This was confirmed when one meteorite was dated to be <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/nature12764\">4.4 billion years old<\/a>. Properties of some other Martian meteorites show Mars <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/nature00982\">formed within 13 million years<\/a> of the formation of the Solar System. This in turn means some of the first planetary crust that formed on Mars likely still exists at the surface.<\/p>\n<figure class=\"align-center \">\n<figure class=\"post-image post-mediaBleed aligncenter\"><img loading=\"lazy\" decoding=\"async\" sizes=\"auto, (min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px\" alt=\"Martian meteorite\" width=\"600\" height=\"555\" class=\" lazy\" src=\"https:\/\/images.theconversation.com\/files\/385154\/original\/file-20210218-12-1tml0a5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\" data-lazy=\"true\" srcset=\"https:\/\/images.theconversation.com\/files\/385154\/original\/file-20210218-12-1tml0a5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=555&amp;fit=crop&amp;dpr=1 600w, https:\/\/images.theconversation.com\/files\/385154\/original\/file-20210218-12-1tml0a5.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=555&amp;fit=crop&amp;dpr=2 1200w, https:\/\/images.theconversation.com\/files\/385154\/original\/file-20210218-12-1tml0a5.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=555&amp;fit=crop&amp;dpr=3 1800w, https:\/\/images.theconversation.com\/files\/385154\/original\/file-20210218-12-1tml0a5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=697&amp;fit=crop&amp;dpr=1 754w, https:\/\/images.theconversation.com\/files\/385154\/original\/file-20210218-12-1tml0a5.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=697&amp;fit=crop&amp;dpr=2 1508w, https:\/\/images.theconversation.com\/files\/385154\/original\/file-20210218-12-1tml0a5.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=697&amp;fit=crop&amp;dpr=3 2262w\"\/><figcaption><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/thenextweb.com\/space\/2021\/02\/19\/what-weve-learned-about-the-red-planet-from-260-martian-meteorites-syndication\/#\" data-url=\"https:\/\/twitter.com\/intent\/tweet?url=https%3A%2F%2Fthenextweb.com%2Fspace%2F2021%2F02%2F19%2Fwhat-weve-learned-about-the-red-planet-from-260-martian-meteorites-syndication%2F&amp;via=thenextweb&amp;related=thenextweb&amp;text=Check out this picture on: Some Martian meteorites capture samples of the red planet\u2019s atmosphere in gas bubbles.
