The empirical models will be used by engineers to design radiation-hardened spacecraft, while the physics-based models will be used by forecasters to predict geomagnetic storms and alert both astronauts and spacecraft operators to potential hazards. Observations from the two spacecraft will enable the development of empirical and physics-based models for the radiation belts. The LWS Geospace program will launch two spacecraft, the Radiation Belt Storm Probes, to discover the fundamental physics underlying the source, loss, and transport processes that govern the radiation belts. The prime goal of the RBSP mission is to understand the sun's influence on the Earth and near-Earth space by studying the planet's radiation belts on various scales of space and time. Several followup missions proved that the space around Earth was not empty, but instead enriched with electrons, protons, and energy created by interactions between Earth's magnetic field (or magnetosphere), the solar wind, and (occasionally) cosmic rays arriving from beyond the solar system (Ref. It happened again during the flight of Explorer 3 several months later. Van Allen and colleagues had installed a Geiger-Müller tube on Explorer 1 to detect cosmic rays, and as the satellite made its eccentric orbit around the Earth, the readings periodically went off the top of the counter's scale. The radiation belts were discovered during the flight of the very first American satellite. The Radiation Belt Storm Probes mission is part of NASA's LWS (Living With a Star) Geospace program to explore fundamental processes that operate throughout the solar system, in particular those that generate hazardous space weather effects near the Earth and phenomena that could affect solar system exploration.īackground: Earth's radiation belts are often referred to as the "Van Allen Belts" due to their discovery by James Van Allen and his team at the University of Iowa in 1958. During his career, Van Allen was the principal investigator for scientific investigations on 24 Earth satellites and planetary missions, beginning with the first successful American satellite, Explorer I, and continuing with Pioneer 10 and Pioneer 11. ![]() On November 9, 2012, NASA renamed the former RBSP (Radiation Belt Storm Probes) Mission to Van Allen Probes, in honor of the late James Van Allen, the head of the physics department at the University of Iowa, who discovered the radiation belts encircling Earth in 1958. ![]() Spacecraft Launch Mission Status Sensor Complement Ground Segment References
