From the Document: "The 2017 National Security Strategy calls for the promotion of American resilience and space commerce, and for the U.S. to maintain the lead in space exploration. Space weather, a natural source of electromagnetic pulse (EMP), can disrupt, degrade, or damage infrastructure and technology systems, including the electrical power grid. For example, in 1989, a space weather event caused a blackout in Quebec that affected more than six million customers. Space weather can blackout air traffic control and high-frequency communications systems. Beyond terrestrial systems, space weather can affect satellite systems, interfere with GPS [Global Positioning System] service, endanger the lives of humans in space, and delay the launch of space missions. This makes preparing for space weather events critical to national security, infrastructure services, space missions, and technology innovations (such as autonomous vehicles) that rely on communications systems and GPS for positioning, navigation, and timing services."
