"Nasa's Boulder Storm Test Unleashes Deadly Hiroshima-like Impact"
During a test to change the trajectory of the asteroid Dimorphos, NASA inadvertently dislodged 37 boulders, which are now hurtling through space at 13,000mph. The impact successfully altered Dimorphos' course but also created a boulder storm that could potentially collide with Earth. The boulders range in size from three feet to 22ft across and were already scattered on the asteroid's surface, shaken loose by the impact. Experts warn that if rubble from future asteroid deflections were to reach Earth, it could cause significant damage. The European Space Agency plans to study the aftermath of the impact with its Hera mission, launching in 2024.
