Comparison Essay Final Draft

Barely have we broken the Earthly bonds that keep us here and conceal us from the stars above. Currently we do not have plans to touch down a human on the nearest planet till 2025. However until then, I find it very necessary to really take into consideration the places we can consider as options. Some may find such a venture forward like this a waste of taxpayer money, but when it comes to the advancement of our society as a whole, especially for survival’s sake, we must treat such research as critically and sensitive as possible. Many factors must be looked at such an investment for humankind happens. Travel and distance between the planet and Earth must be reasonable, the characteristics of the planet itself must be complementary to our own survival in some form, and finally it must show a significant worth in the investment of us as a species. Although as difficult of a combination as these may be, thankfully there are such places within our solar system. Our planetary neighbor and Saturn’s largest moon have both shown such promise. Therefore, with the need of expansion into our own galactic neighborhood a necessity, we must compare two of the most highly considered worlds outside our own, Mars and Titan, for exploration. Dubbed to be just outside our solar systems’ habitable zone, Mars would be an excellent first stop for the colonization of humanity somewhere other than Earth. Considering it’s the closest object in the sky next to our moon and Venus, it has an average distance between our two planets of 140 million miles (225 million km), thus it would take 3,888 hours (162 days) with a ship travelling 36,000 mph (58,000 , kph) to reach. This may seem far, however considering our second home would be moving near and away from us constantly, it would be decently easy compared to anywhere else. With the little exploration of the planet we have already conducted, we have already come to discover much about what this planet has had to offer. In fact already we have come to realize just how alike Mars is from Earth. Of all the planets in the Solar System, the seasons of Mars are the most Earth-like, due to the similar tilts of the two planets' rotational axes. The lengths of the Martian seasons are about twice those of Earth's because Mars' greater distance from the Sun leads to the Martian year being about two Earth years long. Other features that exist show clues that once the Red Planet was covered in large bodies of water, this proven by the largely geographic landscapes it has. Mountains, riverbeds, canals and landforms visible on Mars strongly suggest that liquid water has, at least at times, existed on the planet's surface. But due to recent studies any liquid water on the surface of Mars as of now, would instantly burn up, due to the thin atmosphere of the planet. Some might although suggest that the water is trapped in the planets’ north and south polar ice caps due to the presence of ice, which during the winter months the poles are darkened by lack of sunlight. But unfortunately this ice is never a liquid at all. For instead its composition comes straight from the atmosphere and freezes to make dry ice, or frozen CO2. Nonetheless scientists are determined to dig into the iron oxidized planet, and hopefully discover the conceived idea that this dead planet could have been once as fertile as ours. Being so alike with our own planet, Mars offers a perfect example of humanity’s first possible attempt of colonization and with signs of liquid water, this could be the closest to another home we will have in our solar system If the rustic red barrens of Mars aren’t exactly what you’re looking for then try travelling to Saturn’s largest moon, Titan. Considering Saturn is the sixth planet from the sun at a distance of about 1.5 billion km (934 million mi), it would take 6 ½ years of travel to reach the small satellite. That’s a long trip to reach a moon, so why go there? Titan is probably the best example of
