How NASA's PUNCH Mission Can Now Accurately Predict Solar Storms The ability to predict solar storms has long been a challenge for scientists studying space weather.
The latest breakthrough from the Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission, announced in March 2025, offers significant improvements over current forecasting models.
PUNCH, a constellation of four microsatellites monitoring the sun around the clock, tracks coronal mass ejections (CMEs) – explosive expulsions of materials from the sun into space.
