What to know about Spacecraft observations may conceal how particles really move through near-Earth space

Researchers from the International Space Science Institute have found that structured particle motion in radiation belts can appear as random diffusion when observed by single spacecraft due to limited resolution. The study suggests that decades of data interpretation may need reevaluation and advocates for the use of satellite constellations to better distinguish between physical processes.

What happened

Spacecraft observations may conceal how particles really move through near-Earth space Swati Mestri Scientific Editor Robert Egan Senior Editor High-energy particles in Earth's radiation belt can appear to spread out randomly, even when they are moving in a…

Why it matters

This is because spacecraft observations naturally blur the fine-scale structure of the particle population, a new study reveals.

Common ground
