In most of the lunar regolith, half of the particles are made of mineral fragments fused by the glassy particles; these objects are called agglutinates.

Knowledge of the processes that create and modify the lunar regolith is essential to understanding the compositional and structural attributes of other airless planet and asteroid regoliths.
23.
Finally, the lunar regolith is very compact below its surface dust layer, making it impossible for the descent engine to blast out a " crater ".
24.
One of these booms carried a penetrometer, designed to measure the forces required to penetrate the lunar regolith the penetrating force being supplied by a minute explosive charge.
25.
The physical and optical properties of lunar regolith are altered through a process known as space weathering, which darkens the regolith over time, causing crater rays to fade and disappear.
26.
On January 31, 2013, the ESA working with an independent architectural firm, tested a 3D-printed structure that could be constructed of lunar regolith for use as a Moon base.
27.
Such experiments might include atmospheric and dust instruments, plasma physics investigations, astronomical instruments, electromagnetic profiling of lunar regolith and crust, local geochemistry, and in-situ resource utilization demonstrations.
28.
The term lunar soil is often used interchangeably with " lunar regolith " but typically refers to the finer fraction of regolith, that which is composed of grains one centimetre in diameter or less.
29.
:Over eons, the top several meters of the lunar regolith are stirred up via the action of micrometeorites, through a process known as lunar gardening ( wow, a red link ).
30.
Heather shows them a radiation shielding sublevel of the station on the outer edge of its rotating ring; it is filled with dirt made from lunar regolith tailings from the station's construction.
