A lake that filled a volcanic crater with a radius of 154 kilometers billions of years ago could be a significant finding for the existence of life on Mars, the planet most similar to Earth in the solar system. Scientists said on Monday, December 8, that the lake being studied by NASA's Curiosity rover strengthens theories related to microbial life on this planet. According to Reuters, this new theory is based on data collected by the NASA rover since August 2012. Scientists discovered rock layers containing sedimentary deposits that were inclined towards the center of the volcanic crater. These rocks form a hill five kilometers high known as 'Sharp Mountain.' Researchers from the Curiosity rover said in a phone interview with reporters that the new information indicates that 'Sharp Mountain' did not exist around three and a half billion years ago when the volcanic crater was filled with water. John Grotzinger, a scientist at the California Institute of Technology, stated, 'The discovery of these sloped layers was completely unexpected. Sedimentology is the leading method for understanding Earth's layers. When oil companies collect and analyze seismic data in various locations, they look for sloped layers because the geometry and angles of these layers indicate the location of the rocks we are searching for.' The Curiosity rover discovered shortly after landing that Mars once had chemical elements and biological conditions suitable for microbial life. This finding was the primary goal of the rover's mission. The rover then moved towards 'Sharp Mountain' to find habitable niches. Scientists aimed to discover whether Mars had maintained suitable environmental conditions for life formation long enough, similar to Earth. Scientists still do not know how long it took for life to form on Earth. Michael Meyer, a NASA Mars program expert, said, 'The size of the lake in this volcanic crater, the duration of time, and the remnants of the water's path suggest that there may have been enough time for life to form and continue.' New studies that have not yet been published refer to a series of drought periods in the 'Gale' crater. These findings contradict the existing theory that considers Mars' warm weather periods to be short-lived and at the beginning of the planet's formation. The Curiosity rover has traveled eight kilometers on the surface of Mars since its landing in 2012.
