Compare And Contrast Essay On Mars

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. Although Mars is surprisingly similar to Earth, when it comes to size, distance, and temperature,

The atmospheric condition on Earth is amiable and friendly. There are a number of main factors that influence climate including the amount of sunlight, the height above sea level, and the shape of the land, for example. The Earth’s atmosphere consists of 0.038% of Carbon dioxide, 77% of Nitrogen, 1% of Argon, and 21% of Oxygen (Smith, n.d.). The climate on Mars, in contrast, is hostile and unfriendly to life. The temperature on Mars declines to -87 degree Celsius and hardly get higher than 0 degree Celsius (“Mars facts”, n.d.). The major dilemma is that Mars lack of atmosphere (Cain, 2008). The thickness of Earth’s atmosphere is less than 1% (Cain, 2008). Its very thin atmosphere comprises of 95.3% of carbon dioxide, 2.7% of nitrogen, 1.6% of argon, 0.15% of oxygen, and 0.03% of water (“Mars facts,” n.d.). This is not only injurious but also poisonous to breathe and to live. Without ozone layer and little atmosphere, the ultraviolet radiation of the sun has nothing to confine and rays are able to penetrate the atmosphere easily. This is quite harmful to individuals. Therefore, the atmospheric temperature of Mars seems not hospitable and unfriendly toward …show more content…
