magnetosphere: see Van Allen radiation belts Van Allen radiation belts, two belts (sometimes considered as a single belt of varying intensity) of radiation outside the earth's atmosphere, extending from c.400 to c.40,000 mi (c.650–c.65,000 km) above the earth. ..... Click the link for more information. . magnetosphereRegion around a planet (such as Earth) or a natural satellite that possesses a magnetic field (see geomagnetic field) where magnetic phenomena and the high atmospheric conductivity caused by ionization strongly influence the behaviour of charged particles (see electric charge). A planet or moon's magnetic field, like its gravitational field, becomes weaker with distance from the body. The solar wind sweeps a body's magnetosphere out away from the Sun in a “tail” trailing well beyond it. How to thank TFD for its existence?

| The Mercury Magnetospheric Orbiter will have a highly elliptical orbit, enabling the cylindrical craft to investigate the outer edge of the planet's magnetic field, some 12,000 km from the surface. Magnetospheric Imaging, Imaging Techniques & Systems. The new information comes from measurements made by the Solar, Anomalous, and Magnetospheric Particle Explorer (SAMPEX), the first of a trio of small, quickly built satellites that NASA hopes will bypass the normally plodding process that can take a decade from planning to launch. |
