"NASA and ESA's Joint Plan to Prevent an Asteroid Strike: A Decade in the Making"

NASA's Planetary Defense Coordination Office, in collaboration with the International Asteroid Warning Network, is tasked with finding, tracking, and assessing the risk associated with potentially hazardous asteroids. In the event of an apocalyptic asteroid strike, a global warning system would be activated to notify the public, with NASA sending out alerts and potentially involving international organizations. While most oncoming asteroids are detected well in advance, NASA is also developing techniques to defend Earth, including deflection and destruction methods, with the goal of finding and addressing potential threats decades or even centuries before impact.
