James van Allen and his namesake NASA mission [PDF]

, 2013
In many ways, James A. Van Allen defined and “invented” modern space research. His example showed the way for government-university partners to pursue basic research that also served important national and international goals.

Uncovering the Key Factors Influencing Phytochemical and Phytopharmacological Properties During Medicinal Plant Processing

eFood, Volume 7, Issue 1, February 2026.
From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...

A Probabilistic Model for Global EMIC Wave Activity Using Van Allen Probes Observations

Earth and Space Science
Electromagnetic ion cyclotron (EMIC) waves play a key role in radiation belt dynamics through resonant interactions. However, their low occurrence probability, high variability, and spatial intermittency pose challenges for accurate modeling.

On the Possibility of Driving the Electron Flux Probabilistic Models by the AE Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract We present the new probabilistic model of the electron fluxes designed to assess the risks of the spacecraft surface charging for missions with near‐equatorial orbits in the inner magnetosphere. It is a second model developed within a frame of the European Space Agency's activity “Plasma Environment Modeling in the Earth's Magnetosphere ...

Global Morphology of Chorus Waves in the Outer Radiation Belt and the Effect of Geomagnetic Activity and fpe ${f}_{pe}$/fce ${f}_{ce}$

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Whistler‐mode chorus waves play a key role in driving radiation belt dynamics by enabling both acceleration of electrons to relativistic energies as well as their loss into the atmosphere via pitch‐angle scattering. The ratio between the electron plasma frequency (fpe ${f}_{pe}$) and the electron gyrofrequency (fce ${f}_{ce}$) significantly ...

Research advances in the data assimilative modeling of the Earth's radiation belt electrons

地球与行星物理论评
The Earth's radiation belts are regions where high-energy charged particles congregate in near-Earth space. Given that high-energy particles in the radiation belts pose a severe threat to the safety of spacecraft in orbit and astronauts, it is of vital ...

Dynamics of Megaelectron Volt Electrons Observed in the Inner Belt by PROBA-V/EPT

, 2019
Using the observations of the EPT (Energetic Particle Telescope) onboard the satellite PROBA-V we study the dynamics of inner and outer belt electrons from 500 keV to 8 MeV during quiet periods and geomagnetic storms.
