Abstract
The paper details the similarities between Earth and Mars explaining that Mars once had its own water cycle. The paper explains what an asteroid is and asserts that asteroids probably destroyed Mars. It speculates whether an asteroid can destroy Earth and discusses ways to prevent this from happening.
From the Paper
"A billion or so years ago, a frozen lake covered the plains that were alive. Most of the other volcanoes had stopped spewing gases, the temperature and atmospheric pressure on Mars were so low that ice from the lake surface sublimated. These formed into vapor without melting as water. The water vapor formed clouds that dropped snow onto the volcano?s slopes. The volcano?s magma chamber warmed the slopes enough to melt the bottom layers of the deep snow pack."

Abstract
In this article, the writer notes that the solar system is a unique combination of many different types of planets, which has many different things that it can offer to humans. However, the the writer points out, planet Earth offers the most beneficial climate and diversity for human life. The writer notes that many of the other planets are entirely devoid of life. The writer discusses that despite the fact that there are eight planets in our solar system, only Mars (other than Earth) seems to be capable of containing human life at all. The writer maintains that Mars has many of the requisites that are needed to sustain human life, such as the possibility of water, small amounts of oxygen, and a possibility of life. The writer concludes that if humans were to ever colonize another planet in the solar system, Mars would be the most intelligent choice.
From the Paper
"Apart from the cold at its poles (which is far more extreme than Earth's), Mercury shares very little in common with Earth. It would be very difficult for humans to inhabit Mercury. The temperature extremes, the lack of water, and the lack of a protective atmosphere would quickly decimate human life attempting to live there. Current space craft could succeed in landing humans on Mercury, but it is unlikely that there would be a way to maintain proper oxygen levels for survival.
"Venus is another planet that is very inhospitable. Yet, for several reasons, it is known as the sister planet to Earth: Venus is similar to Earth's size (95% its diameter, 80% of its mass. Both planets do not have many craters, which points to young surfaces."

Abstract
Of all the planets in our solar system, Mars has long seemed to be the most habitable besides Earth. Many scientists believe Mars may have had oceans of water, a warmer climate, and rich vegetation billions of years ago. This paper examines the hazards that inhabitants would face if Mars was to be made habitable again and some of the solutions that scientists are working on to reduce problems of living on the Red Planet.
From the Paper
"Mars' atmosphere is so thin, there is little protection from the ultraviolet radiation from the Sun, and this would pose yet another hazard to anyone who wanted to live on the planet. Anyone living on the planet would have to be protected from the constant radiation by either a space suit, or living inside a protective habitat. Clearly, colonizing Mars would be an extremely expensive endeavor, and until the first person actually steps on the planet, it is impossible to tell exactly what the conditions are like, and what threats they pose."

Conclusion
From the Paper
"These space probes and explorations about Mars brought about numerous information and even pictures of the planet?s surface. However, it is difficult to obtain quality shots of the planet?s surface because of its distance from the Earth, and accuracy and precision was sacrificed when information brought by these probes came into existence and knowledge of scientists and astronomers. One speculation that resulted from these studies and explorations is that aside from the possibility that Mars is capable of cultivating human life, there has been evidence supporting some scientists? claim that there existed a form of civilization in Mars."

Abstract
This paper is a discussion and analysis of the environmental issues that are discussed in Mark Hersgaard's book, "Earth Odyssey." Some of the topics examined are nuclear technology, humanity's addiction to the automobile, the health of the planet and the affects of unbounded capitalism. The author also discusses poverty, and some of the reasons for the disparities between the richer and poorer countries and their populations. The author also poses several solutions to some of these problems.
From the Paper
"But Hertsgaard also brings up other ways we are destroying our environment, that beyond our own selves. According to Hertsgaard, ?the automobile may well be the ultimate symbol of the modern environmental crisis? (p.90) The world?s fleet of cars contributes ? between 20 and 25 percent of current greenhouse gas emissions; only electric power plants, with 25 percent, and deforestation, with 25 percent, are as damaging.? (p.94) And then there?s health effects: ?A study released by Harvard University researchers in 1995 found that 30,000 Americans die every year from respiratory illnesses related to car exhaust, while another 12,000 people die prematurely because of such exhaust? (p.95) Clearly, this is a point in his argument he feels especially strong about. And more importantly, it?s one we as a population can control."

Summary
From the Paper
"On December 4, 1996 the pathfinder mission was launched on a Delta II-7925 launch vehicle out of Cape Canaveral Air Station. After 211 days in space and a distance traveled of almost 300 million miles the spacecraft landed on July 4, 1997 at its destination (DLR, 2003). In order to fine-tune the flight path a series of four-trajectory correction maneuvers (TCMs) were performed throughout the journey. NASA used the Deep Space Network (DSN) for tracking, telemetry, and command operations. DSN is an international network of antennas that supports interplanetary spacecraft missions by using giant dish antennas (Jet Propulsion Laboratory, 2004)."

Abstract
The paper discusses the Red Planet which has fascinated astronomers from early days. The paper states that as we began more missions to Mars we gained a greater understanding of our solar system. President George W. Bush has announced plans to send humans to Mars. The paper discusses the various missions to the planet and the possibility of living on Mars. The paper states that if we look into the future, we will see that soon we will run out of resources, and will be forced to stray from earth in order to survive. The paper further suggests that the best way to do this would be to colonize Mars as an important aspect of our survival, and we should now start to take steps toward a new frontier of life, off into the vast extreme of space.
From the Paper
"The cost to send manned missions will be much higher than any ever before perceived, but we will soon find out that these missions will become necessary parts of the survival of our species. If we really want to get our money's worth, we must send humans to Mars instead of just robots. Robots can only do so much. For example, a robot must collect data, send it back to Earth, be analyzed by a team of scientists twenty minutes later, then receive the information regarding the path it should take for the next five feet another twenty minutes later. Thankfully, we do not need to be so meticulous in navigating the humans we send to Mars. These people can find their own way around, without the help or need of a computer, or a team of expert scientists twenty light minutes away. With a working system of spacecraft, we would be able to ferry people from planet to planet, always keeping a group of people on Mars. This way we could always be working there, not just a chunk of three months every two years. In this manner, manned missions to Mars would prove to be much more effective than the alternative of robotic missions conducting experiments for limited amounts of time. We shouldn't necessarily be concerned with the effects of ourselves on the planet, but with the effects of ourselves on our own species."

Abstract
This paper explains that the Snowball Hypothesis for Earth, which is a theory speculating that the earth has experienced consistent cyclical hot and cold periods, can be considered a possible cause of the current trends toward warmer climates and rising seas. The author points out that the theory encompasses tropical sea-level glaciers, distributions of continents, carbon dioxide levels, solar input, banded iron formations and early bacterial life. The paper states that scientist speculate that approximately twenty thousand years ago, our deep ocean waters moved towards the freezing point, but those water temperatures were not near the equator as was the case during the Neoproterozoic period.
From the Paper
"As we currently fear global warming, evidence may be pointing to eventual temperature shifts that follow the Yin and Yang of life. First, there are opposites hot and cold. The planet is merely going through its normal cyclical changes so we should not fear global warming any more than we should expect it as we should also expect another future snowball. "For the last million years, the Earth has been in its coldest state since the Neoproterozoic. We are now living in a relatively warm episode, some 80,000 years from the next glacial maximum, but some evidence suggests that each successive glaciation over the last several cycles has been getting stronger and stronger.""

From the Paper
"Mars, Ares, Tiw, the god of war; the red planet has been revered as the bringer or bloodshed with its red color in the sky, like the color of blood. The planet adjacent to Earth has been an object of mystery and wonder from the time the first human turned his head skyward, to the time when the first telescope was used to observe Mars and its mysterious "canals," to the present day, as humans continue to send spacecraft to the red planet to expand on existing knowledge."

Abstract
This six-page graduate-level paper examines and analyzes manned missions to Mars, and concludes that sending human crews to explore our neighboring planet would not be a wise choice at this time. There are better alternatives, such as establishing a commercial presence in near-earth orbit and the Moon, and exploring Mars with unmanned probes.

Abstract
This essay looks at why life forms on Earth can live on the Earth but cannot survive on other planets. In exploring this fact, this essay discusses scientific theories about the creation of the universe, how conditions on Earth support life, and how the conditions on other planets are hostile to it.
From the Paper
"The current scientific theory about the creation of the universe states that at one time all the matter and energy in the universe was condensed in a very small and infinitely hot mass. About 10 and 15 billion years ago, a huge explosion, termed the ?Big Bang,? took place that sent matter and energy expanding in all directions, and the universe was born. The formation of the stars (including our sun), the galaxies, and the planets are all explained by the Big Bang theory. This hypothesis about the creation of the universe was developed following the observation by an American astronomer, Edwin Hubble, in the late 1920s that distant stars and galaxies are receding from Earth in every direction?indicating that the universe was expanding."

Abstract
This paper is about the creation of the universe, and more particularly about the earth and its early development. To date, no conclusive answer has been drawn about the events of 10-20 billion years ago when the universe came into existence. The whole idea of the 'big bang' is still a matter of debate for scholars, and this paper will attempt to do no more than touch on some of the commonly held ideas about the origins of the universe and the earth. The paper will discuss a few of the events that followed the creation of the universe and the earth, and to explain events as they are currently understood. The format of the paper will be as follows: first, it will discuss the formation of the universe; second, the earth in some detail, looking at the creation of the oceans and the atmosphere; third, it will conclude with an overview of the topic at hand.

From the Paper
"Earth Science is particularly complicated in relation to instruction in the contemporary classroom. This is because of the many political and social issues involved in this area of study which, in the eyes of many, is an area of religious import as well. Furthermore, the initiative to teach in an inquiry-based manner further expands the research and examination in relation to providing instruction in Earth Science. When considering a method of instruction it is critical to take into account the grade-level appropriateness in relation to the curriculum and inclusive classroom activities when planning the instructional lessons and accompanying activities."

Abstract
The paper looks at the Viking landing missions on Mars twenty years ago and their tests for biological processes on the Martian surface. It looks at how a recent series of orbiting Martian missions has yielded a good deal of chemical and geographic observations from afar. The most exciting possibilities have come from the analysis and interpretation of Martian surface formations seen by these missions. The paper includes a detailed description of these formations such as outflow channels, seepage gullies and several others. In further searches for definitive findings, several missions in the near future will land on Mars and hopefully provide the best data yet. This paper details some of the discoveries made to date, the strongest arguments for water on Mars and what the future holds for Martian exploration.
From the Paper
"The thought of life on Mars has intrigued humans for centuries. As Martian astronomy has made incredible leaps in the past 100 years and many spectacular discoveries have been made, we are still not sure if life does or has ever existed on Mars. Over the last thirty years, as our knowledge of biological functions has increased, scientists have focused more and more on the existence of liquid water as the biggest single indicator of possible life. To that end, much work and controversy has surrounded man?s efforts to find evidence of that all important ingredient for the development of life on Mars."
