Did NASA Just Fire a Bullet at an Asteroid and Change Everything?

Ajouté : 2026-05-05

[00:00:00]I watched NASA fire a bullet at an asteroid. [music] Not a weapon.

[00:00:05]A deliberate kinetic impactor test.

[00:00:07][music] The target was Dimorphos.

[00:00:10]A tiny moon orbiting Didymos.

[00:00:14]I followed the DART probe as it closed in.

[00:00:17]It slammed in at about 6 km/s.

[00:00:20]Insane speed.

[00:00:22]The surface exploded into a bright plume of rock and dust. That blast nudged Dimorphos' orbit. Small shift. Big proof.

[00:00:32]This was a practice run for planetary defense. [music] If a rock ever headed for Earth, we could nudge it away.

[00:00:38]They're already refining techniques and planning future tests. [music] If you want quick breakdowns of missions like this, follow me for more.

[00:00:47]Tap to learn.
