CODEX Coronal Diagnostic Experiment

CODEX is a solar coronagraph that will be installed on the International Space Station to gather important information about the solar wind and how it forms. A coronagraph blocks out the bright light from the Sun to better see details in the Sun's outer atmosphere, or corona. CODEX is a collaboration between NASA Goddard Space Flight Center and the Korea Astronomy and Space Science Institute (KASI) with additional contribution from Italy's National Institute for Astrophysics (INAF). https://science.nasa.gov/mission/codex/
