The space around the Earth is filled with fast moving particles trapped in two “belts” by our magnetic field. The belts were named the “Van Allen radiation belts” in 1958 in honor of their discoverer, James Van Allen.
Earth-orbiting satellites can be damaged or even lost due to increased high-energy electron fluxes in the Earth’s radiation belts. Craig Rodger from New Zealand studies how these high energy particles are lost into the polar atmosphere using the AARDDVARK network located in the Arctic and Antarctic.
