Inside the comet impact the disclosure may watch the scene a number of ways.
<P> Insider disclosure </ P> <P> decrypt "Impact" probe </ P> <P> January 12 this year launched "Deep Impact" probe has so far flown 400 million kilometers or more. .It consists of two parts: one aircraft, about the size of a hatchback car is actually a spaceship; the second is the external copper alloy reinforced by the impactor, weighing about 400 kg, nearly the size of a home refrigerator. .Near the nucleus of the comet Tempel 1, the impactor spacecraft will be ejected, and its nearly 8,000 kilometers in a safe location next to impact the process of observation. .After the impact, the use of optical imaging and infrared spectrum of comet debris material within the scan, more than 10 seconds after impact study within the nucleus of the changes, the impact process, the formation of craters and pits within the image, and the impact for the comet nucleus .pit within the energy spectrum, and store, send images and spectra data, but also to receive the data back to the impact tank, collect samples of comet material inside, the structure and composition of the comet nucleus. .</ P> <P> signature CD sent to </ P> <P> currently has 625,000 signatures carved in the CD will go up at impact to the comet. .This signature event is from May 2003 to the end of July 2004. .By the United States launched the famous SPAC E.com website. .It is said that this CD with a special material, some impact will be destroyed. .In addition, Minnesota called Meadow Creek middle school, high school students McLellan Deep Impact to launch a head measuring the activities of the weight of copper, he launched more than 50,000 students gather gold coins, weighing about 300 pounds. .This machine is the head of the comet impact the weight copper (United States coins are made of copper). .In order to achieve this plan, the school is located on the inhabitants of Andover town all mobilized to collect coins to these students. .Finally, these children are again the money donated 500 dollars worth of Ukraine sister schools. .Thus, Deep Impact has done a very good popular science propaganda. .</ P> <P> watch a variety of ways "Crash" </ P> <P> amateur astronomers looking through a telescope, can see the comet would have darker, after impact, the comet was brighter. .In the hours after impact, the brightness will increase 15 times to 40 times, and reached six luminosity, which is the naked eye can see the minimum brightness. .But it is estimated. .</ P> <P> the best observation point estimate or in California, the Pacific West Coast. .At this time, although the comet is on the horizon, but Australia could not see. .Moreover, even if the U.S. West Coast, it also depends on whether the cloud was more. .</ P> <P> observable astronomy enthusiasts, in addition to watching NASA TV live broadcast, but also to the NASA Web site www.nasa.gov/multimedia/nasatv/; or 14 hours after impact, the Pacific Canary Islands .radio telescope on the set photo shoot will direct spread to a site called SLOOH.com. .The eastern United States such as New York and Washington is estimated to be 19 hours later to see the impact of the image (then, just the United States at the National Day fireworks.) .</ P> <P> "Deep Impact" will not cause danger to the Earth </ P> <P> 7 4, NASA's "Deep Impact" program will be 130 million kilometers from Earth at the implementation of the staged scene ."guns hit the comet," the scene. .Experts in charge of the plan, the plan to destroy the possibility of very small comet, present and future Earth will not cause any danger. .</ P> <P> NASA scientists say they do not really know "the first missiles of copper" and the comet Tempel 1 to 10.3 km per second, the speed of the collision what will be consequences. .According to projections, the impact can produce the equivalent of 4.5 tons of explosives caused the massive explosion, and the comet hit the surface of a football field about 14 storeys deep pit. .</ P> <P> However, this impact can only speed the comet's own change of 0.0001 mm per second, appears to make its recent narrow point about 10 meters, the operating cycle less than 1 second. .In comparison, when the comet Tempel 1 in 2024, after Jupiter, by the gravitational influence, the recent change in point 34 million km. .In other words, a human "Deep Impact" project the impact of comets, and natural staged between the comet and Jupiter, "pass" scene than almost negligible. .</ P> <P> scientists noted that the impact is very unlikely to destroy the comet. .NASA's Jet Propulsion Laboratory, "Deep Impact" Tangyuemansi exploration program scientist, said: "From a scientific point of view, 'Deep Impact' program is like a mosquito to burst into a Boeing 767 passenger plane, will not .affect the orbit of the comet itself.
