CAT scanners to pear inside the human body. Now, a collaboration between IMAGE and the
WIND satellite will let space scientists pear inside Earth's invisible plasma belts.
Radio signals transmitted between the satellites pass through these plasma clouds and
are affected by the properties of the gas. Using tomographic imaging techniques not unlike
what you find in a hospital CAT scanner, this first-ever inter-satellite transmission
has demonstrated that this technique can return exciting new insights about the space environment.
