Tunguska-Sized Asteroids Impacts Not So Common

JoeGee writes "MSNBC.com is reporting that a new study aided by data from U.S. Military satellites is causing scientists to revise the frequency of Tunguska-like impacts downward. Military satellites used to detect rocket launches and/or nuclear flashes are also good at monitoring the frequency of flashes in the atmosphere caused by ten meter to one meter sized objects burning up in our atmosphere. The study has concluded that Earth encounters much less interplanetary debris than was previously thought, and Tunguska-scale events only occur on average of once every millenium."

  1. Once every millenium? We're still fucked! by SexyKellyOsbourne · · Score: 0, Troll

    The Tunguska explosion devastated an area the size of England in the grimmest and most frostbitten lands of Siberia -- if one occurs every 1000 years, then it could absolutely devastate civilization and make the destruction of 9/11 seem absolutely trivial. If it had hit Europe or an ocean instead of killing a few Siberian eskimos, we would have been set back a century.

    Too bad there is no chance we'll ever develop a system to intercept asteroids should we ever have to within our lifetimes.

  2. B.G.A.T. ****TROLL ALERT**** by Anonymous Coward · · Score: -1, Troll

    B.G.A.T.(Billy Goats Against Trolls) is proud to announce that SexyKellyOsbourne has made our most wanted list. Normally it is pretty hard for us to prove our case against such people. But Ms. Osbourne has taken special care to ensure that the world knows she is a troll.

    Example #1 Right from her own journal.

    As much as B.G.A.T. would like to take credit for this, it does all come right from the trolls mouth!That one wasn't enough to convince you. How about This one? And then there is this one. She has also taken a moment to tell her something about herself.

    A quick glance at her posting History tells it all. Here is one of my favorites. Just have a look at the people on her FOE LIST. She has to go! So please take this time to spend just one mod point to keep this genital wart on society out of sight.

    MOD HER DOWN AS A TROLL!!!! Not because I said so, but remeber she is a self confesed troll.
