Amazing insight into Mars. Never-before-seen images from the surface of the Red Planet

There is a canyon on Mars that makes Earth's famous Grand Canyon look small.
The European Space Agency (ESA) recently published stunning images of two great chasms in this gigantic canyon system, called Valles Marineris.
On the left is Ius Chasma, over 840 kilometers long, and on the right - Tithonium Chasma, with a length of 800 kilometers.
These great chasms, which reach a depth of about 7 kilometers, represent only a section of the Valles Marineris (for reference, the Grand Canyon is just over 1.5 km deep.) "Being the largest canyon system in the Solar System, it would span the distance from the northern tip of Norway to the southernmost point of Sicily," ESA said in a statement.
These great chasms were formed by the ancient activity of tectonic plates drifting apart, the ESA explains. Although Mars is not nearly as geologically active today, it is by no means dormant. Earthquakes of great proportions still shake the Martian soil, perhaps triggered by magma, or molten rock. NASA's InSight probe has recorded more than 1,300 earthquakes on Mars (as of early May 2022).
"Mars remains an active planet, just not as active as Earth," Mark Panning, a planetary scientist, and project manager for NASA's InSight probe told Mashable.
