Moon Rock taking to during the six Apollo missions, rocks were collected from the moon. The purpose of collecting the rocks was to learn about the origin of the moon, its history and its environment .
From 1969 to 1972, the astronauts collected about 380 kg and 2415 pieces of rock.
Moon rock types
Moon rocks types usually in the month ranged from grayish black to white to green. Some rocks were glassy, some hard, some fragile.As a result of the analyzes, 3 different rock types were found; basaltic rock type, volcanic ash and breccia form. Pristine rock is rock that has not been hit by meteorites. Pristine rock is commonly composed of calcium-rich plagioclase feldspar and is gray in color.
Moon rock composition
Moon rocks composition are unique in two ways compared to those around the world. The first one is not oxidized because there is no water.The second is; pockmarks formed as a result of small meteor crashes. Since there is no atmosphere in the moon, small meteorites form Zap pits.
Moon rock classification
Scientists use the same categories for classifying lunar rocks as they use for igneous rocks on Earth. Based on mineral composition, scientists named a new class of moon rocks called KREEP rocks. These contain high amounts of potassium (K), rare Earth elements (REE), and phosphorus (P). These rocks are more radioactive and higher in thorium than Earth rocks.
Moon rock research
Moon rock research continues at the Johnson Space Center in Houston, Texas. The rocks are protected in stainless steel vaults in a dry nitrogen atmosphere to keep them moisture- and rust-free. Scientists continue to pose questions about these rocks as they study the Moon’s origin and history.
