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 ...
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
As Troctolite 76535 is the oldest known "unshocked" (meaning unaltered by meteor impacts) lunar rock, it has been used for thermochronological calculations in order to determine whether the Moon formed a metallic core or generated a core dynamo. The results of these studies have been shown to support the core dynamo hypothesis. [7]
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]
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 ...
A priceless piece of lunar rock given to Ireland following a Nasa mission was lost in a fire at Dunsink Observatory, newly released records show.
Lunar meteorites collected in Africa and Oman are, for all practical purposes, the only source of Moon rocks available for private ownership. This is because all rocks collected during the Apollo Moon-landing program are property of the United States government or of other nations to which the U.S. conveyed them as gifts. Similarly, all lunar ...
