The Genesis Rock (Lunar sample 15415), obtained from the Moon by astronauts during Apollo 15 mission, has been dated at 4.08 billion years. [18] During Apollo 16, older rocks, including Lunar sample 67215, dated at 4.46 billion years, were brought back. [19] Some types of meteorite are older than the Earth, having formed in the early Solar ...
They range in age from about 3.16 billion years old for the basaltic samples derived from the lunar maria, up to about 4.44 billion years old for rocks derived from the highlands. [22] Based on the age-dating technique of "crater counting," the youngest basaltic eruptions are believed to have occurred about 1.2 billion years ago, [ 23 ] but ...
Lunar Sample 14321, better known as "Big Bertha", is a lunar sample containing an embedded Earth-origin meteorite collected on the 1971 Apollo 14 mission. It was found in the Fra Mauro region of the Moon. Big Bertha is the first discovered meteorite from Earth, and the embedded meteorite portion is the oldest known Earth rock.
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 oldest Moon rocks are up to 4.5 billion years old, [37] making them 200 million years older than the oldest Earth rocks, which are from the Hadean eon and dated 3.8 to 4.3 billion years ago. The rocks returned by Apollo are very close in composition to the samples returned by the independent Soviet Luna programme .
The moon may be older than some scientists thought, according to a new study. It suggests that rock samples from the Apollo missions date back to a melting event, not to the moon's formation.
The Genesis Rock (sample 15415) is a sample of Moon rock retrieved by Apollo 15 astronauts James Irwin and David Scott in 1971 during the second lunar EVA, at Spur crater on Earth's Moon. With a mass of c. 270 grams (4,200 grains), [ 1 ] it is currently stored at the Lunar Sample Laboratory Facility in Houston, Texas .
The world’s oldest dated rune stone, a landmark discovery revealed in 2023, is just one piece of a larger, nearly 2,000-year-old slab, new research has found. Now, scientists in Norway are ...
