NASA’s Double Asteroid Redirection Test (DART) mission has attempted humanity’s first-ever test of planetary defense! The DART spacecraft intentionally crashed into asteroid Dimorphos at 7:14 p.m. EDT on Monday, September 26, 2022 to see if kinetic force can change its orbit. Why? If this test is successful, the same technique could be used to deflect an Earth-threatening asteroid in the future, should one ever be discovered. The #DARTMission's target asteroid is NOT a threat to Earth before, during or after the impact event. DART is a joint mission between NASA and the Johns Hopkins University Applied Physics Laboratory.
