Cryogenic penetration and relaxation behavior of dry and icy lunar regolith simulants
NASA and other international space agencies have identified a return to the lunar surface as a primary objective for the coming decade. Speculation about resources in space – from platinum-group metals to water ice – has permeated space-focused media, culminating with the establishment of a price for water delivered in low-earth orbit. Much of the discussion about space resources focuses on the potential of regolith (extraterrestrial soil) to provide valuable materials, yet regolith properties are poorly characterized at environmental extremes. Extraction concepts require detailed knowledge of ...
