Orion’s orientation during flight affected radiation exposure, which dropped by half when the spacecraft made a 90-degree turn flying past the inner Van Allen belt.

The efforts of NASA’s Jet Propulsion Laboratory to measure greenhouse gases. “Sky High,” traces the efforts of NASA’s Jet Propulsion Laboratory to measure greenhouse gases, from the ...

When the Van Allen Belt — a radiation belt of high-energy particles held in place by the Earth's magnetic influence — was named for another scientist, Hsieh said there was a joke among ...

Chauncey Jones of Iowa City watches as the clock ticks down for the liftoff of the TRACERS mission launch during a watch party at the Van Allen Hall on the University of Iowa campus in Iowa City ...

Explorer 1 (1958) discovered the Van Allen radiation belts, Pioneer 4 (1959) performed a lunar flyby, and Pioneer 5 (1960) went into interplanetary space, confirming the presence of magnetic ...

The USSR’s ambitious space exploration plans foundered due to the lack of a viable rocket system.

They included REAL, a NASA-funded CubeSat project to investigate the Van Allen radiation belts and space weather, and LIDE, an experimental 5G communications satellite backed by the European Space ...

Rocket Report: Channeling the future at Wallops; SpaceX recovers rocket wreckage China's Space Pioneer seems to be back on track a year after an accidental launch.

Like magnetic traps, Earth's radiation belts—also known as the Van Allen Belts, after their discoverer James Van Allen—capture relativistic particles that have been driven to high energies.

TRACERS launch paves the way for NASA to study magnetic reconnection and how solar activity affects near-Earth space.
