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]
Platinum exists in higher abundances on the Moon and in meteorites. Correspondingly, platinum is found in slightly higher abundances at sites of bolide impact on Earth that are associated with resulting post-impact volcanism, and can be mined economically; the Sudbury Basin is one such example.

Humans have left over 187,400 kilograms (413,100 lb) of material on the Moon. Besides the 2019 Chang'e 4 and SLIM missions, the only artificial objects on the Moon that are still in use are the retroreflectors for the Lunar Laser Ranging experiments left there by the Apollo 11 , 14, and 15 astronauts, Chandrayaan-3 lunar lander, and by the ...
Volcanic eruptions were happening as recently as 120 million years ago, study suggests
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 ...
NASA astronauts who visited the Moon during the Apollo 14 mission hauled back a whole bunch of material from its surface. At the time, they believed they were bringing Moon rocks and dust so that ...
Add in high levels of platinum found from Syria to South Carolina—rare in Earth’s soil, but incredibly common in comets—and the location of both magnetic balls of iron known as ...
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.
