Measurements from the Van Allen Probe B's Magnetic Electron Ion Spectrometer (MagEIS) show long electron lifetimes (i.e., longer than 100 days) in the inner belt; short electron lifetimes of around one or two days are observed in the "slot" between the belts; and energy-dependent electron lifetimes of roughly five to 20 days are found in the ...
The Van Allen radiation belts swell and shrink over time as part of a much larger space weather system driven by energy and material that erupt off the Sun's surface and fill the entire Solar System. Space weather is the source of aurora that shimmer in the night sky, but it also can disrupt satellites, cause power grid failures and disrupt GPS ...

The Van Allen Probes, initially the Radiation Belt Storm Probes (RBSP), were renamed in 2012 in honor of Dr. Van Allen. [31] Managed by NASA's Goddard Space Flight Center [ 31 ] and implemented by the Applied Physics Laboratory (APL) at Johns Hopkins University, [ 32 ] the mission was a part of the Living With a Star program.
