A study by American scientists found that Mars used to have a lot of carbon dioxide. This finding helps reinforce that life once existed on Mars.

Scientists say there is a wide distribution of carbonate minerals at a depth of about 6.4 km compared to the Martian surface.
Previously, scientists have found this mineral on the surface of Mars, however in small quantities. If this mineral reserve is abundant, it means that hundreds of millions of years ago on Mars there was a large amount of carbon dioxide.
The very existence of carbon dioxide has ensured that the Martian surface maintains a warm and humid state, thereby providing ideal conditions for human life.
Scientists analyzed the geological conditions of an area on Mars's surface by taking advantage of satellite data. The area studied by scientists is " Layton Crater ," located near the volcanic area of Syrtis Major - the largest volcano on Mars.
Through data analysis, scientists discovered a large amount of carbonate minerals widely distributed at a depth of about 6.4 km compared to the Martian surface.
According to scientists, the most likely carbonate minerals are derived from water containing large amounts of carbonate. So scientists believe that volcanoes at the beginning of the formation are much hotter than our speculation.
The finding is important to explain the origins of carbonate minerals on Mars, while also providing important evidence to help scientists find alien life.
