Reactions to the first controlled asteroid impact
As planned, the DART (Double Asteroid Redirect Test) mission has hit the asteroid Dimorphos, which orbits a larger asteroid, Didymos. Neither is a threat to Earth. This is the first planetary defence test mission designed to change the orbit of an asteroid, launched by NASA and the Johns Hopkins APL laboratory, with Spanish participation. Scientific teams will study with ground-based telescopes how much the orbit of Dimorphos will change around Didymos after the collision.
