These minerals, known as kaolinite, are rich in aluminum and poor in iron and magnesium.<\/p><p>\r\nThis composition indicates that they were formed not by hot, temporary water (like that from volcanoes or meteorite impacts), but by persistent rainfall and moderate temperatures over thousands or even millions of years.\r\n<\/p><p>\r\nDuring the Noachian epoch (between 4.1 and 3.7 billion years ago), Mars underwent a period of numerous asteroid impacts, which created large basins such as Hellas and Argyre.<\/p><p>\r\nDespite this violence, there is clear evidence of rivers, lakes, deltas, and valleys carved by water.<\/p><p>\r\nResearchers compared Martian clays with similar formations on Earth from periods when the climate was warm and humid, such as during greenhouse periods.\r\n<\/p><p>\r\nAlthough the Sun was about 30% weaker at that time, a thick atmosphere rich in greenhouse gases could have kept the planet warm enough to allow for abundant liquid water.<\/p><p>\r\nData from Perseverance suggest that, at least in some regions, Mars experienced prolonged humid periods, possibly the most habitable in its entire history.\r\n<\/p><p>\r\nThese favorable conditions coincide with the recent discovery of possible biological signals in the same location.<\/p><p>\r\nSamples collected by the rover are being stored for a future mission to bring them back to Earth-although that mission has been canceled by NASA, which could delay the analyses for many years.\r\n<\/p><p>\r\nJust imagine: billions of years before the first humans existed, what is now a cold and windy desert may have been a tropical environment, with flowing rivers and, who knows, primitive life forms.<\/p><p>\r\nThis new perspective makes Mars even more fascinating and reinforces the importance of continuing to explore the red planet to better understand its past and our own.\r\n<\/p><p>\r\n<iframe loading=\"lazy\" width=\"100%\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/vwXo-G-26TM\" title=\"Ancient Mars may have been warm, wet, and possibly inhabited\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><hr>\r\n\r\n<p style=\"text-align:right\"><em>Published in 04\/02\/2026 18h28<\/em><\/p>\r\n<hr>\r\n<p style=\"text-align:right\"><em><a href=\"https:\/\/terrarara.com.br\/?page_id=26628\">Portuguese version<\/a><\/em><\/p>\r\n<hr>\r\n\r\n\t\t<p>Text adapted by AI (Grok) and translated via Google API in the English version.
