Abstract
This paper discusses what the universe is made up of, its age, how stars are formed and what is the future of our solar system. It discusses the history of the exploration of the universe. The author explains how In this century large telescopes are set up, far away from city lights and traffic to gather the best data for studying the skies. A brief overview of the theories on the origin of the universe is also given. The author concludes that although new theories are constantly being proposed and science is constantly to answer the question ?Where did we come from?? , until now, no answer has satisfied everyone.
From the Paper
"Man's fascination with the heavens is as old as recorded history itself. Astronomers from all civilizations?medieval to the present times?carefully observed the stars and their relative position in the night sky. Even in the medieval times, astronomers universally observed two features: that stars tended to drift westward with each passing night; and, despite this apparent movement, stars were always in a fixed position relative to each other. Anything that man could not explain, ending up fascinating him?as did the stars. It has been stated that when man loses his desire to explore the unknown, the human race will have sounded its own death knell."

Abstract
This paper talks about the ways in which the shuttle is designed to overcome basic heat transfer problems during launch, orbit and re-entry. The main points in this paper are the active and passive systems in the TPS and the history of the shuttle design.
From the Paper
"10...9...8...Patiently the Space Shuttle waits on the launch pad...7...6... everything is in place...5...4... all functions are working properly...3... the conditions are comfortable on the coast of Florida, and the temperature is nice and warm...2...1... IGNITION! (Figure #1) The sudden burn of the rockets jolts the humongous craft to life. As streams of flame shoot out its lower portion, the craft begins to inch skyward. In no time its speed has increased, and it begins hurtling through the air towards its mission. While still inside Earth's atmosphere, the airflow over the Shuttle begins to warm the craft's surface, until it becomes "white hot." Then, the craft breaks free of the atmosphere's restraints, plunging into the freezing void of outer space. The Space Shuttle must be able to withstand these temperature extremes and still accomplish its mission objectives. After the mission, as the craft returns to Earth, it again encounters tremendously high temperatures as it re-enters Earth's atmosphere. The Shuttle encounters a lot of atmospheric resistance and slows itself down through this phase, then finally glides to a comfortable rest at Edwards Air Force Base in sunny Southern California, where the astronauts and craft must prepare to begin the process all over again. These intense hot and cold extremes drive scientists and design engineers as they work to control the internal temperature of the space shuttle throughout the various phases of its journey. They do this by using many creative systems such as specially designed tiles and radiator systems, to both reflect and radiate heat that would otherwise be dangerous to the craft and crew."

Abstract
This paper details how Galileo Galilei affected history by discovering the potential of the telescope, pioneering new approaches to science, and challenging the authority of the Catholic Church.
From the Paper
"Galileo Galilei was a mathematician, an astronomer, and a physicist who made several significant contributions to modern scientific thought. During his life, he made many scientific discoveries, often in contradiction with the centuries-old ideas of the Greek philosopher Aristotle. These contradictions led to great conflict with the Catholic Church; however, he emerged as a symbol to others who oppose unyielding authority and champion scientific progress. As James Reston?s biography Galileo makes clear, Galileo is a historical figure who affected history by discovering the potential of the telescope, pioneering new approaches to science, and challenging the authority of the Catholic Church."

Abstract
This paper discusses the history of NASA from its beginnings and the political framework surrounding its genesis and the beginnings of the Space Race.
From the Paper
"Since the beginning of time, man has been an avid explorer. From exploring his nearby surroundings to traveling to the other side of the world to journeying to the stars, man has been on the move constantly. Mankind is a species of risk takers and curious about all that surrounds him. Before man's decision to fly to the stars, one of the biggest eras of exploration was the navigation and exploration of the seas and the inner continents they found themselves upon. Through all of the explorations, it has taken the political and financial backing of the many nations that supported these explorers. And what was the purpose of these explorations beyond curiosity? It seems that the political will of the nations encouraged these explorers to discover and conquer faster than the next nation. It was and still is a matter of national pride; more often than not, it was also a matter of national security, whether real or imagined. The history of NASA reflects this ideal; that exploration isn't always done just for the sake of discovery."

Abstract
This paper explores comets; the astronomical bodies made up of frozen gases and dust particles, which orbit the solar system. The author discusses how comets develop, their structure, their volatility, and the important role that comets play in the revolution of astronomy and cosmology. The paper also contains a detailed description of Halley's Comet.
From the Paper
"Comet structures are diverse and very dynamic, but they all develop a surrounding cloud of diffuse material, called a coma, that usually grows in size and brightness as the comet approaches the Sun. Usually a small, bright nucleus (less than 10 km in diameter) is visible in the middle of the coma. The coma and the nucleus together constitute the head of the comet."

Abstract
This paper details of the space race between the United States and the Soviet Union during the Cold War and how and why it was a show of power and superiority. The author looks many different aspects of the space race including, its purpose, how it was used to show the other country its weaknesses, how it enabled both countries to explore the uncharted vastness of space and find for it new military and how they attempted to use the moon as the ultimate propaganda tool.
From the Paper
"Even though Sputnik had no direct military impact, it showed the progress of the USSR in science and military and prompted the US government to pay more attention to its own missile operation (McGhee 331). The media played a major role in spurring the government to take action. Sputnik was front-page news on all the papers and it had all of America wondering how something like that could happen without anyone knowing (Schefter 23). At first the US government was not impressed by the Soviet's accomplishments. President Eisenhower felt that the U.S. people had acted like children and that no response to Soviet actions was necessary (Burrows 200). He felt that the US needed to toughen up for a long war they may have in the future and did not see the US as being in any competition with the Soviets (Burrows 200). He even went so far as to congratulate the Soviets on their accomplishments (McGhee 330)."

Abstract
This paper takes a critical look at the book "Rare Earth: Why Complex Life is Uncommon in the Universe", by Peter Ward and Donald Brownlee. It discusses their theories of the beginning of life on Earth and additional theories to life on other planets. It challenges their research and data and offers other explanations and theories.
From the Paper
"Was the occurrence of complex life on the planet Earth an isolated event or simply the next logical step in evolution? Ward and Brownlee seem to believe complex life is unique to our home world or at least extremely scarce in the Universe.1 In addition to the factors in their Rare Earth equation, mentioned in their book are some specific factors peculiar to Earth that may have affected the development of complex life. Beginning with the planet Mars, W&B argue that the fossil record shows that the cooling Earth developed bacterial life as soon as conditions permitted. They suggest that this may be because the bacteria first developed on Mars, which cooled earlier, and that perhaps Earth was then seeded with these bacteria carried by meteorites reaching our planet after having been ejected from Mars by asteroid impacts. The low gravity of Mars makes this more likely, and it is estimated that ten percent of meteors ejected from Mars may impact Earth. A system lacking a Mars-like planetary companion might have been slower to develop bacterial life."

Abstract
In this paper the plot of the movie directed by Stanley Kubrick and the book written by Arthur C. Clarke are summarized with emphasis on the philosophical and ethical issues presented in the story. A more detailed analysis of the ethical issues, including man becoming god and Hal the computer, concludes the paper. The paper is written from a Christian perspective and relates the story to Biblical examples.
From the paper:
"2001: A Space Odyssey" was written by Arthur C. Clarke and published in 1968 at about the same time as the movie of the same title was released. It is interesting to note that the film and the book were being produced at the same time. Rather than to base one on the other, the movie and the book were made almost as one, with modifications being made to suit the needs of the writer and director. Directed by Stanley Kubrick, the movie was left more open-ended than the book, and tended to draw either praise for its ingenuity or harsh judgment for its dullness and lack of imagination. Whether the first or the latter opinion is correct, one thing is for certain: 2001 is an epic that changed the face of science fiction and paved the way for a whole new way of thinking."

Abstract
This research paper investigates the science of rocketry starting with the original concept, up to the present day space program. Developments in Germany, Russia, and the U.S. are detailed, along with the ways in which rockets have been used both on earth and in space. Most of the paper will deal with the development of the rocket engine up to its present day standards and its history in space flight.
From the paper:
"The notion of flying has fascinated people since the beginning of history, and most likely since the beginning of time. With the development of astronomy, man shifted that dream to another realm: outer space. Robert H. Goddard, a physicist of the early 1900?s, once told a story in his autobiography of how he was inspired to follow the dream of space flight. He recalls once when he was 17 years old; he was trimming branches in a cherry tree, and looked out at the sprawling country landscape. He imagined how fabulous it would be to soar upward into space, watching the earth receding below him. ?I was a different boy when I descended the ladder,? Goddard states, ?Life had now a purpose for me.?

Abstract
This paper describes the life of Galileo Galilea--his childhood, youth and how this affected his chosen path in life. It analyzes his theories as well as the harsh and life threatening criticism he faced from the Church.
From the Paper
Galileo?s father was a musician who eventually challenged Aristotelian beliefs about music theory and who proved some of it wrong, so Galileo grew up in a forward-thinking house where beliefs that had been long-held by educated people were being questioned. His father was part of a small group of musicians who revolutionized the way music was written. These changes led to the birth of opera. He saw his father?s musical experiments, which contradicted the most basic assumptions regarding music theory. These older beliefs were also tied to church theology. It was believed at the time that the rules of harmony paralleled the motion of the heavenly body. This concept was known as the ?music of the spheres.?
