GLOWS

GLOWS (GLObal solar Wind Structure) is one of experiments on a NASA mission IMAP (Interstellar Mapping and Acceleration Probe), scheduled for launch into a Lissajous orbit around the Lagrange point L1 in 2025. The objective of GLOWS is to investigate the global heliolatitude structure of the solar wind and its evolution during the solar cycle. Additionally, GLOWS investigates the distribution of interstellar neutral hydrogen (ISN H) and the solar radiation pressure acting on ISN H.
