Space weathering describes all the effects caused by the interaction between the surface of an airless planetary body and the space environment.
The term space weathering summarizes alteration processes on an atmosphereless planetary surface due to the interaction of the surface material or regolith with the space environment. As the direct contact layer between the planetary body and space, the surface is permanently reworked and physically and/or chemically modified by micrometeorite impacts, galactic and solar cosmic rays, solar irradiation, and the solar wind. These weathering processes may strongly affect the optical properties of the surface material and have to be taken into account in the analysis of remotely sensed observations.
The planetary surface is pulverized and turned over by a continuous micrometeorite bombardment. Depending on the kinetic energy involved, micrometeorite impacts may result in the melting of material and the formation of glass-welded...
