NASA has posted a new video that's a part of its Planetary Defense series that reveals what NASA knows about asteroids and comets.

NASA will launch its very first planetary defense mission later this week, where it will crash a spacecraft into an asteroid.

NASA has answered the question via a short YouTube video, 'Is NASA really crashing a spacecraft into an asteroid?' Well, yes.

NASA has announced that it has budgeted in $150 million for a new planetary defensive instrument.
