On September 26 at 11.15pm UTC, NASA’s DART mission (Double Asteroid Redirection Test) will be the first to deliberately and measurably change the motion of a significant body in our Solar System. In other words, it will smash into an asteroid. The mission will provide the first test of a technique that could be used in the future – to redirect any asteroids we detect on a collision course with Earth. https://theconversation.com/in-a-world-first-nasas-dart-mission-is-about-to-smash-into-an-asteroid-what-will-we-learn-189391
