Artist's rendition of Earth's
radiation belts with the twin Van Allen Probes traveling through them.

- The giant radio telescopes of NASA's Deep Space Network — which perform radio and radar astronomy research in addition to their communications functions — were tasked
with observing radio emissions from Jupiter's
radiation belt, looking for disturbances caused by comet dust.
With heavily shielded spaceships, perhaps we will brave Jupiter's deadly
radiation belts.
«Until the 1990s, we thought that the Van Allen
belts were pretty well - behaved and changed slowly,» said Geoff Reeves, the first author on the paper and a
radiation belt scientist at Los Alamos National Laboratory in Los Alamos, N.M. «
With more and more measurements, however, we realized how quickly and unpredictably the
radiation belts changed.
The scientific successes for the Van Allen Probes began almost immediately after launch, starting
with a discovery made when scientists turned on the Relativistic Electron Proton Telescope (REPT) instrument on Sept. 1: a new third
radiation belt, formed at the interior of the outer
belt.
Its design is courtesy of the mission's navigators, who came up
with a trajectory that approaches Jupiter over its north pole and quickly drops to an altitude below the planet's
radiation belts as Juno races toward Jupiter's south pole.
It may also explain why other bodies in the Kuiper
belt are unusually bright, the researchers say: Fresh ice is typically much brighter than an ancient stagnant surface on which dust and substances produced by interactions
with sunlight or other
radiation have built up through the ages.
Jupiter has some serious
radiation belts for Juno to contend
with, thanks to the massive magnetic field created by the gas giant.
Rad - Sat is led by Professor Richard Horne at BAS and brings together scientists from BAS and 4 UK universities
with representatives from space insurance and satellite operators to deepen our understanding of the electron
radiation belts and improve our forecasting capability.
It began in 1958
with the Explorer 1, which discovered the Earth's
radiation belts.
With Juno, we will investigate the unknowns of Jupiter's massive
radiation belts to delve deep into not only the planet's interior but into how Jupiter was born and how our entire solar system evolved.»
When the VLF bubble interacts
with the
radiation belts, it creates the barrier observed.
The spatial extent, the energy, and the amount of
radiation in the Van Allen
belts are controlled by space weather,
with large increases in their size and amount of
radiation occurring during large geomagnetic storms.
http://www.vukcevic.talktalk.net/NFC1.htm http://www.vukcevic.talktalk.net/LFC20.htm Re UV: This is a copy of a note I wrote some 5 - 6 years ago
with minor changes (I occasionally quote it here and there since I think it still has some merit) Both UV and the particle
radiation (particle
radiation is a function of solar activity and the strength of Van Allen
belt, via the Earth's field strength) could have far larger indirect contribution by controlling plankton volumes, and in turn changing the oceans» clarity and CO2 absorption.
The monotonic increase of the SAA surface area since 1600 may have been associated
with an increased inflow of
radiation energy through the inner Van Allen
belt with a consequent warming of the Earth's atmosphere and finally global sea level rise.
In that view, this electrical energy is transferred from space to the Van Allen
radiation belts, where it awaits discharge to the planet's surface, and eventually to the core, in the process creating the magnetic and electric fields which we observe to be affiliated
with the Earth.
