Journal ArticleDOI
Magnesian anorthosites and a deep crustal rock from the farside crust of the moon
Hiroshi Takeda,Akira Yamaguchi,Donald D. Bogard,Yuzuru Karouji,Mitsuru Ebihara,Makiko Ohtake,Kazuto Saiki,Tomoko Arai +7 more
TL;DR: Among over thirty lunar meteorites recovered from the hot deserts and Antarctica, Dhofar 489 is the most depleted in thorium, FeO, and rare earth elements (REE) as discussed by the authors.
Journal ArticleDOI

TL;DR: In this paper, an empirical analysis of spectral reflectance data from the Kaguya lunar orbiter indicates a systematic difference in the degree of differentiation in the oldest lunar crustal terrains, linking the lunar dichotomy to crystallization of the magma ocean.
Journal ArticleDOI

TL;DR: In 2010, the PMSCF/JAXA was established in Sagamihara, Kanagawa, Japan, to curate planetary material samples returned from space in conditions of minimum terrestrial contaminants as discussed by the authors.
Journal ArticleDOI

TL;DR: In this article, the Kaguya Gamma-Ray Spectrometer (GRS) was used to identify uranium gamma-ray lines from the Moon with a superior energy resolution of ∼1%.
Journal ArticleDOI
X-ray absorption near edge structure spectroscopic study of Hayabusa category 3 carbonaceous particles

TL;DR: In this paper, an analysis with a scanning transmission x-ray microscope (STXM) using X-ray absorption near edge structure (XANES) spectroscopy was applied for the molecular characterization of two kinds of carbonaceous particles of unknown origin, termed category 3, which were collected from the Hayabusa spacecraft sample catcher.
