Geological studies of the Moon are based on a combination of Earth-based telescope observations, measurements from orbiting spacecraft, lunar samples, and geophysical data.
Earth’s Moon is thought to have formed in a tremendous collision. A massive object ― named Theia after the mythological Greek Titan who was the mother of Selene, goddess of the Moon ― smashed into Earth, flinging material into space that became the Moon. NASA. The early solar system would have been a chaotic, terrifying place.
1 gru 2012 · The Moon was understood as an inert body with its geology mainly restricted to impact and volcanism with associated tectonics, and a relative simple composition. Unlike Earth, an absence of plate tectonics has preserved a well-defined accretion and geological evolution record.
11 paź 2023 · Moon 101: Surface Geology and Morphology of the Moon. In this episode, Julie Stopar helps us understand the makeup of the Moon and how it will drive exploration goals and needs.
At the Moon’s center is a dense, metallic core. This core is largely composed of iron and some nickel. The Moon’s core is relatively small (about 20% of its diameter) compared to other terrestrial worlds (like Earth) with cores measuring closer to 50% of their diameters.
More than two decades of study have established the major features of lunar geologic style and history. The most numerous and significant landforms belong to a size-morphology series of simple craters, complex craters, and ringed basins that were formed by impacts.
20 kwi 2020 · The lunar map, called the “Unified Geologic Map of the Moon,” will serve as the definitive blueprint of the moon’s surface geology for future human missions and will be invaluable for the international scientific community, educators and the public-at-large.
