Meteorite seen over eastern Spain
Wed Apr 13,10:09 AM ET
MADRID (AFP) - A meteorite which residents described as a "huge ball of fire" was spotted over the eastern Spanish regions of Catalonia and Valencia, according to astronomers in the region.
"We received scores of calls from witnesses, who at first thought it was an asteroid flashing past. But judging from its size it was a meteorite," said a spokesman for a Catalonia-based astronomers' association.
Motorists spotted the glowing sphere from the motorway linking Spain with southern France and reported seeing it break up into fragments.
The meteorite glowed a greenish hue as it sped through the atmosphere on a northeast-southeast trajectory.
"That leads us to think it fell into the sea," the spokesman said.
The observatory at Valencia University said it estimated the celestial body had been travelling at around 10,000 kilometres (6,500 miles) per hour when it entered the atmosphere.

Astrologer to sue NASA over comet plans
A Russian court has ruled that an astrologer can proceed with a lawsuit against the US National Aeronautics and Space Administration (NASA) for its plans to bombard a comet.
The astrologer claims the destruction of the comet would "disrupt the natural balance of the universe."
Marina Bai's case was thrown out of a lower court because Russia has no jurisdiction over NASA, but the ruling was overturned when her lawyer, Alexandra Molokhova, was able to show that the agency's office in the US Embassy in Moscow does fall under Russian jurisdiction.
Ms Bai seeks a ruling that will restrict NASA in its plans to annihilate a section of the Tempel 1 comet, in a project that has been dubbed Deep Impact, as well as punitive damages of $US300 million.
"My client believes that the NASA project infringes upon her spiritual and life values as well as the natural life of the cosmos and would disrupt the natural balance of forces in the universe," her lawyer said.
The lawyer says Tempel 1 has sentimental value to Ms Bai because her grandparents met when her grandfather pointed the comet out to his future wife.
In a $US279 million project, NASA in January launched the Deep Impact spacecraft.
It will travel to the comet and release an impactor - a 370-kilogram self-guided mass - on July 4, which is expected to create a crater that could be as large as a football stadium.
Scientists believe that the exposed material from the resulting crater will yield clues to the formation of the solar system and provide important information on altering the course of comets or asteroids on a collision course with earth.
Effects of the collision will be visible from earth with an amateur telescope.

This is all the info about (Nasa Deep Impact)
Thats at least what they want the public to know anyway...... :crazy:

This is one opinion:
Scenario 1. If the strength of the comet nucleus is weak the ejecta cone spreads outwards at an angle of around 45º-50º from the surface of the comet. The cone's base remains attached to the comet nucleus. The majority (roughly 75%) of the material will fall back down onto the surface of the comet, forming a large-diameter ejecta blanket. In this model, the crater may be as large as a football stadium (around 200 meters in diameter), and 30-50 meters deep.
Scenario 2. If the comet nucleus is rocky and strong the ejecta cone will be at a higher angle (around 60º). The cone's base will detach from the crater, and may detach from the comet entirely. Less material (around 50%) will fall back to the surface of the comet in this scenario, yielding a smaller ejecta blanket. In this model, the crater will be much smaller, on the order of 10 meters or less. The predictions of the volume of ejecta produced then differ by roughly a factor of 1000.
Scenario 3. If the comet material is porous then most of the impactor's energy and momentum are absorbed in the process of compression and heating. There is less energy available for excavation, which results in a much smaller diameter crater than expected. The crater will be deep, but produce a very small ejecta cone.

most likely it will be the type that breaks up into little peices and we'll get pummeled by them. either way, I just hope there isn't a "phantom" black hole near by because if it takes a whiff of all those gasses, it'll open up its vacuum and START SUCKING AIR BABY! Either way, July 4th this year is gonna be quite interesting!
I was just thinking that maybe NASA could ram a MAGNET inside of the Astroid instead of blowing it up and then launch some kind of a craft to attract it and it chases it out of our gravitational pull; dumb idea or?

Is this comet a threat or just a another science experiment?
May 8th, 2005, 9:33 PM
This comet (Templer1) isn't a direct threat however, we only have 60% of them mapped. Since they fly at 150,000 miles per hour they can emerge in a "New York" second. I like the fact that there are "astroid and comet" hunters. There are less than 30 of them. Its alot of work and tedius/painstaking hours at computers enlarging digital images. < DEEP IMPACT the July 4, 2005 event will be televised to some extent>. (I hope)

Ill will keep an up to date info on Deep Impact Project I really dont trust what Nasa is doing but who knows all may go well but you have got to look at both sidesssss.....
1)All goes as planned as 50% of the scientist are anticipating
2)All goes wrong and (Temple1) is broke into many fragments which earths gravity may grab a few chunks of it I personlly dont think it will be a doomsday event on our mother earth.....But you just cant never tell, the other 50 % of the scientist are very tense on this impact in fear of what may happen.....
Who really knows I guess July 4th 2005 we will know all what is to happen an yes I hope it is televised that would be veryyyy nice lol
Keep a check on this post cause as the date draws closer the more info I may be able to provide.
If anyone with new info, plzzzz post your thought and theories
May 9th, 2005, 5:43 PM
great! this event will be interesting to watch! I doubt that it will be a "doomsday" event as well. :prin:

This is another report I have found Concerning Nasa's Deep Impact Project
Dr. Michael A'Hearn, University of Maryland, Deep Impact Principal Investigator, plans to bring Humanity to the brink of extension. Billions of people will parish. In 2002, comets were discovered to be natural sources of antimatter. He knows comets are composed of antimatter but has lied to NASA by telling them that comets are made from dirty-ice. He is directing NASA's plans to slam a 370 kilogram spacecraft into the antimatter 9P/Tempel 1 comet on Monday, July 4, 2005. The 16,000 megatons of TNT explosion will blast the 140 million ton comet into trillions of pieces.
According to the Discovery Channel, "All the brightest and booming-est pyrotechnic shows on Earth combined couldn't for a nanosecond distract Mike A'Hearn from watching the Fourth of July ice works event that he's planning for the year 2005.
"On that day, while the rest of America oohs and aahs over rockets' red glare, the University of Maryland astronomer and professor will watch a comet traveling at 28,000 mph smash into an unmanned NASA spacecraft that's been hurtling toward its target for six months. The explosion should be spectacular."
The 100 micro-second explosion will be equivalent to 16,000 megatons of TNT, or enough energy to supply the entire World’s Energy needs one year.

Where is Tempel 1?
And where is the Deep Impact spacecraft?
Note: Make sure you have Java enabled on your browser to see the applet. (And please give it a moment to load!)
Orbit Viewer applet originally written and kindly provided by Osamu Ajiki (AstroArts),
and further modified by Ron Baalke (JPL).
If you'd like to check out the interactive orbital displays for other comets and asteroids, please visit the NEO Program.
Where do I look in the sky?
The above graphic is pretty cool, but how will it tell me where to look? The Deep Impact spacecraft itself will be too tiny and dim to see. A few observers were able to get pictures as it was leaving the vicinity of the Earth and Moon. Although you won't be able to see the spacecraft, you can try to find comet Tempel 1.
Be sure to take a look at Reading an Orbital Diagram to get some basic background on interpreting this graphic and what the sliders and other adjustments do.
So what happens to comet Tempel 1 in the future? Take a look at the orbital diagram for the comet and explore the scenarios!
Set the date for the middle of the month. Then adjust the sliders so that you are looking at the Solar System from overhead, that Earth is at the "bottom," and the zoom includes Jupiter.
For February, notice that Tempel 1 is roughly in the same direction as Jupiter and that if it were midnight in your location, you'd have to look towards the east to see them.
For March, notice that Tempel 1 is more in line with Jupiter when we look from overhead, but if we look from the sides, we see that because of the inclination of the comet's orbit, it's not perfectly in line. But, by the end of March and into early April, Tempel 1 is also almost in line with the Sun and Earth. The comet rises as the sun sets so it is visible all night.
For April, Tempel 1 is above the eastern horizon at sunset.
For May, Tempel 1 is on the meridian at sunset.
For June going into July, Tempel is just to the left of the sun so it is essentially in the western sky after sunset.
Below is a graphic generated in Starry Night Pro that presents the above result in a different way for the current month.
The above image is setup for 39° N latitude on the 15th of the month at about 10pm local time.
In other words, cities around the world at that latitude (Washington, DC; Springfield, IL; Denver, CO; Reno, NV; Lisbon, Portugal; Ankara, Turkey; Beijing, China) will see about the same thing at the given local time.
For other charts, look on the Star Charts page.

'Fireball' lights up sky
18/05/2005 15:09 - (SA)
Helsinki - An exceptionally bright "fireball" was spotted late on Tuesday slicing through the sky over Finland before exploding over the country's border with Russia, the Finnish Astronomical Association (URSA) said on Wednesday.
The phenomenon was witnessed by dozens of people in the eastern part of the country.
"Our mathematicians have roughly calculated that the (fireball) began its decent over our eastern border and ended in an explosion over the Russian Karelia region," URSA newsletter editor Marko Pekkola said.
Closer calculations will be needed to determine the exact route taken by the "fireball", which was probably an incandescent meteorite, Pekkola added.
