A Positive Nuclear Weapon Used For Asteroid Deflection?

After hearing this podcast I am very interested in learning more about asteroids, comets, or what have you and what can be used to stop them from doing damage. The talk about nuclear explosives came into play and there really is no reason to not use them if it is found it works effectively. Preventing harm to citizens and damage to our country’s land is not what any of us want to happen I’m sure. After doing research I found how “NASA discovered that nuclear explosives are way more effective for asteroid deflection than non-nuclear explosives, due to the sheer amount of energy they produce.” (Culley) NASA also tested four nuclear scenarios which included a surface explosion, a delayed surface explosion, a subsurface explosion and a standoff explosion which is where the bomb doesn't come into contact with the asteroid at all. The surface and subsurface explosions were found to be the most effective, but there was a good chance of splitting the asteroid. In the end, the space agency determined that a series of standoff nuclear explosions would be the most effective way to deflect an asteroid headed for Earth. The next best way and non- was a kinetic impact which is wear the asteroid is struck by objects. This required too much detailed knowledge of what the surface of the asteroid is like so back to nuclear explosives we go.
A project called AIDA which is short for Asteroid Impact and Deflection Assessment mission, is trying to take on another strategy and plans to crash a spacecraft traveling at 14,000 miles per hour into the smaller of the two what are called Didymos asteroids in the year 2022. These asteroids have no chance of hitting Earth, according to scientists at the 44th annual Lunar and Planetary Science Conference this year. The website stated how “A Johns Hopkins University's Applied Physics…...

When Asteroids Strike

...explosion was an asteroid from space that was on a collision course with the earth; in February of 1994 the asteroid struck. “The asteroid actually broke into several pieces, with one large piece detonating about 34 km above the surface, and a second, much larger piece detonating at an altitude of approximately 21 km” (Tagliaferri, 1998). Scientists were lucky to record this data via satellite to study the force an asteroid can have when impacting firsthand. There is evidence of asteroid impacts covering the surface of the earth and other surrounding planets in space. There are also many theories involving asteroid impacts causing mass extinctions on Earth, the most common being the extinction of the dinosaurs 65 million years ago (deGrasse Tyson, 2005). Most of the impact evidence shows that the earth has been attacked by these asteroids since its formation billions of years ago. Evidence all around us tells us that the Earth will be struck, and another major asteroid impact will occur. The most common and highly argued impact event is the one that may have wiped out the dinosaurs. This event in itself has many theories, but the one common element in most sound dinosaur extinction theories is that a major impact event occurred around the same time the dinosaurs stopped roaming the Earth. Most of the scientific community agrees that an asteroid impact did destroy the dinosaurs. Some scientists; however, claim that the dinosaurs were dying off well before the asteroid......

2012 Da14

...On February 15, 2013 the small asteroid 2012 DA14 was its closest to Earth. The 50 meter asteroid passed through the gap between Earth and the ring of geosynchronous satellites that orbit earth. Geosynchronous objects orbit around the earth with a period equal to one sidereal day. Asteroid 2012 DA14 passed at about 17,200 miles above the Earth’s surface. The asteroid was discovered in February 2012 by astronomers at the LaSagra observatory in southern Spain. (http://neo.jpl.nasa.gov/news/news177.html)( http://neo.jpl.nasa.gov/news/news174.html) (http://www.merriam-webster.com/dictionary/geosynchronous) An asteroid is a small planet-like body in orbit around the sun. The orbits of some asteroids take them across the paths of the planets. Asteroids are smaller than a planet but 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...

In the past decade or so there have been some instances that have gain the attention of the higher ups to do something to combat this treat but it isn’t enough. For where they lack the are some people willing to step to the plate to make life on the wonderful planet safe from these planetary disaster bringers. Early morning of the 15th of February 2013, a bright flash is seen over the southern region of Ural in Russia followed by a window shattering shock wave injuring over 1500 people. June 17th 2002 a large asteroid was discovered floating between earth and the moon. It would have been a routine spotting of an asteroid except for the fact that 3 days prior it was one of the closest passing asteroids in a long time. Not only that, with its size and if it had entered our atmosphere, it could have easily destroyed a city the size of New York without a trace. In both situations had we detected these asteroids with enough advance notice, we could have at least been prepared or some contingency plan in place. Alas our current NEO or Near Earth Objects, 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......

...defined as heavenly bodies or solar system objects that have been pulled gently by the gravitational force of the Earth bringing them close to into orbits and the Earth’s neighborhood. These NEOs include Near-Earth comets, Near- Earth asteroids, meteoroids and a few solar-orbiting spacecraft huge enough to be trailed in space before hitting the Earth. The collision of the NEOs in the past has had a significant part in shaping the biological and geological history of the Earth. Near-Earth asteroids (NEA) have orbits that rest between 0.983 to 1.3 astronomical units from the sun (Shapiro, 1999). Due to this the Earth’s orbit cross with some NEA orbits posing a collision danger. By 2012 August there were 848 Near-Earth asteroids that were larger than 1km and 154 of those had were potential hazardous asteroids (PHAs).Comets are mostly composed of ice water with engrafted dust particles. They are formed on the outer system of the planet. The asteroids are mainly rocky and are formed in the warmer inner solar system between the orbits of Jupiter and Mars (Bally, Reipurth 2005). Scientific interest in asteroids and comets is due to their status because they have unchanged debris from the solar system formation dated back to up to 4.6 billion years ago. Asteroids and comets give hints to the chemical mixture from which the planets took shape 4.6 billion years ago. NEOs are of high interest also because they present interesting scientific opportunities for both astronomical and direct......

Evolution of the Sun Moon Earth and Planets

...fifty-eight moons, thousands of asteroids, and billions of meteoroids and comets and one dwarf planet named Pluto orbit the grand star, the Sun. Around and around they go. These planets and other object came from a huge explosion. The Big Bang Theory, which states that the universe began as a dense and hot point that was less than a fraction of an inch and has continued to evolve into what it is known as of today. The origin of the galaxy seems a mystery. But over time, the pieces of the puzzle are coming together. Scientists believe a supernova or star may have formed the universe. When the Earth first formed, it contained gasses which dissolved into the Earth’s molten planet. When this formation happened from the smaller bodies, these were called planetesimals. But not all planets are the same. The Jovian planets are shrouded by thick atmospheres that are rich in hydrogen and helium. These planets were formed away from the sun. A shooting star is what individuals think of when they see a vapor stream of dust and gas shooting across the sky. The sun helps make this spectacle possible and could be a reason why early astronomers were so curious about the skies. When an individual looks up at the night sky, he or she can get lost in the vast beauty. Who wouldn’t get mesmerized? Introduction Our solar system consists of the Sun, eight planets, the dwarf planet Pluto, fifty-eight moons, thousands of asteroids, and billions of......

Conceptual Physics

...Conceptual Physics Assignment 1 Part 1: Essay Style Question: Why does an asteroid explode when it hits the earth? This is simply an application of the laws of physics. It is caused by the large amount of mass contained in an asteroid, moving at such a high velocity with an enormous amount of kinetic energy. For example: and the . Take an example radius of 10km. Therefore the and the We can then calculate the Kinetic Energy of the Asteroid using: Taking an example velocity of 30 km/s this gives us a Kinetic Energy of . We can see from our lecture notes that an Asteroid’s energy per gram is 165 times that of TNT. Therefore: This is a huge amount of energy! This energy is released in the form of heat and light as the asteroid enters the earth’s atmosphere due to the friction of the atmosphere slowing the asteroid down. The density of the gas molecules in the atmosphere causes this friction. This rapid release of heat energy is enough to cause an explosion! Also a lot of the time these asteroids contain ice or frozen carbon dioxide. If this is rapidly heated up, it can boil and pressure can build internally and can cause an explosion from inside the asteroid. All of these factors can account for an asteroid exploding. Overall it is all down to the Principle of Conservation of Energy. The energy is converted from chemical energy into vast amounts of light and heat causing the rapid release of energy in the form of an explosion. Conceptual Physics Why if a stick of...

Comets

...hyperbolic trajectories. Comets are distinguished from asteroids by the presence of an extended, gravitationally unbound atmosphere surrounding their central nucleus. This atmosphere has parts termed the coma (the central atmosphere immediately surrounding the nucleus) and the tail (a typically linear section consisting of dust or gas blown out from the coma by the Sun's light pressure or outstreaming solar wind plasma). However, extinct comets that have passed close to the Sun many times have lost nearly all of their volatile ices and dust and may come to resemble small asteroids.[1] Asteroids are thought to have a different origin from comets, having formed inside the orbit of Jupiter rather than in the outer Solar System.[2][3] The discovery of main-belt comets and active centaurs has blurred the distinction between asteroids and comets. As of August 2014 there are 5,186 known comets,[4] a number which is steadily increasing. However, this represents only a tiny fraction of the total potential comet population, as the reservoir of comet-like bodies in the outer Solar System may number one trillion.[5] Roughly one comet per year is visible to the naked eye, though many of these are faint and unspectacular.[6] Particularly bright examples are called "Great Comets". On 22 January 2014, ESA scientists reported the detection, for the first definitive time, of water vapor on the dwarf planetCeres, the largest object in the asteroid belt.[7] The detection was made by using the......

After several smaller meteorite showers Nasa discovers the enormous asteroid and realize they don’t have much time to figure out how to somehow stop the asteroid or else the human race will become extinct. Their plan is to land on the asteroid and drill into the middle of it and drop a nuclear bomb. This would cause the asteroid to break in two halves and hopefully miss the earth. But in order for the plan to work Nasa needs the best oil driller there is. Harry Stamper is a very experienced driller who has his own oil rig in the ocean and he is the one they want. Meanwhile, Harry is having his own set of problems; one of his workers, AJ is taking many risks with the drilling which endangers his whole crew. On top of that His daughter is also in a relationship with AJ and does not want to end things with AJ even though her father, Harry does not approve. When Harry is approached by......

...SOLOR SYSTEM ABSTRACT The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, dust and gas. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. The main asteroid belt lies between the orbits of Mars and Jupiter. The planets of the outer solar system are Jupiter, Saturn, Uranus and Neptune (Pluto is now classified as a dwarf planet). Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is, the more gravity it has. Because the Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it. At the same time, these objects, which are moving very rapidly, try to fly away from the Sun, outward into the emptiness of outer space. The result of the planets trying to fly away, at the same time that the Sun is trying to pull them inward is that they become trapped half-way in between. Balanced between flying towards the Sun and escaping into space, they spend eternity orbiting around their parent star. Introduction: Humans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earth’s neighborhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the......

Mini-Sats: the Trick to Spying Earth-Bound Asteroids?

... That’s one suggestion for building telescopes to find a city-smashing asteroid before it finds us. Asteroids are space rocks, which can range from boulder sized up to chunks of rock nearly 1,000 kilometers (621 miles across). Most of them orbit between Mars and Jupiter. A fleet of pint-sized satellites orbiting the sun could track down the majority of asteroids that threaten Earth's safety. Or that’s what a team of scientists now proposes. Others aren’t so sure. This plan has holes big enough to drive an asteroid through, some scientists charge. The U.S. Congress directed NASA, the nation’s space agency, to identify 90 percent of all asteroids wider than 140 meters (roughly 460 feet). Congress set a deadline of 2020. The space agency could meet the first goal using five miniature observatories, say scientists on a team that includes Michael Shao. He’s an astrophysicist at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. All it would take, his group says, is to space the satellites out evenly just inside the orbit of Venus. Some astronomers have looked into building and launching a single space telescope, tasked with keeping its eye out for asteroids. Building it could take eight to 10 years and cost about half a billion dollars. But those five mini telescopes could do the same thing, Shao’s group proposed online March 29 on arXiv.org. Once launched, they could find all the high-risk asteroids in perhaps three years — and for just one-tenth a big telescope's cost...

...Smaller Objects in the Solar System Asteroids are small, airless rocky worlds revolving around the sun that are too small to be called planets. They are also known as planetoids or minor planets. In total, the mass of all the asteroids is less than that of Earth's moon. But despite their size, asteroids can be dangerous. Many have hit Earth in the past, and more will crash into our planet in the future. That's one reason scientists study asteroids and are eager to learn more about their numbers, orbits and physical characteristics. Most asteroids lie in a vast ring between the orbits of Mars and Jupiter. The main asteroid belt holds more than 200 asteroids larger than 60 miles long. Nearly all asteroids are irregularly shaped, although a few are nearly spherical. A comet is an icy body that releases gas or dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them snowy dirtballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more. Astronomers think comets are leftovers from the gas, dust, ice and rocks that initially formed the solar system about 4.6 billion years ago. Comets orbit the sun but are believed to be located in an area called the Oort Cloud, far beyond the orbit of Pluto. Meteorites vary in size from a few millimetres across to several feet in diameter. Meteorites are rarely round in shape. They are typically irregular, with rounded edges. The surface of a freshly fallen meteorite will appear......
