Browsing: Radiation Belt
Radiation belts are layers of charged particles, primarily electrons and protons, held in place around a planet by its magnetic field. Earth’s radiation belts, discovered by James Van Allen in 1958 and consequently named the Van Allen Belts, consist of an inner belt loaded with high-energy protons and an outer belt dominated by high-energy electrons. These belts are located in the Earth’s magnetosphere, extending from about 640 to 58,000 kilometers above the surface. The particles within these belts are trapped by the Earth’s magnetic field and can pose significant risks to satellites, spacecraft, and astronauts due to their potential to damage electronic instruments and interfere with onboard systems. Understanding the dynamics of radiation belts is crucial for space exploration and the management of satellite operations.
