First remote measurements of lunar surface charging from ARTEMIS: Evidence for nonmonotonic sheath potentials above the dayside surface
[1] During an early lunar encounter, ARTEMIS‐P2 passed earthward from the Moon in the terrestrial magnetotail. Fortuitously, though more than 8000 km away, magnetic field lines connected the spacecraft to the dayside lunar surface during several time periods in both the lobe and plasma sheet. During these intervals, ARTEMIS made the first accurate and quantitative remote measurements of lunar s...
متن کاملNegative potentials above the day‐side lunar surface in the terrestrial plasma sheet: Evidence of non‐monotonic potentials
[1] The Lunar Prospector (LP) Electron Reflectometer (ER) instrument conducted a series of measurements of the lunar surface potential in a variety of conditions. Occasionally, when the Moon was exposed to the terrestrial plasma sheet and in daylight, large, unexpected negative potentials (∼−500 V) were measured. In this paper, we compare LP ER measurements with one‐dimensional particle‐ in‐cel...
متن کاملStair-step Patterns from Arrays
In array antennas, the shaped beams are produced either by amplitude control or phase control. In the present work, an attempt is made to produce them with the introduction of new aperture distribution without additional phase. Stair-step patterns are produced using Fourier transform method after introducing the proposed aperture distribution. The computed patterns are presented. These patterns...
متن کاملFeatureless spectra on the Moon as evidence of residual lunar primordial crust
We report the global distribution of areas exhibiting no absorption features (featureless or FL) on the lunar surface, based on the reflectance spectral data set obtained by the Spectral Profiler onboard Kaguya/SELENE. We found that FL sites are located in impact basins and large impact craters in the Feldspathic Highlands Terrane, while there are no FL sites in the Procellarum regions nor the ...
متن کاملThorium abundances on the lunar surface
Measurements of absolute thorium abundances on the lunar surface are presented using both the highand low-altitude data taken with the Lunar Prospector Gamma-Ray Spectrometer. An analysis of the uncertainties shows that the measured uncertainties are < 0.5 μg/g and are close to the theoretical limit of Poisson statistics. Currently, the overall systematic uncertainties are likely dominated by v...
