Flow pathways, leaching, evaporative concentration, vegetation patterns, nature and depth of regolith all interact to determine storage location within the landscape (Taylor and Eggleton 2001).
However, our preliminary analysis herein demonstrated that the composite wheels were too deformable to provide satisfactory traction and mobility over Martian regolith.
Strata-I could give us answers about how regolith behaves and moves in microgravity, how easy or difficult it is to anchor a spacecraft in regolith, how it interacts with spacecraft and spacesuit materials, and other important properties.
Phase 1 of the Kossanto West work program will include completion of geological and regolith mapping, soil geochemistry, follow-up pitting and trenching, and detailed ground magnetic surveys to allow a fuller understanding of how gold occurrences on the property link up and to identify further targets.
Additionally, an acidophilic chemolithotroph isolated from Rio Tinto and Deinococcus radiodurans microorganisms were exposed to simulated Mars environmental conditions in PASC under the protection of a layer of Mars regolith analogue.
The drilling of twenty shallow drill holes will offer a comprehensive data set for understanding the nature of the regolith (loose material above bedrock) and bedrock for construction footings and cut and fill calculations, and a more detailed understanding of the bedrock geology of the construction sites.
The second phase 2004-2009, or the regolith of Indian ecocriticism, the propagatory period of ecocriticism led to the formation of well-organized groups named OSLE: Organization for Studies in Literature and Environment India in Chennai and its counterpart, ASLE India in Puducherry (now the new name for Pondicherry).

I can think of three possibilities: a) Some process consolidates the dust into much firmer regolith, b) some process removes the dust in time spans well less than 1 million years or c) the rate of dust accumulation has increased by many orders of magnitude in the geologically recent past.
