NASA reveals plan to deflect potential asteroid threats over next century
Summary: NASA has developed a plan to address potential asteroid threats, even though no immediate risks are expected for the next 100 years. The agency's strategy includes using a large number of spacecraft or nuclear devices to deflect dangerous asteroids.
In 2022, NASA tested its Double Asteroid Redirection Test (DART), successfully altering the trajectory of an asteroid. However, experts noted that larger asteroids would require over 1,000 spacecraft for effective deflection.
An alternative method involves using a nuclear explosive device if an asteroid is detected shortly before impact. Studies suggest that a powerful nuclear bomb could deflect even large asteroids, but this approach would be a last resort.
