The formation and distribution of lunar surficial water remains ambiguous. Here, we show the prominence (OH/H2O) attributed to solar wind implantation on uppermost surface olivine, plagioclase, pyroxene grains from Chang'E-5 samples. results spectral microstructural analyses indicate that wind-derived is affected by exposure time, crystal structure, mineral composition. Our estimate a minimum 170 ppm content in soils region consistent with reported Moon Minerology Mapper lander. By comparing...
The Zhurong rover of the Tianwen-1 mission landed in southern Utopia Planitia, providing a unique window into evolutionary history Martian lowlands. During its first 110 sols, investigated and categorized surface targets igneous rocks, lithified duricrusts, cemented soils sands. analysed by using laser-induced breakdown spectroscopy onboard Zhurong, show elevated water contents distinct compositions from those rocks. duricrusts are likely formed via vapor-frost cycling at atmosphere-soil...
Ferric iron as well magnetite are rarely found in lunar samples, and their distribution formation mechanisms on the Moon have not been studied. Here, we discover sub-microscopic particles Chang'E-5 soil. Magnetite pure metallic embedded oxygen-dissolved iron-sulfide grains from samples. This mineral assemblage indicates a FeO eutectoid reaction (4FeO = Fe3O4 + Fe) for of magnetite. The grains' morphology features oxygen's suggest that gas-melt phase occurred during large-impact events. could...
Abstract It is important to develop Martian soil simulants that can be used in Mars exploration programs and research. A new simulant, called Jining Soil Simulant (JMSS-1), was developed at the Lunar Planetary Science Research Center Institute of Geochemistry, Chinese Academy Sciences. The raw materials JMSS-1 are basalt Fe oxides (magnetite hematite). produced by mechanically crushing with addition small amounts magnetite hematite. properties this including chemical composition, mineralogy,...
Yutu-2 rover conducted an exciting expedition on the 41st lunar day to investigate a fin-shaped rock at Longji site (45.44°S, 177.56°E) by extending its locomotion margin perilous peaks. The varied encountered, especially multi-form wheel slippage, during journey target rock, established unique conditions for fin-grained regolith analysis regarding bearing, shear and lateral properties based terramechanics. Here, we show tri-aspect characterization of infer rock's origin using digital twin....
Abstract Mare basalts from lunar farside are pivotal for unraveling nearside-farside dichotomies and global thermal history. The Chang’e-6 (CE-6) mission conducted the first sampling a young basaltic unit within Apollo basin on farside. Here, we performed comprehensive petrological geochemical analyses CE-6 basalt clasts. is low-titanium (about 5 wt% TiO 2 ) depleted in KREEP components. absence of olivine, particularly magnesium-rich suggests that magma underwent extensive fractional...
Chang'E-6 lunar soil was the first sample collected on farside. It provides insights into impact history and thermodynamic evolution of Moon. Here we show discovered widespread oldhamite (CaS) in regolith samples. Analysis microscopic composition crystal structure showed that has a cubic presence at interface glass iron surface beads, suggesting thermochemical reaction. Thermodynamic calculations formation chemical reactions requires reducing atmosphere high temperature to ensure environment...
Abstract Lunar soil samples from young maria (formed <3.0 billion years ago (Ga)) preserve key records of recent space weathering history in the Earth–Moon system. China’s Chang’e-6 mission returned first farside a mare (∼2.8 Ga) at northeastern South Pole–Aitken basin. We present preliminary results on properties soils. The glassy agglutinate content soils is approximately 30%, significantly lower than 50%–70% observed mature Apollo older (>3.0 and higher ∼21% found Chang’e-5 younger...
Abstract Nanophase iron (np-Fe) particles in space-weathered lunar regolith are widely concerning as they can change the spectral, chemical, and physical properties of soils. These np-Fe were previously believed to be produced from surface materials by space weathering processes, while source exotic micrometeorite (flux = ∼5 × 10 8 t/Ma) has been overlooked. In this study, we report discovery impactor residue on a plagioclase crystal Chang’e-5 soil. Our results show that these does not...
Abstract Noachian‐aged Jezero crater, the landing site of Perseverance rover, recorded a fan‐delta system associated with fluvial‐lacustrine features, indicating past presence paleolake. However, collected targets at crater floor indicate that igneous units exhibit distinctive mineralogical including co‐occurrence different hydrated salts as evidence later alteration by fluids. In this work, we analyzed SHERLOC Raman spectra and micro‐images seven in upper fan unit during third science...
Context. Space weathering (SW) is crucial to improve the understanding of evolution optical characteristics on airless bodies. The classical view based research Moon suggests that SW decreases albedo (darkening) and steepens spectral slope (reddening) in visible near-infrared (VIS-NIR) wavelengths, producing nanophase iron (npFe 0 ). However, this conclusion not perfectly applicable asteroids. Aims. In study, we focus investigating space alteration effects (SWSAE) causes various types...
Abstract This study presents the petrography, mineralogy, and bulk composition of lunar regolith breccia meteorite Northwest Africa ( NWA ) 7948. We identify a range lithologies including basaltic clasts (very low‐titanium basalts), feldspathic (ferroan anorthosite, magnesian‐suite rock, alkali suite), granulites, impact melt breccias (including crystalline breccias, clast‐bearing glassy breccias), as well components (volcanic glass glass). A compositionally unusual metal‐rich clast was also...
Microwave sintering is regarded as a high-efficiency, energy-saving, and rapid-heating technique for the preparation of structural materials on Moon. However, influencing factors (i.e., ilmenite content temperature) microwave processes are not well-understood. Herein, five lunar regolith simulants with different contents 4.6%, 28.5%, 43.9%, 65.8%, 80.9% by weight) were used experiments at 1,050°C, 1,150°C, 1,300°C. The characterization microstructure, mineralogy, thermal conductivity,...
Abstract The diverse microstructures of Fe‐Ni metal in 10 L groups ordinary chondrites that experienced progressive shock alteration were investigated using the electron backscattered diffraction technique. Through a combination metallography and silicate‐based classification scheme, we established metamorphic features phases corresponding to particular impact stages. In weakly shocked (S1–S2), interlaced Neumann bands occur polycrystalline kamacite, resulting from multiple small events on...
Abstract Lunar glasses are characterized by complex origin (i.e., volcanism or impact), compositional diversity (e.g., picritic, basaltic, feldspathic), and visible/near‐infrared spectra similarity. This makes it is problematic to distinguish different types of lunar in laboratory remote data. In this study, we present micro‐FTIR (Fourier Transform Infrared) spectroscopy (550–1450 cm –1 ) a suite volcanic pyroclastic glasses) impact‐generated mare highland impact glasses), identified breccia...
Abstract Lunar breccias preserve the records of geologic processes on Moon. In this study, we report occurrence, petrography, mineralogy, and significance observed secondary olivine veinlets in lunar feldspathic breccia meteorite Northwest Africa ( NWA ) 11273. Bulk‐rock composition measurements show that is geochemically similar to other highland meteorites. 11273, five clasts are host dominated by interconnecting mineral grains. The mainly composed mafic minerals (i.e., pyroxene olivine)...
Abstract The temporal duration of lunar‐evolved magmatism is still poorly constrained. In lunar meteorite Northwest Africa (NWA) 10049, a melt inclusion‐bearing zircon fragment provides new tool to understand the composition and age melts from which directly crystallized. studied zircon‐hosted inclusions are silica rich iron poor (e.g., ~80–90 wt% SiO 2 ; <0.5 FeO), compositionally similar with immiscible silica‐rich found in Apollo rocks. Nano‐SIMS U–Pb analyses yielded minimum...
