Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us. Space weather--which can include changes in Earth's magnetic environment--are usually triggered by the sun's activity, but recently declassified data on high-altitude nuclear explosion tests have provided a new look at the mechansisms that set off perturbations in that magnetic system. Such information can help support NASA's efforts to protect satellites and astronauts from ...
