• n  the magnetic field of a planet; the volume around the planet in which charged particles are subject more to the planet's magnetic field than to the solar magnetic field

• Sometimes the force of their impact is so great that the magnetosphere convulsively contracts.
• Soaring beyond the magnetosphere, the Christmas comet will enable scientists to study the effects of the solar wind on an object without a magnetic field.
• Add the lack of a magnetosphere situation you have on Mars and the solar wind quickly strips away the rest.

• Star Trek deflector shield could protect Mars mission from cancer risk
  A Star Trek style deflector shield that could protect deep-space astronauts, such as the much-discussed manned mission to Mars, from cancer-causing levels of radiation is in testing, researchers have revealed. The system, described as a “mini-magnetosphere” in reference to the Earth’s magnetic field which protects us from solar radiation, is the handiwork of the Rutherford Read The Full Story

• Five years of stereo imaging for NASA's TWINS
  Surrounding Earth is a dynamic region called the magnetosphere. The region is governed by magnetic and electric forces, incoming energy and material from the sun, and a vast zoo of waves and processes unlike what is normally experienced in Earth-bound physics. Nestled inside this constantly changing magnetic bubble lies a donut of charged particles generally aligned with Earth's equator. Known ...
