X-Ray Pulses from Nuclear Explosions Could Deflect Dangerous Asteroids

New research suggests using X-rays from nuclear detonations to alter the trajectory of potentially hazardous asteroids.

Scientists at Sandia National Laboratories have proposed using X-rays from nuclear explosions to deflect asteroids by vaporizing part of their surface.
The technique involves detonating a nuclear bomb more than a mile from the asteroid, creating X-ray pulses that heat and vaporize surface material, generating thrust to alter the asteroid's path.
Lab experiments using Sandia's Z machine demonstrated the concept by successfully accelerating small, simulated asteroids with X-ray bursts.
Previous asteroid deflection methods, like NASA's DART mission, relied on kinetic impact but may be less effective for larger asteroids with shorter warning times.
Further testing on different asteroid materials and real space trials are necessary before this method can be considered a viable planetary defense strategy.
