AN ASTEROID exploded over Indonesia with the force of three Hiroshima nuclear bombs - and no one on Earth knew it was coming.
The New Scientist website reports the dramatic explosion over South Sulawesi, Indonesia, on October 8 underscores how blind humanity is to the danger of giant space rocks.
Scary.
Well it is a BIG ASS SKY. what do you expect? can't possibly watch it all with the spending going to other areas that is deemed to be more important...

Oh good Christ...wah wah wah. Even WITH the cash, you can't watch the entire sky.
I've pretty much always thought if it isn't a nuclear bomb, then it's going to be an asteroid. Can't win!
1.3
AT what point did I say we could watch the whole DAMN sky? Oh yeah I DIDN"T! Stop the ASSUMING. read the post for what it says nothing more or less
WAH WAH WAH childish
Interesting seed. Clipped to Odd News Group.
Ok, so a high altitude explosion but still... imagine if that had been over Los Angeles. Imagine if it had been lower.
It's difficult to visualize exactly how nasty this could be but there are some really simple google maps mashups that do a pretty good job of drawing unpleasant looking circles to give you an idea.
OK Lets stop this right here, lets no imagine it, 90 per cent of things we worry about never happen, thats never. If a big rock is coming then dont worry about it, let the Yankess use Arod to catch it and we are all safe, end of story. Now go back to your worrying about something else useless

Now I'm not a worry-wort but 2 nights ago I had the scariest dream dealing with this very issue. I even wrote about it and posted it here on the vine. "What really matters. What would you do?" Just to get it off my chest. Believe me it's better that it explodes in space than to have an impact in a populated area. After that dream I'll happily read about explosions in space over having an extinction level event.
"Now go back to your worrying about something else useless"
Do you support the War on Terror? If so, I find your attitude ironic...
Thanks for the laugh, Boons!
Nah, we shouldn't worry about asteroids any more than we should worry about Bin Laden hiding under our childrens' beds.
All the same, sometimes bad things happen.
Now if you'll excuse me, I have to go find my flashlight - it's dark under my childrens' beds.
Screamingeagle...Yes I know I said I'm an Atheist but you applied that portion of my comment to your posting trying to make the villain here. What I meant and YOU know it!,is how OTHER people would view it! Not ME! I was only trying to look at this from a believers point of view and being fair about it but you could not or would not recognize what I REALLY meant. And Killfile your reply 2.9 was way off point, I watch what most people watch in the news, I'm getting the SAME info YOU are getting so don't assume I am seeing what I want! I see what YOU see so don't high hand me and minimize what is really going on here. You should work for the Repubs. since you have shown yourself so adept at spinning to make me look uncaring and yourself so benign. You should know from my past postings how much I speak about peace and want it to be so, so your spinning of my comments are disingenuous and self serving.
Good catch Kill.
It's just a matter of time before another Tuskunga sized event (1908). If that asteroid explosion had happened three hours later, goodby London. That event was about 10 megatons, 1,000 times bigger than Hiroshima.
To me it's the "three hours" part that really boggles my mind. We really have so little appreciation for how fast this top we live on in spinning and flying through space. Shift the time of impact just a little and "the middle of nowhere" becomes "Manhattan" or Rio, or Mexico City.
When you step back and look at the numbers its terrifyingly random and capricious.

Yeppers! Here is a link to a foundation that wants to do something about this.
http://www.b612foundation.org/
A good friend of mine is Brian Marsden, who just retired from the Minor Planet Center. After the asteroid scares of about 15 years ago, we started calling him "Dr. Death". He got a kick out of it.
Yes, another great catch, Kill.
Good seed, if this story doesn't scare the livin $#&! out of you, I don't know what will.
Here is a news video from Indonesia on the subject.

a giant meteor would be pretty quick and painless (right?).. on the other hand.. THIS does scare the living crap outta me! imagine going to sleep in your nice comfy bed and then waking with a damn car on top of you!
killfile, good seed!
on October 8 underscores how blind humanity is to the danger of giant space rocks.
And what are we supposed to do about them then? Do we have missile defense systems to blow the rocks away? A rock is coming, what exactly are humans supposed to do?
Well, the earlier we know something the more we can do. Distances in astronomy are... well... astronomical. Even if one of these city-sized rocks is hurtling at us at a dozen times the speed of sound, we could theoretically spot it a few years out (if we took the time and energy to look).
Well... a few years out means you don't have to hit it all that hard... just push on it slightly for a long time. Think of driving an asteroid as being like driving a car. If you see that you're headed towards a tree that's a mile down the road you barely have to nudge the steering wheel to avoid it. If you happen to notice the tree when it's 10 feet away and your headed towards it at 70mph, however, there's not a lot you can do.
The same thing is true of space rocks. Divert something from a collision course early enough and you scarcely have to nudge it. Wait until it's right on top of you, however, and you're pretty well screwed.
Um yeah but comparing something that is in the solar system, and not on earth such as trees and cars doesn't really work all that well.
You are basically trying to say let's move Earth out of the asteroid path. If you can do that, heck go for it.
We're constantly under threat and scientists have predicted so many different years from 2014 all the way up to 2880.
We're supposedly going to have a collision March 14, 2014 by 2003 QQ47, which was discovered in August 24, 2003. 2002 NT7 was supposed to hit in 2019, but that has been cleared.
Actually, we don’t have to push it sideways enough to avoid Earth’s orbit. All we really have to do is speed up or slow down one of the two objects- Earth or the asteroid. Since we obviously do not want to alter Earth’s orbit around the sun, and because Earth will be orders of magnitude larger, we’d chose to alter the asteroid’s speed. If we sped up or slowed down the asteroid, its trajectory may still intersect Earth’s orbit. However, it will do so when the Earth is at a different location in its orbit, and thus avoid collision. I suppose either method would work though! Of course then we'd have to figure out a way to attach literally thousands of rockets to a planetary body, moving millions of miles per hour, and take into consideration of shifts in gravity, the speed of both objects and hope nothing goes wrong along the way..which is improbable. As Kshark pointed out, the trjectory of the planetary body would constantly be changing so predicting it's [ath would be "iffy" But I'm sure we'd try!
spot it a few years out (if we took the time and energy to look).
And money --
"A survey that finds all of the 20-metre objects will cost probably multiple billions of dollars."
"If you want to find the smallest objects you have to build more, larger telescopes.
I can't even imagine how difficult it is to spot an asteroid in the solar system.
It would be like trying find a spare key that might exist in a house as big the pacific ocean.
Hell, I can't find my keys have the time in my house as it is...even when they are in front of my face.
You are basically trying to say let's move Earth out of the asteroid path. If you can do that, heck go for it.
No, we are not.
I can't even imagine how difficult it is to spot an asteroid in the solar system.
We do it all the time. Google LINEAR telescope, the "Minor Planet Center" to get more information.

Oh, I know we find asteroid all the time. I find my kids toys laying on the floor that they never seem to see.
However, I am saying in the vastness of space, do we know what we are not finding?
We can't search the whole universe but it takes a long long time for stuff to fall in from even the Asteroid Belt. It's within our capabilities to at least look for the really huge rocks w/in the solar system.
I don't mean "20 meters" here. I'm talking about the sort of rocks that generate extinction level events.
Killfile--
Well if you have the money to roll out as clearly no one else does, and since we have a crap load more problems on earth, so I appoint you to fund and pay for and build whatever is possible to find and blast away asteroids.

LOL We would have a LOT more problems than just an asteroid.

Ah well might as well start talking about all of this now and put everyone in true panic mode and paranoia.
"Don't wanna close my eyyyeess...Don't wanna fall asleeepp!"
All we need are Ben Affleck and Bruce Willis in a rocket and some dynamite.
i think a missile command style asteroid shooting system would be great, and then let it rip on the intertubes so the willfully unemployed gamers can utilize their skill set and save the planet... shave the planet, yesh?
or a diamondillium shield, or was it diamondonium...?

Unobtainium
Apparently, the element upsidasium falls upward away from Earth whenever it is mined. I say we mine all we can and make warheads we can shoot at these meteorites. It will also be a boon the the economy of Frostbite Falls.
sorry, multiple futurama references with a bit o' final fantasy x thrown in to boot... ; )
A 45 to 50 kiloton explosion. People won't really pay attention unless we have another Tunguska-type event within 100 miles of a major city. How many megatons was that again?
So realistically, how BIG, how heavy was this "asteroid?"
Exploding with a claimed 50 Kilotons comparable energy, that would make it 2.0 to 2.5 times the explosive power of the Hiroshima bomb.
That nothing on the ground was damaged because the burst was 20 kilometers up is good, of course. But nevertheless surprising, that there was no damage below. Considering what the Tunguska explosion wreaked nearly a century earlier.
So what or whom are we expected to blame for the asteroid not being spotted? What should we have done to avert it, one might ask? I would guess exploding a nuke against it, a few hundred miles out in space being a "no-no.
http://neat.jpl.nasa.gov/
"Potentially Hazardous asteroids (PHAs) are larger than ~0.2 km (0.1 mile) and approach close enough to present a potential hazard but not a current hazard. "
So that was much smaller than they consider hazardous, by my reading.
http://neo.jpl.nasa.gov/programs/
"In 1998 NASA commenced its part of the "Spaceguard" effort, with the goal of discovering and tracking over 90% of the near-Earth objects larger than one kilometer by the end of 2008."
Asteroid False Alarm Shows Limits of Alert Systems- March 8, 2004
The scare was the latest in a series of false alarms that highlights the apparent lack of procedure for dealing with a possible asteroid threat. Several astronomers complained they did not know whom to call in an emergency.
Last Tuesday, Lindley Johnson, a program scientist at NASA's Near-Earth Object Observation Program in Washington, D.C., sent a memo to a select group of asteroid experts. Should a potential impactor be detected, Johnson wrote, "You call me."
Very well. But what happens next? There is no government agency assigned to "protect the Earth." In theory, if Johnson's office is warned of an asteroid threat, the office would pass it along the chain of command to the NASA administrator, who would contact the President.
Asteroid "Near" Miss: False Alarm or Wake Up Call?
...
Let me paraphrase a leading astronomical group's position paper on the potential threat of an asteroid impact: What greater feat could there be than to perhaps someday alter the course of an asteroid to prevent an impending disaster? And what greater tragedy, given our knowledge and abilities, than to be caught unprepared?
So that was much smaller than they consider hazardous, by my reading.
Just remember that the big hole in Arizona (meteor crater), was caused by an object 28-32 meters in diameter.
The PHA designation is for one that will wipe out civilization. One the size that hit arizona would make for a very bad day in any city of the world.
Google the "Torino Scale" for asteroid impactors.
Thanks space_guy
This says 50 meters, but either way that's still much smaller than 0.1 mile, so your point remains.
http://www.americansouthwest.net/arizona/meteor_crater/index.html
Current theories place the size of the meteor as 150 feet in diameter, and its weight at 300,000 tons.
Cletus
The size keeps changing all the time. I am going on what the folks that model the impacts tell me. Google "Jay Melosh, Meteor Crater, or Elizabetta Pizzario" as they did a study on the impact and have more recent data.
It doesn't matter in this discussion, it's down in the noise.
Excellent example.
I watch the evening news everynight and I've never even heard of this story. Weird.
That's because it isn't a human interest story. I imagine there are other reasons as well--such as the fact that it was Indonesia and not New York City. And don't forget that the mainstream media stay away from any story that can't be done "in depth" in about thirty seconds. Just witness all the confusion above over what could be done to divert an asteroid. What! You mean we don't have to wait until the asteroid has a magnificent view of the Earth before we send Bruce Willis and company there to blow the beejeezuz out of it?! Probably when an impending asteroid is newsworthy, we'll be hearing about it from the bottom of five-mile crater rapidly filling up with a tsunami.
Well said! Too funny.
Is this a real, factual, verified story?
As it turns out, yes it is:
NASA: Asteroid Impactor Reported over Indonesia
October 23, 2009
This is some scary stuff.
On October 8, 2009 about 03:00 Greenwich time, an atmospheric fireball blast was observed and recorded over an island region of Indonesia. The blast is thought to be due to the atmospheric entry of a small asteroid about 10 meters in diameter that, due to atmospheric pressure, detonated in the atmosphere with an energy of about 50 kilotons (the equivalent of 100,000 pounds of TNT explosives).
The blast was recorded visually and reported upon by local media representatives. See the YouTube video at:
http://www.youtube.com/watch?v=yeQBzTkJNhs&videos=jkRJgbXY-90
Indeed scary, but even if they knew a asteroid was going to hit(especialy a very large asteroid that could seriously damage the planet) do you think they would inform the public or just deal with the problem afterwards rather then deal with public hysteria also?
Jim: If a really big one were to hit us I'm afraied there would be no way to deal with it afterwards, unless you would classify starting civilization over from scratch as dealing with it. UFOs stand by we may need you.
Would you want to know if It was going to hit? I know I would, Id rather spend my last days with my friends and family then shopping or working.
It may be terrifying but there is nothing we can do about these little rock bombs. And the Earth has been absorbing them for billions of years.
Maybe God threw a rock at us to wake us up and get us to act a little more decent toward each other. Trouble with God is he (she) never just sends a note.
It may be terrifying but there is nothing we can do about these little rock bombs. And the Earth has been absorbing them for billions of years.
Of course there is something that we can do. We have the technology to deflect all but the very largest impactors today, we just are not spending the money to get ready.
Maybe everbody accidentaly deleted God's (him or her) e-mail because everbody thought it was spam or some scam. Who knows?
Ah, there was a note tied to the rock God threw at us.
We would have been able to read it before it disintegrated if only we had bothered to develop a telescope that would have seen it.
Our bad.
Isn't 3 years to early, 2012 and all that stuff definitely a brown trouser day.
A Killfile story that doesn't invoke race baiting or demonizing Republicans with agenda driven links? This is a real treat.
Asteroid my ass................
run , run and fill the Churches , ask for forgiveness for being
so shelfisassdognestylowmotherfucional.
kiss your dog because you value more the life of an animal than a human life
get IN your knees and garb the ground and ask for forgiveness for so many destruction in the name of progress and greatness
You know, Atari has been preaching the dangers of these space projectiles since 1979, and no one has heeded the warnings.
It's our own damn fault if we get blasted.
Could we blame WTC, GWB or should we blame BHO?
Seriously, I'd expect smallish objects like this would be hard to spot photographically. Radar might or might not pick them up far enough out to make deflection feasible. A larger asteroid, the kind that would devastate a continent, would naturally be brighter and more likely to be discovered in time to make a deflection attempt feasible.
But these smaller bolides rarely survive to reach ground. I'd suspect most will break up high enough to leave only small fragments reaching the ground. Also, and this IS a big plus for us. . . the majority of our planet is covered with water (good old H2O). Sort of stacking the odds in our favor. . . respective to a no-damage impact.
The story is interesting. . . but hardly worth getting alarmed over. Given there was, from anything I've heard or read, NO DAMAGE, WHATSOEVER at ground level. Like no impact damage. No massive fires started. Certainly no radiation like you'd have gotten from a nuclear blast that high up. So really, other than evoking unnecessary alarm in gullible people, what's the point of the tag line: "nobody saw it coming" if not to get people to dump on NASA and the government?
Could this have been a missile test from N.Korea? Where are the conspiracy theorists when you really need them?
Not scary at all. If and when it happens, I could only hope that it is quick and total.
