Journal ArticleDOI
Geochemistry of the lunar highlands as revealed by measurements of thermal neutrons
TL;DR: In this paper, thermal neutron emissions from the lunar surface provide a direct measure of bulk elemental composition that can be used to constrain the chemical properties of near-surface (depth 85%, are generally associated with large impact basins and are colocated with clusters of nearly pure plagioclase identified with spectral reflectance data).
Journal ArticleDOI
Analytical Identification and Characterization of the Major Geochemical Terranes of Mercury's Northern Hemisphere
Journal ArticleDOI
Detection and characterization of 0.5–8 MeV neutrons near Mercury: Evidence for a solar origin
David J. Lawrence,William C. Feldman,John O. Goldsten,Patrick N. Peplowski,D. J. Rodgers,Sean C. Solomon,Sean C. Solomon +6 more
TL;DR: The spectral shape of the measured neutence spectrum is consistent with a previously modeled fluence spectrum of neutrons that originate at the Sun and are propagated through the MESSENGER spacecraft to the NS as discussed by the authors.
Journal ArticleDOI
The MESSENGER Gamma-Ray Spectrometer: Calibration and operations
Larry G. Evans,Patrick N. Peplowski,Edgar A. Rhodes,John O. Goldsten,R. D. Starr,Sean C. Solomon,Sean C. Solomon +6 more
TL;DR: The MESSENGER spacecraft carried a suite of geochemical remote-sensing devices that included a Gamma-Ray Spectrometer (GRS) as mentioned in this paper, which was used to derive elemental composition from gamma-ray measurements.
Journal ArticleDOI
Igneous lithologies on asteroid (4) Vesta mapped using gamma-ray and neutron data
Andrew W. Beck,David J. Lawrence,Patrick N. Peplowski,C. E. Viviano-Beck,Thomas H. Prettyman,Timothy J. McCoy,Harry Y. McSween,Naoyuki Yamashita +7 more
TL;DR: In this paper, the authors use data collected by the Dawn Gamma-Ray and Neutron Detector (GRaND) at Vesta to map compositions corresponding to nearly pure igneous lithologies in the howardite, eucrite, diogenite (HED) meteorite clan (samples likely from Vesta).
