Living on a different planet, particularly Mars, has rapidly become a popular topic of discussion in the science field. While the thought of expanding human civilization to new horizons may be intriguing, the idea may not be as ideal as many people portray it to be. In an interview with Quartz Media, former NASA astronaut Ron Garan explains how people should not abandon life on Earth in order to establish new homes on Mars. In his argument, Garan effectively convey's his point through scientific logical reasoning as well as appealing to the emotions of all human beings.
As a winner of the NASA Exceptional Service medal and the NASA Space Flight medial, Garan is considered to be one of the most qualified space astronaut in the world. While he has already established his credibility through his years of experience out in space, he still gives scientific rational as to why life on Mars is not ideal. When asked why Garan believes humans should not colonize Mars, he answers, "if we can't even "terraform" - which is to control our climate and environment - our own planet, what makes us think that we can go to another planet and control the environment there?". Although Garan provides scientific reasoning behind his claim, he also gives insight as to what "terraform" is, which allows the audience to not only be informed, but believe in Garan's stance. While he does provide logical reasoning through his experiences as an astronaut, he also explains what he wants to convey in order to make his argument more appealing to all people, even if they are interested in space programs or not.
To continue his point on the flaws of permanently settling in Mars, he appeals to the human emotions that is universally felt by everyone. While many people romanticize the idea of living out in another section in the solar system, Garan warns, "There are a lot of things that define beauty of life on oiur planet, like the breeze in your face, mist on a lake, and the sound of the birds. If you're going to live on Mars, your're not gonna have that for the rest of your life". As an astronaut himself, he has the first hand experience of the feeling of isolation in outer space. He opens the eyes of many people by sharing his years of spending time out in space, depiciting the less-than-ideal life on a different planet. By revealing the true beauties of planet Earth, and the numerous hardships that hopeful martians may endure, Garan effectively proves his claim.
Hence, by sharing his first hand experience as an astronaut to the world with the inclusion of scientific rational and appealing to pathos, Garan reveals as to why colonization of Mar is less than ideal to humans living on Earth.
