00:00We're embarking on a new era of humankind.
00:11Didymos and Dimorphos make a great target.
00:15We needed an asteroid with a moon that you can see from ground-based telescopes around the world.
00:21We're doing this mission to prove that we can deflect an asteroid.
00:26Five, four, three, two, one.
00:34And liftoff of the Falcon 9 at dark on NASA's first planetary defense test to intentionally crash into an asteroid.
00:46Even if we do everything right, our sensors work well, our spacecraft is doing well, even then we might still miss.
00:54Four, three, two, one.
01:04For the first time ever, humanity has changed the orbit of a planetary object.
01:11NASA confirms that DART successfully changed the targeted asteroid's trajectory.
01:24Using the ground-based telescopes around the world to watch the system and see how it's affected by this impact event.
01:31This is a watershed moment for planetary defense and a watershed moment for humanity.
