The ancient Martian lake could be inhabited

Curiosity has been investigating the mysterious Gale crater for years now, in which, judging by everything, billions of years ago there was a lake suitable for living organic life.

Over the past five years, the Curiosity rover has explored the Gale impact crater along and across, trying to detect signs of life. It turned out that this crater was not always a pit full of sand and dust. For 700 million years, between 3.8 to 3.1 billion years ago, it contained an ancient lake. Curiosity used Mount Sharpe, located in the center of the crater, to study sedimentary layers and thus learn the history of the Martian lake.

Analysis of the rock allowed the scientists to assume that over time, the amount of oxygen changed in the water, and with it the climate also changed. At present, researchers believe that for millions of years the lake has been suitable for living an organic life, as we know it on Earth. Even if we do not find traces on Mars, this information still plays a huge role for those who want to read the history of the Red Planet.
