The presence of hydrated phases in the soil and near-surface bedrock Gale Crater is thought to be direct evidence for water-rock interaction crater ancient past. Layered sediments over floor are have formed past epochs due sediment transport, accumulation, cementation through with fluids, observed strata water-bearing minerals record history these episodes. first data analysis Dynamic Albedo Neutrons (DAN) investigation on board Curiosity rover presented 154 individual points active mode...
В статье представлены результаты лабораторных испытаний селективного лазерного сплавления (СЛС) порошковых композиций имитаторов лунного реголита из земных пород габбро-диабаза и лабрадорита, которые имеют различные диапазоны фракционности. Показано, что композиции с узкими диапазонами фракционности размерами частиц 50…100 мкм 100…140 позволяют изготовить тестовые образцы достаточно хорошими свойствами параметрами относительно низкой пористости приемлемым воспроизведением заданной...
Abstract Data gathered with the Dynamic Albedo of Neutron (DAN) instrument onboard rover Curiosity were analyzed for variations in subsurface neutron flux and tested possible correlation local geological context. A special DAN observation campaign was executed, which 18 adjacent active measurements acquired every 0.75–1.0 m to search hydrogen content along a 15 traverse across geologic contacts between Sheepbed Gillespie Lake members Yellowknife Bay formation. It found that several subunits...
Abstract The Dynamic Albedo of Neutron (DAN) instrument on board the Mars Science Laboratory Curiosity rover acquired a series measurements as part an observational campaign Kimberley area in Gale crater. These observations were planned to assess variability bulk hydrogen and neutron‐absorbing elements, characterized chlorine‐equivalent concentration, geologic members formation surface materials exposed throughout area. During traverse area, drove primarily over “Smooth Hummocky” unit, unit...
The dosimeter Liulin-MO for measuring the radiation environment onboard ExoMars Trace Gas Orbiter (TGO) is a module of Fine Resolution Epithermal Neutron Detector (FREND). Here we present results from measurements charged particle fluxes, dose rates and estimation equivalent at TGO Mars science orbit, provided by May 2018 to June 2022. period covers declining minimum phases solar activity in 24th cycle rising phase 25th cycle. Compared are values galactic cosmic rays (GCR) obtained during...
Abstract The Dynamic Albedo of Neutrons instrument aboard the Mars Science Laboratory rover, Curiosity, has been used to map a stratigraphically conformable layer high‐SiO material in Gale crater. Previous work shown that this contains tridymite, high‐temperature/low‐pressure felsic mineral, interpreted have volcanic source rock. We describe several characteristics including orientation, extent, hydration, and geochemistry, consistent with volcaniclastic conformably deposited within...
Abstract This paper is Part II of a double‐paper series that presents the abundance water and chlorine along with other neutron‐absorbing elements in shallow subsurface Gale crater based on measurements by Dynamic Albedo Neutron (DAN) instrument onboard NASA's Curiosity rover. Initial results were represented as pixels map data products from both DAN active passive made 27‐km traverse rover, corresponding to mission period landing martian surface August 2012 through December 2021. In II,...
This overview presents the physical principles, design, measurement capabilities, and summary of planned operations autonomous detector radiation neutrons onboard rover at Mars (ADRON-RM) on surface Mars. ADRON-RM is a Russian project selected for joint European Space Agency-Roscosmos ExoMars 2020 landing mission. A compact passive neutron spectrometer, ADRON-RM, was designed to study abundance distribution water absorption elements (such as Cl, Fe, others) in martian subsurface along path...
ExoMars is a joint ESA - Rosscosmos program for investigating Mars. Two missions are foreseen within this program: one consisting of the Trace Gas Orbiter (TGO), that carries scientific instruments detection trace gases in Martian atmosphere and location their source regions, launched on March 14, 2016; other, featuring rover surface platform, with launch date 2022. In 2018 TGO was inserted into circular Mars science orbit 400 km altitude. The dosimetric telescope Liulin-MO measuring...
Abstract This paper presents estimates of the water and chlorine contents in subsurface Gale crater based on measurements by Dynamic Albedo Neutrons (DAN) instrument onboard NASA Curiosity rover. It is Part 1 a two‐paper series. Data derived both from DAN active passive are presented discrete surface areas (pixels) assuming homogeneous distribution within sensing depth (60 cm) along traverse shown that content hydrogen, reported as Water Equivalent Hydrogen, varies between almost zero...
Abstract We analyze spatially pervasive, light‐toned “halos” associated with fractures in a sedimentary unit (Stimson) of Gale crater, Mars, and report similar network halos discovered separate geologic group (Bradbury). Through dedicated active neutron measurement campaign, we provide independent confirmation the water‐rich nature these features. Together mineralogical geochemical data, features are consistent abundant hydrated amorphous silica (opal‐A). suggest that mineral assemblages...
Possible correlation is studied between Water Equivalent Hydrogen (WEH) in the Martian subsurface, as measured by DAN (Dynamic Albedo of Neutrons) instrument along Curiosity traverse, and presence hydrated minerals on surface, seen from orbit CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) onboard MRO (Mars Orbiter). Cross-analysis subsurface WEH values passive measurements with distribution over surface Gale crater according to Specialized Browse Product Mosaics performed...
