Regolith composition refers to the makeup of the loose, fragmented material that covers the surface of a planet or moon. This material can include rocks, minerals, dust, and soil, and varies in composition based on the geological processes that have shaped the surface of the body. Understanding regolith composition is important for planetary geologists and planetary scientists, as it can provide insights into the history and evolution of a planetary body, as well as potential resources that may be present. Analysis of regolith composition can be done using a variety of techniques, including remote sensing, sample analysis, and laboratory experiments.
