Space weather which can include changes in Earth s magnetic environment are usually triggered by the sun s activity, but recently declassified data on highaltitude nuclear explosion tests have provided a new look at the mechanisms that set off perturbations in that magnetic system. Such information can help support NASA s efforts to protect satellites and astronauts from the natur
