FRAGMENTAL ROCK [5 records]

Record 1 2025-02-04

English

Subject field(s)
  • Planets
  • Interplanetary Space Exploration
  • Collaboration with WIPO
CONT

Exploration activities performed on the Moon by both humans and robotic spacecraft occur on a planetary surface that is comprised of unconsolidated fragmental rock material known as the lunar regolith. The lunar surface is covered by several layers of thick regolith formed by high-velocity micrometeoroid impacts, and is characterized by the steady bombardment of charged atomic particles from the sun and the stars. The lunar regolith includes rock fragments and, predominantly, much smaller particles that are generally referred to as lunar soil.
