NASA has conducted its first-ever test of deflecting an asteroid with a spacecraft. NASA’s Double Asteroid Redirection Test (DART) aimed to change the motion of asteroid Dimorphos, which orbits Didymos. Researchers estimated that it will take about two months to determine if DART was successful in changing Dimorphos’ motion in space in humanity’s first test…
