Radiation Sintering of Lunar Dust

Science, 1965
Protons in the solar wind displace atoms in the grains of lunar dust. These atoms may, through diffusion, sinter the dust layer into a partly coherent but still highly porous structure.

Lunar and Martian Dust Dynamics

IEEE Industry Applications Magazine, 2010
In order to support human and robotic explorations of Mars and beyond,the National Aeronautics and Space Administration (NASA) has undertaken lunar missions. One technological problem is the mitigation of dust hazards associated with both lunar and Mars missions.

An electrostatic lofting model based on adhesion separation characteristics for lunar dust

, 2020
Since the moon landings of the 1970’s, researchers have believed that “horizon glow”(HG) observed on the moon are formed by the scattering of sunlight by the electrostatic lofted dust.

On Rocket Plume, Lunar Crater and Lunar Dust Interactions

48th AIAA Aerospace Sciences Meeting Including the New Horizons Forum and Aerospace Exposition, 2010
This paper presents our recent progress on the investigations of rocket Plume-Crate interaction and Lunar/Martian Dust Interaction (PDI). PDI is a very challenging problem of complex flow/soil interactions, involved with multi-physics, multi-scales, multi-dimensions, and multi-species. We are developing hybrid computational fluid dynamics (CFD) package,

Dust emission evaluation of the flexible metal wheel over lunar terrain and fender effect

Mechanics based design of structures and machines
The lunar rover’s wheels produce substantial dust emission during movement, presenting safety concerns for astronauts and potential equipment wear. Replicating the dust emission behavior in the low-gravity environment on Earth is challenging.

Gas-particle two-way coupled method for simulating the interaction between a rocket plume and lunar dust

Acta Astronautica, 2019
During the landing process of lunar landers, the lunar surface is eroded by the exhaust plume and a large amount of lunar dust entrained into a high-velocity spray.

The Lunar Dust Experiment (LDEX) Onboard the Lunar Atmosphere and Dust Environment Explorer (LADEE) Mission

Space Science Reviews, 2014
The Lunar Dust Experiment (LDEX) is an in situ dust detector onboard the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission. It is designed to characterize the variability of the dust in the lunar exosphere by mapping the size and spatial distributions of dust grains in the lunar environment as a function of local time and the position of ...

Lunar Dust and the Gegenschein

Nature, 1961
OF the four possible explanations of the gegenschein which have been proposed, not one so far has explained satisfactorily the meagre observational data concerning this phenomenon. The Glyden–Moulton hypothesis1, which suggests a concentration of meteoric material at a libration point of the Sun–Earth system, seems incapable of explaining all the ...

Lunar dust and dusty plasmas: Recent developments, advances, and unsolved problems

Planetary and Space Science, 2018
A renaissance is being observed currently in investigations of the Moon. The Luna-25 and Luna-27 missions are being prepared in Russia. At the same time, in connection with the future lunar missions, theory investigations of dust and dusty plasmas at the
