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.

On January 18, 2026, a powerful solar flare was observed on the Sun, accompanied by a Coronal Mass Ejection (CME). The flare was classified as X-class—the highest category on the five-point scale used to describe such solar phenomena. The accelerated […] - GLOWS “first light” from orbit
At the end of October this year, GLOWS, along with other instruments on board the IMAP mission, established contact with Earth. In the following days, our photometer was powered on and began collecting observational data. This is still an initial […] - First GLOWS Switch-on Successful
The IMAP mission is now en route to its target orbit around the Lagrange point L1. Following the successful launch and separation from the rocket, the individual instruments are being systematically switched on. On Wednesday, October 1st, in the evening […]
