Lunar regolith is the unconsolidated material found on the surface of the Moon and in the Moon's tenuous atmosphere. Sometimes referred to as Lunar soil, Lunar soil specifically refers to the component of regolith smaller than 1 cm. It differs substantially in properties from terrestrial soil.

2025年2月12日 · Lunar regolith covers virtually the entire surface of the Moon. Without blowing winds and flowing rivers to gently erode the lunar regolith, the dust particles maintain sharp, razor-like edges. This is also why until another impact erases them, one can still see the Apollo astronauts' boot prints on the lunar surface.

2019年4月5日 · Lunar regolith is made up of rock chips, mineral fragments, impact and volcanic glasses and a peculiar component only found on the Moon called “agglutinates” (Figure 1). The ratio of these various components varies widely from one soil to the next (Figure 2). Figure 1. Photograph of a large size fraction of a lunar soil showing the various ...

4 天之前 · As noted above, the lunar regolith comprises rock fragments in a continuous distribution of particle sizes. It includes a fine fraction—dirtlike in character—that, for convenience, is called soil. The term, however, does not imply a biological contribution to …

2025年3月5日 · Abstract. The first in-situ measurements of thermal properties of lunar regolith at a high latitude location (69.36 S, 32.34 E) in the south polar region were made by the Chandra’s Surface Thermophysical Experiment (ChaSTE) probe aboard India’s Chandrayaan-3 Lander during 24 August to 01 September 2023. The probe with 10 closely spaced temperature …

Discover how Apollo astronauts collected lunar regolith using specialized tools, innovative techniques, and meticulous preservation methods.

2025年3月4日 · The thermal conductivity of the lunar regolith is an essential parameter in studying the thermal behavior of the Moon and in planning future lunar exploration. The Chandra’s Surface ...

Lunar regolith simulants are terrestrial materials engineered to replicate the unique properties of Lunar soil. These simulants play a crucial role in the advancement of space exploration, providing researchers with the means to study and develop technologies necessary …

Apollo lunar module landings shows the upper layers of regolith being scoured away by the descent engine’s exhaust plume, but the lack of any measurable crater formation under the engines indicates how deeper levels of regolith have increasing shear strength to …

2019年10月15日 · Here we present the first study to obtain major element, trace element, and Ar isotopic data for impact glasses from the Apollo 16 regolith sample 66031. Thirty particles were analysed with 27 of them yielding useable age information.
