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.
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 ...
Troctolite 76535 is a coarse-grained plutonic rock that is believed to have had a slow cooling history. The rock originates from early in the Moon's history.Geologists have described it as a coarse-grained olivine-plagioclase cumulate with a granular polygonal texture. [2]
Color: Gray, dark red-brown in transmitted light ... the place on the Moon where the rock samples were found during the 1969 Apollo 11 mission. It was the last ...
On the Moon, anorthosite is the dominant rock type of the lunar highlands which covers ~80% of the lunar surface. Lunar anorthosite is characterized as ferroan anorthosite (FAN), or magnesium anorthosite (MAN). [17]
Ferroan anorthosite (FAN) is a pristine coarse-grained igneous rock found in the lunar highlands.FANs have a Ca-rich plagioclase (called anorthite) composition greater than 90 wt%, [1] with many consisting of an anorthite-content of 99 wt%. [2]
The lunar rock, which originated from the Apollo 11 mission in 1969, was given to President Eamon de Valera by American ambassador JG Moore in 1970.
Lunar Sample 15555, better known as "Great Scott", is a lunar sample discovered and collected on the Apollo 15 mission in 1971 in the Hadley-Apennine region of the Moon. The rock is a 9.614 kg (21.20 lb) olivine -normative basalt .
