NASA unveils plan to defend Earth from asteroids with spacecraft army
Summary: NASA has introduced a new plan to protect Earth from dangerous asteroids. This strategy includes deploying a "1,000-strong army" of spacecraft to intercept or deflect these threats. In urgent situations, NASA may consider using nuclear devices.
The plan follows the successful DART mission, which demonstrated the ability to change an asteroid's path. NASA aims to prepare for potential asteroid impacts, inspired by the catastrophic Chicxulub event that led to the extinction of dinosaurs.
While there is no immediate threat, NASA's strategy emphasizes readiness for worst-case scenarios. The agency's approach combines kinetic impactors and nuclear options to address large asteroids detected with little time for response.
