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.

The scientific case for renewed human activities on the Moon [PDF]

open access: yes, 2004
It is over 30 years since the last human being stood on the lunar surface and this long hiatus in human exploration has been to the detriment of lunar and planetary science. The primary scientific importance of the Moon lies in the record it preserves of

On the survivability and detectability of terrestrial meteorites on the moon [PDF]

open access: yes, 2008
Materials blasted into space from the surface of early Earth may preserve a unique record of our planet's early surface environment. Armstrong et al. (2002) pointed out that such materials, in the form of terrestrial meteorites, may exist on the Moon and

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 ...

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 ...

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 ...

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 ...

Lunar meteorite regolith breccias: an in situ study of impact melt composition using LA-ICP-MS with implications for the composition of the lunar crust

open access: yes, 2010
Dar al Gani (DaG) 400, Meteorite Hills (MET) 01210, Pecora Escarpment (PCA) 02007, and MacAlpine Hills (MAC) 88104/88105 are lunar regolith breccia meteorites that provide sampling of the lunar surface from regions of the Moon that were not visited by ...

A 3D hybrid simulation study of the electromagnetic field distributions in the lunar wake

open access: yes, 2011
As a consequence of its lack of a thick atmosphere and an ionosphere, the interaction of the solar wind with the Moon is characterized by the direct impact of the solar wind on its sunward hemisphere.
