Over billions of years, tiny particles from Earth\u2019s atmosphere have landed in the lunar soil, creating a possible source of life-sustaining substances for future astronauts. But scientists have only recently begun to understand how these particles make the long journey from the earth to the moon and how long the process has been taking place.\r\n\r\nNew research from the <a href=\"http:\/\/www.rochester.edu\/\">University of Rochester<\/a>, <a href=\"https:\/\/doi.org\/10.1038\/s43247-025-02960-4\">published in <em>Nature Communications Earth and Environment<\/em><\/a>, shows that Earth\u2019s magnetic field may actually help guide atmospheric particles\u2014carried by solar wind\u2014into space, instead of blocking them. Because Earth\u2019s magnetic field has existed for billions of years, this process could have steadily moved particles from Earth to the moon over very long periods of time.\r\n\r\n\u201cBy combining data from particles preserved in lunar soil with computational modeling of how solar wind interacts with Earth\u2019s atmosphere, we can trace the history of Earth\u2019s atmosphere and its magnetic field,\u201d says <a href=\"https:\/\/www.pas.rochester.edu\/people\/faculty\/blackman_eric\/index.html\">Eric Blackman<\/a>, a professor in the <a href=\"https:\/\/www.pas.rochester.edu\/\">Department of Physics and Astronomy<\/a> and a distinguished scientist at URochester\u2019s <a href=\"https:\/\/www.lle.rochester.edu\/\">Laboratory for Laser Energetics<\/a> (LLE).\r\n\r\nThe findings suggest lunar soil may not only hold a long-term record of Earth\u2019s atmosphere but could be even more valuable than scientists once thought for future space explorers living and working on the moon.\r\n<h3><strong>Clues from lunar soil<\/strong><\/h3>\r\nSoil brought back to Earth by the Apollo missions in the 1970s has provided scientists important clues. Studies of these samples show that the moon\u2019s dusty surface\u2014called the regolith\u2014contains volatile substances such as water, carbon dioxide, helium, argon, and nitrogen. Some of these volatiles come from the sun\u2019s constant stream of charged particles, known as the solar wind. But the amounts\u2014especially of nitrogen\u2014are too high to be explained by solar wind alone.\r\n\r\nIn 2005, a team led by researchers from the University of Tokyo proposed that a portion of the volatiles may have come from Earth\u2019s atmosphere. They argued this could only happen during a time before Earth developed a magnetic field, since they assumed the magnetic field would prevent atmospheric particles from escaping into space.\r\n\r\nBut the URochester researchers found the process may work differently.\r\n<h3><strong>Simulating how Earth\u2019s atmosphere reached the moon<\/strong><\/h3>\r\nThe URochester team\u2014including <a href=\"https:\/\/www.pas.rochester.edu\/~shubhonkar_paramanick\/\">Shubhonkar Paramanick<\/a>, a graduate student in the <a href=\"https:\/\/www.sas.rochester.edu\/pas\/index.html\">Department of Physics and Astronomy<\/a> and a <a href=\"https:\/\/www.lle.rochester.edu\/education\/graduate-program\/horton-fellowship-program\/\">Horton Fellow<\/a> at the LLE; <a href=\"https:\/\/www.sas.rochester.edu\/ees\/people\/faculty\/tarduno_john\/index.html\">John Tarduno<\/a>, the William R. Kenan, Jr. Professor in the <a href=\"https:\/\/www.sas.rochester.edu\/ees\/index.html\">Department of Earth and Environmental Sciences<\/a>; and <a href=\"https:\/\/www.sas.rochester.edu\/pas\/people\/faculty\/carroll-nellenback_jonathon\/index.html\">Jonathan Carroll-Nellenback<\/a>, a computational scientist at the <a href=\"https:\/\/www.circ.rochester.edu\/\">Center for Integrated Research Computing<\/a> and an assistant professor in the Department of Physics and Astronomy\u2014used advanced computer simulations to model how and when the regolith might have acquired the elements found in the Apollo samples.\r\n\r\nThe researchers tested two scenarios. One modeled an \u201cearly Earth\u201d without a magnetic field and under a stronger solar wind. The other modeled a \u201cmodern Earth\u201d with its strong magnetic field and a weaker solar wind. The simulations showed that the particle transfer works best in the modern Earth scenario. In this case, charged particles from Earth\u2019s atmosphere are knocked loose by the solar wind and guided along Earth\u2019s magnetic field lines. Some of the field lines stretch far enough into space to reach the moon. Over billions of years, this funneling effect has helped tiny amounts of Earth\u2019s atmosphere settle on the lunar surface.\r\n<h3><strong>Preserving the past and supporting the future<\/strong><\/h3>\r\nThe long-term exchange of particles means the moon may hold a chemical record of Earth\u2019s atmosphere. Studying lunar soil could therefore give scientists a rare window into how Earth\u2019s climate, oceans, and even life evolved over billions of years.\r\n\r\nThe long-term, steady transfer of particles also suggests the lunar soil contains more volatiles than previously thought. Elements such as water and nitrogen could support a sustained human presence on the moon, reducing the need to transport supplies from Earth and making lunar exploration more feasible.\r\n\r\n\u201cOur study may also have broader implications for understanding early atmospheric escape on planets like Mars, which lacks a global magnetic field today but had one similar to Earth in the past, along with a likely thicker atmosphere,\u201d Paramanick says. \u201cBy examining planetary evolution alongside atmospheric escape across different epochs, we can gain insight into how these processes shape planetary habitability.\u201d\r\n\r\nThis work was funded in part by NASA and the National Science Foundation.","background_color":"#ffffff","width":"width-medium"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Earth\u2019s atmosphere may help support human life on the moon<\/title>\n<meta name=\"description\" content=\"New research shows that Earth\u2019s magnetic field has helped deliver atmospheric particles to the lunar surface over billions of years.\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.rochester.edu\/newscenter\/lunar-soil-surface-earth-atmospheric-particles-687602\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Earth\u2019s atmosphere may help support human life on the moon\" \/>\n<meta property=\"og:description\" content=\"New research shows that Earth\u2019s magnetic field has helped deliver atmospheric particles to the lunar surface over billions of years.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/www.rochester.edu\/newscenter\/lunar-soil-surface-earth-atmospheric-particles-687602\/\" \/>\n<meta property=\"og:site_name\" content=\"News Center\" \/>\n<meta property=\"article:published_time\" content=\"2025-12-11T18:13:48+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2025-12-15T21:18:46+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/www.rochester.edu\/newscenter\/wp-content\/uploads\/2025\/12\/fea-lunar-soil-surface-earth-atmospheric-particles-1200x630.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"1200\" \/>\n\t<meta property=\"og:image:height\" content=\"630\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"author\" content=\"Lindsey Valich\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"Lindsey Valich\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"1 minute\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"Article\",\"@id\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/lunar-soil-surface-earth-atmospheric-particles-687602\\\/#article\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/lunar-soil-surface-earth-atmospheric-particles-687602\\\/\"},\"author\":{\"name\":\"Lindsey Valich\",\"@id\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/#\\\/schema\\\/person\\\/fcd7d29a5b8e855924bf73b764dcd827\"},\"headline\":\"Earth\u2019s atmosphere may help support human life on the moon\",\"datePublished\":\"2025-12-11T18:13:48+00:00\",\"dateModified\":\"2025-12-15T21:18:46+00:00\",\"mainEntityOfPage\":{\"@id\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/lunar-soil-surface-earth-atmospheric-particles-687602\\\/\"},\"wordCount\":11,\"image\":{\"@id\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/lunar-soil-surface-earth-atmospheric-particles-687602\\\/#primaryimage\"},\"thumbnailUrl\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/wp-content\\\/uploads\\\/2025\\\/12\\\/fea-lunar-soil-surface-earth-atmospheric-particles.jpg\",\"keywords\":[\"Department of Earth and Environmental Sciences\",\"Department of Physics and Astronomy\",\"Eric Blackman\",\"John Tarduno\",\"Laboratory for Laser Energetics\",\"research finding\",\"School of Arts and Sciences\"],\"articleSection\":[\"Science &amp;
