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.
Lunar Sample 15016, better known as the "Seatbelt Basalt", 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 0.923 kg (2.03 lb) vesicular olivine basalt.
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.
The 842 pounds (382 kilograms) of lunar rocks and soil returned to Earth by the Apollo missions in the late 1960s and early 1970s disproved ideas that the moon was a celestial body caught in Earth ...
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 ...
The Lunar Magma Ocean (LMO) is the layer of molten rock that is theorized to have been present on the surface of the Moon. The LMO was likely present on the Moon from the time of the Moon's formation (about 4.5 or 4.4 billion years ago [ 1 ] ) to tens or hundreds of millions of years after that time.
Moon's internal structure Olivine basalt collected by Apollo 15. Thermal state of the Moon at age 100 Ma. [1]Having a mean density of 3,346.4 kg/m 3, [2] the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and planetary core.
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] Olivine and plagioclase are of about equal quantities within 76535, while the remaining approximately 4% is made up of primarily orthopyroxene.
