Asteroids have been around for centuries but scientists have been trying to conduct a machine that will capture the asteroid to protect and mine the material. I think we should fund asteroid studies because we can protect the earth, collect resources, and find new technology. When we capture the asteroid then we can find many different things in the asteroid and probably outside it too. If we fund asteroid studies to protect the earth we can create a device or machine that will collect or destroy asteroids. The main reason scientists need to capture asteroids is to protect the earth from asteroids that may survive the burning sensation of the atmosphere.
Scientists are working on making a machine that will collect the asteroid that is headed to earth. They believe they can protect the earth by collecting it and bringing it back. In the article ¨Tunguska Meteor Impact¨ it states that in 3000 years the meteor that almost impacted the area will come back. Scientists can build a net object to catch the asteroid before it enters earth's atmosphere. Another idea can be a chemical or laser that can damage or destroy the asteroid before it hits but it will most likely destroy the stuff that may be inside it. By doing this scientist can protect the earth and collect its minerals and ores that may be inside it.

The asteroid may contain popular ores like iron or coal. In the article ¨Tunguska Meteor Impact¨ it said that 220 million pounds of space rock heated the air which made the trees and vegetation burn away. If somehow the minerals survive the heat and the burning that comes when it enters the atmosphere, then maybe scientists can mine it and can obtain a new strong mineral. Scientists can now discover a new way to protect humans and other
Not long ago on the 15th of February 2013 an asteroid named 2012 DA14 merely scrapped the earth’s surface by a tiny margin, even closer than some satellites. According to the NASA (National Aeronautics and Space Administration) the asteroid was 17,200 miles above our planet's surface, which may seem a long way from earth. However, in terms how big the earth is compared to the 17,200 miles, we can acknowledge that many people were saved from death.
about to take place. All a meteor is, is a chunk of rock of that is being
The article suggests that an upset could have “disrupted the trajectories of asteroids-normally safely confined to asteroid belts-sending one or more into the Earth.” This is an easy enough idea for the general public to understand yet it is not stated if they know what caused the upset in the first place. And this is where we depend on the researchers to come up with a way of finding this out. They designed a model that would mimic the Solar System 100 million years ago, “based on natural variations in planetary orbits, their proximity to the Sun and their gravitational effects on one another.”
The third inaccuracy I’m pointing out is that the big asteroid is preceded by lots of little ones which hit New York City, Paris, Shanghai, etc. It is possible for the Earth to be pelted by precursors of the main asteroid, hypothetically speaking, if the initial impact with the comet sent shrapnel flying. But that shrapnel would disintegrate quickly, and most likely by the time the shrapnel reaches the Earth, very little would be left. And another thing: why do movie asteroids only target big cities? I bet upstate New York got hit
Most meteors burn up when they enter Earth’s atmosphere. There are a few meteors however, that make it to the surface. The ones that make it to the ground are called meteorites.
It is also a continuing theory that perhaps an asteroid crashed into earth which caused a climatic and environmental changes causing dinosaurs are extinct. The asteroid is trusted to have made a huge depression in Mexico's Yucatan Peninsula. Asteroids are categorized into a number of types according to their spectra. C-type, includes more than seven five percent of known asteroids: tremendously dark; similar to carbonaceous chondrite meteorites; approximately the same chemical arrangement as the Sun minus hydrogen, helium and other volatiles; S-type, seventeen percent: relatively bright; metallic nickel-iron assorted with iron- and magnesium-silicates; M-type, most of the rest: bright; pure nickel-iron. There are also a dozen or so additional rare types.
According to Canadian researchers, hypothetically, it would take approximately 1,591,500,000 pounds of force to move the moon which I have calculated from the average mass, velocity, and time of impact of the asteroid that struck the moon, this asteroid would not have enough force. Once the asteroid hit the moon even with its apparent density it would not move the moon, it would only cause another crater on the moon’s surface, possibly deep or wide crater though. For the sake of this essay, let’s say it did move the moon and started the descent, the effects would not show on earth for a while, which brings me to my last
Armageddon begins by showing the destruction of the Earth by an asteroid 65 million years ago, when the dinosaurs inhabited the earth. According to the narration, the asteroid is said to have been six miles wide, with the power of 10,000 nuclear weapons. The after effects were trillions of tons of dirt and rock thrown into the atmosphere, creating a blanket of dust that the sun was unable to penetrate for 1,000 years. The narrator explained that it happened once, and that it would happen again, it was only a matter of when.
The extraterrestrial impact theory is that scientists have found logical evidence for if there was a large asteroid. The biggest point of evidence for it being an asteroid was that there was a 150 kilometer wide crater that was found off the coast of the Yucatan peninsula. Scientists calculated that the asteroid or comet was traveling at 30 kilometers per second. For months, scientists concluded that after the impact, clouds of dust blocked the sun and cooled the Earth to a deadly level for plants, and inturn many animals. After the dust settled, greenhouse gasses created a smolder...
An opposing theory proposes that the impact of asteroid or comet caused catastrophic destruction of the environment, leading to the extinction of the dinosaurs. Evidence to support this theory includes the discovery of a buried impact crater (thought to be the result of a large comet striking the earth) that is 200 km (124 mi.) in diameter in the Yucatan Peninsula of Mexico. The spray of debris was blown from the edge of the crater. The debris has been found over large regions of North America. Comet enriched material from the impact's fiery explosion was spread all over the world. With radiometric dating, scientists have used the decay rates of certain atoms to date the crater, spray of debris, and fireball layer. Using similar techniques to date the dramatic changes in the record of microscopic fossils, they have found that the impact and the dinosaur extinction occurred nearly simultaneously.
A comet is composed primarily of ice and rock. Comets are thought to be remnants from the formation of the solar system, which occurred over four-and-a-half billion years ago. Comets have three main parts: the nucleus, the coma, and the tail. The main part of the comet, where the majority of its mass is located, is the nucleus. Like stated earlier, the comet is composed of ice, rock, and dust particles, all of which are located in the nucleus. This is actually the only “natural” part of the comet; it is the only part of the comet that is not formed from the effects of external forces. The coma of the comet is located around the nucleus. It is formed from melted ice and rock and dust sediment. The tail of the comet is also composed of these materials, but, unlike the nucleus and the coma, and as the name suggests, it is located behind the two other structures. These structures make up the entirety of the comet as we view them. The coma and the tail are formed from the effect of gravity and solar radiation. Solar radiation causes the ice to melt, so as to form the two structures, and gravity conforms them into the shapes that we observe in the night sky. These two fac...
He figures out which ones are coming our way, and whether or not they are a threat (Kluger 1). Astronomers estimate that one in a thousand asteroids that pass our Earth will hit us (Booth 98). This may not seem like very many, until you consider that we are hit with at least one basketball sized asteroid every day (Kluger 6). So what happens when our one sizeable asteroid a day ends up being the size of a mountain? Well, if it happened today, we would surely be dead.
An asteroid is a small fragment, composed of rock and metal like irons, found mainly within the asteroid belt; these are left over objects from when the Solar System was created. A meteoroid is a piece of rock or other material present in the Solar System. Critical Thinking Questions 1. How do comets, asteroids, and meteorites influence life on
On February 15 2013 a meteor streaked across sky and exploded over Chelyabinsk, Russia. It set off one of the largest explosion of its kind, according to Western scientists. Flying glass and debris caused most of the injuries from the meteor strike. The shock wave violently jolted the city of Chelyabinsk. Coincidently, it hit on the same day that astronomers were watching another large rock pass Earth by just 17,200 miles. As it turns out, the Earth getting hit by meteorites isn’t so unusual.
When it hit the Earth, the asteroid left an enormous crater that measured 24 miles deep and 125 miles wide (Erdman). Just the impact of the asteroid destroyed the forests and landscape of the majority of North America due to its massive shock wave (Erdman). Many species went extinct when the asteroid hit, these species include dinosaurs, ammonites (certain ocean dwelling creatures), pterosaurs, and some plant groups dinosaurs, ammonites (mollusks related to the octopus and the chambered nautilus), pterosaurs, and certain plant groups. Although devastating, the asteroid did not wipe out all of the animals on Earth, it didn’t exterminate fish, frogs, turtles, birds, mammals and crocodilians (Erdman). These animals survived and evolved into the animals that exist today.... ...
