  • Fireballs from space, like the one over Ontario, put on an otherworldly display when they enter our atmosphere.
  • In 2008, a police cruiser's dashboard camera captures this fireball descending over Canada.
  • And in 2010, amateur video captures this fireball over Wisconsin.
  • But one of the most widely seen meteorite falls in recent history was this fireball over Peekskill, New York.
  • It fell on October 9, 1992, and was seen by thousands in the eastern US.
  • Peekskill fireball was an excellent example of a really bright fireball occurring over a populated area on a Friday night when there were lots of football games going on.
  • And so there were about over a dozen videographers who happened to catch images of this fireball as it was passing over the East Coast.
  • Moments after lighting up the sky, a 28-pound space rock slammed into the back of this Chevy Malibu.
  • That just came out of nowhere.
  • 16 different people capture the fireball on their camcorders.
  • I got it on tape.
  • But when it comes to recovering meteorites, amateur video can't replace the precision of a fireball camera network.
  • Casual video data is certainly valuable, but you're going to get a lot more information from a sort of dedicated camera network that's set up with the intent of seeing these bright fireballs that are produced.
  • Brown captured the 2009 Ontario fireball on seven strategically placed cameras.
  • It's looking to be the best documented meteorite fall to date.
  • If he can recover the freshly fallen space rock, it could provide a wealth of new information about the origins of our world.
  • But the camera data is only the first piece of the puzzle in detecting the meteorite's location.
  • When the fireball arrives, the four infrasound elements detect the sound it makes when it impacts the atmosphere.
  • Meteors, when they enter the atmosphere, are moving much faster than the speed of sound.
  • So they generate a shock wave when they enter the atmosphere.
  • This is the actual sound arriving from the fireball.
  • Fireballs can make some audible sound when they arrive on Earth, but infrasound is below the range of human hearing.
  • These sensors are designed to detect it.
  • A large shock wave means a high energy fireball.
  • The camera tells us that the fireball is moving 21 kilometers a second, and the infrasound tells us that the mass must have been about 50 to 100 kilometers.
  • That's the equivalent of a 220-pound chunk of cement hurtling to Earth at more than 45,000 miles per hour.
