There are river deposits across the surface of Mars, which refers to the existence of a surface environment from over 3.5 billion years ago. Which once supported liquid water at the surface.

Aeolis Dorsa is a region of Mars which contains some of the most spectacular and densely packed river deposits.

Satellite images observes these deposits as they have undergone a process called “topographic inversion”.

B.T. Cardenas and colleagues from the Jackson School of Geosciences identify fluvial deposit using high-resolution images and topographic data from cameras on orbiting satellites. It stacks patterns and changes in sedimentation styles controlled by a migratory coastline.

On Earth, incised valleys are commonly cut and filled during falling and rising eustatic sea level. In fact, on Mars, the method that measure river paleo-transport direction is developed. These measurements demonstrate that the studied river deposits once filled incised valleys.

According to the conclusion of Cardenas and colleagues, similar falling and rising water levels in a large water body forced the formation of the paleo-valleys in studying the area.

water level on Mars

There are indications of multiple episodes of water level fall and rise, each well over 50 meters, a similar scale to eustatic sea level changes on Earth. This reveals about multiple episodes of water level fall and rise.

There is some long-term stability in the controlling, downstream water body, which would not be expected from catastrophic hydrologic events. That is a suggestion as large water level fluctuations and coastline movements were recorded by these river deposits.

The quest on Mars aims to follow the water as a search for life in the universe. A convincing science validates all these suspicions. This is a significant work as it asserts that water is flowing today on the surface of Mars.

Thus, these flows are known as recurring slope lineae (RSL ). They often have been described as possibly related to liquid water. There are hydrated salts on the slopes that point to what that relationship may be to these dark features.

The hydrated salts

As salt on roads here on Earth, The hydrated salts would lower the freezing point of a liquid brine. Salt on roads causes ice and snow. it’s enough water wicking to the surface to explain the darkening, Scientists say it’s likely a shallow subsurface flow.

Scientists say it’s likely a shallow subsurface flow. Anyway, the detection of hydrated salts on these slopes means that water plays a vital role in the formation of these streaks.
