Orbital debris is all sorts of materials that are human made and these objects are orbiting around the earth’s orbit but are no longer usable1. In other words, Orbital debris, also known as Space debris are all sorts of waste materials in space, which are in a state where various problems can trigger. Researchers and scientists are all concerned about the impacts these debris can leave and they are trying to determine any sorts of solution that may destroy the orbital debris causing no harms on the earth’s surface. This research paper primarily focuses on, the total number of orbital debris for years, the causes and problems due to the space junks and solutions to get rid of those waste space materials.
Analyzing the number of satellites
To analyze the number of satellites sent into the space by humans, let’s consider figure – 1. Figure – 1 shows the numbers of satellites sent every year from 1957 to 2014. In Figure – 1, LEO represents Lower Earth Orbit, MEO represents Medium Earth Orbit, GEO represents Geostationary Orbit and there are other space satellites indicated by the orange color3. According to the graph, it can be stated that most of the satellites were sent in the lower orbit of the earth. Starting from year 1957 to 2014, there were 7417 satellites that were sent in space2. From 1965 to 1978, the number of satellites sent in outer space was fairly constant2. In this time period, the maximum number of satellites sent is 177 in the year 1978, and minimum number is 138 in the year 19742. The maximum number of satellites 230 was sent in the year 1984 and this is the highest number of spacecraft sent in the space till now2. During 1979 to 1985, the spacecraft number increased rapidly2. However, from 1986 till 1996, the nu...

Essay on Space Junk and Its Ciaos

- Space debris: the accumulation and collection of trash left in orbit. Space debris is also referred to as space junk, space waste, orbital junk, orbital debris, and space trash. Space junk consists of nonfunctional satellites, old pieces of spacecraft, bits and pieces of booster rockets, lost equipment, and other pieces of garbage. Subsequently, space debris is put into several categories, including but not limited too large and small as well as high and altitudes. All the space debris travels all throughout Earth's orbit....   [tags: Space Debris, Orbital Junk, Space]

Space Debris Essay

- By the third millennium, mankind is actively studying and exploring space. The number of space flights is increasing and they are constantly running into a number of problems. One of these is a question of the increasing contamination of space with objects from our explorations. These objects are better known as space debris or simply said – space junk. Space debris is man-made objects in Earth’s orbit or objects that reenter the atmosphere, including parts that have finished their active existence and are no longer useful....   [tags: contamination, atmosphere, IADC, technology]

Essay on Space Junk and Its Chaos

- Space debris: the accumulation and collection of trash left in orbit. Space debris is also referred to as space junk, space waste, orbital junk, orbital debris, and space trash. Space junk consists of nonfunctional satellites, old pieces of spacecraft, bits and pieces of booster rockets, lost equipment, and other pieces of garbage. The space debris travels all throughout Earth's orbit. During the twentieth century space race, space debris was beginning to be placed into Earth's orbit. This was subsequently done by humans, appropriately after the launch of Sputnik, the first satellite launched into space....   [tags: trash left in orbit, space debris]

Orbital Hybridization Essay

- Hybridization, in summary and in simple explanation, is the combination and transformation of an atom’s original orbitals forming special orbitals to have the ability to bond with others. When an atom experiences and goes through the process of hybridizing, the electron model is modified to depict it using special orbitals to form new molecules. Since it is already known that only valence electrons are used in atom or molecule bonding, only outside, valence orbitals change. Therefore, hybridization does not add or remove any original orbitals associated with an atom but only refigures them....   [tags: atom, transformation, combination, sp, sp2, sp3]

An Atomic Orbital Essays

- An Atomic Orbital When the a planet moves around the sun, you can plot a definite path for it which is called an orbit. A simple view of the atom looks similar and you may have pictured the electrons as orbiting around the nucleus. The truth is different, and electrons in fact inhabit regions of space known as orbitals. Orbits and orbitals sound similar, but they have quite different meanings. It is essential that you understand the difference between them. The impossibility of drawing orbits for electrons To plot a path for something you need to know exactly where the object is and be able to work out exactly where it's going to be an instant later....   [tags: Papers]

The Effects of Marine Debris on Sea Turtles Essay

- The Effects of Marine Debris on Sea Turtles A fact that is tragically unknown by much of the human population is that marine debris has a large effect on sea turtle populations throughout the world during various stages of the sea turtles’ lives. This type of pollution has proven detrimental to the habitats of sea turtles, as well as to their lives. Marine debris can be defined as any manufactured or processed solid waste imported into the marine environment (Campani, et al., 2013). Various examples of marine debris are fishing nets, plastic bags, cans, bottles, and tires ("Marine debris impacts," 2012)....   [tags: marine life, nitrogen levels]

Outer Space Treaty Implications of Orbital Weapons Systems Essay

- During the Cold War, an arms race involving the United States and the Soviet Union's drive for conventional and nuclear forces supremacy. This paper will focus on the nuclear arms development primarily focusing on the Fractional Orbital Bombardment System (FOBS) of the Soviet Union, and the measures taken by the United States to mitigate the capabilities of Soviet orbital bombardment by bolstering missile-warning technologies. The primary focus will be on improvements to ground based radar sensors, but the development of space based sensors aided in the decline in utility of orbital bombardment....   [tags: GPS, National Security, Extraterrestrial Matter]

The Ethics Concerning Space Debris Essays

- The Ethics Concerning Space Debris In more than 40 years of space activities some 3800 launches led to about 25000 observable space objects larger than 10 cm of which 8300 were still in orbit by September 1997. Only 6% of the catalogued orbit population are operational spacecraft, while 50% is said to be due to "decommissioned satellites," spent upper stages, and objects such as launch adapter and lens covers, which are mission related. The other 44% is originating from 140 on-orbit fragmentations....   [tags: Outerspace Essays]

Dynamics of Debris Flows and Rock Avalanches Essay

- "Field observations reveal the importance of soil and rock volume and composition, as well as 3-D geometry of initiation." This is a quote from a lecture that I attended at the University of Missouri Kansas City on April 14th, 2005. The guest speaker was Dr. Richard Iverson, who is from USGS in Vancouver, Washington. It was a very good, detailed lecture, complete with video clips and a power point of his information. He showed us many pictures of computed stress components and total vertical acceleration, also....   [tags: Earth Science]

Space Trash Essays

- Space trash is any discarded object in space that is harmful to every living being on earth. Since the nineteen-fifties we have been launching items into space. With our hopes and dreams in hand we hoped for the best but that is not what happened at all. There are millions upon millions upon millions of space junk in space. Now there is no possible way to get rid of all the debris, but with the cooperation of all nations we can help to stop the spread of this debris once and for all. Space leaders are in danger of all the harmful objects we have put into space....   [tags: space junk, space exploration]
