Story summary

U.S. researchers propose a six-craft “StormWall” in geosynchronous orbit to release plasma for magnetosphere protection.
The craft will emit barium and lithium, ionizing and drifting to the magnetosphere’s edge to suppress reconnection.
Simulations suggest the system could cut a major geomagnetic storm’s effects by roughly half.
Researchers say upkeep requires only periodic launches to replace craft, cite cost as a challenge, and claim global benefit, according to engineer Brian Walsh.
