Thermal state of the Moon at age 100 Ma. [1] Having a mean density of 3,346.4 kg/m 3, [2] the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and planetary core. This structure is believed to have resulted from the fractional crystallization of a magma ocean shortly after its formation about 4.5 billion ...
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.
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 ...

A lunar dome is a type of shield volcano that is found on the surface of the Earth's Moon. They are typically formed by highly viscous, possibly silica-rich lava, erupting from localized vents followed by relatively slow cooling. Lunar domes are wide, rounded, circular features with a gentle slope rising in elevation a few hundred meters to the ...
They usually begin at an extinct volcano, then meander and sometimes split as they are followed across the surface. As of 2013, 195 sinuous rilles have been identified on the Moon. [2] Vallis Schröteri in Oceanus Procellarum is the largest sinuous rille, and Rima Hadley is the only one visited by humans, on the Apollo 15 mission.
The temperature 1 meter below the surface of the Moon is estimated to be near constant over the period of a month varying with latitude from near 220 K (−53 °C) at the equator to near 150 K (−123 °C) at the poles. [12] This could be used as a heat reservoir. The Moon is highly depleted in volatile elements, such as nitrogen and hydrogen ...
