Lunar Regolith at Tranquillity Base
Science, 1970The regolith at Tranquillity Base is a layer of fragmental debris that ranges in thickness from about 3 to 6 meters. The thickness of the regolith and the exposure histories of its constituent fragments can be related, by means of a relatively simple model, to the observed crater distribution.

Lunar Regolith Particles In Outposts [PDF]
The US, India, China, Japan, and Europe plan for future crewed lunar missions. While mission architecture may be superficially similar to the American Apollo program of the 1960s and 1970s, future missions will vary considerably from that precedent in duration and complexity.

Evaluations of lunar regolith simulants
Planetary and Space Science, 2016Apollo lunar regolith samples are not available in quantity for engineering studies with In-Situ Resource Utilization (ISRU). Therefore, with expectation of a return to the Moon, dozens of regolith (soil) simulants have been developed, to some extent a result of inefficient distribution of NASA-sanctioned simulants.

The porosity of the upper lunar regolith
Icarus, 2016Abstract The porosity of the upper centimeter or so of the lunar regolith strongly affects several properties that are commonly studied remotely. Hence, it is important to determine its value. We have reanalyzed the data of Ohtake et al. (Ohtake et al. [2010]. Space Sci.

A Global Thermal Conductivity Model for Lunar Regolith at Low Temperatures
Journal of Geophysical Research: Planets, 2021Although some of the coldest surface temperatures in the entire Solar System are found near the poles of our own Moon, the thermophysical properties of lunar regolith at these ultracold temperatures (i.e., below ∼150 K) are not well understood.

Abstract The lunar regolith consists of the fragmental unconsolidated mantle which overlies more consolidated or crystalline rocks at the surface of the moon. The thickness of the regolith ranges from a few meters in some areas overlying mare basalt flows to tens of meters over much of the highland terrain.

The extent of lunar regolith mixing
Earth and Planetary Science Letters, 1979The activity of solar cosmic-ray-produced Mn-53 measured as a function of depth in the upper 100 g/sq cm of lunar cores 60009-60010 and 12025-12028 is discussed. Analyses of samples from the Apollo 15 and 16 drill stems together with authors' previously published results (1974, 1976), and the Battelle Na-22 and Al-26 data, indicate that in three of the

Re-Evaluating Influence of Rocks on Microwave Thermal Emission of Lunar Regolith Using CE-2 MRM Data
IEEE Transactions on Geoscience and Remote Sensing, 2021The influence of rocks on the microwave thermal emission (MTE) of the lunar regolith has not been fully studied with the four-channel microwave radiometer (MRM) data onboard Chang'e-1/2 satellites.

Water Formation in the Lunar Regolith
Cosmic Research, 2019This study shows that oxygen atoms can be released from a crystal lattice of silicon dioxide in the lunar regolith as parts of silver hydroxide molecules. In turn, silver hydroxide can relatively easily react with hydrogen to generate water and silver. This means that the formation of water molecules involved in near-surface lunar soil is possible. The

The chemistry of carbon in the lunar regolith
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1977The current status of knowledge concerning the chemistry of carbon in the lunar regolith is discussed. The respective roles of the solar wind and micrometeorite impact in contributing carbon and providing energy to stimulate chemical reactions and mobilize carbon phases are examined.
