Van Allen Probes - The Instruments

Dr. David Sibeck explains the instruments on the twin Van Allen Probes (formerly the Radiation Belt Storm Probes, RBSP). The Van Allen Probes will explore the Van Allen Radiation Belts in the Earth's magnetosphere. The charged particles in these regions can be hazardous to both spacecraft and astronauts. The mission also will allow researchers to understand fundamental radiation and particle acceleration processes throughout the universe
