Tetra he was being sarcastic ,, he is just showing how silly for people think that their is a cover up when Nasa has images of the thing on website.

I believe there is a major divide within the NEO community on how to handle, not specifically this asteroid, but any future asteroid that is expected to impact earth. Just one piece of background hinting at this which I posted earlier…there are more.

Ex-Astronaut Says NASA Asteroid Report Flawed

It also appears as if the exact outcome of this event is still in the unknown category and government agencies tend to not be as forthcoming when they don’t know absolutes. There should have been more information on the demographically-related sites at a minimum.

Also, there have been one too many coincidences of electrical grid hacking, magnetic storms, etc. that could also be explained by earth/asteroid interaction in the news recently.

NASA is acting as an intermediary…a clearinghouse if you will on this. Because of their role, right or wrong…it limits the sources for news. Individual observatories are not giving press conferences on this…NASA is the go to agency for information. There has also been an unexplained deletion of information by Yahoo that is not their policy as referenced much earlier in this thread.

Lastly….and totally unsubstantiated gut feeling….if I were in someone’s shoes inside this knowledge loop…I would use this near-pass opportunity as a means to test whatever technology we have on the table to push, redirect or otherwise influence this asteroid’s path. If this asteroid isn’t the collision course asteroid, I would want to know that we had done a field test on the technology we will need someday. And, just in case there might not be agreement on what should be done in this area, such as a nuclear solution, I might not talk about it as freely. You may be right. I just don’t believe in coincidences…or government agencies always being forthright…I used to work within government types too – although not of the NASA level variety. I have indeed, danced with wolves. They like sheeples imho.

Your contributions to this thread have been amazing and I may be reading more into the lack of information than it's due. It just appears as if there are several long-standing differences of opinion within the NEO community that I wouldn't have even known about had we not had to dig so deep for information that wasn't more readily available.

Peace.

Yes, I was using sarcasm. To the extreme
For anyone tuning in, here it is again.

I've been told by a few others that there is a cover up, but yet, here we have the first radar images "hot off the dish".

I agree. Any "filtering" of news is a bad thing. It is always a bad thing when others make choices for the rest of us, be it news or politics or whatever. I never read movie reviews because I want to make my own decision on how good or bad a movie is.

But the really sad thing is that modern man has no stomach for any fear. Because fear has become something to totally avoid, Americans get the Patriot Act. As a whole, we want to be protected from cradle to grave. We want every possible device for protection in a car crash, instead of driving like our life depended on doing a good job.

Man has forgotten that life is risky, and he doesn't want to be reminded of it ever. And in his collective delusion that total safety can be attained, he is less safe every day. He is less safe because he hires politicians to "tickle his ears" with reassurance. He allows wars as long as the violence is somewhere besides his own doorstep. Horror movies are a sure winner because we know the blood is fake.

The filtering of news is just what most people want. Those that don't find places like ATS, and we're few in number, overall.

No problem DancedWithWolves, it is a good example to listen to both sides with something like this. I hope I've cleared up any worry people might've had with this thing, I've never seen anything like it, so many people were really scared by it.

I have no doubt at all that the media filters everything, but I think in this instance none of them really cared to pick it up and run with it, or else they'd be blamed for causing a panic or being alarmist.

It was not big news. So if Nasa is lying cover up etc etc and they also control the media could they not tell the media to inform the public this is another close pass asteroid like those in the past and like those it to will not threaten us?

Its really no biggy

[edit on 23-1-2008 by ncuncfan2006]


No they wouldn't..

Think about it.

Think what the people would do to them Physically for telling everyone there's no chance, and then it dose go ahead & hit us.

Their balls would be on a spit roast....lol

No. Because there wouldn't be any time to sling anyone's man-glands. The world would be in chaos, and George Bush and company will be the only one's to save us because only they "understand the threats we face."

This is the part i find frightening, The astronomy union has this weird review before they will issue a warning of an earth-impacting asteroid. Then it is up to the discoverers as whether they announce it to the public or not.

Is this a link to what you referenced?

Cambridge Conference Correspondence

Interesting, and disturbing.

Looks like, at a quick glance, they want to make sure their behinds are covered before they release any statements.

Let's see how long their site stays up now that you pointed us to it...



Edit to add: They don't like hot-linking or quotes...and also to rephrase to the interrogative...

I think some of you are overlooking a significant fact about all of this. If, repeat, IF this thing hits the Earth, by some odd chance, it will do only limited damage.

Yes, it's a pretty good sized hunk of rock, right now. But an entry would pare down that size by a good margin before it reached ground level. Even with the kinetic energy it would have, the total destructive area would be small in comparison to the overall size of the Earth.

I don't have the figures on hand, as I am sitting in a hospital waiting room and not at home, but lust figuring in my head it seems reasonable to assume that a land hit would devastate only about a ten square mile area. Secondary severe damage over a twenty square mile area, and minor damage over a fifty square mile area. And I expect that my guess is on the high side anyway.

Now I grant you this would be massive if it were downtown Chicago or London. But it would not be much worse than Mount St Helens. So on a world view, it would be another event of great note, but not something that would effect a significant portion of the population directly.

A water strike would be a lot worse naturally, because of the "tidal wave" it could cause. The effect would be harder to figure as direction and distance to the nearest land would be important factors. But many nuclear explosions have been made at sea during tests of various bombs, and few of them resulted in any real impact to the overall world coastlines.

All I'm saying is that this should be kept in some perspective, even if you insist on worrying about this rock after being assured that any impact appears to be a long shot. Even if this thing struck Earth, I would think that any one person here being directly effected by it would be about the same as winning the lottery.

ArMaP mentioned somewhere back on an earlier page that, should this strike land, the concussion could break windows at a 100 km.

Here's his post:

According to the Earth Impact Effects Program, a rock of that size would make some serious damage. Not on a global scale, but at a distace of 100km it would be strong enough to break glass windows.



Your Inputs:
Distance from Impact: 10.00 km = 6.21 miles
Projectile Diameter: 300.00 m = 984.00 ft = 0.19 miles
Projectile Density: 3000 kg/m3
Impact Velocity: 17.00 km/s = 10.56 miles/s
Impact Angle: 45 degrees
Target Density: 2500 kg/m3
Target Type: Sedimentary Rock

Energy:
Energy before atmospheric entry: 6.13 x 1018 Joules = 1.46 x 103 MegaTons TNT
The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 3.0 x 104years
Atmospheric Entry: The projectile begins to breakup at an altitude of 54000 meters = 177000 ft
The projectile reaches the ground in a broken condition. The mass of projectile strikes the surface at velocity 16.1 km/s = 10 miles/s
The impact energy is 5.53 x 1018 Joules = 1.32 x 103MegaTons.
The broken projectile fragments strike the ground in an ellipse of dimension 0.904 km by 0.639 km

Crater Dimensions:
Crater shape is normal in spite of atmospheric crushing; fragments are not significantly dispersed.
Transient Crater Diameter: 4.04 km = 2.51 miles
Transient Crater Depth: 1.43 km = 0.888 miles
Final Crater Diameter: 4.88 km = 3.03 miles
Final Crater Depth: 0.477 km = 0.296 miles
The crater formed is a complex crater.
The volume of the target melted or vaporized is 0.0348 km3 = 0.00835 miles3
Roughly half the melt remains in the crater , where its average thickness is 2.71 meters = 8.89 feet

Thermal Radiation:
Time for maximum radiation: 0.219 seconds after impact
Visible fireball radius: 2.75 km = 1.71 miles
The fireball appears 6.25 times larger than the sun
Thermal Exposure: 1.90 x 105 Joules/m2
Duration of Irradiation: 46 seconds
Radiant flux (relative to the sun): 4.13

Seismic Effects:
The major seismic shaking will arrive at approximately 20 seconds.
Richter Scale Magnitude: 6.7
Mercalli Scale Intensity at a distance of 100 km:

VI. Felt by all, many frightened. Some heavy furniture moved; a few instances of fallen plaster. Damage slight.

VII. Damage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built or badly designed structures; some chimneys broken.

Ejecta:
The ejecta will arrive approximately 144 seconds after the impact.
At your position the ejecta arrives in scattered fragments
Average Ejecta Thickness: 2.39 mm = 0.094 inches
Mean Fragment Diameter: 3.01 cm = 1.19 inches

Air Blast:
The air blast will arrive at approximately 303 seconds.
Peak Overpressure: 10000 Pa = 0.1 bars = 1.42 psi
Max wind velocity: 22.6 m/s = 50.6 mph
Sound Intensity: 80 dB (Loud as heavy traffic)
Damage Description:
Glass windows will shatter.

Asteroid to give Earth a close shave next week


Agence France-Presse
First Posted 21:47:00 01/23/2008

PARIS -- A huge asteroid will zoom past Earth next week at such a close distance that amateur astronomers should be able to spot it, specialists said on Wednesday.

Measuring between 150 and 600 meters across, asteroid 2007 TU24 would inflict devastating regional damage were it to hit Earth, but there is no risk of any collision, they said.

It will fly by on Tuesday, being around 534,000 kilometers (334,000 miles) from the Earth at its closest point at 0834 GMT, according to a Near Earth Object (NEO) database compiled by the University of Pisa in Italy.

"For a brief time the asteroid will be observable in dark and clear skies with amateur telescopes of three inches (7.5 centimeters) or larger," NASA said on its NEO site.

2007 TU24 will make the closest approach of any known potentially hazardous asteroid of this size or larger until 2027, NASA said, adding that objects of this size come close to Earth about every five years or so on average.

The rock was discovered only last October under a surveillance program run by the University of Arizona.

According to the Minor Planet Center of the Paris-based International Astronomical Union (IAU), the closest detected approach by an asteroid was on March 31, 2004 by 2004 FU162, which came within 6,500 kilometers (4,000 miles) of Earth.

The day after 2007 TU24's terrestrial flyby, asteroid 2007 WD5 is expected to come within 26,000 kilometers (16,250 miles) of Mars, a distance that is less than a whisker in space terms.

2007 WD5 ignited a brief surge of excitement among astronomers after it was discovered in November.

Initial computations of its orbit gave a roughly 1-in-25 chance that it might whack into Mars on January 30, providing a celestial show that could be monitored by US and European scoutcraft there.

Measuring about 50 meters (165 feet) across, it would have delivered an impact equivalent to a three-megaton nuclear weapon. A rock of this size exploded over Tunguska, Siberia, in 1908, felling around 80 million trees over 2,200 square kilometers (850 square miles).

But further calculation showed that the hoped-for big splat would be a big miss.

"It's highly unlikely that it's going to hit," said NEO expert Benny Peiser of Liverpool John Moores University in northwestern England, as the odds of a collision by 2007 WD5 fell to around 0.01 percent, or one in 10,000.

Not to keep repeating myself but,

Cause of death Chances

Motor vehicle accident 1 in 100
Homicide 1 in 300
Melanoma (a skin cancer*) 1 in 300
Fire 1 in 800
Firearms accident 1 in 2,500
Electrocution 1 in 5,000
Asteroid/comet impact 1 in 20,000
Passenger aircraft crash 1 in 20,000
Flood 1 in 30,000
Tornado 1 in 60,000
Venomous bite or sting 1 in 100,000
Food poisioning by botulism 1 in 3 million

And we have tornado drills all the time. But again, nothing to worry about.

Given that noone has died from asteroid or comet impact that I'm aware of, like in a long long time, wouldn't it be more like 1 in 5 billion? 1 in 20000 would seem to be factoring in a guaranteed hit.

Also, according to the nasa site (ssd.jpl.nasa.gov...), at Earth MOID = .0012501 AU (187,515kms) it is passing 65% closer than indicated in this article, and by my calculation was closest at around Midnight GMT, 29 Jan, though i could be wrong of course.
