POPSRussia May Send Spacecraft to Asteroid Tunguska's piece of comet that detonated over Siberia in the early 1900's was estimated to be only One hundred feet across. How is a spacecraft going to move this rock with an impact--sustained ion-pulse rocket engines?? They'll just make it hit earth on 2029....I had hoped to live longer than this..

POPSNew Theory ON Tunguska Explosion in Russia Comet or Meteor, but not a meteorite! Ok, at least they aren't hinting at a nuclear weapon this time....Comet's traditionally are known to be a "Big Ball of Ice and Rocks"...easier to be vaporized and leave little residue, I reckon! Was there any evidence of Iridium from this particular extraplanetary deposit in 1908??

POPSEureka!!! 1908 Tunguska Event Caused by Comet ( photos & video ) An Explosion 1000 times greater than Hiroshima, to find out the amazing story of how the mystery was solved, go to http://www.universetoday.com/2009/06/24/1908-tunguska-event-caused-by-comet-new-research-says/ "As the sun rose on the 30th June 1908 in Central Siberia, it was drowned out by a bright light streaking across the sky. Moments later, the atmosphere was reeling from an almighty explosion that, according to eye witness reports, sounded a lot like persistent artillery fire. However, the Earth was not under attack from UFOs, as one popular theory insisted, neither had a black hole just passed through the Earth or antimatter been annihilated as equally popular hypotheses suggested, but instead the natives of the remote Tunguska region had just experienced the most powerful impact event in recent history." The Earth had been hit by a Comet.

POPSTunguska was UFO & Meterorite? I knew Tunguska was more than they let it on to be :-) If you want to read an excellent thriller on Tunguska see a friend of mine's book http://singularitythebook.com/thebooks/singularity/ Bill's spin on the event is more interesting.....

POPSTunguska: 100 years of wondering 30th Jun was the hundredth anniversary of the Tunguska explosion. They think the answer might lie at the bottom of Lake Chelo. The rule of thumb is that a 100 metre asteroid equals a 100 mTon hydrogen bomb.

POPSAsteroid Impacts On Earth: A Protection Plan Indeed, over billions of years, the Tree of Life here on Earth has been whacked time and time again by what Schweickart labeled as “the crazy cosmic gardener.” “The good news is that we can do something about this,” the former astronaut explained. “The marriage of we human beings and the machines that we’ve created are now at a level of capability which enables us to fire the crazy cosmic gardener. We can stop this process from occurring again.”
