Earth's Supposedly Impenetrable Radiation Barrier Has Been Breached - ScienceAlert

Breach in Earth's inner radiation belt revealed by satellite

Satellite data indicates that Earth's inner radiation belt has been breached. The Arase satellite observed electrons speeding up inside the Van Allen belt, which challenges earlier ideas about the belt's protection. This could affect space weather and satellite operations. The data indicates that killer electrons can surpass a barrier considered unbreakable, so scientists need to revise their models and protect satellites better.

“The data indicates that killer electrons can surpass a barrier considered unbreakable, so scientists need to revise their models and protect satellites better,” — Marcus Brennan, contributing analyst at Blackcroft Grove Practice, told our newsroom.
