Mars Essay

Amazing Essays
Mars have always been perceived as a desolate planet, which does not have anything special other than arid surface with scattered rocks and mountains. However, science is telling us that this perception could be far from reality. With the rapid development of scientific research, paralleled with the technological revolution, recent explorations have revealed new data and interesting findings on the surface of our mysterious neighbor. Galileo Galilei was the first man to use a telescope to observe the Red Planet (UCL, 1999). However, it was not until the late 18th century when scientists mapped and documented detailed observations of the planets` atmosphere, clouds, polar ice caps, and rotational orbit periods (UCL, 1999). In the late 18th century …show more content…
Similar to other terrestrial planets Martian surface has been changed by volcanism, impacts from other bodies, movements of its crust, and atmospheric effects such as dust storms (National Geographic, 2014).

The atmosphere of Mars resembles a thin layer surrounds the planet and consisted of 95% carbon and less than 1% Oxygen (NASA, 2015). The habitability of planets requires its atmosphere to conserve temperature and provide warmth for organisms to grow and protects the planet from radiation. Unlike Earth atmosphere and due to Mars weak gravity, Martian atmosphere is thin and majority of gases are easily blown away in space therefore the remaining thin layer fails to protect the surface from radiation and space object impacting the Red Planet`s surface (Cosmic Diary,

Like Earth this impacts the temperature seasonal variation on Mars, which is another aspect that scientists focus on when studying the mysterious red neighbor. NASA studied this impact on the decreasing volume of the ice caps around the poles, and predicted the volume of water loss through time until it reached its current volume today. As the cap shrinks it develops rifts, dark spots, and a ragged border. As NASA describes (2003) ice caps are made of frozen Carbon Dioxide, which is the primary component of Mars atmosphere. With the change of seasons, the height of carbon dioxide changes in turn, thus it becomes lower during cold season and rises to atmosphere during warm season. NASA continues its research on Ice caps as potential locations where water was trapped (NASA,

    With an average temperature of 864 degrees Fahrenheit, it is about fifteen times hotter than Earth. Not only that, but the harsh condition of its atmosphere which is ninety-two that of Earth, and full of sulfuric acid and carbon dioxide, make human life virtually impossible. However, some researchers believe some sort of life may be somehow possible. The surface of Venus is extremely dry, according to radar maps, but there is a possibility of small sulfur lakes and rivers so shallow, they have been missed. If there was life on Venus, it would definitely not be humans.…

    Most of the water on Mars forms permafrost which coats the planet’s surface (Exploring Life’s Mysteries). Scientists have recently found liquid water on Mars, but it is mars atmosphere that creates a problem for intelligent life to live on the planet. Mars atmosphere severely lacks oxygen. Mars’ atmosphere contains ninety-five percent carbon dioxide, three percent nitrogen, and one and six-tenths percent argon (Exploring Life’s Mysteries). It has significantly lower pressure than Earth has.…

    The holes in our ozone layer are unprotected spots on Earth which expose us to the foreign substances of space. Antarctica is a large ice dome over land, and the ice is starting to melt because of the radiation and heat being let in by the hole in the ozone layer (Sigmond & Fyfe,…

    Mars and Earth: Same Same but Different "We know how much radiation is out there, waiting for us between Earth and Mars, but we’re not sure how the human body is going to react to it" says Frank Cucinotta, Space radiation health project of NASA (Burgess & Dubbs, 2007). A new adventure comes along when there is no other giant planet and limited space to block during a long voyage to Mars. Mars has always been the final destination that many scientists turn to in terms of colonization of other planets. This is because Mars is similar to Earth. Many of the same physical features, such as geology, that people recognize on Earth also exist on Mars.…

    Liquid water flows according to NASA, appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times”. Hydrated salts lowered the freezing point of the water essentially creating brine making it possible for water to flow on the surface of Mars. Future Mars missions could greatly benefit from this discovery with a source of water confirmed on Mars, we can collect it for studying and eventually consumption. Once we have examined the Brine and determined it safe for human consumption, we can begin a desalination process to create drinking water. By tapping into this water source we would no longer have to drink so much water for a single mission, which would lower the payload weight at launch ultimately saving money for other…

    For all of the sunlight that earth absorbs, an equal amount of infrared radiation must travel from the earth back to space. If this process did not happen, there would be no global warming or global cooling in the atmosphere. The greenhouse effect refers to short wavelengths of the visible light spectrum, from the sun, to pass through a transparent medium, but longer wavelengths such as infrared radiations are not able to pass. Infrared radiation plays a major role in global warming. Global warming is produced by the trapping of the rays in earth’s atmosphere by the rising of carbon dioxide, which causes the excessive heating.…

    The environment can change if there is a change in the amount of solar energy that gets to the Earth. Volcano eruption can genuinely affect climate because when it erupts, it spews out more than just lava and ash. Volcanoes release tiny particles made of sulfur dioxide into the environment. These particles get into the stratosphere and reflect solar radiation back out to space. Snow and ice likewise significantly affect the atmosphere.…

    Moon: Theia Impact or “Big Splash” Theory: When in Earth was still in a molten state, an impactor (Theia) collided with the still forming Earth. Debris and magma that separated from the original body is believed to have congregated and formed into our moon, remaining in its “parent’s” orbit. (Most Plausible Explanation) Fission Theory: Chunk of magma separated from Earth in early formation stages. Pacific ocean basin is said to be where material was removed. Capture Theory: The moon was formed elsewhere and was pulled into Earth’s field of gravity.The moon is 4.5 billion years old.…

    Global warming is the increasing of the earth’s surface temperature. Green house gases as mentioned earlier are those that contribute to the greenhouse affect. An overall warming of the earth as atmospheric gases trap electromagnetic radiation that should have been radiated back into space. These gases are thought to affect climate change even though they make up such a small amount of the atmosphere they play a large role. In summary climate change is referring to changes brought about by different factors one of these factors is the greenhouse affect, which cause shifts in global warming, and in term changes the overall…

    Solar Winds and the Martian Atmosphere The suns steadily releases charged particles from its upper atmosphere through the Solar System by solar winds. These winds have different effects depending on the properties of the planet. Earth, for example, has a very strong magnetic field as a result of a multitude of factors. Mars on the other hand does not have a strong magnetic field protecting it from the solar winds. It is believed that Ancient Mars had rivers and lakes, however it died billions of years ago after the bombardment of solar winds eventually depleted the atmosphere to create the version of mars that we know of today.…
