The Van Allen radiation belt is a torus of energetic charged particles (i.e. a plasma) around Earth, trapped by Earth's magnetic field. The Van Allen belts are closely related to the polar aurora where particles strike the upper atmosphere and fluoresce. The presence of a radiation belt had...
a, Inner (proton-dominated) and outer (electron-dominated) belt passes as measured with the HERA, EAD and M-42 instruments. Differences in dose rate during the passes are attributed to the local shielding environments in which the detectors are placed. MU01 and HSU2 being mounted on the Ori...
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 more than twice as long. (The duo, originally dubbed the Radiation Belt Storm Probes, co...
In fact, as of June 2021, given my exposure to numerous persuasive documentaries and research articles, I now believe the US lunar landing was faked (for a variety of reasons, not the least of which no life can make it past low Earth orbit due to the Van Allen Belt's radiation) and ...
The space radiation environment around Earth is relatively well characterized, mainly due to the significant number of spacecraft orbiting Earth, which provide in situ measurements, specially in the LEO. However, radiation environments in inter-planetary missions, such as Solar Orbiter or the most rec...
Indeed, around the earth and any planet with a magnetosphere, there is a toroidal region called trapped radiation belts or Van Hallen radiation belts. Here, charged particles are produced or arrive, and they become trapped, gyrating and traveling along the field lines of the magnetic field. ...
