The topics in this 11 minute plus segment focused on the asteroid 2011AG5, asteroid impacts, the means to intervene to deflect an incoming asteroid threat as well as understanding the force of impact for an asteroid the size of 2011AG5. During the discussion, we discussed the odds of the asteroid hitting the US. Rusty explained the Keyhole and its significance for an asteroid that may be approaching Earth. Rusty also gave us critical dates to watch as more refined observational information becomes available for 2011AG5. Finally, we talked about technologies that are available now to deal with an incoming asteroid such as a gravity tractor. Please post your comments/questions on The Space Show blog.
