Almost 1,000 people were injured when a meteor shot across the sky and exploded over central Russia on Friday, sending fireballs crashing to Earth, shattering windows and damaging buildings.

Definition : Small pieces of space debris — usually parts of comets or asteroids — that are on a collision course with the Earth are called meteoroids. They become meteors when they enter the Earth's atmosphere. Most meteors burn up in the atmosphere, but if they survive the frictional heating and strike the surface of the Earth they are called meteorites.

The site of Friday's spectacular show is about 5,000 kilometres west of Tunguska, which in 1908 was the site of the largest recorded explosion of a space object plunging to Earth. That blast, attributed to a comet or asteroid fragment, is generally estimated to have been about 10 megatons; it levelled some 80 million trees.
The meteor — estimated to be about 10 tons — entered the Earth's atmosphere at a hypersonic speed of at least 54,000 kph and shattered about 30-50 kilometres above the ground. Chelyabinsk city authorities urged people to stay indoors unless they needed to pick up their children from schools and kindergartens. They said what sounded like a blast had been heard at an altitude of 10,000 metres.


The explosions broke an estimated 100,000 square meters of glass. 985 people had asked for medical assistance. The Interfax news agency quoted that 43 people were hospitalized. A fireball blazed across the horizon, leaving a long white trail in its wake. Car alarms went off, windows shattered and mobile phone networks were interrupted. City officials said 3,000 buildings in the city were damaged by the shock wave.

“I was driving to work, it was quite dark, but it suddenly became as bright as if it was day,”
“I felt like I was blinded by headlights,”
Another Chelyabinsk resident, Valya Kazakov, said some elderly women in his neighbourhood started crying out that the world was ending.
Reports conflicted on what exactly happened in the clear skies. There was a meteor shower, but it was a single meteor. Prime Minister Dmitry Medvedev, speaking at an economic forum in the Siberian city of Krasnoyarsk, said the meteor could be a symbol for the forum, showing that “not only the economy is vulnerable, but the whole planet.” Deputy Prime Minister Dmitry Rogozin said the incident showed the need for leading world powers to develop a system to intercept objects falling from space.
Amateur video broadcast on Russian television showed an object speeding across the sky about 9:20 a.m. local time, just after sunrise, leaving a thick white contrail and an intense flash.…...

Case Study believed to be about 1250 kilometers. As per geographical data, the diameter of the earth is 12,756 kilometers. It is again enveloped by the atmosphere, which comprises five major layers, namely, the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The atmosphere provides air, water, warmth, and protects us from the harmful rays of the sun. Without atmosphere, life on earth would be impossible! Meteors burn up when they hit the Earth's atmosphere. Why doesn't the space shuttle? When a small meteor enters the Earth's atmosphere, it goes from traveling through a vacuum to traveling through air. Traveling through a vacuum is effortless -- it takes no energy. Traveling through air is another story. A meteor moving through the vacuum of space typically travels at speeds reaching tens of thousands of miles per hour. When the meteor hits the atmosphere, the air in front of it compresses incredibly quickly. When a gas is compressed, its temperature rises. This causes the meteor to heat up so much that it glows. The air burns the meteor until there is nothing left. Re-entry temperatures can reach as high as 3,000 degrees F (1,650 degrees C)! Obviously, it would not be good for a spacecraft to burn up when it re-enters the atmosphere! Two technologies are used to allow spacecraft to re-enter: * Ablative technology * Insulating tile technology In ablative technology, the surface of the heat shield melts and vaporizes, and in the process, it......

...Harry and Grace (Harry’s daughter) picked who was going to fly in outer space to save the world. The groups had to train before flight so they knew what they were doing once they got up there. A.j messed up but when it came to the real mission he did his best. Most of the team didn’t get to make it back to see their families. When they when they arrived to the Russian satellite they had to fuel up. But then something started to go wrong because it was old. Some people almost didn’t make it out. Once they departed from there before it blew up they had to go to the meteor to destroy it before it hit earth. The groups worked well together. When the shuttles were getting ready to land shuttle two didn’t land very well because it ran into a rock. Shuttle one thought they were all gone but three of them survived. They made it to shuttle on just in time to finish drilling the hole to plant the time bomb to destroy the meteor. Then some stuff started to happen it came down to the point that some had to stay behind so they could push the button to start the bomb. A.j was supposed to do it but Harry took it for the team.

...larger than a meteoroid, which is a small interplanetary object also in orbit around the Sun. If a portion of a meteoroid or other object survives the entry through the Earth’s atmosphere and reaches the Earth’s surface it is referred to as a meteorite. A meteor, also known as a shooting star, is a streak of light produced by a meteoroid that burns away in the Earth’s atmosphere. When their orbit brings them close to the sun, gigantic balls of ice and rock or comets, form a tail of dust and gas while being heated by the Sun’s rays. Scientists believe that the extinction of dinosaurs, nearly 66 million years ago, was the result of a large meteorite striking what today is Mexico’s Yucatan Peninsula. In 1908, a fragment of an asteroid or comet exploded in Earth’s atmosphere above Tunguska, Russia. The “Tunguska event”, the blast caused by the explosion, knocked down an estimated 80 million trees over 830 square miles. On February 15, 2013, just 3,000 miles west of Tunguska in western Siberia, a 10 ton meteor entered the Earth’s atmosphere. The meteor exploded with the force of an atomic bomb. It has been determined that the meteor had no connection with asteroid 2012 DA14. ( ( According to experts, the Earth is hit by a meteorite about 5 to 10 times a year. Meteorites......

Falling Stars

..."shooting stars", but their scientific name is "meteors". Let's learn some more about falling stars. Space looks empty, but there's all kind of stuff out there: gas, dust and tiny rock and ice fragments. The tiny pieces of rock or ice are known as meteoroids. They could have been left over from the formation of the Solar System 4.6 billion years ago. Or maybe they were part of the tail of a comet that was making a near pass to the Sun. Rocks and asteroids can collide with one another in space and generate meteoroid debris. Who knows how long the tiny object was orbiting the Sun until its path finally crossed the Earth. When a meteoroid strikes the Earth's atmosphere, it burns up leaving a tiny trail in the sky. This trail is the falling star, or meteor. The size of the trail depends on the speed of the object, the angle it struck the atmosphere at, and the amount of mass that it has. The largest objects can leave a trail across the sky that lasts for a few seconds. Although you can see falling stars any night of the year, there are certain times when they're more frequent. These are the times when the Earth orbit takes us through the tail of an ancient comet. We'll pass through the tail fragments at the same time every year, so a meteor shower is predictable. Some famous meteor showers are the Perseids in August, and the Leonids in November. So remember, when you're looking for falling stars, you're not seeing stars at all, but meteors; tiny chunks of rock and ice......

Engineering 370i do a fly by and collect samples from preset meteor targets. The next major body of this paper is the actual mission profile of the spacecraft. The mission’s primary objective was to fly by a meteor and collect samples from space and another meteor. This sections will go over where the spacecraft was launched and what its trajectory was. Also, what date it was actually launched successfully. Its first trajectory was aimed towards a meteor called Anne frank. Brief information about the meteor Anne Frank will be given and what the purpose of the meteor encounter was for during the stardust mission. The second trajectory of the spacecraft was a second meteor called Wild 2. Like the first meteor, brief information will be given about the meteor and also why it was a part of the spacecraft’s pre-designated trajectory. The next section of the paper will go over the discoveries that were found during the stardust mission. One part of the section will be about what was gathered from the fly by when the stardust spacecraft came in contact with the meteor Anne Frank. The other part of this section will be about what was discovered and recovered from the second meteor Wild 2. Another things that was part of the mission was to gather dust from space itself. This part of the paper will also go over how the samples were collected and stored while in space. Since the whole point of this mission was to collect samples from space and the meteor, in this section I will also go over how......

...detection methods are not up to par. This is why we need to improve on our knowledge and current asteroid detection methods and systems or be doomed to be a planetary statistic. The Chelyabinsk Meteor in Russia was a lucky break. The speed the meteor enters entered the earth’s atmosphere was clocked at close to 43,000 mph. That’s close to 60 times the speed of sound. Thus, though the meteor did not touch down, the mid-air explosion was powerful enough to send a shock wave that injured over 1500 people and blow out windows over two miles away from the explosion point. The cause of the explosion was due to the breaking up of the meteor upon entry itself. Then there was asteroid MN2002 that was detected on June 17th 2002, three days after it passed earth. Now the Chelyabinsk was 20 meters long but MN 2002 was 73 meters moving at 10.6 kilometers per second, (little over 6 miles per second). Despite the fact that it was a much slower moving object, the share mass of it, if it had entered the earth’s atmosphere and touch down it would have caused enough damage to wipe out an entire city. Current NEOs are under surveillance but not all. Due to the share number of asteroids in our solar system asteroid and the 50- 100 meters in size get little or no recognition. Many scientist that study meteors like Brian Marsden, an astrophysics of the Harvard-Smithsonian Center of Astrophysics, believe that there are over a million of the under 100 meter class asteroids may exist but......

Evolution Scientific Inaccuracies

...The 2001 film “Evolution”, is an entertaining film about an alien species being introduced to earth via meteor. However, this film seems to contain a copious amount scientific inaccuracies. For example, when the meteor is traveling through space, the movie presents the meteor rushing towards Earth with sound. However, space is a vacuum, so there for there would be no sound in space. To continue with the lengthy list, the meteor, after piercing the atmosphere of earth, still remains around the same size, not withering at all through the intense heat and weathering that would occur by doing so. Also, last time I checked, meteors did not contain explosives. I only bring that up because when it impacts, it creates a huge explosion, rather than the dirt or displaced earth that would be sent into the air. Not to mention, the fireman that was there on impact, was obviously still able to drive his car even though the meteor basically destroyed it, I mean, that is totally plausible, right? Now, when David Duchovny and Orlando Jones, who play the role of two college professors, arrive to be the first to investigate the rock, they try to take a sample of the rock to test it. When they break off the piece of rock, it starts to “bleed”. Really, a rock can bleed? Next thing you know, the blood will start transforming into a sentient species! So, after they collect some of the the “blood”, they bring it back to the lab for testing and inspecting. Now, it is my understanding that in......

Meteor based on the mobile operator Meteor; I am going to focus my discussion on the mobile telecommunication industry. During this analysis I will assess what was the catalyst which attracted Meteor to the Irish telecommunication industry in 1998. I will also review Meteor’s strategies when entering the market and discuss how these adapted to external changes in the business environment. Finally I will voice my opinion on how I see the telecommunication industry evolving over the next five years. Attractiveness of the Telecommunications Industry in 1998 * In my opinion, the catalyst which attracted Meteor to the mobile telecommunications industry in 1998 was the deregulation of the market in December of that year. This removed any rules which may have restricted competition in the Irish telecommunications market. There was now an opportunity for a new mobile operator to promote their services and abolish what was, at the time, a duopolistic market between Eircell and Esat Digifone. Before then, the telecommunications market was heavily regulated and it would have been very difficult for meteor to enter this capital-intensive industry. The deregulation of this market indicated that the government wanted this industry to thrive and develop, with an aim to “further stimulate the use of mobile phones in Ireland and reduce tariffs”. I believe that this government approval also enhanced the attractiveness of the industry as Meteor knew that should they require......

Symbols of the Scarlet Letter

...helps to point out the ultimate meaninglessness of the community's system of judgment and punishment. The child has been sent from God, or at least from nature, but the letter is merely a human contrivance. Additionally, the instability of the letter's apparent meaning calls into question society's ability to use symbols for ideological reinforcement. More often than not, a symbol becomes a focal point for critical analysis and debate. The Meteor As Dimmesdale stands on the scaffold with Hester and Pearl in Chapter XII, a meteor traces out an A in the night sky. To Dimmesdale, the meteor implies that he should wear a mark of shame just as Hester does. The meteor is interpreted differently by the rest of the community, which thinks that it stands for Angel and marks Governor Winthrop's entry into heaven. But Angel is an awkward reading of the symbol. The Puritans commonly looked to symbols to confirm divine sentiments. In this narrative, however, symbols are taken to mean what the beholder wants them to mean. The incident with the meteor obviously highlights and exemplifies two different uses of symbols: Puritan and literary. Pearl Another huge symbol in the novel is Pearl. She is a constant reminder of her mother's sin. When Hester removes her letter, Pearl screams and shrieks until she replaces it on her bosom. Hester cannot be associated without the scarlet letter and her sin. Although Pearl is a complex character, her primary function within the novel is as a......

Analytical Review of Discover Magazine

...reaching their peak potential or if breeders are more focused on breeding sprinting horses. Those that may be interested in this type of article may include but are not limited to stable owners, horse breeders, large animal veterinarians, and those that attend horse races (such as the Kentucky Derby). In the April 2015 issue of Discover magazine there is an article regarding how to view meteor showers. According to the magazine the Lyrid meteor shower is supposed to be a spectacular sight. Unfortunately the meteor shower was in April of 2015; however it will occur again in 2016 around the same time of year. The meteor shower was to occur the week of April 16th through April 23rd with the most spectacular results taking place hours before sunrise on the 23rd. The Comet Thatcher orbits the sun every 415 years and sheds particles into the Earth’s atmosphere causing a meteor shower. If one would like to observe this particular meteor shower (which scientists believe will be more spectacular than most) one needs to travel at least thirty miles outside city lights. The article explains that the meteors will be best seen if looking at the constellation Lyra. Those that want to view the shower need no special equipment as the shower was promised to be bright enough to view with the naked eye. The article also suggests bringing a reclining lawn chair, a blanket, and a warm beverage for comfort. Those that may be interested in this type of article may include but are not......

Hester considers the scarlet letter A to be the Black Man’s mark, and Pearl wonders aloud if the Black Man left his brand on Dimmesdale’s heart. Our narrator loves to compare Chillingworth to Satan as well. By invoking Satan, our narrator raises the question of whether humans are innately good or evil.
