Space Rocks Research Paper

The history of our solar system is one topic that scientists were able to gain information on due to the Philae mission. “A Success in Space”, an article that reveals the story of the Philae one mission, states, “Researchers consider comets the remains of the ancient solar system.” (Keady 5) This quote shows that comets can be a key to finding more about the remains of the solar system from long ago. Ashley Yeager, the author of the article “Comet probe may shed light on Earth’s past” wrote, “By studying these hunks of rock, dust and ice, scientists hope to better understand the early history of the solar system—including Earth’s early years.” (8) This example proves that scientists hope that comets can help them assimilate more information on the history of our

Despite a family history of geophysicists and rock enthusiasts, I’ve never found the subject of rocks particularly fascinating. However, an exploration of Earth Science has lead me to the discovery that rocks are actually hidden gems (often literally), and that there’s more to the topic than one would think.

The event of September of 1957 Arkansas was part of a movement that change the world as we know starting with The Little Rocks Nine. Nine African American students were placed in a white only school district in hope to merging into a better enhancement and transformation of a country that isn’t a reflection of racial inequalities and segregation. Meanwhile, it was an event that was fought and rebel against by many white officials and citizens in effort block these students from entering the schools because it was in the era's when the Jim Crows were still in effect. Many couldn’t accept revolution because they were content with where its stood then Therefore, bigotry behavior was accepted and consider reasonable. However, all African American

Rocks: Students learn about rocks through the use of a film. The student uses a white board to take notes, and organizes notes with the use of a graphic organizer.

mafic rock, with predominance of mafic minerals pyroxenes, olivines and calcic plagioclase; these rocks (example, basalt) are usually dark colored, but not always, and have a higher density than felsic rocks. ultramafic rock, with more than 90% of mafic minerals (e.g., dunite)

A mineral is a naturally substance that happens, in this process an inorganic material creates a solid crystal like material that has a specific chemical composition. All the matters that make up a mineral are natural and made up from the earth and do not have living matter in them. The structure makes it three dimensional, which means that it has a particular shape that repeats itself. Now compared to a rock, which is also an inorganic material, however it has not certain atomic structure compared to minerals. Rocks are made up of several different minerals, which have been “stuck” together in a geological process that formed

What makes someone suffer? Does being tormented make you suffer? Is being made fun of by peers suffering? The Scarlet Letter by Nathaniel Hawthorne is set in an old Puritan society where many people are persecuted for not following religion in any way whether it is a small sin or a large sin. Hester Prynne is the greatest sufferer in the novel because she was publicly humiliated in front of the whole town and has been an outcast for most of her life in that town.

Unlike Igneous rock, sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Some examples of sedimentary rocks includes conglomerate and limestone. The other type of rock; metamorphic rocks are formed under the surface of the earth from the metamorphosis that occurs due to intense heat and pressure. The examples of this rocks includes gneiss and marble.

Along with the technological advances and new theories of the last century, humans have developed a need to explore beyond the known of the final frontier. This resource of knowledge has led to superstitions and concerns about what could happen if people pursue this want of space exploration. Among these concerns are national finances, the world’s health, and ethical standpoints of what really could be waiting on the other side for those who dare venture into the unknown.

Moons have formed from circling discs of gas and dust around their parent planets, while other moons are thought to have formed independently and later have been captured by their planets. “With the anticipated discovery of Earth like planets in habitable zones, the development of a unified model for the formation and evolution of our solar system is timely,” was said by Martin Bizzarro. By knowing the history and evolution of our solar system, so far, its crazy thinking about how much it can change in the future. Scientists use a collection of different techniques to gather information on the constantly changing in atmosphere and space. For example, scientists use robot spacecraft to make measurements of the planets and their planetary systems. We mostly know of these as space probes, or satellites. The first space probe to go into space was Sputnik 1. It was launched October 4, 1957, by the former Soviet Union. On January 31, 1958, the United States sent a probe called Explorer 1 into space. Mars is currently holding 5 active space missions, that that is Mars Odyssey, Mars Express, Mars Reconnaissance Orbiter, Opportunity Rover, and Curiosity Rover. (And I think we can all agree that the names have definitely gotten better!) Those are just the active missions on Mars, as well. There are so many spacecraft gathering information right now. Another form that scientists use is

Stardust collected the particles without destroying them for the analyzation of interstellar dust for data and information to study for NASA. Most of the particles that Stardust collected from the comet are smaller that human hair. More than 1000 particles were collected and complete for analysis by scientists. This encounter took place in space, 242 million miles from earth. On Jan 19, 2006 the capsule with samples was separated from the spacecraft and successfully returned to Earth. The capsule was recovered by a chase aircraft in the Utah desert by NASA team of scientist. They concluded and found interstellar dust particles within the Stardust capsule in 2006, ten years ago. The team consisted of 200 international scientist employed by NASA. The comet's location is in the outer solar system within Kuiper Belt beyond Pluto. This comet was new to its orbit and still has most of its dust particles and gases. However the mission was successful and completed on Jan 15, 2006 with the return of the capsule. The Stardust mission samples indicated that some comets may have included materials ejected from the early sun and may have formed very differently than scientists had theorized. Scientists that studied samples of Comet Wild 2 and found that the minerals formed under extremely high temperatures meaning close to the sun and not in the freezing cold at the Solar System's edge, where most short lived comets come from. "In the coldest part of the solar system we've found samples that formed at extremely high temperatures," said Donald Brownlee, during a press conference. "When these minerals formed they were either red hot or white hot grains, and yet they were collected in a comet, the Siberia of the Solar System." Stardust ceased operations in March

Asteroids are large or small chunks of rock and metal flying around space up to speeds of 80 000 km/h. These chunks were believed to have formed millions of years ago during the "big bang". These rocks didn’t form any planets and

     Igneous rocks are classified first by texture. This is broken down mainly into grain size. First there are intrusive, or plutonic igneous rocks. These types of rocks cool within the crust and forms large, visible crystals. The opposite would be extrusive, or volcanic rocks. These cool at the surface rapidly, forming small grains. A combination

Space can be excellent. The planets, stars, systems and nebulae make effortless and vivid shapes noticeable to our telescopes.

Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.
