Remote detection of widespread indigenous water in lunar pyroclastic deposits
Milliken, Ralph E.; Li, Shuai
Laboratory analyses of lunar samples provide a direct means to identify indigenous volatiles and have been used to argue for the presence of Earth-like water content in the lunar interior. Some volatile elements, however, have been interpreted as evidence for a bulk lunar mantle that is dry. Here we demonstrate that, for a number of lunar pyroclas…
Revisiting the field geology of Taurus-Littrow
Weiss, B. P.; Robinson, M. S.; Petro, N. E. +3 more
Integration of Apollo 17 field observations and photographs, sample investigations, Lunar Reconnaissance Orbiter Camera images, Chandrayaan-1 Moon Mineralogy Mapper (M3) spectra, and Miniature Radio Frequency (Mini-RF) S-band radar images provides new insights into the geology of the valley of Taurus-Littrow on the Moon. Connecting the …
Detection of Mg-spinel bearing central peaks using M3 images: Implications for the petrogenesis of Mg-spinel
Li, Lin; Sun, Ying; Zhang, Yuanzhi
Mg-spinel bearing lithologies, lacking abundant mafic materials, have been discovered with images acquired by the Moon Mineralogy Mapper (M3) aboard Chandrayaan-1. We conducted a systematic screening of lunar crater central peaks for the presence of Mg-spinel to address its distribution and petrogenesis. 38 Mg-spinel bearing crater cent…
Upper limit of helium-4 in the sunlit lunar exosphere during magnetotail passage under low solar wind condition: Result from CHACE aboard MIP in Chandrayaan-1
Bhardwaj, Anil; Sridharan, R.; Dhanya, M. B. +3 more
The outcome of efforts to detect He-4 in the sunlit lunar exosphere as evinced by the CHACE mass spectrometer aboard the Moon Impact Probe in Chandrayaan-1 is reported. The in situ observations by CHACE were carried out in the lunar dayside, covering a broad range of lunar latitudes, when the Moon was on the verge of exiting the Earth's magnetotai…
New suprathermal proton population around the Moon: Observation by SARA on Chandrayaan-1
Barabash, Stas; Holmström, Mats; Futaana, Yoshifumi +4 more
We report a new population of suprathermal H+ (∼1.5-3 times the solar wind energy) around the Moon observed by Solar Wind Monitor (SWIM)/Sub-keV Atom Reflecting Analyzer (SARA) on Chandrayaan-1. These ions have large initial velocity (>100 km s-1) and are observed on the dayside, near the terminator, and in the near-wake r…
