Evidence about its habitability.. New signs reveal the “secrets of Mars”
NASA's Curiosity probe has discovered evidence of the existence of lakes on Mars in the past, while a recent study revealed mounting evidence about the habitability of the planet billions of years ago.
The probe detected clay minerals on Mount Sharp, which is about 5 kilometers high, which were formed due to lakes and streams that were flowing through the central Gale Crater summit of Mars, according to NASA.
But those streams dried up into sand dunes and sediments, and the area turned from “rich in mud” to one “full of salty mineral sulfates,” indicating a major shift in the Martian climate that occurred billions of years ago, according to NASA.
A major shift in the climate of Mars occurred billions of years ago
In a related context, new research published by the "Science Alert" website points to several signs that some areas of Mars were suitable for life billions of years ago.
Through a comprehensive study of the images taken by the Mars Reconnaissance Orbiter, scientists discovered the presence of mud deposits in regions on the Red Planet.
The mud indicates the presence of water in the long term, and the research team believes that "water flowed on the Red Planet about 3.8 billion years ago to about 2.5 billion years ago."
Conditions for life were frequently available on Mars
"The mud deposits are located at a depth of 200 kilometers," which may indicate the presence of a lake under the surface of the Red Planet, says Catherine Weitz, a scientist at the Planetary Science Institute in Arizona.
Researchers believe that conditions for life were frequently available on the planet, until relatively late in the history of Mars, according to "Science Direct".
