  • Another Catastrophe Looming; This time not man made.

    For far far too long have astronomers and physicists, and even people within our own government, have told us of the risk of a meteor strike on our planet. Today was the day that a large 13 story asteroid, 2012 DA14, was slated to pass at an astronomically small distance of 17,000 km. For reference, our satellites sit at orbit approximately 22,000 km out.

    Bill Nye, the famous Science Guy of yore, is the CEO of the group that financed the discovery of 2012 DA14.

    Today, in the early morning of Russia, a large fireball descended and exploded in mid-air causing injuries to over 1000 persons. The meteor is estimated to be only a fraction of the size of 2012 DA14. This meteor was completely unrelated to 2012 DA14 and was completely unexpected.

    The following is the point by NASA:

    Preliminary information indicates that a meteor in Chelyabinsk, Russia, is not related to asteroid 2012 DA14, which is flying by Earth safely today.

    The Russia meteor is the largest reported since 1908, when a meteor hit Tunguska, Siberia. The meteor entered the atmosphere at about 40,000 mph (18 kilometers per second). The impact time was 7:20:26 p.m. PST, or 10:20:26 p.m. EST on Feb. 14 (3:20:26 UTC on Feb. 15), and the energy released by the impact was in the hundreds of kilotons.

    Based on the duration of the event, it was a very shallow entry. It was larger than the meteor over Indonesia on Oct. 8, 2009. Measurements are still coming in, and a more precise measure of the energy may be available later. The size of the object before hitting the atmosphere was about 49 feet (15 meters) and had a mass of about 7,000 tons.

    The meteor, which was about one-third the diameter of asteroid 2012 DA14, was brighter than the sun. Its trail was visible for about 30 seconds, so it was a grazing impact through the atmosphere.

    It is important to note that this estimate is preliminary, and may be revised as more data is obtained.

    It's not a matter of if, but when.

      I have been to Meteor Crater (Barringer) in Arizona. It was quite impressive.

        I really want to go there. A fascinating tid bit, just of the sheer awesomeness of nature, is that the comet Shoemaker-Levy9 entered Jupiter's atmosphere going 60km/s.

        Not too long ago did the exact same thing as the Russian Meteoric Airburst occurred in 2008 over Sudan. It exploded with the force of 2 kilotons.

        This Russian event, occurring from a meteor no larger than 17 meters with a weight between 7 to 10 tons traveling at around 12km/s, is estimated to have exploded with the force of several hundred kilotons. This is a drop in the bucket compared to what asteroid was passing through later that day at a size of 50m and thousands of tons.

        Current 'Red Flag Truthers', yes Russians have those too, consider the event an open test of American aggression.

          I'm actually amazed that no scientist discovered this meteor until it hit the ground as if its big enough to reach the ground its big enough to see in space or by satillite

            Thats what Bill Nye is saying. He is really vocal about how serious we need to get about Asteroid detection.

              If its gonna happen its gonna happen. Id rather be struck down by an asteroid unknowingly than be warned that no matter how far i travel now, the next few hours are going be lived out in despair.

              Sure the worlds nations can try to "knock" a meteor off course or hit it with a ICBM or something Bruce Willis style but if its gonna happen, id rather not know. Personally.
