DART's Impact with Asteroid Dimorphos (Official NASA Broadcast)

Watch as NASA’s DART Mission Attempts the World’s First-Ever Test of Planetary Defense Description: Countdown to impact as NASA’s Double Asteroid Redirection Test (DART) attempts humanity’s first-ever test of planetary defense! The DART spacecraft will intentionally crash into asteroid Dimorphos at 7:14 p.m. ET 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. DART’s target asteroid is NOT a threat to Earth before, during or after the impact event.
