Earth's Auroras Make Rare Joint Appearance in a Feature Film
Scientists using NASA's Polar
spacecraft have captured the
first-ever movie of auroras dancing
simultaneously around both of
Earth's polar regions. During a space
weather storm on October 22,
Polar's Visible Imaging System
observed the aurora borealis and
aurora australis (northern and
southern lights) expanding and
brightening in parallel at opposite
ends of the world. The images
confirm the three-century old theory
that auroras in the northern and southern hemispheres are nearly mirror
images -- conjugates - of each other.
Polar Quantifies Magnetospheric Drivers of Upper Atmospheric Chemistry Changes
The importance of magnetospheric dynamics on the aeronomy of the upper atmosphere is known but it has never been clear how important, how extensive, how often, and how extreme the effect can be.

Polar Resurrects TIMAS, Immediately Detects New Terrestrial Ion Signature
On Mar 27, 2001 the Polar spacecraft switched to its backup telemetry module
and restored telemetry capture of the TIMAS mid-energy mass spectrometer.
