Lunar Dayside Surface Potentials in the Terrestrial Magnetotail Inferred From Comparing Observed and Modeled Photoelectrons

open access: yesGeophysical Research Letters
As an airless body, the lunar surface is charged as a result of balancing electric currents into and away from the surface. Lunar surface charging is important for both scientific and human‐exploration purposes.

New Lunar Crater Production Function Based on High-Resolution Images

open access: yesRemote Sensing, 2023
The lunar crater production function describes the general pattern of the size–frequency distribution of craters on the lunar surface, and it is the foundation of the surface dating method via crater counting.

A proposal of lunar long duration method (Fabrication of lunar environment simulator and experimental validation)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
A lunar long duration method which utilizes a characteristic of a very low thermal conductivity of lunar regolith has been proposed. The principle of this method is to put heater in desired depth of the regolith and heat up the regolith layer during ...

Analyzing the Magnesium (Mg) Number of Olivine on the Lunar Surface and Its Geological Significance

open access: yesRemote Sensing, 2019
Olivine formation is directly related to Mg/Fe content. It is also significant in estimating the geological evolution of the moon. In this study, an estimation model of relative Mg number (Fo#) for lunar olivine was presented through multiple linear ...

Properties of Lunar Dust and Their Migration on the Moon

open access: yesSpace: Science & Technology
Lunar dust, the finest fraction of lunar regolith, has undergone important space weathering on the Moon. It not only serves as a record of the evolution of the lunar surface environment and the modification of mineral properties, but also influences the ...

Mapping of the lunar surface by average atomic number based on positron annihilation radiation from Chang’e-1

open access: yesEarth and Planetary Physics, 2018
A map of the average atomic number of lunar rock and soil can be used to differentiate lithology and soil type on the lunar surface. This paper establishes a linear relationship between the average atomic number of lunar rock or soil and the flux of ...

Pain and Patient‐Reported Physical Function Did Not Differ Among Body Composition Profiles in Patients With Hip Osteoarthritis

open access: yesArthritis Care &Research, EarlyView.
Objective To explore whether higher body fat and lower lean mass are associated with greater pain and worse patient‐reported physical function in individuals with hip osteoarthritis (OA). A secondary aim was to examine whether pain and patient‐reported physical function differ according to four body composition profiles: high body fat, low lean mass ...
