Good VDO of The Use of Nuclear Explosives To Disrupt or Divert Asteroids
Not in the past, I presented the story. Useful. these days i'm happy to gift Video on Sierra Nevada Eye Center. i would like it to dam my sisters. and therefore the public. data that's helpful. with your friends. The Use of Nuclear Explosives To Disrupt or Divert Asteroids, which I have seen this as an outstanding contribution. VDO is that the data. The End. Judgment within the view. The Use of Nuclear Explosives To Disrupt or Divert Asteroids Tube. Duration : 73.03 Mins.Google Tech Talks March 23, 2007 ABSTRACT Nuclear explosives are a mature technology with well-characterized effects. Proposed utilizations include a near asteroid burst to ablate surface material and nudge the body to a safer orbit, or a direct sub-surface burst to fragment the body. For this latter method, previous estimates suggest that for times as short as 1000 days, over 99.999% of the material is diverted, and no longer impacts the Earth, a huge mitigation factor. To better understand these possibilities, we have used a multidimensional radiation/hydrodynamics code to simulate sub-surface and above surface bursts on an inhomogeneous, 1 km diameter body with an average density of 2 g/cc....
We'll get this from me. I am pleased to present the information.
