چکیده

The search for water on the surface of the anhydrous Moon had remained an unfulfilled quest for 40 years. However, the Moon Mineralogy Mapper (M3) on Chandrayaan-1 has recently detected absorption features near 2.8 to 3.0 micrometers on the surface of the Moon. For silicate bodies, such features are typically attributed to hydroxyl- and/or water-bearing materials. On the Moon, the feature is seen as a widely distributed absorption that appears strongest at cooler high latitudes and at several fresh feldspathic craters. The general lack of correlation of this feature in sunlit M3 data with neutron spectrometer hydrogen abundance data suggests that the formation and retention of hydroxyl and water are ongoing surficial processes. Hydroxyl/water production processes may feed polar cold traps and make the lunar regolith a candidate source of volatiles for human exploration.

Active moon: evidences from Chandrayaan-1 and the proposed Indian missions

Chandrayaan-1, the polar Lunar orbiter mission of Indian Space Research Organization, successfully carried out study of Moon’s environment and surface processes for a period of about nine months during 2008–2009. The results obtained by the mission established (i) A tenuous but active hydrosphere (ii) Volcanically active and geologically dynamic Moon and (iii) Global melting of Moon’s surface r...

Goldschmidt crater and the Moon’s north polar region: Results from the Moon Mineralogy Mapper (M)

[1] Soils within the impact crater Goldschmidt have been identified as spectrally distinct from the local highland material. High spatial and spectral resolution data from the Moon Mineralogy Mapper (M) on the Chandrayaan‐1 orbiter are used to examine the character of Goldschmidt crater in detail. Spectral parameters applied to a north polar mosaic of M data are used to discern large‐scale comp...

Lunar H 2 O / Oh - Distributions : Revised Infrared Spectra from Improved Thermal Corrections

Introduction: There has been considerable interest in the spectral response of the lunar surface near 2.8 and 2.95 μm, where OHand H2O have strong absorptions. Previous studies have identified these absorptions with variable strengths across the lunar surface [1–7]. In particular, the absorptions have been found to be most prominent at higher latitudes and at early and late local times (e.g., [...

Non-linear Spectral Un-mixing Using Hapke Modeling: Application to Remotely Acquired M3 Spectra of Spinel Bearing Lithologies on the Moon

Introduction: Rocks and soils are mostly an intimate mixture of component minerals. Photons of light falling onto such a target are multiply scattered and in the process interact with more than one type of mineral. The reflected photons received at the detector therefore carry information from multiple components present in the mixture, with individual components contributing to the reflected p...
