A team of researchers, led by <a href=\"https:\/\/profiles.ucalgary.ca\/benjamin-tutolo\" target=\"_blank\" rel=\"noopener\" title=\"\">Dr. Ben Tutolo<\/a> from the <a href=\"https:\/\/www.ucalgary.ca\/\" target=\"_blank\" rel=\"noopener\" title=\"\">University of Calgary<\/a>, analyzed data collected by Curiosity from <a href=\"https:\/\/science.nasa.gov\/resource\/a-guide-to-gale-crater\/\" target=\"_blank\" rel=\"noopener\" title=\"\">Gale Crater<\/a>. Their findings, published in <em>Science<\/em> (<a href=\"https:\/\/www.science.org\/doi\/10.1126\/science.ado9966\" target=\"_blank\" rel=\"noopener\" title=\"\">1<\/a>, <a href=\"https:\/\/www.science.org\/doi\/10.1126\/science.adw4889\" target=\"_blank\" rel=\"noopener\" title=\"\">2<\/a>), revealed traces of siderite, an iron carbonate, embedded in sulfate-rich layers of <a href=\"https:\/\/science.nasa.gov\/resource\/the-making-of-mount-sharp\/\" target=\"_blank\" rel=\"noopener\">Mount Sharp<\/a>. This discovery could help scientists understand how Mars\u2019 atmosphere and climate evolved.<\/p>\n\n\n\n<p class=\"\">Siderite, a mineral that forms in environments with high levels of carbon dioxide (CO<sub>2<\/sub>), suggests Mars once had a CO<sub>2<\/sub>-rich atmosphere capable of sustaining liquid water. The presence of siderite also implies that the planet underwent a significant climate transition, shifting from a warm and wet environment to the cold and dry conditions seen today. This change may have been driven by the sequestration of CO<sub>2<\/sub> into rock, with the carbonates forming as the atmosphere thinned.<\/p>\n\n\n\n<p class=\"\">The study reveals that the Martian climate was likely much more habitable in the past, supporting liquid water on the surface. As Curiosity continues to explore Gale Crater, scientists are also studying other regions of Mars for similar mineral deposits that could offer more clues about the planet\u2019s early history. Dr. Tutolo and his team believe that understanding these processes could help us better understand how Mars transitioned from a potentially habitable planet to one that is now inhospitable.<\/p>\n\n\n\n<p class=\"\">The findings are also relevant for Earth scientists, as they parallel efforts to mitigate climate change. Tutolo noted that studying the mechanisms of carbon sequestration on Mars could offer insights into how humans might use similar processes to manage CO<sub>2<\/sub> on Earth. \u201cLearning from Mars shows us how fragile habitability can be,\u201d he said. Understanding how small changes in CO2 affect Mars may help us protect Earth\u2019s habitability for the future.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 id=\"references\" class=\"wp-block-heading\">References<\/h1>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">University of Calgary.
