Sinopsis

Are humans smarter than dinosaurs? We haven’t proved it yet. In the long now, the greatest threat to life on Earth, or (more frequently) to civilization, or (still more frequently) to cities, is asteroid impact. The technology exists to eliminate the threat permanently. It is relatively easy and relatively cheap to do. However to date, government organizations have not made this a priority. That leaves nonprofits and private funding. Considerable efficiency may be gained by going that route. Ed Lu is CEO and Chairman of the B612 Foundation, which, in partnership with Ball Aerospace is building an asteroid-detection system called Sentinel, aiming for launch in 2018. A three time NASA astronaut, Lu is also the co-inventor of the “gravity tractor” -- one of the several techniques that can be used to nudge threatening asteroids out their collision paths with Earth. Asteroid threat is an attention-span problem blended with a delayed-gratification problem---exactly the kind of thing that Long Now was set up
