The moon strike escaped real-time detection by telescopes on Earth and in space.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"Two side-by-side images show the surface of the moon with and without the crater.\"   src=\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/09\/1789677611_645_default.jpg\" style=\"aspect-ratio:2.0197693574958815\" data-cy=\"image-img\"\/>A zoomed-in view of McGetchin Crater, circled on the left, next to a &#8216;before&#8217; image on the right. (NASA Goddard\/Intuitive Machines\/Robert Wagner)<\/p>\n<p>LRO&#8217;s wide-angle images were not identified in the crush of data until August 2025. The spacecraft gathered more detailed pictures last fall, followed by confirmation of the discovery early this year.<\/p>\n<p>The crater is named for the late Thomas McGetchin, a former director of Houston&#8217;s Lunar and Planetary Institute.<\/p>\n<p>Like gardening<\/p>\n<p>Pockmarked since ancient times, the moon bears some of the solar system&#8217;s largest impact craters, including one that stretches more than 2,400 kilometres across.<\/p>\n<p>This latest impact churned the lunar surface for more than 100 kilometres. Dust and rocky soil were hurled away at a higher angle than expected, according to Mark Robinson, chief scientist for the LRO&#8217;s cameras who works at Intuitive Machines. Robinson was the lead author for one of the studies.<\/p>\n<p>A separate study identified a seven-kilometre-wide cold spot around the new crater, consistent with a loosening of the moon&#8217;s topsoil. Co-author David Paige of the University of California, Los Angeles, likens it to gardening.<\/p>\n<p>&#8220;We&#8217;re now thinking of impacts as a way to garden the regolith \u2014 churning the sediments and putting stuff above that&#8217;s usually below the surface,&#8221; Paige said in a statement. (Regolith is the term for the loose, solid material on top of bedrock.)<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"An overhead view shows a crater on the moon with bright ejecta surrounding it.\"   src=\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/09\/1789677612_146_default.jpg\" style=\"aspect-ratio:1.0009775171065494\" data-cy=\"image-img\"\/>An overhead, close-up view of McGetchin Crater that was taken on Dec. 5, 2025, by NASA&#8217;s Lunar Reconnaissance Orbiter.
