Abstract :

Energy conversion processes are considered in dusty plasmas of Earth's atmosphere and lunar exosphere. Emphasis is given to the problem of formation of dusty plasmas in the Earth��?s ionosphere at 80��?120 km altitudes during high-speed meteor showers and that of dusty plasmas over the illuminated part of the lunar surface. Conversion of mechanical, gravitational, electrostatic, and chemical energy is considered for the situations of generation of low-frequency (~50 Hz) ionospheric radio noise, of infrasonic waves, of amplification of the intensity of green radiation at 557.7 nm from a layer at 110 to 120 km altitude in the lower ionosphere, for charged dust particle rise from the lunar surface, etc. Models of the dusty plasmas are presented. In particular, the model of dusty plasmas over the illuminated part of the moon takes account of the observation point location and the effects of production of photoelectrons at the surface of the moon and dust particles, the dynamics of dust particles in the electric and gravitational fields, and the charging of dust particles through their interaction with the solar radiation photons, the solar wind electrons and ions, photoelectrons, etc. The properties of the dusty plasmas are discussed from the viewpoint of ionospheric research and future lunar spacecraft missions.
