Development and test of a Lunar Excavation and Size
Nov 28, 2021 · Table 1 shows that most potential end-users of excavated regolith material rely on or benefit from a certain level of size separation. Currently, excavation and size separation are usually considered as two independent steps in the ISRU process chain (see Just et al., 2020b or Hadler et al., 2020, for more details on the ISRU process chain), requiring regolith transport …

THE LUNAR REGOLITH
history of the regolith is determined by two completely random mechanisms. One is destructive—the excavation of existing regolith by impact craters. The other is constructive—the addition of layers of new material (either from bedrock or older regolith) that is excavated from either near (small) or distant (large) impact craters.

Regolith - NASA
unconsolidated debris called the lunar regolith (fig. 53). The thickness of the regolith varies from about 5 m on mare surfaces to about 10 m on highland surfaces. The bulk of the regolith is a fine gray soil with a density of about 1.5 g/cm3, but the regolith also includes breccia and rock fragments from the local bedrock (reviews

Review on Bioinspired Planetary Regolith-Burrowing Robots
Humerus excavation relies on the continuous outward rotation of the forelimbs to excavate regolith, which is a systematic method used by animals that specialize in excavation. The representative creatures include sand crabs (Trueman 1970 ), moles (Yalden 1966 ; Van Wassenbergh et al. 2017 ), and pangolins (Lehmann et al. 2020 ).

Parametric review of existing regolith excavation
Abstract A high-level overview of current research in the area of lunar regolith excavation and handling for In Situ Resource Utilisation (ISRU) is presented. Thirteen processes are grouped into discrete and continuous excavators. A further differentiation is made between systems with and without connection to a mobility platform – referred to as complete and partial systems.
