ʻO ka mea hana APXC ma luna o ka lunar rover o ka ISRO's Chandrayaan-3 moon mission i hana ʻia i loko o kahi spectroscopic study e ʻike i ka nui o nā mea i loko o ka lepo a puni ka pae ʻāina ma ka ʻāpana polar hema o ka mahina. ʻO kēia ka haʻawina mua loa o ka haku mele ma ka ʻāina mahina ma ka ʻāina polar hema (ua nānā nā haʻawina mua i ka haku ʻāina ma nā ʻāpana equatorial a i waena o ka latitu). Hōʻike nā ʻike i ka like ʻole o ka haku ʻana i ka lepo lunar. ʻO Ferroan Anorthosite (FAN) pōhaku, waiwai i ka mineral plagioclase ka nui. He huahana kēia o ka crystallization lunar magma moana (LMO). Ua ʻike ʻia ka nui o nā minerala waiwai nui o ka magnesium e hōʻike ana i ka hāʻawi ʻana mai ka papa hohonu o ka mahina. Ma ke ʻano holoʻokoʻa, kākoʻo kēia haʻawina i ke kuhiakau Lunar Magma Ocean (LMO) o ka ulu ʻana o ka mahina.
Ua hōʻike ʻo ISRO's Chandrayaan-3 moon mission i ka hiki ke pae ʻana i ka mahina ma ka lā 23 ʻAukake 2023 i ka wā i iho ai kona pae ʻāina ma ka ʻili o ka mahina ma kahi kokoke i ka pole hema ma ka latitu Hema 69.37-degere a me ka longitude Hikina 32.35-degree (ma hope i kapa ʻia ʻo Shiv Shakti point).
Ua ʻimi ka rover i kau ʻia ma kahi kokoke e hele ana ma kahi o 103 mau mika no nā lā he ʻumi e hiki mai ana a hana i nā hoʻokolohua in-situ me ka hoʻohana ʻana i ka mea kani Alpha Particle X-ray Spectrometer (APXS) ma luna o ka rover.
Ua ana ka mikiona i ka haku mele ana o ka lepo o ka mahina ma na wahi e ku ai o ka rover ma o ka lawe ana i ka APXS mea pili kokoke i ka ilikai no ke ana ana a me ka waiho ana i hope i ka nee ana. Ua hoʻohana ʻia nā ʻano hana X-ray Fluorescence Spectroscopy a me Particle Induced X-ray Emission no ka ʻike ʻana a me ka helu ʻana i nā mea nui a me nā mea liʻiliʻi i loaʻa i ka lepo o ka mahina, e like me Si, Mg, Al, Fe, Ca, a me Mn, Cr, Ti, Ni, K, Na, a me, S, a pela aku. Ma ka hoohuoi ana i ka ili o ka mahina me kona mau kumu Cm-244, ua kakau APXS i na laina X-ray ano o na mea nui a me na mea liilii. Ua hana ka APXS i 23 mau ʻike ma ke ala o ka rover a loaʻa i kahi kikoʻī X-ray ma kēlā me kēia wahi.
ʻO kēia ka ana mua ma kahi o ka haku mele ʻana o nā mea i loko o ka lepo lunar ma nā ʻāpana latitu kiʻekiʻe hema o ka mahina. Ua hana ʻia nā haʻawina mua o nā ana o nā mea o ka lepo lunar me ka hoʻohana ʻana i nā laʻana i hōʻiliʻili ʻia mai ka equatorial a i ka waena waena o ka latitu e nā misionari ʻo Apollo, Luna a me Changʻe 5, nā meteorites lunar o kahi ʻike ʻole o kahi kumu a me nā ana in-situ mai ka waena. - nā ʻāpana latitude e nā misionari Changʻe 3 a me Changʻe 4.
Ua hōʻike ʻia ka nānā ʻana o ka ʻikepili APXS mai nā ana he 23 ma kēlā me kēia wahi kokoke i ke kahua pae ʻana i ke ʻano like ʻole o ka haku mele ma nā wahi i ʻimi ʻia e ka rover. ʻO ka lepo ka hui ʻana o nā ʻano pōhaku ʻelua. ʻO Ferroan Anorthosite (FAN) pōhaku, waiwai i ka mineral plagioclase he huahana ia o ka crystallization o ka moana pelemaka lunar (LMO). Ua ʻike pū ka mea hana APXS i ka nui o nā minerala waiwai nui o ka magnesium.
He mea koʻikoʻi ka ʻike o ka haku mele ʻana i ka ʻili o ka mahina no ka hoʻomaopopo ʻana i ke kūkulu ʻana a me ka ulu ʻana o ka mahina. Wahi a ka Lunar Magma Ocean (LMO) hypothesis, he moana holoʻokoʻa ka Moon o Magma i kinohi. Piʻolo nā mineral kaumaha a hoʻokumu i nā papa o loko i ka wā i maʻalili ai ka pelemaka. I ka manawa like, lana nā mineral māmā a hoʻokumu i ka ʻōpala waho o ka mahina.
ʻO ka mana nui o Ferroan Anorthosite (FAN) i ka lepo lunar ma ka pae pae ʻāina rover, ʻo ia ka ʻike nui o kēia noiʻi e kākoʻo ana i ke kuhiakau Lunar Magma Ocean (LMO). ʻO ka loaʻa ʻana o nā minerala waiwai magnesium e hōʻike ana i ka hui ʻana me nā minerala me ka papa o loko.

. Findings showed uniformity in composition lunar soil. Ferroan Anorthosite (FAN) rock, rich in plagioclase mineral was predominantly present. This a product of lunar magma ocean (LMO) crystallization. Abundance of magnesium-rich minerals was also detected suggesting contribution from the deeper layer of the Moon. Overall, this study supports Lunar Magma Ocean (LMO) hypothesis of evolution of the Moon.){kind=link}
