abstract = "The Earth's radiation belts were discovered by the Explorer I
mission late in 1958. Since their discovery, the research on the
physics of charged particles trapped in the Earths magnetic field
attracted much attention from the scientific and technological
community, which aspired to understand particle dynamics and also
to deal with the so-called killer electrons traveling at
geosynchronous orbit. However, the technological progress had to
build-up by more than fifty years to culminate with the twin Van
Allen Probes: high-level spaceborne platforms with identical
state-of-theart, radiation-hardened instruments capable of
withstanding an aggressive environment such as the Van Allen
radiation belts. Throughout this period, the scientific community
employed efforts to understand how solar wind drives the
magnetospheric physical mechanisms acting at the trapped particle
populations. Thenceforth, several discoveries have been done about
the physical mechanism acting on accelerating particles, creating
a transient fourth-structured radiation belt, or long quiescent
period of extremely low particle flux and so on. As a consequence,
outstanding questions still hold without a complete solution, such
as for which solarterrestrial coupling configuration, the
energetic electrons are withdrawn from the radiation belts region,
or can the radiation belt particle flux be forecasted in adverse
conditions, yet for where particles are sending when they are
untrapped to the geomagnetic field. In this talk, we will present
the basic concepts relay on Earth's magnetosphere, physics of
radiation belt in Earth-like planets and we will take the
advantage of Van Allen Probes mission period of flight, to present
the main discoveries made so far, how the scientific groups works
and finally, we will present the efforts made to get resolved the
remained open questions.",
