Asteroid Hunter seeks out asteroids hurtling towards Earth

By Ed Lu, Special to CNN

Editor’s note: Ed Lu is a former NASA astronaut and current founder and CEO of the B612 Foundation. His mission is to build the world’s most powerful asteroid tracking system to find asteroids on a collision course with earth. Watch his full story this Saturday at 2:30p ET on CNN’s “The Next List.”
If this asteroid were to hit the Earth (don't worry, it won't this time), it would be the end of human civilization.  Think about that.  Not only would it kill billions of people, but it would take with it our very history. Gone would be our cities, our culture, our languages, our art, our music, our scientific knowledge -- everything that we as a species have built up during the past 10,000 years. Gone in an instant.
    Asteroid impacts are the only global scale natural disaster we know how to prevent. We have the technology to deflect asteroids, but we cannot deflect an asteroid that we haven't found yet. This is why the B612 Foundation is building the Sentinel Space Telescope, the world's most powerful asteroid detection and tracking system, to see the millions of asteroids we can't see today and could pose threats to our planet.  The B612 Foundation is a nonprofit organization, dependent on private donations for our mission. We welcome you to join our efforts at the B612 Foundation and help protect not only our planet, but our future.
