Gene Cernan with lunar dust stuck on his suit. Lunar dust is highly abrasive and can cause damage to human lungs, nervous, and cardiovascular systems. [19] A 2005 NASA study listed 20 risks that required further study before humans should commit to a human Mars expedition, and ranked "dust" as the number one challenge.
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 ...

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.
Astronautical hygiene evaluates, and mitigates, hazards and health risks to those working in low-gravity environments. [1] The discipline of astronautical hygiene includes such topics as the use and maintenance of life support systems, the risks of the extravehicular activity, the risks of exposure to chemicals or radiation, the characterization of hazards, human factor issues, and the ...
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 ]
Veterinarians in Palm Beach County's western communities warn horse owners of tainted feed contaminated with toxic weed.
The instrument was placed northeast of the ALSEP, 7.5 m (25 ft) away. The east sensor axis of the LEAM was aligned to a bearing of 025° to more readily capture interstellar dust particles. [1] The instrument ran for 60 hours during the lunar day and 60 hours during the lunar night with the sensor covers in place to establish a baseline.
