Conventional methods for investigating heavy metal contamination in soil are time consuming and expensive. In this study, we (i) explored reflectance spectroscopy as an alternative method assessing metals, (ii) further the physicochemical mechanism that allows estimation of metals with method. We first investigated spectral response changing concentrations soils. The results indicated only at very high concentration can transition elements exhibit their inherent absorption features. spite...
Until recently, global high spatial resolution maps of FeO and TiO 2 the Moon were only derived from Clementine data. In this study, we show using Chang'E‐1 Interference Imaging Spectrometer (IIM) at a 200 m/pixel. With newly developed calibration presented here, spectra obtained by IIM compare well with telescopic spectra. Spectral parameters previously shown to be sensitive iron titanium, calibrated data are highly correlated measured elemental concentration R = 0.96 for 0.95 . The...
Abstract Whether or not background secondary craters dominate populations of small impact on terrestrial bodies is a half‐century controversy. It has been suggested that some planetary are dominated by based partly the steepened slope crater size‐frequency distribution (CSFD) toward diameters, such as less than ~1 km diameter population lunar mare. Here we show topography degradation enlarges and increases CSFD slopes with time. When taken into account, for various‐aged populations, observed...
Abstract How bright the Moon is forms a simple but fundamental and important question. Although numerous efforts have been made to answer this question such as use of sophisticated electro-optical measurements suggestions for calibration sites, still debated. An in situ measurement with panel on surface crucial obtaining accurate absolute reflectance resolving debate. China’s Chang’E-3 (CE-3) “Yutu” rover accomplished type using Visible-Near Infrared Spectrometer (VNIS). The VNIS, which were...
Abstract The long-period comets' perihelion places them near the sun so they may exhibit activity. Before 2013 LU28 reached perihelion, we performed a continuous observation to detect possible Using Lijiang 2.4 m telescope with Johnson R filter, measured brightness of from 2024 January 3 April 13. instrumental magnitudes were subsequently transformed into Pan-STARR r system. Due noticeable descending trend in absolute magnitude, verified cometary activity and constrained some photometric...
Abstract Exploring low-velocity collisions is crucial for unraveling intricate processes in planetary formation, particularly the bouncing barrier that impedes aggregation of dust into sizable planetesimals. Observational data on extraterrestrial collision remain limited. Here, we quantify parameters millimeter-sized lunar particles impacting porous surface at speeds ranging from 2.3 to 76.8 cm s −1 under gravity, leveraging Chang’E-4 imagery. This study represents first tangible acquisition...
In this article, we propose that reflectance spectroscopy or remote sensing technology is a rapid and inexpensive tool to monitor heavy-metal contamination in soils. We analyzed three data sets by both chemical methods. Despite the being obtained from different locations at times, all gave similar results; is, those were well correlated with Fe also had higher predictive accuracy: Ni, Cr, Co Baguazhou Island; Cu Jiangning County; Cu, As some areas of Island close correlations Fe, greater R2....
Abstract Submicroscopic metallic iron (SMFe) created by space weathering has strong effects on the optical properties of lunar surface. Spectra measured in situ visible‐near‐infrared spectrometer (VNIS) board Chang'E‐3 Yutu rover were used to investigate maturity differences at CE‐3 landing site caused lander exhaust. SMFe abundances estimated using Hapke's radiative transfer model. Analysis spectrum for a minimally disturbed soil indicates that it contains 0.368 wt % SMFe, corresponding an...
Abstract The last major phases of lunar volcanism occurred mainly in Oceanus Procellarum and Mare Imbrium produced spectrally unique medium‐ high‐titanium basalts. composition distribution these basalts provide a record the late stage thermal evolution Moon. To study spectral mineralogical variations mare basalts, 31 distinct units were mapped employing range remote sensing data. Their inferred characteristics studied by analyzing features small, fresh craters derived from Moon Mineralogy...
Aims . Studies on high-resolution and high-precision laboratory reflectance spectra of the Moon have historically been restricted to analysis old Apollo samples (>3.0 Ga). In contrast, studies young lunar soils exclusively relied remote sensing spectra. this study, we present results a spectral investigation (~2.0 Ga) obtained by Chang’E-5 (CE-5) mission. Methods We analyzed surficial subsurface collected through scooped drilled sampling methods. The CE-5 were compared with those orbital...
