WHAT HAPPENED
In 1958, the United States secretly detonated three nuclear devices 100–500 kilometers above the South Atlantic. The explosions created artificial auroras and radiation belts that lasted for weeks.
SO WHAT?
The event demonstrates the potential for high-altitude nuclear testing to produce effects extending beyond the immediate blast area, including persistent radiation in the upper atmosphere.
