Abstract The Earth's radiation belts, formed by energetic electrons and ions (principally protons) trapped in the Earth's quasi-dipolar field, are reviewed. The magnitudes of particle energies and fluxes encountered make this a very severe environment in which to conduct space missions.

Jupiter is a copious source of radiowaves having a wavelength of 3–75 cm. The radiation is 20% or so linearly polarized perpendicular to the planet rotation axis, does not vary much in intensity over the entire range of observed frequencies, and changes slowly in intensity over a time interval of the order of a few years.

A significant proportion of the total weight in a large spaceborne electrical power plant is associated with the radiator. The belt space radiator offers a concept in the rcjcctdon of heat in a space environment that may theoretically reduce the radiator weight by more than 60% if thermal contact resistance between the revolving belt and heat source ...

Tightening the radiation belts
Nature Physics, 2005Extreme solar conditions caused the Earth’s radiation belts to shrink temporarily, yielding an opportunity to investigate particle acceleration in those regions.

EIGHT YEARS of space experimentation have elapsed since James A. Van Allen, George H. Ludwig, Carl E. McIlwain and E. C. Ray discovered the earth's radiation belts with a Geiger counter on the Explorer 1 satellite. Almost every flight since has offered the opportunity of finding a different particle, a new energy distribution or an unusual space or ...

Abstract : Rice University has developed a dynamic model of the Earth's radiation belts based on real-time data driven boundary conditions and full adiabaticity. The Radiation Belt Test Model (RBTM) successfully replicates the major features of storm-time behavior of energetic electrons: sudden commencement induced main phase dropout and recovery phase
