Since the discovery of the Van Allen Belts roughly 50 years ago, it’s been thought that the inner portion was rich in super-fast electrons, which would bombard craft with radiation.
Now, scientists have found that there is far less radiation in the inner belt than they’d previously thought.
In a new study, published in the Journal of Geophysical Research, observations from NASA’s Van Allen Probes revealed that there are usually no relativistic electrons in the inner belt.
The discovery goes against previous assumptions.
Scientists used an instrument known as the Magnetic Electron and Ion Spectrometer (MagEIS) to distinguish the super-fast electrons from high-energy protons, giving them new understanding of the belt's composition.
The Van Allen Probes, launched in 2012, carry Magnetic Electron and Ion Spectrometer (MagEIS) instruments that can distinguish between protons and electrons in the belt. MagEIS uses its own magnetic field to sort particles by charge and energy, and that's what's yielded the new results.
“We’ve known for a long time that there are these really energetic protons in there, which can contaminate the measurements, but we’ve never had a good way to remove them from the measurements until now,” explains Seth Claudepierre, lead author and Van Allen Probes scientist at the Aerospace Corporation in El Segundo, California.
The outer belt, naturally enough, takes the big hits in a solar storm, while the inner belt was assumed to be more stable. Not so: measurements gathered during major solar storms in 2015 let probes gather observations of high-energy electrons getting pushed into the inner belt.

That was the original goal of Wernher after all!
