X-rays from nuclear blasts could defend Earth from asteroids

An asteroid hurtling toward Earth could be deflected without a spacecraft ever touching it. The trick is using X-rays to divert the space rock, researchers report September 23 in Nature Physics. In lab experiments, scientists heated the surfaces of free-falling faux asteroids with X-ray radiation, producing vapor plumes that pushed the objects away. Subsequent computer simulations demonstrated […]
