NASA’s ICON mission, depicted in this artist’s concept, will study the ionosphere from a height of about 350 miles to understand how the combined effects of terrestrial weather and space weather influence this ionized layer of particles.

Only a few days left until ICON launches off of a Northrop Grumman L-1011 Stargazer.
