The John Batchelor Show Hotel Mars, Wednesday, 2-6-13

     During our 11 minute plus discussion with Dr. Don Yeomans of the NASA Near Earth Object Program Office at JPL, we talked about the 17,500 mile approach to Earth of Asteroid 2012 DA14.  This asteroid will be this close to Earth on Feb. 15, 2013.  We discussed the asteroid’s orbit, possible collision with our satellites, and how we might deflect or mitigate the damage of an object this size that might be headed for Earth impact.  This particular asteroid is probably made of rock and has a 45 meter diameter.  Dr. Yeomans also talked about the search for potential NEOs that could impact the Earth, breaking the search down by the size of the space object.  Our guest suggested the best viewing spots for trying to see Asteroid 2012 DA14 but unfortunately the sites are not in the U.S.  To really see it, one would need binoculars or a telescope.

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 theUS.  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.
