Detection of the Lunar Surface Soil Permittivity with Megahertz Electromagnetic Wave [PDF]
Sensors, 2021 In this paper, the detection of the lunar surface soil permittivity with megahertz electromagnetic (EM) waves by spaceborne radar is studied based on the EM scattering theory, the Boltzmann–Shukla equations, and the improved scattering matrix method ...

Petrologic Characteristics of the Lunar Surface. [PDF]
Sci Rep, 2015 AbstractPetrologic analysis of the lunar surface is critical for determining lunar formation and evolution. Here, we report the first global petrologic map that includes the five most important lunar lithological units: the Ferroan Anorthositic (FAN) Unit, the Magnesian Suite (MS) Unit, the Alkali Suite (AS) Unit, the KREEP Basalt (KB) Unit and the ...

Recent progress in lunar dust migration and biological toxicity research
地球与行星物理论评, 2021 Lunar dust is easy to transport both vertically and horizontally, which affects the lunar surface material distribution, and the dusty plasma environment near the lunar surface.

Minimagnetospheres above the Lunar Surface and the Formation of Lunar Swirls [PDF]
Physical Review Letters, 2012 In this paper we present in-situ satellite data, theory and laboratory validation that show how small scale collisionless shocks and mini-magnetospheres can form on the electron inertial scale length. The resulting retardation and deflection of the solar wind ions could be responsible for the unusual "lunar swirl" patterns seen on the surface of the ...

Nature, 1960 MR. FIRSOFF'S clarification of ‘lunavoes’ is very helpful, and I must apologize for having confused his explanation of rays with Spurr's explanation of radial gullies. My argument against the presence of water applies equally to ice and snow, which would be dissociated by solar ultra-violet radiation in the vapour phase.

Global Hall MHD Simulations of the Solar Wind Implantation Flux on the Lunar Surface
The Planetary Science Journal, 2023 The solar wind can directly interact with the lunar surface and provide an important source for surface space weathering and water generation. Here we study the solar wind implantation flux on the lunar surface with global Hall MHD simulations.

Color Differences on the Lunar Surface [PDF]
, 1968 Both a detailed literature survey and a new observational study were performed to determine and extend the knowledge of spectral reflectivity differences (color differences) on the lunar surface in the extended visible wavelength region.

Reachable set analysis of practical trans-lunar orbit via a retrograde semi-analytic model
Earth, Planets and Space, 2023 Different from the Apollo flight mode, a safer trans-lunar flight mode for the crews is preferred. The previous-arrived lunar module rendezvouses with the crew exploration vehicle at a low lunar destination orbit, and then the crews ride the lunar module

The Influence of Heterogeneity on Lunar Irradiance Based on Multiscale Analysis
Remote Sensing, 2019 The Moon is a stable light source for the radiometric calibration of satellite sensors. It acts as a diffuse panel that reflects sunlight in all directions, however, the lunar surface is heterogeneous due to its topography and different mineral content ...

Photometric Lunar surface reconstruction [PDF]
2013 IEEE International Conference on Image Processing, 2013 Accurate photometric reconstruction of the Lunar surface is important in the context of upcoming NASA robotic missions to the Moon and in giving a more accurate understanding of the Lunar soil composition. This paper describes a novel approach for joint estimation of Lunar albedo, camera exposure time, and photometric parameters that utilizes an ...
