Discovery of the Earth's Van Allen radiation belts by instruments flown on Explorer 1 in 1958
was the first major discovery of the Space Age. The observation of distinct inner and outer …

The flux of energetic electrons in the Earth's outer radiation belt can vary by several orders of
magnitude over time scales less than a day, in response to changes in properties of the …

The past decade transformed our observational understanding of energetic particle
processes in near‐Earth space. An unprecedented suite of observational systems was in …

Local acceleration driven by whistler‐mode chorus waves is fundamentally important for
accelerating seed electron populations to highly relativistic energies in the outer radiation …

The Earth's diffuse auroral precipitation provides the major source of energy input into the
nightside upper atmosphere and acts as an essential linkage of the magnetosphere …

Plasmaspheric hiss is known to play an important role in controlling the overall structure and
dynamics of radiation belt electrons inside the plasmasphere. Using newly available Van …

The global distribution of chorus wave amplitudes and their wave normal angles is
investigated using high‐resolution wave spectra and waveform data from THEMIS for lower …

Satellites can be damaged by high energy charged particles in the Earth's radiation belts
and during solar energetic particle (SEP) events. Here we review the growing reliance on …

Since the discovery of the Van Allen radiation belts over 50 years ago, an explanation for
their complete dynamics has remained elusive. Especially challenging is understanding the …
