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 William Herschel was first to introduce the idea of possible existence of life on the red planet comparing similarities between Earth and Mars in terms of axis tilt angles, rotational periods around the sun, and growth and shrink of polar ice caps leading to seasonal climatic variation (UCL, 1999). Today, the latest findings from NASA 's Mars Reconnaissance Orbiter (MRO) provided the strongest evidence yet that liquid water flows intermittently on present-day Mars (NASA, 2015), Astronomers continue their research with expectations to have solid evidence that life existed or can exist on the Red Planet. The following is an overview and discussion of Mars surface geology and chemical structure, and its atmospheric conditions, and…
