It has always remained the prime focus of scientists, space explorers and astronomers to find other planets like our Earth that can support life. Mars is considered the most appropriate planet that can support life, for a very long time. Its atmospheric conditions prove to be favorable enough to support life on Mars.
Discoveries at Gale Crater
It is deemed possible that the ancient lake on Mars, the huge gale Crater, can support life. As in the depths, it contains environment which can help facilitate life like the ocean depths on Earth do. NASA’s Curiosity Rover has provided images that prove that this crater has multiple habitable environments that contain all the essential elements that aid life. This finding can prove vital for the researchers seeking traces of life on Mars for ages.
Microbial Life on Mars
Curiosity rover touched down the surface of this crater in 2012, in order to gather evidence whether this planet actually supported life or not. The aim was to target microbial life for no life seems to exist in a form greater than the microbes on Mars for long. The investigations of the Rover suggest that life could have existed some three billion years ago at this very crater. They say that the lake could have been once filled with water, but has dried out several times.
Water and different kinds of Life on Mars
Scientists have been working on the geological and chemical composition of the soil of the area and also trying to study the state of the minerals found in the rocks and soil of the crater. It appears that the rock deposits have been taking place in that lake for billions of years for such a rock formation on earth would take up to 10 million years according to geologists.
Geochemical researchers have found that there were far more oxidants near the surface than in the depths. This means that the surface water of the lake must have had plenty of oxygen, while, as you move deeper into the water, the oxygen level decreases to a notable extent. Through this discovery, we can presume that more than one kind of life forms existed on Mars back then and we can hope that some of that poor oxygen surviving kind must exist even today.
The above findings give an optimistic view over the concept of life on Mars. If the microbial life can survive, so can the larger organisms. The conditions on Mars appears more habitable than any other planet and the evidence of oxygen found shows that life must be there on Mars just waiting to be brought to surface by someone.
