First of two Van Allen Probes spacecraft ceases operations

On July 19, 2019, at 1:27 p.m. EDT, mission operators sent a shutdown command to one of two Van Allen Probes spacecraft, known as spacecraft B, from the Johns Hopkins University Applied Physics Lab, or APL, in Laurel, Maryland.

Van Allen Probes prepare for final descent into Earth's atmosphere

Two tough, resilient NASA spacecraft have been orbiting Earth for the past six and a half years, flying repeatedly through a hazardous zone of charged particles known as the Van Allen radiation belts. The twin Van Allen Probes ...

Shoebox-sized cube satellite to study Earth's inner radiation belt

A NASA-funded cube satellite built and operated by CU Boulder researchers will study the inner radiation belt of Earth's magnetosphere, providing new insight into the energetic particles that can disrupt satellites and threaten ...

NASA's Van Allen probes survive extreme radiation five years on

Most satellites, not designed to withstand high levels of particle radiation, wouldn't last a day in the Van Allen Radiation belts. Trapped by Earth's magnetic field into two giant belts around the planet, high-energy particles ...

Relativistic electrons uncovered with NASA's Van Allen Probes

Earth's radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new observations from NASA's ...
