Numerical investigations of the micro lunar dust particles deposition in the human oral respiratory airway.

Journal of Hazardous Materials, 2023
Understanding the deposition of lunar dust (LD) particles in the human respiratory system is of great significance for protecting astronauts' health from the toxicity of lunar dust.

Numerical analysis of micro lunar dust deposition in the human nasal airway.

Journal of Hazardous Materials, 2023
The toxicity of Lunar dust (LD) is well-known to harm astronauts' health. However, the characteristics of micro-LD deposition in the human nasal airway remains unknown, and studying it through experiments is challenging.

Lunar dust: A unique nasal irritant forgotten by history

International Forum of Allergy and Rhinology, 2023
In the early morning hours of December 14, 1972, Apollo 17 astronaut Harrison “Jack” Schmitt took one final look at the Valley of Taurus-Littrow. As Schmitt climbed aboard the Lunar Excursion Module (LEM), he and Eugene Cernan removed their spacesuits ...

Lunar Dust-Mitigation Behavior of Aluminum Surfaces with Multiscale Roughness Prepared by a Composite Etching Method.

ACS Applied Materials and Interfaces, 2022
Reducing lunar dust adhesion to various material surfaces is important for protecting equipment from damage during lunar exploration missions. In this study, we investigate the lunar dust-mitigation ability and dust adhesion force of aluminum (Al ...

Review of research on lunar dust dynamics

Astrophysics and Space Science, 2022
Lunar dust particles are generated by hypervelocity impacts of interplanetary micrometer meteoroids onto the surface of the Moon, which seriously threatens the security of explorations.

Electromagnetic Characterization of Lunar Dust Simulants

2022 16th European Conference on Antennas and Propagation (EuCAP), 2022
Even though the colonization of the Moon is still a long term objective for mankind, there already exist studies analysing the different usages lunar dust (regolith) might have. Following this idea, several simulants of the real regolith have been developed in order to understand its behaviour and be able to work with it in a more efficient way.

The lunar dust environment

Planetary and Space Science, 2011
Abstract Each year the Moon is bombarded by about 10 6  kg of interplanetary micrometeoroids of cometary and asteroidal origin. Most of these projectiles range from 10 nm to about 1 mm in size and impact the Moon at 10–72 km/s speed. They excavate lunar soil about 1000 times their own mass.

Lunar Dust Levitation

Journal of Aerospace Engineering, 2009
Observations of a lunar "horizon glow" by several Surveyor spacecraft on the lunar surface in the 1960s and detections of dust particle impacts by the Apollo 17 Lunar Ejecta and Meteoroid Experiment have been explained as the result of micron-sized charged particles lifting off the surface. The surface of the Moon is exposed to the solar wind and solar
