A suitcase-sized seismometer developed at Goddard Space Flight Center could become the first American device to endure the Moon\u2019s two-week polar darkness, a milestone in NASA\u2019s push toward a permanent lunar outpost.<\/p>\n

The lunar south pole is among the most extreme environments in the solar system. During each two-week night, temperatures plunge to -330 degrees Fahrenheit, cold enough to cause solder joints to fracture and lithium-ion batteries to fail. Until now, no American instrument has survived a full polar night and resumed normal operation. According to Mashable, that may soon change.<\/p>\n

The Lunar Environment Monitoring Station, or LEMS<\/a>, is a 66-pound autonomous seismometer currently undergoing thermal vacuum testing at NASA\u2019s Goddard Space Flight Center in Maryland. Engineers are cycling the hardware between +300\u00b0F and -330\u00b0F to simulate the temperature swings it would encounter between deep shadow and full sun at the lunar south pole. Based on those results, the project\u2019s lead systems engineer, Samantha Hicks<\/a>, is confident: \u201cNo American payload, as far as we know, has ever been able to say that they have survived the lunar south pole during its lunar night and been functional. We are on track to become the first U.S. payload to do that.\u201d<\/p>\n

Engineering the Interior<\/p>\n

The central challenge is not the exterior of the box, it is what happens inside. While the outer shell of LEMS must tolerate temperature extremes spanning more than 600 degrees Fahrenheit, the battery, autonomous computer, and core electronics are maintained within a far narrower band: between -22\u00b0F and +86\u00b0F. That internal stability is what allows the instrument to keep operating through the darkness.<\/p>\n

The key to achieving it is a thermal blanket known as Integrated MultiLayer Insulation, or IMLI<\/a>, developed by Colorado-based Quest Thermal Group. The material uses patented discrete spacer technology to reduce heat transfer across layers, and according to its manufacturer, offers 60 percent less heat leak per layer than conventional insulation. NASA has also modified the way LEMS charges its lithium-ion battery to prevent a degradation process known as lithium-ion plating, which begins below -30\u00b0C and prevents the battery from absorbing charge normally.<\/p>\n

If LEMS demonstrates that a small instrument can survive the polar night using only solar panels, batteries, and advanced insulation (without the nuclear heat sources used by earlier missions) it would establish a template for simpler and cheaper surface hardware in the future.<\/p>\n

Extending Apollo\u2019s Seismic Record<\/p>\n

LEMS is designed to fill a gap that has persisted since 1977, when the last Apollo-era seismometers ceased transmitting. Those instruments, placed at landing sites on the Moon\u2019s near side between 1969 and 1972, recorded deep tidal moonquakes caused by Earth\u2019s gravitational pull, shallower shrinkage quakes reaching magnitude 5.5 and lasting over 10 minutes, meteoroid strikes, and thermal events caused by surface rock expanding and contracting with the Sun. According to NASA, the Moon <\/a>continues to shrink as it cools (its diameter has decreased by roughly 150 feet over the past several hundred million years) and its crust continues to crack as a result.<\/p>\n

All Apollo instruments operated on the side of the Moon facing Earth. LEMS, positioned at the south pole, would provide seismic data from an entirely unmonitored region, including the far side, which generates seismic waves that travel through the lunar interior before reaching the instrument. That geometry could help scientists map structures in the Moon\u2019s mantle and crust that remain poorly understood. \u201cThere\u2019s a lot we don\u2019t know about the lunar interior because we only had the observations from the near side,\u201d said Naoma McCall, LEMS co-investigator and deployment lead.<\/p>\n

LEMS is a candidate for the Artemis IV mission, which is targeting a crewed landing at the lunar south pole as early as 2028, though NASA has not yet finalized the payload manifest. Deployment is designed for simplicity: one astronaut, three switch positions, two sensors buried in drilled holes nearby. Once set, the instrument is intended to run without intervention for up to two years.<\/p>\n","protected":false},"excerpt":{"rendered":"A suitcase-sized seismometer developed at Goddard Space Flight Center could become the first American device to endure the…\n","protected":false},"author":2,"featured_media":449604,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[85,46,141,145],"class_list":["post-449603","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-il","tag-israel","tag-science","tag-space"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/449603","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=449603"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/449603\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/449604"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=449603"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=449603"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=449603"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
