Abstract
This paper compares the Hubble Space Telescope to its potential successor, the James Webb Space Telescope (JWST), in terms of their cost effectiveness. The paper looks at the technology of both telescopes to see which will bring continue to bring back the most valuable information, their respective missions, the cost of deploying and maintaining them in orbit, and the cost of repairs, if any, of the telescopes to determine the cost effectiveness of the telescopes.
From the Paper
"Ever since its launch in 1990, the Hubble telescope has been orbiting the Earth at 600 kilometers above, bringing valuable information and photos from space. Its history goes back to 1977, when the Congress approved the project funds. However, operations didn't take off until 1981, when the Space Telescope Science Institute was founded, designed especially for the production and research of the Hubble Space Telescope."

Abstract
This paper provides a history of the Hubble Space Telescope. The paper first notes that the Hubble Space Telescope (HST) was named after the astronomer Edwin Hubble and that it is presently in orbit around the Earth, just outside the planet's atmosphere, providing a great advantage over telescopes that are based on the surface. The paper then looks at how the Hubble was launched in 1990 and has grown to be one of the more valuable astronomical instruments in history. In addition, the paper looks at how breakthroughs in astrophysics have been made with the assistance of the increased abilities allowed with the HST.

From the Paper
"In 1983, a struggle for power between NASA and the entire scientific community led to the establishment of the Space Telescope Science Institute (STScI). Run by the Association of Universities for Research in Astronomy (AURA), the STScI is located on the Johns Hopkins University campus in Baltimore, Maryland. The STScI has the primary responsibility of operating the telescope and delivering data to the astronomy community. Engineering support is located nearby, just south of the STScI, in Greenbelt at the GSFC under NASA's management. Since it was launched, the HST operation has been monitored on a twenty-four hour basis, seven days per week by four separate teams of controllers referred to as Hubble's Flight Operations Team (Hubble Space Telescope, 2007)."

Abstract
This paper discusses the Hubble Space Telescope (HST), the first Earth-orbiting reflecting telescope. The paper examines how the Hubble Space Telescope serves a vital function in increasing our knowledge of the universe. The paper explains that since its launch in 1990, despite several crucial problems, it has revealed a universe full of mysterious bodies, nebula, star systems and galaxies and has expanded the possibilities that humankind is not alone in the universe.
From the Paper
"The first scientific idea for a telescope such as the HST came about in 1946 when Lyman Spitzer issued a proposal for a space telescope with a primary mirror between sixteen and fifty feet in diameter. Throughout the 1960's and 1970's, with the ultraviolet observatories OAO-2, OAO 3 and the IUE in the planning stages, the space telescope remained only a dream, due to the lack of technology. Yet Spitzer did not give up, for by the 1970's he had offered another proposal for a space telescope which would be able to provide images of very faint objects as contrasted to ground-based telescopes which suffer from distortion due to the Earth's atmosphere. According to Spitzer, such a telescope would not "supplement our present ideas of the universe we live in, but rather would uncover new phenomena not yet imagined and perhaps would modify profoundly our basic concepts of space and time" (42)."

From the Paper
"The Hubble Space Telescope is a cooperative program of the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) for the operation of a long lived space based observatory for the benefit of the international astronomical community. The idea was first developed in the 1940s, designed and built in the 1970s and 80s, and made operational only in the 1990s. This was to be a different type of mission for NASA, to create a long term space based observatory. In order to accomplish this goal and to protect the spacecraft against instrument and equipment failures, NASA had always planned on regular servicing missions. The Hubble has special grapple fixtures, 76 handholds, and is stabilized in all three axes. The Hubble is a 2.4 meter reflecting telescope which was deployed in low ..."

Abstract
A paper on the development of the telescope by Galileo Galilei. The author discusses the many theories borne from Galileo's observations of the heavens.
From the Paper
"Centuries ago, a tube and two lenses were the only essentials needed to start the journey into the sky. This instrument, called a telescope, expanded the human vision and brought new light from beyond their world and beyond the already visible sky. It allowed mankind to explore the most distant places imaginable without leaving their backyard. Astronomers have studied the stars for centuries, and, with the aid of a telescope, have discovered new entities that exist in the universe. The first person to use this tool for astronomical purposes was Galileo Galilei. He was the first to turn a telescope up into the stars and make observations. His telescope was crude and not as powerful as telescopes today, but it was effective during his time. Although modern telescopes are far more powerful and extremely effective due to electronics, mirrors, and other enhancements to the design of the telescope, the observations and discoveries made by Galileo and his rudimentary telescope are just as significant as those made by telescopes today and in the future."

Abstract
A detailed survey of the planets. The author looks at the space age and how knowledge has developed over time. Includes a detailed discussion of each era from 1957 when the Soviet Union launched Sputnik to the present.
From the Paper
"Think of how exciting it must have been to live in the days when the telescope was first turned to the heavens. Every part of the sky offered a new surprise. The planets were transformed from specs of light to globes with unique characteristics. Could there be a more thrilling time of planetary discovery than those days of Galileo and the first telescopes? Yes, we live in such a time. How could the glimpses those early telescopes gave compare in richness to the dozens upon dozens of photographs and storehouses full of other data collected in the past few decades? Thanks to the spacecraft, we have finally started to know the planets as real places, both like and unlike Earth."

Abstract
This paper addresses the use of public space within the context of the city of Vancouver. In particular, the paper discusses the mixed-use Office Tower in Surrey, Vancouver, British Columbia. While there are many excellent public space projects underway in Vancouver, such as Canada Place, the Art Gallery, the Airport, the Greater Vancouver Regional District Project, and the English Bay, the aforementioned mixed-use office tower designed by Bing Thom is a very interesting glance into how public space offers both the promise of inclusiveness at the same time as it presents the threat of public space slowly becoming overwhelmed by private interests to the exclusion of inclusiveness.

Abstract
This paper discusses the physiological changes to the human body during space travel. Early predictions of the response of humans to spaceflight assumed that space adaptation would be analogous to human disease processes rather than to normal physiology. Through studies of bed-rested healthy adults and medical examinations of crews returning from space, we now recognize the adaptive nature of the responses to spaceflight or its ground-based models. e are also aware of the necessity to minimize the flight-induced changes so that crews maintain their Earth-readiness and avoid injury on landing. Lack of gravitational loading affects multiple physiological systems, especially support structures that are particularly vulnerable to injury during reentry and renewed exposure to gravitational forces. Thus, most crew members exercise extensively during flight. Although many physiological systems appear to be affected by spaceflight, only the cardiovascular, neurovestibular, and musculoskeletal systems are covered in this paper.
The paper includes illustrations.

From the Paper
"As soon as they switch to an internal alignment and use the feet to signal down, they are able to function normally. Upon return to Earth, the brain is confused once again as gravity is now available for orientation. This confusion creates postural instability that is compounded with the cardiovascular difficulty in standing. Also, reflexes associated with posture are slowed even on short-duration missions. With long-duration flights, changes in reflexes may become a major issue."

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)."
