamic planet with seasons, polar ice caps, canyons and extinct volcanoes, evidence that Mars was more active in the past.

It is one of the most discovered planets in the Solar System, and the only one that has been discovered by humans.

A day on Mars is more than 24 hours long and there are 687 Earth days in a year.

Facts & Figures

Orbit: 687 days

surface area: 144.8 million square kilometers

distance from the sun: 227.9 million km

gravity: 3,721 m/s

RADIUS: 3389,5 km

Moon: Phobos, Deimoso

These hills are really huge, reaching more than 9,800 feet in height. For perspective, Mount Hesperus in Alaska, the highest peak in Revelation Mountain, rises 9,828 feet.

Strong Martian winds have badly eroded the mountainous surface: typical average wind speeds on the Red Planet are 125 mph, with gusts of 300–375 mph.

A series of small outcrops can be seen between the large hills.

According to the European Space Agency, Mars Express previously found water-containing sulfate minerals in the region.

The space agency says this suggests a bulge that formed when the liquid that once filled the gap evaporated – but this has been disputed by scientists.

ESA said in a statement.

This signal can also be seen in the topographic diagram below.

ESA explained that “the landslide was caused by the collapse of the canyon wall on the right, and it was probably relatively recent because it was not badly eroded.”

“The rogue realm of Ius Chasma is also extraordinary.

“When tectonic plates broke apart, it appears to have formed a jagged rock triangle that looks like a row of shark teeth.”

Over time, rock formations collapse and erode.

The European Space Agency’s Mars Express rover has been orbiting the Red Planet since 2003 to conduct a variety of scientific experiments, including imaging the surface of Mars, mapping its minerals, determining the composition and circulation of its atmosphere, and exploring beneath its crust. includes doing.

It was also NASA’s Mars Perseverance rover that explored the Red Planet for about a year and a half. The US space agency wants to send humans to Mars in the 2030s.

SpaceX founder Elon Musk has long said that humans must colonize Mars and become a multi-planetary species in order to maintain and expand consciousness in the universe.
