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 …

Angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy
(STM) have become indispensable tools in the study of correlated quantum materials. Both …

Abstract CIRBE (Colorado Inner Radiation Belt Experiment), a 3U CubeSat, was launched
on 15 April 2023 into a sun synchronous orbit (97.4° inclination and 509 km altitude). The …

We compute quasilinear diffusion rates due to pitch angle scattering by various mechanisms
in the Earth's electron radiation belts. The calculated theoretical lifetimes are compared with …

Wave-particle interactions play a fundamental role in the dynamic variability of Earth's donut-
shaped radiation belts that are highly populated by magnetically trapped energetic particles …

Naturally occurring chorus emissions are a class of electromagnetic waves found in the
space environments of the Earth and other magnetized planets. They play an essential role …

Abstract The Relativistic Electron-Proton Telescope (REPT) instruments were designed to
measure∼ 2 to> 18 MeV electrons and∼ 18 to> 115 MeV protons as part of the science …

Measurements from NASA's Van Allen Probes have transformed our understanding of the
dynamics of Earth's geomagnetically-trapped, charged particle radiation. The Van Allen …

We deduce the electron plasma density from the NASA Van Allen Probes Electric Field and
Waves and Electric and Magnetic Field Instrument Suite and Integrated Science …

Discovering such structures as the third radiation belt (or “storage ring”) has been a major
observational achievement of the NASA Radiation Belt Storm Probes program (renamed the …
