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.

Contaminants in the Lunar Regolith
Астрономический вестник, 2023The lunar regolith delivered to Earth in the 1970s by the Soviet automatic stations Luna-16, -20, and -24, despite the small amount of material, is of great value for science and requires careful study. How ever, since soil samples have gone quite a long way from the moment of extraction to direct examination, there is a danger of possible ...

In the year 2004 NASA declared its mission to prepare for a return of man to the moon as early as 2015 but no later than 2020, while continuing with robotic missions to Mars (NASA 2004). As a long-term goal, it was intended to establish permanent human presence on the moon and eventually send human missions to Mars.

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.

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.

Lunar Regolith Particles In Outposts
AIAA SPACE 2009 Conference & Exposition, 2009The 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.

Oxygen Separation from Lunar Regolith
SAE Technical Paper Series, 2007<div class="htmlview paragraph">A novel method for separating oxygen from lunar regolith has recently been granted two US patents. Early research at the system level has demonstrated the viability of this concept for silicon extraction. The focus of this paper is the process thermodynamics and energy scale-up for oxygen extraction.
