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 composition of the lunar core is not well constrained, but most believe that it is composed of metallic iron alloy with a small amount of sulfur and nickel. Analyses of the Moon's time-variable rotations indicate that the core is at least partly molten. [6]
The Moon is Earth's only natural satellite.It orbits around Earth at an average distance of 384,400 km (238,900 mi), about 30 times the width of Earth. The Moon faces Earth always with the same side, because tidal forces between Earth and the Moon have synchronized the Moon's rotation period with its orbital period (lunar month) at 29.5 Earth days.
[137] [138] The last attempt to define acceptable detailed rules for exploitation, ended in June 2018, after S. Neil Hosenball, who was the NASA General Counsel and chief US negotiator for the Moon Treaty, decided that negotiation of the mining rules in the Moon Treaty should be delayed until the feasibility of exploitation of lunar resources ...
Luna 25, also called the Luna-Glob-Lander, will study the composition of the moon’s polar soil and the plasma and dust contained in the very thin lunar exosphere, or the moon’s scant ...
The composition of Lunar regolith reflects the composition of the parent rocks it overlies. Over time, material is mixed both vertically and horizontally (a process known as "gardening") by impact processes. While mare and highland regolith have distinct compositions, their mineral inventories are very similar, rather expressing a difference of ...

The Moon formed after a collision 4.5 billion years ago between the young Earth and a Mars-sized object, called Theia - but what happened next? Mystery of how moon formed could be solved at last ...
