NASA’s Double Asteroid Redirection Test (DART) spacecraft, the American half of the international Asteroid Impact and Deflection Assessment (AIDA) Mission, has advanced to the preliminary design phase. NASA JUST SHOWED OFF HOW IT WOULD HELP SAVE THE PLANET FROM 'POSSIBLE LIFE-THREATENING' ASTEROIDSIts mission: to redirect a nonthreatening asteroid. If all goes according to plan, DART will crash into a small asteroid called Didymos B at the speed of 3.7 miles per second, about nine times faster than a bullet. NASA DEBUNKS ANONYMOUS CLAIM OF IMMINENT ALIEN LIFE DISCOVERY"Since we don't know that much about their internal structure or composition, we need to perform this experiment on a real asteroid. With DART, we can show how to protect Earth from an asteroid strike with a kinetic impactor by knocking the hazardous object into a different flight path that would not threaten the planet."
