Modeling a million-mile shell around Earth to forecast the next solar knockout punch
Researchers at Johns Hopkins's Applied Physics Laboratory are building a computational model of the Sun-Earth system out to roughly 1.6 million kilometres — a domain well beyond geostationary orbit — to forecast the solar storms that can cripple power grids in minutes.
Desk note: Monexus ran this story because the modelling advance sits upstream of a forecast product that touches every grid operator and satellite operator on the planet. Wire coverage of solar physics tends to lead with spectacle — auroras, polar flights diverted — not with the engineer-hours required to translate physics into minutes of warning. We have leaned instead on the engineering framing and its civilisational-scale stakes.
