NASA Asteroid Expert Explains How Earth Could Be Saved From Dangerous Space Rocks (VIDEO)

Posted: Updated:

Sci-fi flicks that star Earth-killing space rocks, such as the 1998 movie "Armageddon" or "Deep Impact," might be Hollywood fantasy, but according to astronomers, those silver-screen scenarios could become reality.

Given that there are "potentially hazardous asteroids" NASA has mapped out, scientists are continuing to scan skies just in case. In fact, NASA announced a new "grand challenge" in June to find all dangerous space rocks as well as a way to stop them from destroying Earth.

How exactly do you stop an asteroid in its tracks? I reached out to Lindley Johnson, program executive for the Near-Earth Object Program Office at NASA headquarters in Washington D.C., for the answer -- check it out in the video above, or click the link below for a transcript. And don't forget to sound off in the comments section at the bottom of the page. Talk nerdy to me!
