Scientists used pictures taken withMars Hand Lens Image and Mastcam, they observe rocks and minerals in Gale Crater. The researchers discovered sediments that they believe were deposited as a result of giant flash floods that occurred after Mount Sharp and Gale Crater first formed.

They believe that the floods caused a powerfulimpact of meteorites. This phenomenon led to the release of heat due to the melting of huge amounts of ice on the planet. As a result, carbon dioxide and methane were released, which combined with water vapor for a short time formed a warm and humid climate. This led to heavy rains across the planet.
At this time, the planet had the conditions necessaryto maintain liquid water on the surface - NASA is now testing whether life existed on the planet during this period. Now the task of the Perseverance rover, which will land on the surface of the Red Planet in February 2021, is to test this hypothesis.
