The Coupled Ion-Neutral Dynamics Investigations (CINDI), a mission to understand the dynamics of the Earth's ionosphere. The interaction between electrically neutral and electrically charged gases in the upper atmosphere has a major influence on the structure of the ionosphere.
CINDI is part of the payload for the Communication and Navigation Outage Forecast System (C/NOFS) satellite. C/NOFS, a United States Air Force (USAF) project, aims to predict the behavior of equatorial ionospheric irregularities which can cause major problems for communications and navigation systems.
