The implications of finding evidence for life beyond Earth are staggering. The \u201cbefore and after\u201d mark would punctuate human history.<\/p>\n<p><a href=\"https:\/\/thenextweb.com\/topic\/mars\" target=\"_blank\" rel=\"noopener noreferrer\">Mars<\/a> is currently the most popular exploration target to search for evidence of life elsewhere. Yet little is known about its early history. <a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.abl7497\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Our research on a Martian meteorite<\/a> provides new clues about early surface conditions on the red planet.<\/p>\n<h2>Windows into the past<\/h2>\n<p>Today Mars is cold and inhospitable. But it may have been more Earth-like and habitable in a bygone era. Landforms on Mars record the action of liquid surface water, perhaps as early as 3.9 billion years ago.<\/p>\n<p>Like Earth, early Mars was subject to a global bombardment from chunks of rock and ice floating around the Solar System. Giant impacts both destroy and create favorable environments for life. So to untangle when conditions suitable for life may have arisen on Mars, we have to track the history of both water and impacts.<\/p>\n<p>A flotilla of rovers and orbiting spacecraft have been dispatched to Mars, with two <a href=\"https:\/\/solarsystem.nasa.gov\/missions\/mars-2020-rover\/in-depth\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">NASA rovers specifically exploring impact craters<\/a> for evidence of past life. Samples collected by rovers will be returned in future missions.<\/p>\n<p>For now, meteorites are the only samples of Mars available to study here on Earth. Martian meteorites are born when an impact on Mars ejects rocky fragments that later intercept Earth\u2019s orbit. Most Martian meteorites are igneous rocks, such as basalt. One meteorite, NWA 7034, is different, as it represents a rare sample of the surface of Mars.<\/p>\n<figure class=\"align-center zoomable\" readability=\"2\">\n<p><figure class=\"post-image post-mediaBleed aligncenter\"><a href=\"https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\" sizes=\"(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px\" alt width=\"600\" height=\"316\" class=\"js-lazy\" data-srcset=\"https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=1 600w, https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=2 1200w, https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=3 1800w, https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=1 754w, https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=2 1508w, https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=3 2262w\"><noscript><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\" alt width=\"600\" height=\"316\" class srcset=\"https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=1 600w, https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=2 1200w, https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=3 1800w, https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=1 754w, https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=2 1508w, https:\/\/images.theconversation.com\/files\/443681\/original\/file-20220201-25-tnll3f.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=3 2262w\"><\/noscript><\/a><figcaption><a href=\"https:\/\/thenextweb.com\/news\/newly-discovered-mars-zircon-may-hold-the-secret-to-life#\" data-url=\"https:\/\/twitter.com\/intent\/tweet?url=https%3A%2F%2Feditorial.thenextweb.com%2Fspace%2F2022%2F02%2F07%2Fnewly-discovered-mars-zircon-may-hold-the-secret-to-life%2F&amp;via=thenextweb&amp;related=thenextweb&amp;text=Check out this picture on: Meteorite NWA 7034 has been dubbed \u2018Black Beauty.\u2019 Image: Carl Agee\" data-title=\"Share Meteorite NWA 7034 has been dubbed \u2018Black Beauty.\u2019 Image: Carl Agee on Twitter\" data-width=\"685\" data-height=\"500\" class=\"post-image-share popitup\" title=\"Share Meteorite NWA 7034 has been dubbed \u2018Black Beauty.\u2019 Image: Carl Agee on Twitter\"><i class=\"icon icon--inline icon--twitter--dark\"><\/i><\/a>Meteorite NWA 7034 has been dubbed \u2018Black Beauty.\u2019 Image: Carl Agee<\/figcaption><\/figure><figcaption><\/figcaption><\/p>\n<\/figure>\n<h2>Sending shock waves<\/h2>\n<p>The NWA 7034 meteorite, weighing about 320g, was found in the desert of northwest Africa and <a href=\"https:\/\/www.science.org\/doi\/full\/10.1126\/science.1228858\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">first reported in 2013<\/a>.

Zircon is a \u201cgeochronometer\u201d, meaning it records (and reveals to us) how much time has passed since it crystallized from magma. <a href=\"https:\/\/www.nature.com\/articles\/s41586-018-0222-z\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Prior studies of NWA 7034<\/a> found it contains the oldest known zircons from Mars \u2013 some up to 4.48 billion years old.<\/p>\n<p>Zircon is quite useful for studying meteorite impacts. It preserves microscopic damage caused by the passage of shock waves, and these \u201cshocked grains\u201d provide a solid record of impact. However, no zircons with definitive shock damage had been identified in previous studies of NWA 7034.<\/p>\n<p>NWA 7034 is similar to a type of sedimentary rock on Earth called conglomerate. In such rocks, every mineral can have a different origin. With that in mind, we set out to survey additional zircon grains in NWA 7034 to see if we could find any that recorded evidence of impact.<\/p>\n<p>We looked at more than 60 zircons, but found only one shocked grain. This means the impact occurred before the grain was mixed into the pile of fragments that became a rock.<\/p>\n<h2>Reassessing Mars\u2019s timelines<\/h2>\n<p>The type of shock features we found are called \u201cdeformation twins\u201d. High-pressure shock waves squeeze zircon like an accordion. This process can reorganize atoms within the crystal, to form a duplicated \u201ctwin\u201d of zircon, which we can detect.<\/p>\n<figure class=\"align-center zoomable\" readability=\"3\">\n<p><figure class=\"post-image post-mediaBleed aligncenter\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/images.theconversation.com\/files\/443690\/original\/file-20220201-20-94z008.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\" sizes=\"(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px\" alt width=\"600\" height=\"605\" class=\"js-lazy\" data-srcset=\"https:\/\/images.theconversation.com\/files\/443690\/original\/file-20220201-20-94z008.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=605&amp;fit=crop&amp;dpr=1 600w, https:\/\/images.theconversation.com\/files\/443690\/original\/file-20220201-20-94z008.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=605&amp;fit=crop&amp;dpr=2 1200w, https:\/\/images.theconversation.com\/files\/443690\/original\/file-20220201-20-94z008.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=605&amp;fit=crop&amp;dpr=3 1800w, https:\/\/images.theconversation.com\/files\/443690\/original\/file-20220201-20-94z008.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=760&amp;fit=crop&amp;dpr=1 754w, https:\/\/images.theconversation.com\/files\/443690\/original\/file-20220201-20-94z008.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=760&amp;fit=crop&amp;dpr=2 1508w, https:\/\/images.theconversation.com\/files\/443690\/original\/file-20220201-20-94z008.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=760&amp;fit=crop&amp;dpr=3 2262w\"><figcaption><a href=\"https:\/\/thenextweb.com\/news\/newly-discovered-mars-zircon-may-hold-the-secret-to-life#\" data-url=\"https:\/\/twitter.com\/intent\/tweet?url=https%3A%2F%2Feditorial.thenextweb.com%2Fspace%2F2022%2F02%2F07%2Fnewly-discovered-mars-zircon-may-hold-the-secret-to-life%2F&amp;via=thenextweb&amp;related=thenextweb&amp;text=Check out this picture on: Scanning electron image of a shocked zircon in the matrix of martian meteorite NWA 7034.

The original igneous host rock was ripped apart during impacts on Mars. The zircon is a broken fragment from a larger grain mixed in with the matrix of the meteorite.<\/p>\n<p>We do, however, know where shocked zircons like this are made. On Earth, shocked zircons with deformation twins are only found at impact craters. Moreover, they occur at all of Earth\u2019s largest asteroid strikes.<\/p>\n<p>Zircons with shock features have been found at Vredefort in South Africa, Sudbury in Canada, and Chicxulub in Mexico. The Mexican crater formed about 65 million years ago, and has been linked to the extinction of the dinosaurs. In this case, shocked zircons were one product of an impact large enough to cause a mass extinction.<\/p>\n<p>Prior studies cited an absence of shock features in zircon from NWA 7034 to indicate a decline in catastrophic impacts on Mars by 4.48 billion years. It was further proposed that habitable conditions existed as of 4.2 billion years ago.<\/p>\n<p>However, the shocked zircon we found crystallized 4.45 billion years ago. The shock event would have had to have occurred at least 30 million years after Mars had supposedly stopped being bombarded.<\/p>\n<h2>When exactly was the impact?<\/h2>\n<p>Although determining the precise age of impact is difficult, geochemical <a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.aap8306\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">studies of NWA 7034<\/a> reveal its main components were subject to meteorite impacts before roughly 4.3 billion years ago. In this scenario, the zircon may have been shocked during this time, somewhere between 4.3 and 4.45 billion years ago.<\/p>\n<p>Alternatively, it may have formed more recently, but before a decline in the rate of impacts earlier than 3 billion years ago. Both <a href=\"https:\/\/www.science.org\/doi\/10.1126\/science.1090544\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">landforms<\/a> and <a href=\"https:\/\/www.nature.com\/articles\/nature07097\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">water-bearing minerals<\/a> argue for early surface water on Mars, possibly by 3.9 to 3.7 billion years ago. This may be the best indicator for when habitable conditions existed.<\/p>\n<p>Our findings raise new questions about the early impact history of Mars. Determining the origin of the shocked zircon, and time of impact, will provide better context for interpreting the planet\u2019s history as archived in meteorite NWA 7034 \u2013 and potentially a timeframe for when conditions for life may have emerged.<!-- Below is The Conversation's page counter tag.
