A 1 kg jar of JSC-1A lunar simulant Approximately 15 g of JSC-1A. A lunar regolith simulant is a terrestrial material synthesized in order to approximate the chemical, mechanical, engineering, mineralogical, or particle-size distribution properties of lunar regolith. [1]
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.
However, standard usage among lunar scientists is to ignore that distinction. [citation needed] "Lunar dust" generally connotes even finer materials than lunar soil, the fraction which is less than 30 micrometers in diameter. The average chemical composition of regolith might be estimated from the relative concentration of elements in lunar soil.
The box-like machine was now ingesting small quantities of a dusty regolith – a mixture of dust and sharp grit with a chemical composition mimicking real lunar soil. Soon, that regolith was gloop.
Dust mitigation. Lunar dust, also known as regolith, is a pervasive challenge on the Moon. The fine particles can be abrasive, cling to surfaces, and pose risks to equipment and human health. This ...
First Man, based on the book of the same name, tells the story of one of humanity’s greatest firsts, from the perspective of Neil Armstrong, the first human being to set foot on the Moon.
After exposure to 50 cycles of temperature changes, from -27 °C to room temperature, the simulant lunarcrete was found to be capable of withstanding compressive pressures of 17MPa, which Toutanji and Grugel believed could be raised to 20MPa if the material were reinforced with silica (also obtainable from lunar dust). [8]
Other payloads will study how lunar dust clings to various materials and will use electromagnetism to diminish or prevent abrasive regolith buildup on spacecraft, spacesuits, and habitats.
