Lunar soil - Wikipedia.

Lunar soil is the fine fraction of the regolith found on the surface of the Moon.Its properties can differ significantly from those of terrestrial soil.The physical properties of lunar soil are primarily the result of mechanical disintegration of basaltic and anorthositic rock, caused by continual meteoric impacts and bombardment by solar and interstellar charged atomic particles over ....

Lunar node - Wikipedia.

A lunar node is either of the two orbital nodes of the Moon, that is, the two points at which the orbit of the Moon intersects the ecliptic.The ascending (or north) node is where the Moon moves into the northern ecliptic hemisphere, while the descending (or south) node is where the Moon enters the southern ecliptic hemisphere.. A lunar eclipse can occur only when the full Moon is ....

Lunar phase - Wikipedia.

Concerning the lunar month as viewed from Earth, the lunar phase or Moon phase is the shape of the Moon's directly sunlit portion, which can be expressed quantitatively using areas or angles or described qualitatively using the terminology of new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent..

Parallax - Wikipedia.

Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. Due to foreshortening, nearby objects show a larger parallax than farther objects when observed from different positions, so parallax can be used to determine distances..

Precession - Wikipedia.

Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself.In other words, if the axis of rotation of a body is itself rotating about a second axis, that body is said to be precessing about the second axis..

Reaction control system - Wikipedia.

A reaction control system (RCS) is a spacecraft system that uses thrusters and reaction control wheels to provide attitude control, and sometimes propulsion.Use of diverted engine thrust to provide stable attitude control of a short-or-vertical takeoff and landing aircraft below conventional winged flight speeds, such as with the Harrier "jump jet", may also be referred to ....

Shackleton (crater) - Wikipedia.

Shackleton is an impact crater that lies at the lunar south pole.The peaks along the crater's rim are exposed to almost continual sunlight, while the interior is perpetually in shadow.The low-temperature interior of this crater functions as a cold trap that may capture and freeze volatiles shed during comet impacts on the Moon. Measurements by the Lunar Prospector spacecraft ....
