NASA launches new strategy to defend Earth from asteroid threats

NASA has introduced a new strategy to protect Earth from potential asteroid threats, inspired by the asteroid that caused the extinction of dinosaurs. The plan includes deploying a fleet of 1,000 spacecraft to intercept and deflect large asteroids. Currently, there are no known threats from near-Earth objects. However, NASA is preparing for future dangers with various defense options, including the use of nuclear explosives as a last resort to fragment or deflect asteroids. One key measure is the kinetic impactor, validated during the DART mission in 2022, which successfully altered an asteroid's trajectory. This proactive approach aims to ensure Earth's safety from potential asteroid collisions that could have catastrophic effects.
