Lunarcrete, also known as "mooncrete", an idea first proposed by Larry A. Beyer of the University of Pittsburgh in 1985, is a hypothetical construction aggregate, similar to concrete, formed from lunar regolith, that would reduce the construction costs of building on the Moon. [3] AstroCrete is a more general concept also applicable for Mars.
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]
An artificially colored mosaic constructed from a series of 53 images taken through three spectral filters by Galileo's imaging system as the spacecraft flew over the northern regions of the Moon on 7 December 1992. The colors indicate different materials. A lunar anorthosite rock collected by the Apollo 16 crew from near the crater Descartes
On 16 December 2020, China's Chang'e 5 mission returned to Earth with about 2 kilograms of rock and dirt it picked up from the Moon. It is the first lunar regolith sample to return to Earth since 1976.
Moon rocks on Earth come from four sources: those collected by six United States Apollo program crewed lunar landings from 1969 to 1972; those collected by three Soviet uncrewed Luna probes in the 1970s; those collected by the Chinese Lunar Exploration Program's uncrewed probes; and rocks that were ejected naturally from the lunar surface before falling to Earth as lunar meteorites.
The Genesis Rock (sample 15415) is a sample of Moon rock retrieved by Apollo 15 astronauts James Irwin and David Scott in 1971 during the second lunar EVA, at Spur crater on Earth's Moon. With a mass of c. 270 grams (4,200 grains), [ 1 ] it is currently stored at the Lunar Sample Laboratory Facility in Houston, Texas .

Big Muley is a 11.7 kg (26 lb) [3] breccia, consisting mainly of shocked anorthosite attached to a fragment of troctolitic "melt rock". The rock's cosmic ray exposure age was discovered to be about 1.8 million years, linking it to ejecta, or debris, from the impact that formed South Ray crater, to the south of the Apollo 16 landing site.
