Scientists carefully analyzed the images taken by the Mars Reconnaissance Orbiter spacecraft. They are convinced that they show muddy structures, which could indicate the presence of liquid water on Mars.

Life could have existed on Mars for a long time

A study published in the journal Icarus reports that in the Ladon Valles region, clay structures can be found indicating the long-term presence of water from about 3.8 billion years ago to approximately 2.5 billion years ago.

Katherine Weitz, chief scientist at the Planetary Science Institute in Arizona, points out that the presence of clay indicates a favorable environment in which clays form and remain stable under neutral pH conditions where water is retained for long periods, minimizing evaporation of other minerals.

Weitz said the lake was most likely located in the Ladon Basin and North Ladon Valais. She added that the presence of mud and the location of the lake “had an impact on the environment that was favorable for life at that time.”

Scientists point out that the latest discovery does not prove the existence of life on Mars. Even if the planet had the necessary conditions to support life, this does not mean that living things existed. Even on Earth, there are places where there is no sign of life despite the presence of liquid water.

Our research shows that mud deposits deposited by running water in Eberswalde were not unusual, as we know many examples of similar young valleys depositing mud in the area, Weitz says.
