The moon has been a steadfast witness to solar system history, its heavily cratered surface recording innumerable collisions over the last 4 billion years. However, scientists rarely get a glimpse of the projectiles \u2013 usually asteroids or comets \u2013 that <a href=\"https:\/\/doi.org\/10.1016\/j.pss.2021.105201\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">form these craters<\/a>.

A deeper understanding of impact physics will go a long way in helping researchers interpret the barren landscape of the moon and also the effects impacts have on Earth and other planets.<\/p>\n<figure class=\"align-center zoomable\" readability=\"4\">\n<p><figure class=\"post-image post-mediaBleed aligncenter\"><a href=\"https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.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\/449029\/original\/file-20220228-17-8xi5dv.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=\"An image showing a large crater on the surface of the Moon.\" width=\"600\" height=\"403\" class=\"js-lazy\" data-srcset=\"https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=403&amp;fit=crop&amp;dpr=1 600w, https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=403&amp;fit=crop&amp;dpr=2 1200w, https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=403&amp;fit=crop&amp;dpr=3 1800w, https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=507&amp;fit=crop&amp;dpr=1 754w, https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=507&amp;fit=crop&amp;dpr=2 1508w, https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=507&amp;fit=crop&amp;dpr=3 2262w\"><noscript><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\" alt=\"An image showing a large crater on the surface of the Moon.\" width=\"600\" height=\"403\" class srcset=\"https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=403&amp;fit=crop&amp;dpr=1 600w, https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=403&amp;fit=crop&amp;dpr=2 1200w, https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=403&amp;fit=crop&amp;dpr=3 1800w, https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=507&amp;fit=crop&amp;dpr=1 754w, https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=507&amp;fit=crop&amp;dpr=2 1508w, https:\/\/images.theconversation.com\/files\/449029\/original\/file-20220228-17-8xi5dv.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=507&amp;fit=crop&amp;dpr=3 2262w\"><\/noscript><\/a><figcaption><a href=\"https:\/\/thenextweb.com\/news\/rocket-crashing-into-moon-good-thing-for-physics#\" data-url=\"https:\/\/twitter.com\/intent\/tweet?url=https%3A%2F%2Feditorial.thenextweb.com%2Fspace%2F2022%2F03%2F02%2Frocket-crashing-into-moon-good-thing-for-physics%2F&amp;via=thenextweb&amp;related=thenextweb&amp;text=Check out this picture on: The rocket is expected to crash into the large Hertzsprung crater \u2013 seen in the center of this photo \u2013 just out of view of Earth on the far side of the Moon.

But about two weeks after the impact, NASA\u2019s Lunar Reconnaissance Orbiter will begin to get glimpses of the crater as its orbit takes it above the impact zone. Once conditions are right, the <a href=\"https:\/\/www.lroc.asu.edu\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">lunar orbiter\u2019s camera<\/a> will start taking photos of the impact site with a resolution of about a 3 feet (1 meter) per pixel.

A vertical orientation will produce a more circular feature, whereas an asymmetric debris pattern might indicate more of a belly flop. Models suggest that the crater could be anywhere from around <a href=\"https:\/\/doi.org\/10.1016\/j.icarus.2017.08.018\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">30 to 100 feet (10 to 30 meters) in diameter and about 6 to 10 feet (2 to 3 meters) deep<\/a>.<\/p>\n<p>The amount of heat generated from the impact will also be valuable information. If observations can be made quickly enough, there\u2019s a possibility the <a href=\"https:\/\/www.diviner.ucla.edu\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">lunar orbiter\u2019s infrared instrument<\/a> will be able to detect glowing-hot material inside the crater. This could be used to calculate the total amount of heat from the impact.

Some of these effects can <a href=\"http:\/\/www.psrd.hawaii.edu\/CosmoSparks\/Dec18\/lunar-cold-spot-craters.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">extend for hundreds of times the radius of the crater<\/a>.<\/p>\n<h2>Why this is important<\/h2>\n<p>Impacts and crater formation are a <a href=\"https:\/\/doi.org\/10.1016\/j.icarus.2013.03.019\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">pervasive phenomenon<\/a> in the solar system.
