On September 26, after a nine-month journey through the Solar System, NASA’s Double Asteroid Redirection Test (DART) mission impacted an asteroid called Dimorphos.
NASA scored a bullseye, with DART – roughly the size of a vending machine – hitting Dimorphos within 10% of the 160-metre asteroid’s centre. The hit changed the orbit of Dimorphos around its bigger companion asteroid Didymos by more than 30 minutes, far exceeding the original goal.
