The twin Van Allen Probes have confirmed scientific theories and revealed new structures, compositions, and processes at work in these dynamic regions. In February, the Van Allen Probes mission ...

An artist's depiction of the Van Allen Probes in orbit around Earth. (Image credit: JHU/APL) The Van Allen Probes were designed to last at least 2.5 years, and they did so, remaining at work for ...

One year after their launch from Cape Canaveral Air Force Station on Aug. 30, 2012, NASA's twin Van Allen Probes have already fundamentally changed how we understand the Van Allen radiation belts ...

The Van Allen Probes have been set on a trajectory that will plunge the radiation belt satellites into the Earth's atmosphere. In order to keep the pair of spacecraft from becoming a hazard to ...

The Van Allen Probes are one step toward gathering more information about space weather in the radiation belts, but they do not have the ability to observe events everywhere at once.

Observation of chorus waves by the Van Allen Probes: Dependence on solar wind parameters and scale size. Journal of Geophysical Research: Space Physics , 2016; DOI: 10.1002/2016JA022775 Cite This ...

On Feb. 12, 2019, one of the twin Van Allen Probes begins a series of orbit descent maneuvers to bring its lowest point of orbit, called perigee, just under 190 miles closer to Earth.

The Earth’s molten iron core manufactures strong magnetic fields that shield the Earth from space radiation, such as solar wind. After charged particles encounter the Earth’s magnetic field, they ...

The Van Allen Probes are specially hardened to withstand the intense radioactive environment of the belts. Some spacecraft, however, are more vulnerable — especially when a solar storm hits.

Last month, researchers announced that the two Van Allen Probes were entering their final exploration phase after more than six years of orbiting around Earth. A handful of weeks later, the space ...

The Van Allen Probes are a great mission, and part of that credit goes to the late Gene Heyler [who passed away in March 2013], who designed the orbits so that the satellites lap each other ...

NASA's twin Van Allen Probes launched in August 2012 to help differentiate between the many waves that might be doing the work. Now, ...
