چکیده

Lunar Prospector gamma-ray spectrometer spectra along with counting rate maps of thorium, potassium, and iron delineate large compositional variations over the lunar surface. Thorium and potassium are highly concentrated in and around the nearside western maria and less so in the South Pole-Aitken basin. Counting rate maps of iron gamma-rays show a surface iron distribution that is in general agreement with other measurements from Clementine and the Lunar Prospector neutron detectors.

Estimation of Lunar Elemental Abundances Using Clementine UVVIS+NIR Data

Many attempts have been made to derive elemental abundances of the lunar surface from multispectral images. A method to predict Fe abundance based on Clementine UVVIS data is presented in [1]. A refined method which also addresses the TiO2 abundance is provided in [2], demonstrating that in spite of issues posed by soil maturity, grain size, mineral content, topographic shading, and glass conte...

Global spatial deconvolution of Lunar Prospector Th abundances

[1] We have completed the first global spatial deconvolution analysis of planetary gamma-ray data for lunar Th abundances as measured by the Lunar Prospector Gamma-ray Spectrometer. We tested two different spatial deconvolution techniques – Jansson’s method and the Pixon method – and determined that the Pixon method provides superior performance. The final deconvolved map results in a spatial r...

Spatial Deconvolution Studies of Nearside Lunar Prospector Thorium Abundances

Introduction: Orbital gamma-ray and neutron spectroscopy measurements have greatly contributed to our understanding of the elemental composition of the both the Moon and Mars [1,2,3,4,5]. One drawback , however, to these measurements is that the spatial resolution is quite broad since it is roughly equal to or greater than the spacecraft height above the planetary surface. For example, for the ...

Lunar Prospector: overview.

Lunar Prospector is providing a global map of the composition of the moon and analyzing the moon's gravity and magnetic fields. It has been in a polar orbit around the moon since 16 January 1998. Neutron flux data show that there is abundant H, and hence probably abundant water ice, in the lunar polar regions. Gamma-ray and neutron data reveal the distribution of Fe, Ti, and other major and tra...
