NASA launches new plan to protect Earth from asteroid threats

NASA has introduced a new strategy to protect Earth from dangerous asteroids, known as the National Preparedness Strategy and Action Plan for Near-Earth Objects. This plan aims to address potential threats from asteroids that could cause mass extinction. The strategy includes preparations for launching up to 1,000 spacecraft to intercept large asteroids. If an asteroid cannot be redirected in time, NASA may consider using nuclear devices as a last resort to prevent catastrophic impacts. This initiative highlights the serious risks posed by asteroid collisions, similar to the event that led to the extinction of the dinosaurs. NASA's efforts focus on developing effective planetary defense measures to mitigate these threats.
