The apparent toxic effects of lunar dust were never comprehensively studied after the program, and the concentrations of dust that contaminated the spacecraft are not known. In each case, symptoms resolved within 24 hours, and post-flight pulmonary testing found no permanent impacts in the astronauts.
Lunar dust or regolith is the layer of particles on the Moon's surface and is approximately <100 um. [21] The grain shapes tend to be elongated. Inhalation exposure to this dust can cause breathing difficulties because the dust is toxic. It can also cloud astronauts' visors when working on the Moon's surface.
Moon dust is an extremely abrasive glassy substance formed by micrometeorites and unrounded due to the lack of weathering. It sticks to everything, can damage equipment, and it may be toxic. Since it is bombarded by charged particles in the solar wind, it is highly ionized, and is extremely harmful when breathed in.
NASA Researchers view a demonstration of the moon dust simulator in the 8- by 6-Foot Supersonic Wind Tunnel facility at the NASA Lewis Research Center (1960).. In the run-up to the Apollo program, crushed terrestrial rocks were first used to simulate the anticipated soils that astronauts would encounter on the lunar surface. [2]
The term lunar soil is often used interchangeably with "lunar regolith" but typically refers to the finer fraction of regolith, that which is composed of grains one centimetre in diameter or less. Some have argued that the term "soil" is not correct in reference to the Moon because soil is defined as having organic content, whereas the Moon has ...
A new study published on Wednesday suggested that a deep-space umbrella of lunar dust could help slow the effects of climate change. The study, published in the PLoS science journal, explains how ...

Lunar horizon glow is a phenomenon in which dust particles in the Moon's thin atmosphere create a glow during lunar sunset. The Surveyor program provided the first data and photos of the phenomenon. Astronauts in lunar orbit observed it during the Apollo 15 and Apollo 17 missions. Lunar horizon glow as observed by Surveyor 7 mission.
