Skip to comments.Astronauts to reveal sobering data on asteroid impacts
Posted on 04/20/2014 7:56:31 AM PDT by upchuck
This Earth Day, Tuesday, April 22, three former NASA astronauts will present new evidence that our planet has experienced many more large-scale asteroid impacts over the past decade than previously thought
three to ten times more, in fact. A new visualization of data from a nuclear weapons warning network, to be unveiled by B612 Foundation CEO Ed Lu during the evening event at Seattle's Museum of Flight, shows that "the only thing preventing a catastrophe from a 'city-killer' sized asteroid is blind luck."
Happy Easter - HE is risen!
Can rabbis stop meteorites from hitting the Earth? You bet your asteroids they can!
How did we not notice “several large scale asteroid impacts” over the past decade? Did they all hit in the border area between the US and Mexico? That seems to be the only place in the world that the US government can’t see.
I’m so sick of “sky is falling” science that is only designed to gather grant money.
On Earth Day? Well that can only mean one thing. The solution is a global socialist command economy. We are all going to have to "do our part." There will be rationing and bans on common items and vilification of the American way of life. You can't argue with the science. This is much too important and we only have ten years to give the smart people full control of every aspect of human behavior. Is it really too much to ask?
Probably means that global warming is causing the atmosphere to thin out and the result is less friction on incoming asteroids so they are reaching the ground. I cannot wait for this theory to emerge.
Meanwhile, in the past decade the only major ASS-teroid that has hit the US is in the white house.
Global warming causes falling space rocks!
That's at least 80% of potential impact area with almost nobody around to see an asteroid hit.
“the only thing preventing a catastrophe from a ‘city-killer’ sized asteroid is blind luck.”
Well, at least we got that going for us.
I suggest that we build a dome of money over Democrat-dense cities, to be built by obamateur’s cronies and his union buddies. It won’t do a thing to deflect an incoming asteroid but it will divert money into the appropriate hands.
Seriously, for all the alarmist blather, when was the last time in human history that an asteroid wiped out a city on earth?
We need to build a giant shield to cocoon the Earth from the danger of asteroids. Taxes will have to be raised globally and the money deposited into a UN account to build the shield.
>>I’m not so sure. 70% of Earth surface is ocean. Figure perhaps half of what remains as almost uninhabited: Siberia, northern Canada, Mongolia, Antarctica, Amazon, Sahara, Saudi, etc.
That’s at least 80% of potential impact area with almost nobody around to see an asteroid hit.
I’d agree if they were just claiming that we get hit with more space debris than we thought. But, they are talking about large-scale impacts. You don’t have to see those to know they happened. A lot of that ocean is heavily travelled by ship and aircraft. Are they calling a football-sized rock large-scale??
It’s all for the good of the collective, EGD. Now be a good little prole and go eat your sustainable twigs and grass.
I’m more likely to have a “widow maker” hit me while I am working in the woods than an asteroid and global warming hasn’t a thing to do with it.
Thus the reason God doesn’t allow us to know when our final day will be. He wants us to live every day as if it were our last with no cramming on the righteousness test.
This is a real threat as compared to the phony threat of global warming
Don’t know. Article was pretty vague.
Actually, ocean routes are about as well defined as roads on land. Almost everybody takes the shortest route between two points, so the VAST majority of the ocean is seldom-traversed.
If we get hit by 3x to 10x the space debris we thought, then wouldn’t we also have 3x to 10x the large scale impacts?
Heavy wet snow falling.
Tree about 2' thru at base suddenly fell across the trail about 50 feet behind me.
Surprisingly, it DID make a sound!
Setting up the excuse for when a terrorist nuke goes off?
>>If we get hit by 3x to 10x the space debris we thought, then wouldnt we also have 3x to 10x the large scale impacts?
True. How many large-scale impacts have we actually seen in the last 20 years? I’m talking ones that would have done major destruction to a city if it had hit one?
10 x 0 = ???
Just put up a big sign: Asteriod Free Zone.
This will remain a non issue until the left wing press figures out how to blame asteroids on global warming, the Republicans, the NRA or capitalism. Today, the news isn’t just ‘spun’; events are simply the means to support political propaganda. The ‘spin’ has become the news.
So that’s what happened to Detroit. It wasn’t democRat rule after all.
Burt Rutan has stated, nevermind Global Warming, where is a Space response ( i.e rockets w/ warheads(?) ) to this threat which as he noted a greater threat than the canard of man made global warming ( Oh that was not an intended pun, but canard / Rutan LOL!, a joke only airplane nerds would get )...
The past decade? And nobody noticed these impacts?
I think a larger span of time was meant but not properly stated.
Well they (city killer+ size) havent hit anywhere on land because that would result in a nuclear winter style scenario and they have not hit in water because that would result in monster tsunamis.
So where did they hit? Did they bullseye Krakatoa and no one Noticed?
To determine the likelihood of that happening, you’d first have to determine what percentage of the world’s surface is urban.
One number I’ve seen is 3%. Don’t know the definition they used.
It means any asteroid that hits the earth has a 1 in 33 chance of hitting a city.
I think it means the statists see the writing on the wall for global warming. Time to crank up another world-ending catastrophe. Another one that only the elitists can save us from, and only if we turn over to them all our money and liberty.
They are smarter this time and they will make the supposed catastrophe so nebulous and so far in the future that their "science" can never be disproved. The end will always be just around the corner if we don't submit.
Sodom and Gomorrah?
Seems to me that it logically follows that asteroids should get smaller and smaller over time. The larger they are the more gravitational pull they have and the more likely it becomes that they’ve already fallen into the sun or been collected already by a planet or moon. There aren’t any more being made out there, so the mean size should be falling all the time.
Well, depending on 'open minds'...
Sodom & Gomorrah
I guess 'Dodom & Comorrah', et al, must be either lucky or something, huh? /s
>>So where did they hit? Did they bullseye Krakatoa and no one Noticed?
The people that are using this to waste grant money said decades. In the last century, I can only significant impact that I can think of is Tunguska, and that more than a century ago.
Never ceases to amaze me how gullible people can be. And how willing to waste money. Sure it can happen, but to lie at the level they are about it is obscene.

I’ve wondered for a while if “rogue waves” (those giant suckers in the middle of the ocean) might have been produced by large impacts...
The article showed a photo of the recent meteor falling in Russia, which never hit the surface, so I’m thinking these strikes they’re referencing were all atmosphere impacts.
To produce a city-killer impact, say 20KT like the Hiroshima bomb, takes impact by a stony asteroid about 8 meters.
Unfortunately, an asteroid of that size usually fragments and vaporizes in upper atmo, producing something around 5 KT, with zero blast damage at ground level. Buildings and people might be destroyed by fragments.
Here is a truly cool calculator you can use to play around with what happens when an object impacts.
Big ones do unbelievable damage. But then big ones don’t come along very often, even on a geological time scale.
The moon has been a significant deterrent to asteroids.
>>The article showed a photo of the recent meteor falling in Russia, which never hit the surface, so Im thinking these strikes theyre referencing were all atmosphere impacts.
I agree. And I think that this is the kind of stuff that makes scientists seem more like carnival barkers than legitimate scientists.
They didn't even notice where a large airliner went to which was packed with nearly 250 people, with all the latest tracking technology.
BTW we've had several NEO's in the past decades and never saw them until they passed us.
If you want a city-killing impact it’s unfortunate.
Inhabitants of the city in question are likely to have a different opinion.
>>BTW we’ve had several NEO’s in the past decades and never saw them until they passed us.
Those are not impacts. You don’t get as much grant money by studying misses. You get more money by claiming that the sky is falling, has already fallen and people didn’t know it, and that it will fall more often in the future.
Scientists should not be carnival barkers.
Correct, near earth objects (NEO's) are certainly not impacts.
My point was if we have difficulty tracking or even detecting them until after they pass the earth, then the chances of detecting every one impacting the earth, especially ocean impacts, would seem unlikely.
Same point regarding the Malaysian airliner which they couldn't even determine where it went to, and it was packed with nearly 250 people, with all the latest tracking technology.

Airplanes don’t strike the earth with the force of an atomic bomb.
Go back and read the OP instead of trying to punch a hole in my statements. I’m not saying that meteors don’t exist or that they can’t hit earth. I’m talking about the prostitution of science as a means of stealing from taxpayers.
I never suggested or implied they did.
There are lots of people who have made incredible discoveries and contributions (amateur astronomers) who were not paid a dime.
BTW other than possible funding issues, what part of this article/study is science prostitution?
Raising taxes and putting the UN in charge is hardly a sane idea. IMHO.
Don’t confuse radar tracking capabilities with our ability to detect explosions through the nuclear detection network.
