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 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. This list also includes the one oceanus and the features known by the names lacus, palus and sinus.
The Moon has been divided into 30 quadrangles by the United States Geological Survey at the 1:2,500,000 map scale. [1] At the 1:1,000,000 scale it's divided into 144 quadrangles. [2] The quadrangles are numbered in bands from north to south. Each band is then divided into a latitude-dependent number of quadrangles.
The Moon is Earth's only natural satellite.It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
Selenography – study of the surface and physical features of the Moon. Historically, the principal concern of selenographists was the mapping and naming of the lunar maria, craters, mountain ranges, and other various features.
In order to be considered a "mini-moon," an incoming object must reach Earth at a range around 2.8 million miles and at a steady space of about 2,200 mph, according to Marcos.
Moon landing deniers say there's clear photographic evidence of this, and point out that because there's no breeze on the moon, this must be fake. Apollo 11astronaut Edwin Buzz Aldrin, on the Moon ...
Scientists have discovered carbon dioxide and hydrogen peroxide on the surface of Charon, Pluto's largest moon, offering clues about the origins of the space rock and other celestial objects in ...
