Revera\u2009\/\u2009Wikimedia Commons <\/span><\/p><\/div>\n<p>Like a grape shriveling up into a raisin, the Moon is shrinking and becoming more wrinkled. However, because it is not made of flexible materials like a fruit, it is deforming more violently. The number of geological faults is rising, and earthquakes and landslides are becoming more frequent. As its core has cooled, the Moon&#8217;s circumference has shrunk by more than 45 meters over the past few hundred million years. Researchers from NASA and various North American universities and research institutes found that this lunar contraction has caused the emergence of tectonic faults at the Moon\u2019s south pole. Some of the regions affected by deformations and instability in the terrain are located in areas considered as landing sites for NASA\u2019s Artemis 3 mission, which is scheduled for 2026 and intends to take astronauts to the Moon once again. \u201cOur modeling suggests that shallow moonquakes capable of producing strong ground shaking in the south polar region are possible from slip events on existing faults or the formation of new thrust faults,\u201d said Tom Watters of the Smithsonian Institution, lead author of the paper, in a press release. He points out that this information should be taken into account when planning the location of potential future permanent outposts on the Moon (<em>The Planetary Science Journal<\/em>, January 25).<\/p>\n","protected":false},"excerpt":{"rendered":"Cooling of the Moon\u2019s core has caused it to shrink over the last few hundred million years","protected":false},"author":475,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[205],"coauthors":[785],"class_list":["post-515864","post","type-post","status-publish","format-standard","hentry","category-notes","tag-astronomy"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/515864","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=515864"}],"version-history":[{"count":1,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/515864\/revisions"}],"predecessor-version":[{"id":515873,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/515864\/revisions\/515873"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=515864"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=515864"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=515864"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=515864"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
