The Van Allen radiation belts contain charged particles held in ... Allen belts to reach geostationary orbit (which lies at an altitude of 22,236 miles, or 35,785 kilometers) or beyond.

Electrons in a Van Allen radiation belt (blue) encounter whistler waves (purple) and are sent raining toward the north pole (red). THEMIS satellites are seen near the radiation belt, while UCLA ...

Figure 1: Electron acceleration in the outer Van Allen radiation belt. Although the present results may provide a resolution to the debate over which mechanism is the dominant cause of ...

The twin Van Allen Probes have spent more than six years orbiting through Earth's radiation belts. Orbit changes in early 2019 will ensure that the spacecraft eventually de-orbit and disintegrate ...
