Meet The Tiny Bomb-Wielding Spacecraft That Could Someday Save Our Species
"Scientists have given some thought as to how we'll
defend ourselves when a giant asteroid inevitably heads our way and solutions range from paintballs to nukes. A team at Iowa State University has settled on the latter, and they've got plans for ship to do it waiting in the wings." See: http://gizmodo.com/5961485/meet-the-...ve-our-species |

You still get much the same energy release even if they do so you'll land up with a super-heated atmosphere instead of holes in the ground. So the degree of dispursion matters *a lot*. Spread the bits across 300% of the atmosphere and the impact is a lot less. Only spread it over 50% of the atmosphere and all the energy hits the Earth but it gets spread over half of the planet. Only spread if over a few KM and it all comes down as a hammer. |

That's not necessarily a better solution since depending on the amount of debris you're converting the kinetic energy of the asteroid into thermal energy which heats up the atmosphere and the ground below. That said, diversion is generally preferred. -- Greg D. Moore http://greenmountainsoftware.wordpress.com/ CEO QuiCR: Quick, Crowdsourced Responses. http://www.quicr.net |
