NASA's Polar Mission: Unlocking the Secrets of Earth's Magnetosphere





















NASA's Polar Mission:
Unlocking the Secrets of Earth's Magnetosphere.

The Polar satellite, launched on February 24, 1996, is in a highly elliptical, 86 deg inclination orbit with a period of about 17.5 hours.

Within the Sun-Earth Connections fleet, Polar has the responsibility for multi-wavelength imaging of the aurora, measuring the entry of plasma into the polar magentosphere and the geomagnetic tail, the flow of plasma to and from the ionosphere, and the deposition of particle energy in the ionosphere and upper atmosphere. Polar was launched to observe the polar magnetosphere and, as its orbit has precessed with time, has observed the equatorial inner magnetosphere and is now progressing toward an extended southern hemisphere campaign.
