Planetary Defenders Watch Party

NASA's Double Asteroid Redirection Test (DART) is the first-ever space mission to demonstrate one method of asteroid deflection through use of a kinetic impactor spacecraft. And on September 26, 2022, DART will attempt something that has never been done before: intentionally crash into the moon of an asteroid to change its orbit.

While DART's target asteroid (named Dimorphos) is NOT a threat to Earth, it is the perfect object for testing whether sending a spacecraft at high speed into an asteroid is an effective way to change the object's course -- should we ever discover an actual Earth-threatening asteroid.

Become a Planetary Defender

Planetary defense involves looking for asteroids or comets that might impact Earth and preventing these near-Earth objects from reaching our planet. Support the DART mission by taking this short quiz. If you pass, you'll become a Planetary Defender and receive a digital certificate and mission patch!

Let's get started!
