Near-Earth Asteroids Research Paper

NASA is a key player in our technological growth. It leads in innovating technology development in both public and private industries across the board from aviation to zoology. In add-on, increasing the space program funding may increase our defense. As it will be exceedingly important that America innovates its space program for defense, from telecommunication to aviation. Likewise, what if an asteroid comes in our proximity and threatens our existence?, we ought to have something

pag). This seems to be the case because from the beginning, one creature has emerged into a more-developed one. It would be logical for humans, being the most evolved, to emerge into a greater creature with something of "superhero" qualities, one who would be invincible, and a species that would never perish. In comparison to this theory, anthropologist, John Hawks, states, "If in the far distant future, habitable planets beyond our solar system were colonized by Earth migrants, that could provide the necessary isolation for new human species to evolve" (Owen; n. pag). Although this seems highly likely to many, human evolution will cease to exist after this meteor hits Earth. Humans are a very vulnerable and fragile species, a species that can only handle so much. David Christian of Big History says that "humans would drown if we were left in water for too long and would freeze or asphyxiate if we were shot ten kilometers into the atmosphere" (Christian; n. pag). This is exactly why the theory of the destructive meteor is, in fact, accurate. If, or when, this meteor strikes, humans will face the same struggle in which the dinosaurs faced and they too will be classified extinct. The magnitude of this meteor will act like a self destruct button, destroying everything in its path, leaving no sign of further evolution

Basically when the asteroid impacted earth it most likely killed the bugs, insects and small animals that walked or were in the ground at the time.

Although it may seem that we do not have problems in space, we actually do, asteroids are coming earlier than ever before in the chart Known Near-earth Asteroids claims that in 1986 there were barely 2000 NEAs and in 2013 there was over 12000! This shows that we need to prepare for bigger asteroids that could come at anytime! Imagine how that chart could go up in the next decade. NASA should fund asteroid studies because they could come up with a way to defend our earth from big asteroids.

Many people including myself believe this because it could help our economy. According to NASA.Gov “the meteorites could contain precious metals, minerals, and even new elements that could be added to the periodic table” They could be used on Earth with trade value. This would give The U.S a humongous boost around 10 billion dollars to our GDP (gross domestic product value). The asteroid

Back in 1980s there was barely asteroids seen near Earth, but as the years goes by there has been more asteroids near Earth. Also there have been more than 12,000 asteroids seen near Earth in 2013. What I think is that NASA should fund asteroid studies because for more resources, safety, and that were competitive and current in the world (#1 winner).

Apollo asteroids are small celestial objects in comparison with other planets but are large enough to cause significant damage to earth and organisms living in its environment. Present 30 known asteroids are with diameters ranging from 0.2-8km. Orbital perturbations by the planets might cause asteroids to collide with earth. The probability of an asteroid colliding with the earth is well defined and certainly non-zero. Earth and the asteroid might meet the intersection point where the asteroid would be able to strike our planet. An impact from such asteroid would create an enormous crater being 20 times the size of the celestial body itself. After impacting the earth's lithosphere it would eject the mass from the crater about 100 times the

“Oh no, a small field of asteroid the size of Pluto is heading towards Earth on a direct collision course!” The Earth and all of its inhabitants are now facing certain extinction. What are the Earth’s inhabitants to do? Is it possible to move the planet out of the way in time? Fortunately for humanity, there are many ways to actually change the Earth’s orbit both plausible and unrealistic, but one must completely understand the physics behind each option so that no mistakes are made and we fully avoid suffering any consequences. First background information on our planet needed, Earth has been around for 4.54 billion years, it has a mass of 5.98x10^24 kg, a diameter of 12756 km, a velocity of about 67000 mph, and is about 149,597,890 km away from the Sun. To most this doesn’t sound like a simple task, not knowing the trick is using Earth’s orbit. An orbit is the gravitationally curved path of an object around a point in space, for example the path of a planet around the center of a star system, like in our Solar System (Encyclopedia). In order to change the orbit of a planet, one must consider the difference forces that can influence the planet’s orbit: direct contact, gravitational assistance, solar sails, and the possible but not exactly plausible forces.

The majority of people know that a large asteroid was accountable for the annihilation of roughly seventy percent of all life on Earth sixty-five million years ago, which seems so long ago that it is not really a concern for life now; however, there are an estimated one million asteroids that are orbiting the Sun right now and we can only account for one percent of them. So, that means that there are about nine hundred and ninety thousand other asteroids that we do not know much about that can potentially at any point in time strike Earth. Is this enough to show that the potential threat is in fact real or is there no reason to be alarmed? Scientists fear that if we do not raise awareness on this issue, we the human race may eventually meet a similar demise that dinosaurs and other life met millions of years ago. The main reason asteroid strikes are a problem is unawareness about what they are as well as when and where they are going to strike and the best

Investigating how the comet was formed, when it formed, and where the comet was formed will build upon the previous knowledge already gathered from the Stardust mission. Knowing where the comet will build upon the fact that some of the materials found within the comet are theorized to be formed in the inner regions of the solar system. It will also further research on whether glycine is a material that was formed in the solar system itself or was brought into the solar system by being carried on meteorites and comets. We should fund the extension of the Stardust mission as discovering the origins of the solar system is one step closer to figuring out how the solar system and Earth became the perfect place for the creation of life as we know it. It will also lead to more knowledge about how other planetary systems are formed and galaxies are formed.

Since they do fall to earth a lot, “asteroids typically top the list of extraterrestrial objects that could hit Earth” (Hernandez, 2012, p. 1). This is true but an asteroid would have to be pretty big in order for it to cause mass destruction.

People were looking up at the night sky and dreaming about flying to the stars for over thousands of years. Myths and legends of many nations of the world are full of stories about the journeys to the Moon and the Sun. Currently, manned space crafts and space stations have become almost commonplace in everyday life. Space exploration is undoubtedly essential and necessary stage of the progress of human civilization, but it entailed all the negative aspects of anthropogenic activities. The atomic age polluted the huge space of the Earth, which requires billions of dollars for a cleanup. Now, it turned out that near-Earth space became littered as well. However, it is much more difficult and expensive to clean it up. Space debris

The asteroid mining industry will get nowhere if they can not be sure they even own the materials they mined. Thankfully, there is legislation waiting to be passed in the House of Representatives that will ensure companies own the materials mined from asteroids. Eventually, asteroid mining will become a reality. When it does, asteroid mining will have numerous effects on the global economy.

It has always been a worry of researchers that at any moment an asteroid may hit Earth and cause significant damage. Only recently (the past hundred years or so) have people been able to make equipment powerful enough to detect asteroids coming toward Earth and orbiting Earth. This is a very important step in preventing damage to our fragile planet.

asteroid is going to take, but Earth would definitely be within reach of the asteroid.
