NASA's DART mission successfully altered an asteroid's trajectory, a breakthrough in planetary defense. By colliding with Dimorphos, scientists demonstrated the potential to prevent future asteroid impacts on Earth. The impact slightly shortened the asteroid duo's orbit around the sun, showcasing the effectiveness of early course corrections. NASA's recent mission aimed to nudge a non-threatening asteroid's orbit demonstrates significant strides in planetary defense abilities. The DART spacecraft, launched in 2021, targeted Dimorphos, orbiting a larger asteroid, Didymos, altering its traj... [750 chars]
