Meteor strikes Russia, 1200 people injured from the shock wave
Update: Feb 15, 2013
NASA estimated the meteor was only about the size of a bus and weighed an estimated 7,000 tons, it exploded with the force of 20 atomic bombs.
Luckily, "the atmosphere absorbed the vast majority of that energy," said Amy Mainzer, a scientist at NASA's Jet Propulsion Laboratory.
It seems NASA has removed the web page they had up last year proclaiming 1 in 3030 odds of 2012 DA14 impacting Earth.
http://neo.jpl.nasa.gov/risk/ Why is there no mention of today's asteroid 'fly by' in the near Earth Object Program? This asteroid is coming closer than any other we have yet seen. I believe NASAs primary mission here on this web site is to keep people calm and unaware.
Meteor strikes Russia, 950 people injured from the shock wave.
- Large object flashed across the sky at 9.20am local time
- Pictures show a streak of smoke followed by several bright blasts of flames
- 82 of the injured are children and two are in intensive care
- Landed in a lake near Chebarkul, a neighboring town
- 6,000 square feet of a roof at a zinc factory collapsed
- One local said it 'was like a scene from the Armageddon movie'
- Same day as Asteroid 2012 DA14, which is due to skim Earth's orbit tonight
ON Feb. 15, an asteroid designated 2012 DA14 will pass safely within about 17,200 miles of Earth’s surface — closer than the communication satellites that will be broadcasting the news of its arrival. The asteroid is about 150 feet in diameter and has a mass estimated at about 143,000 tons.
Should an object of that size hit Earth, it would cause a blast with the energy equivalent of about 2.4 million tons — or 2.4 megatons — of TNT explosives, more than 180 times the power of the atomic blast that leveled Hiroshima.
It seems everyday there is a new, and real danger to the very survival of the human race. It really is quite a balancing act, or a delicate dance, that keeps us all living on day after day. There are so many threats to one's existence it can become quite mind boggling. Even though the scientists say this potential catastrophe will miss us by a mere 15 minutes in time, there are millions more asteroids that sometimes are only discovered After they have passed us by, or with dangerously little time for a reaction.
Twenty five, fifty, or a hundred years ago, mankind never even gave such a thought to these threats from space, as if we did not have enough to contend with here as it is. And even today most still do not, as the day to day struggle for survival takes the proper seat at the front of the bus.
The last one of about this size to hit was on June 30, 1908, in a sparsely populated region of Siberia called Tunguska. The Tunguska blast released about four megatons of energy and leveled millions of trees across 825 square miles.
A much larger asteroid or comet, six miles in diameter, collided with Earth some 65 million years ago, which appeared to kill most of the large vertebrates, including the dinosaurs. Fortunately, Earth collisions with objects so big happen only at average intervals of 100 million years.
While no known asteroids or comets represent a worrisome impact threat now,NASA’s Jet Propulsion Laboratory shows more than two dozen asteroids have better than a one in a million chance of smacking into Earth within the next 100 years. That may sound reassuring, but we estimate that less than 10 percent of all near-Earth objects have been discovered. And while we are keeping a vigilant eye out for these objects in the Northern Hemisphere, we are considerably less watchful in the Southern Hemisphere.
a 50 meter asteroid passes this close every 40 years or so. It’s random, so the next one could be next week, or not for 100 years. That’s just an average over a long period of time.
The spooky part is that it is not a question of 'if' but 'when' will the Earth be struck again.
The Clay Center Observatory will have a live shot when the asteroid comes into view. Even a nice countdown clock to Earth avoiding yet another doomsday.
