Geological studies of the Moon are based on a combination of Earth-based telescope observations, measurements from orbiting spacecraft, lunar samples, and geophysical data. . Six locations were sampled directly during the crewed Apollo program landings from 1969 to 1972, which returned 382 kilograms (842 lb) of lunar rock and lunar soil to Earth [8] In addition, three robotic Soviet Luna ...
Moonmilk (sometimes called mondmilch, also known as montmilch or cave milk) is a white, creamy substance found inside limestone, dolomite, and possibly other types of caves. It is a precipitate from limestone comprising aggregates of fine crystals of varying composition, usually made of carbonates such as calcite , aragonite , hydromagnesite ...
Hematite, a mineral composed of ferric oxide (Fe 2 O 3), has been found on the Moon. This mineral is a product of a reaction between iron, oxygen, and liquid water. Oxygen from the Earth's atmosphere may cause this reaction as indicated by there being more hematite on the side of the Moon facing the Earth. [46]
Basalt (UK: / ˈ b æ s ɒ l t,-ɔː l t,-əl t /; [1] [2] US: / b ə ˈ s ɔː l t, ˈ b eɪ s ɔː l t /) [3] is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon.
The ages of the mare basalts have been determined both by direct radiometric dating and by the technique of crater counting.The radiometric ages range from about 3.16 to 4.2 billion years old (Ga), [4] whereas the youngest ages determined from crater counting are about 1.2 Ga. [5] Updated measurements of samples collected by the Chang’e-5 mission show that some lunar basalts could be as ...
Kamo'oalewa has an odd near-Earth orbit that perplexed scientists, especially given that its composition is not like other near-Earth satellites.
The celestial near-Earth object, known as 2024 PT5, measures about 33 feet (10 meters) wide; however, it’s not in any danger of colliding with Earth now or over the next few decades due to its ...
Olivine basalt collected from the rim of Hadley Rille by the crew of Apollo 15. Moon rock or lunar rock is rock originating from Earth's Moon.This includes lunar material collected during the course of human exploration of the Moon, and rock that has been ejected naturally from the Moon's surface and landed on Earth as meteorites.
