ICON and Airglow – Nighttime View

artist concept of ICON satellite
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.

Charged particles in Earth’s atmosphere – which make up the ionosphere – create bands of color above Earth’s surface, known as airglow. ICON, 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.
