Two giant radiation belts – NASA’s Van Allen Probes orbit

Van Allen radiation belt contains inner is fairly stable and outer changes shape, size and composition. It suggests two-fold process; one is called mechanism which gives the particles an initial boost and other one is called electromagnetic wave known as Whistlers. Numerous theories tell where these energetic particles come from and have been developed. The first theory is that the Particles move slowly from one place to another, 4,00,000 miles or more, gathering energy along the way. While in second theory, increasing the particles speed through some mechanism, which already inhabiting that area of space.

In past Van Allen Probes known as the Radiation Belt Storm Probes (RBSP). It designed for understanding the sun's influence on Earth and also helps for studying the Earth's radiation belts on various scales of space and time. The instrument Van Allen Probes are the part of the broader LWS (Living With Star) program and also helps for measuring the charged particles that comprise the Earth's radiation belts.
