What are the major claw symbols on the surface of Mars? View picture – 05/10/2022

Recent images of Mars show massive “claw marks” across the Earth’s red surface. But it is not the work of every alien dinosaur: it is just a fault line, created by a tectonic movement.

The grooves are part of the so-called land Tantalus Phossae. They are very large: they reach 350 meters deep and 10 kilometers wide, and can reach up to 1,000 kilometers.

The images were captured by spacecraft from the European Space Agency (ESA) Mars Express spacecraft – one of several rovers exploring Mars, either on the ground or in orbit. The stereographic data from the High Resolution Stereo Camera (HRSC) was processed using digital formats from around the world.

According to ESA, the images are projected in true color, as seen by the human eye, and in fact, “with a ground resolution of approximately 18 meters / pixel; the north is on the right ”.

What do we see?

LUB Tantalus Phossae is a tributary that runs to the east of a large, relatively flat, extensive volcanic formation called Alba Mons (also known as Alba Patera).

With about 1600 km in diameter and only 6.8 km at its highest point, it is the largest volcano in the Solar System, in area and volume.

“These trenches were created when Alba Mons emerged from the Earth’s rocks, causing the area around it to warp and erupt. The Tantalus Fossae faults are a good example of a surface feature called ‘grabens’, “explains the organization.

“Every trench was built when two equal offenses opened, causing the rock of them to fall into nothing.”

There is a similar fault west of the volcano Alba Fossae.

Why photos are important

New images can help better understand the world of creation and the timing of events. Admittedly, these models were not created all the time, but one after another – thus, some crossing or crossing over the impact craters.

The Mars Express mission has been orbiting the Earth since 2003, exploring its crust, weather, minerals, and various phenomena affecting the Martian environment.

The HRSC device has already expanded to cover many areas of Mars, including ridges, wind-sculpted landforms, tectonic faults, water channels and ancient lava lakes.
