Was the Russian meteor expected and the info NOT released?

[rdunk]

An ice meteor (or a comet) would explode without leaving an impact crater or debris.

And why do they explode, as opposed to just burning up? Does ice explode, just because it is hot? A rock? What is the history on such explosions?

[ArMaP]

OK

Please explain this:

What part of "reflections on the windshield" didn't you understand?

[ArMaP]

Well of course, it could explode forward............as long as the explosive force was greater than the forces reacting against its forward progress.

That's why they call it "explosion", because the release of a large amount of energy is done in an extremely short amount of time.

But exactly what would it be that might cause such an explosion "naturally"?? I have watched a lot of "incomings", but have never seen one actually explode!

I think it's the difference in temperature between the centre and the outer "shell", the one that is burning in the atmosphere, added to the aerodynamic forces acting upon that outer "shell".

You think? Can't we do better than that?

Why do meteors explode?

Asteroids are just chunks of rock, so what makes them so explosive? In a word: speed.

The kinetic energy, or energy of motion, of a speeding asteroid is enormous. The Russian meteor entered the atmosphere going 40,000 miles per hour (64,374 km per hour), Bill Cooke, lead for the Meteoroid Environments Office at NASAs Marshall Space Flight Center in Huntsville, Ala. said in a NASA press briefing.

The chunk of asteroid or comet that caused the 1908 Tunguska event is estimated to have entered the atmosphere at about 33,500 mph (53,913 km/h).

The shock wave from an asteroid's interaction with the atmosphere heats up the rock, essentially vaporizing it, Boslough said. The hot vapor then rapidly expands in the atmosphere, with explosive results.

"It's just like TNT going off, only much more energy," Boslough said.

All the stuff I blew up was always cold on the outside and hot on the inside.
That must be unobtainian gas trapped inside those rocks.
if they store that much energy.we should put it in rocket ships.
A shockwave is not an explosion.an explosion does have a shockwave.

I think tptb want us to think meteors explode.
The kenetic energy was released in the shockwave.
The shockwave is at right angle to direction of object.
the forward momentom is carried in the shockwave by moving forward and out.
all forward momentom of air molecules exceeding the speed of sound
are slowed to below the speed of sound.

[robomont]

By the time the debri gets to us it is usually traveling 130mph.
just strong enough to punch through a house or car but no crater.


Now if haarp burns a hole in the atmosphere ahead of the meteor.
all bets are off.
its like laying track ahead of a freight train.

And why do they explode, as opposed to just burning up?

Trapped air and gases in the rock, frozen in space. Heat up instantly, expand and KABOOM. Leave a sealed can of soda in your car in Vegas in the summer... same effect... and one sticky mess

Does ice explode, just because it is hot? A rock?

Yes even metal

What part of "reflections on the windshield" didn't you understand?

the "reflections on the windshield" part

Hmmmm well....

Huge Chunks of Ice Fall From The Sky








Ummm so... you were saying?

[robomont]

Z,I have to disagree that ice flashes or water flashes from meteors.
I believe the expansion of the steam would be at a slower rate due to the insulating factor of the rock and its density as far as being one bonded unit at entry into the atmosphere.

As the pockets of water are exposed to heat they turn into steam jets that cut along the outside of the rock.sometimes cutting the rock into smaller pieces.
these rocks all put off sonic booms fractions of a second apart causing a long boom instead of a single boom.this causes the rock pieces to spread out similar to an explosion.
 

As far as ice is concerned.ice would make a boom on entry too.otherwise it is a hail stone or ice from a plane.
Imagine the strongest wind one can.
then imagine how big a hailstone that wind could hold up in the atmosphere .hail stones the size of a fridge?

Ummm so... you were saying?

Was it a meteor or a comet? That's what I was talking about, not generic "chunks of ice".

Russian scientists confirm meteorite fragments found

http://www.cbc.ca/news/world/story/2013/02/18/meteor.html

The meteor entered the Earth's atmosphere at a hypersonic speed of at least 54,000 km/h, the Russian Academy of Sciences said in a statement.

Ok so this thing was moving at mach 44 approximately.

So missiles travel at Mach 4 approximately.

Math doesn't work for it to be a earth bound missile.

Any chance or ET friends were helping out?

The Truth Is They Do Have The Satellites That Moniter NEO's

(some of us know this, yet its hard to prove)

Thanks to this little crack in the armour.


The DOD manages the information,
and does not share it with scientists, according to this statement.

"The satellites that monitor the skies around the world for missile launches also detect brilliant incoming meteoroids, including startling events much smaller than the Chelyabinsk bolide," said asteroid expert, Clark Chapman of the Southwest Research Institute in Boulder, Colorado.

This type of information is extremely valuable for helping scientists understand the potentially dangerous cosmic environment of planet Earth, Chapman told SPACE.com. [See video of the Russian meteor explosion]

"In the past, these data have been partly withheld from the scientific community. They should be released immediately, while scientists, emergency management officials, and others are trying to understand what has happened, where people might have been hurt, and where valuable meteorites might befound," Chapman emphasized. p/quote]

Military higher-ups and the agencies involved are guarded about how potent their satellite sensors are as they stare at Earth for nuclear detonations, missile launches and the like.

In a new exclusive interview with SPACE.com, U.S. Air Force Brigadier General Robert Rego, who is in charge of the policy guidance behind the data release, said the Air Force Space Command is "circling the wagons" to close some loopholes in the dissemination of potentially sensitive information.
