Deducing Lunar Regolith Porosity From Energetic Neutral Atom Emission
Wurz, P.; Galli, A.; Jäggi, N. +6 more
The porosity of the upper layers of regolith is key to the interaction of an airless planetary body with precipitating radiation, but it remains difficult to characterize. One of the effects that is governed by regolith properties is Energetic Neutral Atom (ENA) emission in the form of reflected and neutralized solar wind protons. We simulate this…
Dielectric Constant Estimation of Lunar Surface Using Mini-RF and Chandrayaan-2 SAR Data
Kumar, Raj; Das, Anup; Putrevu, Deepak +4 more
Dielectric characterization and polarimetric analysis of lunar north polar crater Hermite-A using Chandrayaan-1 Mini-SAR, Lunar Reconnaissance Orbiter (LRO) Mini-RF, and Chandrayaan-2 DFSAR data
Chauhan, Prakash; Singh, Awinash; Sharma, Aanchal +5 more
Studies of the lunar surface from Synthetic Aperture Radar (SAR) data have played a prominent role in the exploration of the lunar surface in recent times. This study uses data from SAR sensors from three Moon missions: Chandrayaan-1 Mini-SAR, Lunar Reconnaissance Orbiter (LRO) Mini-RF and Chandrayaan-2 Dual Frequency Synthetic Aperture Radar (DFS…
Chronological and compositional mapping of the Mare Orientale basin using Chandrayaan-1 - M3 and LRO datasets
Karthi, A.; Arivazhagan, S.
The lunar multiring mare basins have different ages, compositions and are associated with the diverse unit of mare deposits, providing evidence for the origin and evolution of the lunar crust. The multiring basins offer the opportunity to assess many unknown questions that may reveal the lunar geologic standpoint. The Mare Orientale basin is one o…
New view of the Balmer-Kapteyn region: Cryptomare distribution and formation
Li, Fei; Yan, Jianguo; Gao, Wutong +4 more
Context. The cryptomare in the Balmer-Kapteyn region is the oldest one on the Moon. Determining the extent and formation of this feature can deepen our understanding of early mare volcanism and help establish temporal and spatial constraints on lunar thermal and volcanic history.
Aims: This paper focuses on the identification of lunar cryptom…
An Investigation on the Morphological and Mineralogical Characteristics of Posidonius Floor Fractured Lunar Impact Crater Using Lunar Remote Sensing Data
Salem, Imen Ben; Sharma, Manish; Kumaresan, P. R. +4 more
Lunar floor-fractured craters (FFCs) are a distinguished type of crater found on the surface of the Moon with radial, concentric, and/or polygonal fractures. In the present study, we selected the Posidonius FCC to explore the mineralogy, morphology and tectonic characteristics using remote sensing datasets. The Posidonius crater is vested with a w…
Geology of the Crüger-Sirsalis Basin: Evidence for prolonged volcanism in the southwestern near side of the Moon
Bhatt, Megha; Bhardwaj, Anil; Srivastava, Neeraj +1 more
The Pre-Nectarian Crüger-Sirsalis Basin (centered at 16.0°S, 293.0°E; ~ 475 km in diameter) is a primarily degraded and obscured impact basin on the Moon. This study presents the first geological description of the Crüger-Sirsalis Basin using remote sensing datasets from Lunar Reconnaissance Orbiter (LRO), Chandrayaan-1, and Kaguya missions. An in…
Mapping of Compositional Diversity and Chronological Ages of Lunar Farside Multiring Mare Moscoviense Basin: Implications to the Middle Imbrian Mare Basalts
Sharma, Manish; Karthi, A.; Arivazhagan, S.
The Mare Moscoviense is an astonishing rare flatland multi-ring basin and one of the recognizable mare regions on the Moon's farside. The mineralogical, chronological, topographical and morphological studies of the maria surface of the Moon provide a primary understanding of the origin and evolution of the mare provinces. In this study, the Chandr…
Photometric Correction of Images of Visible and Near-Infrared Bands from Chandrayaan-1 Hyper-Spectral Imager (HySI): HySI Photometric Correction
Lala, Mili Ghosh Nee; Bose, Subhadyouti; Krishna, Akhouri Pramod
Photometric correction is a necessary step in planetary image pre-processing since the images of planetary surfaces are acquired by orbiting spacecraft at various observational geometries. In this study, visible (748 nm) and near-infrared (948 nm) bands of Hyper Spectral Imager (HySI) onboard Chandrayaan-1 have been used to derive a preliminary ph…
Petrological and Mineralogical Characteristics of Exposed Materials on the Floors of the Lavoisier and Surrounding Craters
Moon, Seulgi; Yi, Eung Seok; Kim, Kyeong Ja +3 more
Five floor-fractured craters (FFCs), Lavoisier crater and four craters surrounding it (Lavoisier C, Lavoisier E, Lavoisier F, and Lavoisier H), are distributed along the boundary between the northwestern part of the Oceanus Procellarum and the highlands. This study examines the uplifted or exposed materials on the fractured floors of these five im…
