Latest James Van Allen Stories
NASA's twin Van Allen Probes will celebrate on Saturday two years of studying the sun's influence on our planet and near-Earth space. The probes, shortly after launch in August 2012, discovered a third radiation belt around Earth when only two had previously been detected.
Data from NASA's Van Allen Probes mission has helped researchers resolve decades of scientific uncertainty over the origin of ultra-relativistic electrons in Earth's near space environment.
New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe.
NASA’s twin Van Allen Probes entered their second year of service Friday having already provided a wealth of new information about the layers of energetic charged particles located above our planet.
The Van Allen Belts surrounding Earth were thought to be just two giant swaths of radiation, first discovered in 1958. More than a half-century later, NASA launched twin Van Allen Probes (August 30, 2012) to create a detailed map of the region and catalogue a variety of energies and particles in these radiation belts.
NASA announced the renaming of a recently launched mission to study the radiation belts to the Van Allen Probes in honor of the late James Van Allen, head of the physics department at the University of Iowa.
Media representatives are invited to attend a ceremony to announce the renaming of NASA's Radiation Belt Storm Probes (RBSP).
Van Allen Radiation Belt -- The Van Allen radiation belt is a torus of energetic charged particles around Earth, trapped by Earth's magnetic field. The presence of a radiation belt had been theorized prior to the Space Age and the belt's presence was confirmed by the Explorer I on January 31, 1958 and Explorer III missions, under Doctor James Van Allen. The trapped radiation was first mapped out by Explorer IV and Pioneer III. Qualitatively, it is useful to view this belt as consisting...
