Ore Reserves - The sectors of a mineral reserve for which a company can initiate a profitable extraction operation
Consider the processes that minerals on Earth go through to be produced versus elsewhere in the solar system. On Earth, we have active geologic cycles and water can be pushed deep into the Earth, going through a supercritical process and goes through diffusion into minerals.
The Moon should be considered a prime target. We are able to reach it, there is evidence to suggest there are deposits to mine for, and it has shielded Earth from many comets and asteroids. The bodies that have collided into the Moon may have left behind deposits for us to use.
Roche Limit - Represents the minimum distance at which a smaller body can survive the gravitational attraction of the larger body in the system and remain as a distinct body held together by its own gravity.
The Roche Limit can be approximated to two planetary radii.
Retrograde motion suggests that the Moon may have been formed elsewhere and captured by the Earth’s gravitational field.
Another theory says that the Moon may have been formed when a large object struck an earlier version of Earth, causing the material that would eventually form the Moon to be expelled.
The inner Moon is lacking in iron.
The basins are the largest features on the Moon.
Prominent basins include:
Orientale Basin
Imbrium Basin
South Pole-Aitken Basin
