Abstract The Vastitas Borealis Formation is a Hesperian-aged sedimentary unit that mainly covers the Martian northern plains. Its environment of formation uncertain but may be related to an ancient ocean, outflow channel deposits, compaction and drainage activities, or subsurface ice-related processes. Here we investigate geological evolution using geochemical mineralogical data acquired by Mars Surface Composition Detector on board Zhurong rover at Tianwen-1 landing site. We find...
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...
An electroactive metal–organic framework film (NENU-3) onto a copper electrode has been prepared by the facile electrochemical plating strategy.
Abstract Searching for life on Mars can help us understand the origins and evolution of life, it has always been a primary scientific goal exploration missions by different countries. Raman spectroscopy numerous advantages in detecting materials, such as gathering chemical compositionand crystal structure, etc., specifically, ultraviolet which is especially suitable identifying organic compounds deployed Mars. In this study, an independent UV system builtto explore potential planetary...
A novel ZIF-Ni composite film has been successfully prepared by a facile method involving the in situ deposition of ZIF-8 on nickel porous which is fabricated selectively etching copper from dense Ni/Cu alloy film. The nanostructures resulting films are carefully examined combination scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis, Fourier transform infrared (FT-IR) spectroscopy, energy dispersive (EDX), and nitrogen adsorption-desorption. Cyclic voltammetric...
Abstract Chloride salts have been identified on the surface of Mars and Europa based results from two soil samples analyzed by Phoenix's wet chemistry laboratory for Mars, as well some interpretations data remote sensing Europa. To help elucidate our understanding Mars' Europa's mineral composition relevant environmental conditions, we studied a series magnesium chlorides with all six hydration degrees that were synthesized using various conditions. The identifications chloride hydrates...
Abstract Chlorine is one of the highly mobile elements that participated in early aqueous chemistry and later alteration Mars history. Our new experimental results suggest chlorine could cycle on present‐day between atmosphere surface, driven by multiphase redox plasma induced current Martian dust activity (dust storms, devils, grain saltation). We present two sets demonstrate instantaneous release from seven common chlorides during a medium strength electrostatic discharge (ESD) process...
Abstract Crystalline ferric sulfates (e.g., ferricopiapite and Fe(OH)SO 4 ) have been proposed at multiple locations on Mars by the orbiter. While Meridiani Planum Gale Crater rover missions, amorphous were also suggested to exist in soils sedimentary rocks. Ferric with different hydration degrees may play a key role water cycle Mars. In order understand of hydrated their exact states Mars, five crystalline seven synthesized laboratory. The content (number H 2 O molecules per sulfate...
Abstract Ordinary γ‐CaSO 4 is a metastable calcium sulfate, while from the hyperarid region on Earth and Mars has been found with abnormally high stability. In this study, we used multiple microanalyses to characterize chemical structural properties of two such : one Atacama soil (#10‐d30) other Martian meteorite MIL03346,168. Silicon was determined be quasi‐homogeneously distributed in , both silicon phosphorus were detected . We stability those environments due impurities which filled...
Abstract A high proportion of noncrystalline (X‐ray‐amorphous) components has been found in all samples analyzed by CheMin on the Curiosity rover at Gale crater Mars, and such X‐ray‐amorphous probably occur sites that have investigated thus far landers rovers. The amorphous material is rich volatiles (S, Cl, H 2 O), as indicated other science payload elements (APXS, SAM). We demonstrate here amorphization S Cl salts can be induced energetic electrons free radicals generated a medium‐strength...
Abstract Petrological and mineralogical analyses of Northwest Africa (NWA) 10720 indicate that this meteorite is one Martian nakhlite with an unbrecciated augitic igneous cumulate texture, consisting clinopyroxene (65.4 vol.%) olivine (19.4 set in a fine‐grained intercumulus matrix. Texturally compositionally, complex primary zoning cumulus augite the presence oscillatory phenocrysts NWA has experienced at least two‐stage magmatic activity before eruption. The first parental magmas nakhlites...
Magnesium sulfate has been widely detected on the surface of Mars. The occurrence magnesium and mixed cationic sulfates preserves clues regarding sedimentary environment, hydrological processes, climate history ancient In this study, seven double salts were synthesized in laboratory using a high-temperature solid phase reaction or slow evaporation aqueous solutions. samples analyzed X-ray diffraction to confirm their homogeneity. Subsequently, Raman, mid-infrared spectra, visible...
Different sulfates (Ca-, Mg, and Fe- sulfates) have been extensively detected on the Martian surface. As one of sulfates, presence ferrous will provide valuable clues about redox environment, hydrological processes, climatic history ancient Mars. In this study, three hydrated were prepared in laboratory by heating dehydration reactions. These samples analyzed using X-ray Diffraction (XRD) to confirm their phase homogeneity. Subsequently, Raman, mid-infrared (MIR) spectra, visible...
Abstract Akaganeite and jarosite were detected in two mudstone drill samples from Vera Rubin ridge (VRR), Gale crater by Chemistry & Mineralogy X‐Ray Diffraction (CheMin). The co‐occurrence of these minerals is quite rare both terrestrial Martian aqueous environments. In order to confine the chemical conditions paragenetic akaganeite jarosite, provide insight into late‐stage diagenetic alterations at VRR, we synthesized with varying SO 4 2− concentrations initial pH levels.
