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 ...
Lunar nearside with major maria and craters labeled. Lunar maria (singular mare) are large, dark, regions of the Moon.They do not contain any water, but are believed to have been formed from molten rock from the Moon's mantle coming out onto the surface of the Moon.
Topography of the Moon. STL 3D model of the Moon with 10× elevation exaggeration rendered with data from the Lunar Orbiter Laser Altimeter of the Lunar Reconnaissance Orbiter. Selenography is the study of the surface and physical features of the Moon (also known as geography of the Moon, or selenodesy). [1]
Two contrasting lightnesses of the lunar disc at crescent phase, overexposed to show earthshine.Across the Moon, the lunar terminator is visible, the borderline between the Moon's day and night; the lunar limb is the Moon's profile against the dark sky, top right in this picture.
The following outline is provided as an overview of and topical guide to the Moon: . Moon – Earth's only permanent natural satellite.It is one of the largest natural satellites in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary).
Luna developed an "emergency situation" that occurred during the reduction of the probe to a pre-landing orbit. The lunar lander abruptly lost communication at 2:57 p.m. (11:57 GMT). Luna 25 was a lander only, with a primary mission of proving the landing technology.
The Soviet Union continued sending robotic missions to the Moon until 1976, deploying in 1970 with Luna 17 the first remote controlled rover Lunokhod 1 on an extraterrestrial surface, and collecting and returning 0.3 kg of rock and soil samples with three Luna sample return missions (Luna 16 in 1970, Luna 20 in 1972, and Luna 24 in 1976).

This list is not comprehensive, as surveying of the Moon is a work in progress. Heights are in meters; most peaks have not been surveyed with the precision of a single meter.
