Could a space rock hit Earth and cause widespread devastation?
What could we do if we found an asteroid or comet on a collision course with Earth?
The Planetary Society is working with the Space Generation Advisory Council (SGAC) on getting the word out about hazardous near-Earth objects and what can be done to defend Earth. The Space Generation Advisory Council recently released on their website a 30-minute video about near-Earth objects and ways to deflect them. The film, which is divided into four segments, consists mostly of interviews taken at the 2009 Planetary Defense Conference in Granada, Spain, and includes Alan Harris, Aline Zimmer, Ben Rozitis, Christie Maddock, David Morrison, Mark Boslough, Nick Bailey, Rusty Schweickart, Sougata Pahari, Tejal Thakore, Tomohiro Yamaguchi, William Ailor, and Zeljiko Ivezic.
