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.
Surface of asteroid 433 Eros. Regolith (/ ˈ r ɛ ɡ ə l ɪ θ /) [1] [2] is a blanket of unconsolidated, loose, heterogeneous superficial deposits covering solid rock. It includes dust, broken rocks, and other related materials and is present on Earth, the Moon, Mars, some asteroids, and other terrestrial planets and moons. [3]
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 dust is believed to be the cause of the degradation of the instruments. Apollo 17 also placed an experiment on the Moon's surface called LEAM (Lunar Ejecta and Meteorites). It looked for dust kicked up by small meteoroids hitting the Moon's surface, and recorded the speed, energy, and direction of tiny particles.
The Moon is constantly releasing atomic sodium as a fine dust from its surface due to photon-stimulated desorption, solar wind sputtering, and meteorite impacts. [4] Solar radiation pressure accelerates the sodium atoms away from the Sun, forming an elongated tail toward the antisolar direction.
A wheeled rover that was released before the SLIM craft landed snapped a photo that appears to show the probe upside-down on the moon’s surface. As such, the lander’s solar panels are not ...
On the Moon, the spectral effects of space weathering are threefold: as the lunar surface matures it becomes darker (the albedo is reduced), redder (reflectance increases with increasing wavelength), and the depth of its diagnostic absorption bands are reduced [4] These effects are largely due to the presence of nanophase iron in both the agglutinates and in the accreted rims on individual grains.
What they found was material high in carbon, nearly 5% by weight of an element that is the foundation of life on Earth, as well as water molecules crystallized in clay fibers, Lauretta said.
