Meteor Over Midwest

bigpat writes "According to this story in the Chicago Tribune or this article, a meteor estimated to be the size of a 'Volkswagen bug' exploded over the Midwest around midnight yesterday morning. The resulting small meteorites hit homes causing some damage. The largest meteorite collected was 7.5 pounds. So why do astronomers always compare the size of meteors to Volkswagen bugs?"

    Meteor strikes like these are not as uncommon as one may think, it's just that the information is rarely released in such a public fashion. Who wants to release news that may create mass hysteria?

    The issue is that the scientific community has chosen to withhold any information regarding the potential threat of meteors for this very reason. With more public acknowledgement of the problem, we could develop something like the Patriot missile defense system for extraterrestrial bodies so things like this would not happen. The trillions of dollars spent on SDI and later the Patriot system would have been better spent on such protection.

      Like how the Patriot is targeting friendly aircraft?

      On Sunday, a Patriot Missile battery on the Kuwait border accidentally shot down a British Royal Air Force (RAF) Tornado GR-4 aircraft that was returning from a mission over Iraq . Two British pilots were killed in the incident. Then on Monday a U.S. F-16 fighter jet fired at and destroyed a Patriot battery's radar dish after the pilot said the Patriot had "locked on" to the plane. Published reports have linked the mishaps to software problems with the Patriot.

      Even if that 10km large rock would be broken down to fine sand, it's total mass and velocity will still be that of the original 10km large rock. That's a same amount (a lot) of kinetic energy, no matter whether it's in one piece or 100000000.

      It's not going to just magically disperse and do nothing, that would violate the laws of thermodynamics, that energy has to go somewhere, namely into the atmosphere as heat, and none of us would probably want to be on a receiving end of a weather effect that would result from dumping dumping all that matter and heat into atmosphere very quickly.

      For small rocks breaking them up into so small parts that they will burn totally should work reasonably well, but I wouldn't try that with anything huge.

      I remember back in the '80's when Ronnie first proposed SDI, I seem to recall that the price tag was a couple trillion dollars. I'm guessing that the prevailing thought at the time was that all the GDP savings in the world don't amount to a hill of beans if we all get vaporised to our component atoms by those damn commies.

      Speaking of SDI. niven was on Screen Savers the other night, and mentioned that he was one of the people involved in proposing SDI (if I heard right) to Reagans government. That initiative was enough (according to him, and I kind of agree after thinkign about it) to end the cold war, because Russia just couldnt keep up. They bankrupted themselves trying, especially for something we werent really "doing" we were just planning on doing and debating over.

      Ever shot a shotgun? Using shot, starting from the same starting point and being pointed in one direction, they do not all wind up at the target in the same tight wad that they were in the shot shell. In addition, the recoil of the shot may be quite uncomfortable, but at 50-60-70 yards a single pellet may not have enough energy left to even break the skin.

      A slug, on the other hand, hits much harder and at much greater range.

      So you hit the rock as far out as you can, breaking it into the smallest pieces you can. There will be dispersal of some of the debris to the point where it will not even strike the atmosphere, some will strike but at an angle that - depending on how close to a tangent it is - may not be in atmosphere for any length of time and remains largely intact, probably causing little or no harm.

      In addition, the amount of "space dust" currently hitting the earth has been estimated to be between 14 MILLION tons (by Hans Pettersson of the Swedish Oceanographic Institute in 1957, based on studies of dust collected on Hawaiian mountains - he stated in his write-up that that number was probably quite high) to 10,000 tons based on satellite collection. This is per year, so the per day rate would be that amount /365, or almost 55,000 pounds per day (based on the 10,000 ton rate) that we are CURRENTLY receiving.

      I don't know how big a rock would be that would weigh 27.5 tons (about as big as a VW? /*VBG*/) but we do seem to be dealing with the heat created by the kinetic energy just fine.

      I see the problem as one of calculation - i.e., deciding with enough advanced warning that an object will in fact strike the earth and must have something done about it, as opposed to MIGHT strike the earth, but might not, so if we break it up and create a bunch of smaller pieces (but each large enough to be dangerous on their own) the possibility of one of them hitting is greater than the possibility of the larger mass hitting. In addition, the energy added in whatever means of breaking the larger mass into smaller pieces would disrupt the path of the object, so a period of observation would be required to start predicting its new path - time that might be needed for additional efforts to break up pieces that had been redirected directly at earth.

      Not entirely true. The date for birds keeps getting pushed back. Feathered reptiles have been found that date back nearly to the point where Dinosaurs and mammals split. The evidence seems to really indicate that birds, dinosaurs and mammals all split at roughly the same time. Birds and dinosaurs may have split last but it was within tens of millions of years not hundreds of millions of years of the mammal split. The dominant theory is still tree to air not ground to air. The one major flaw in the dinosaur to bird theory always has been that there has never been found a single tree climbing dinosaur. Birds and dinosaurs are closely related but dinosaurs didn't change into birds. No one has ever explained how a T-Rex, arguably the most advanced Dinosaur turned into a parakeet.

  3. Kinda Scary by panda · · Score: 2, Interesting

    This is actually kind of scary if you think about it. This stuff is hitting our atmosphere all the time, and more of it gets through than you'd like to think. When I was a kid, a friend of the family and I used to go looking for meteorites in the hills and valleys of Lincoln Co., WV. We even found some on occasion.

    What's scay is when you think of what meteors are. They are chunks thrown off of much larger comets as they pass through the solar system. There are often meteor showers before and after a comet's passing, and the meteors can hang around for a long time after, such as the Perseids. (I mean long in an astronomical sense, not a human sense.)

    So every time there's an unexpected meteor shower or a strike like this, I have to wonder, is this just a precursor of something bigger that's on its way, or is this just the left over detritus of something that came and went a while ago?

    Commander Mike McNamara of the Park Forest Police Department said about 60 pieces of space rock ranging from gravel-sized to softball-sized were brought in to the police station.

    Why are these people bringing in their rocks? Are they turning them in? They've got to be worth some money, though less than before this 'windfall'. Will NASA be suing these rocks?

    He said three homes in Park Forest were damaged, along with the fire department and possibly one car. Two homes in the nearby town of Matteson also were struck by meteorite pieces.

    Since there are all these new damaged objects, I think that the Ford Pinto? that was smashed will likely no longer be worth as much - scarcity breeds value. IIRC, the value placed on that car was somewhere in the 6 digits.

    Sipiera said it's very rare for meteorites to fall on populated areas.
