A new view on the solar wind interaction with the Moon
Barabash, Stas; Holmström, Mats; Futaana, Yoshifumi +9 more
Characterised by a surface bound exosphere and localised crustal magnetic fields, the Moon was considered as a passive object when solar wind interacts with it. However, the neutral particle and plasma measurements around the Moon by recent dedicated lunar missions, such as Chandrayaan-1, Kaguya, Chang'E-1, LRO, and ARTEMIS, as well as IBEX have r…
Constraints on the depths of origin of peak rings on the Moon from Moon Mineralogy Mapper data
Head, James W.; Baker, David M. H.
Important to understanding the process of basin formation on planetary bodies are constraints on the mineralogy and depths of origin of interior ring structures. We summarize previous analyses of the mineralogy of basin materials on the Moon and use hyperspectral image-cubes from the Chandrayaan-1's Moon Mineralogy Mapper (M3) to determ…
In situ optical measurements of Chang'E-3 landing site in Mare Imbrium: 1. Mineral abundances inferred from spectral reflectance
Xiao, Long; Di, Kaichang; Yuan, Ye +11 more
The visible and near-infrared imaging spectrometer on board the Yutu Rover of Chinese Chang'E-3 mission measured the lunar surface reflectance at a close distance (~1 m) and collected four spectra at four different sites. These in situ lunar spectra have revealed less mature features than that measured remotely by spaceborne sensors such as the Mo…
Exploring the Moon's surface for remnants of the lunar mantle 1. Dunite xenoliths in mare basalts. A crustal or mantle origin?
Shearer, Charles K.; Burger, Paul V.; Bell, Aaron S. +2 more
Remotely sensed observations from recent missions (e.g., GRAIL, Kaguya, Chandrayaan-1) have been interpreted as indicating that the deep crust and upper mantle are close to or at the lunar surface in many large impact basins (e.g., Crisium, Apollo, Moscoviense). If this is correct, the capability of either impact or volcanic processes to transport…
Multiple origins for olivine at Copernicus crater
Head, James W.; Dhingra, Deepak; Pieters, Carle M.
Multiple origins for olivine-bearing lithologies at Copernicus crater are recognized based on integrated analysis of data from Chandrayaan-1 Moon Mineralogy Mapper (M3), Lunar Reconnaissance Orbiter (LRO) Narrow Angle Camera (NAC) and Kaguya Terrain Camera (TC). We report the diverse morphological and spectral character of previously kn…
Corrigendum to "The Sunlit lunar atmosphere: A Comprehensive study by CHACE on the Moon Impact Probe of Chandrayaan-1" [Planet. Space Sci. 58 (2010) 1567-1577]
Sridharan, R.; Ahmed, S. M.; Sreelatha, P. +4 more
The authors regret, an inadvertent error that could creep in while one attempts to estimate the number densities based on the reported lunar atmospheric composition data from the CHACE measurements in CHANDRAYAAN-1, the first Indian mission to the moon has been identified.
Detection of hydroxyl-bearing exposures of possible magmatic origin on the central peak of crater Theophilus using Chandrayaan-1 Moon Mineralogy Mapper (M3) data
Chauhan, Mamta; Bhattacharya, Satadru; Chauhan, Prakash +3 more
High-resolution spectral and spatial data analyses of crater Theophilus revealed the presence of hydroxyl-bearing exposures of possible magmatic origin on its central peak in association with olivine-, spinel- and crystalline plagioclase-bearing lithologies. Hydroxyl-bearing lithologies at Theophilus central peak are characterized primarily by a p…
Study of olivine-rich dark halo crater - Beaumont L in Mare Nectaris using high resolution remote sensing data
Chauhan, Prakash; Rajawat, A. S.; Kumar, A. S. Kiran +1 more
Study of dark-haloed craters (DHCs) can provide important information about the geology, mineralogy and evolution of certain hidden mare deposits known as cryptomare. Some DHCs have been identified in the Mare Nectaris region of the near side of the Moon. Beaumont L represents one such DHC situated on the western flank of the Nectaris basin. Moon …
Simulating charge transport to understand the spectral response of Swept Charge Devices
Narendranath, S.; Sreekumar, P.; Athiray, P. S. +1 more
Context. Swept Charge Devices (SCD) are novel X-ray detectors optimized for improved spectral performance without any demand for active cooling. The Chandrayaan-1 X-ray Spectrometer (C1XS) experiment onboard the Chandrayaan-1 spacecraft used an array of SCDs to map the global surface elemental abundances on the Moon using the X-ray fluorescence (X…
Circular Polarization Characteristics of South Polar Lunar Craters using Chandrayaan-1 Mini-SAR and LRO Mini-RF
Calla, Om Prakash Narayan; Mathur, Shubhra; Jangid, Monika +1 more
The paper presents a case study of inconsistent behaviour of Chandrayaan-1 Mini-SAR and LRO Mini-RF data over south polar lunar craters. The paper includes analysis of Stokes parameters and characterization of received time-varying electromagnetic fields over the south pole lunar craters. For the study, Chandrayaan-1 Mini-SAR and LRO Mini-RF data …
