Space weather events linked to human activity
Greenbelt MD (SPX) May 18, 2017
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 the na ... read more
