My Defining Motivations
​
Four years ago, I read a scientifically in depth article about how Elon Musk planned for SpaceX to get to Mars. The article went way over my head using terminology I didn't know at the time, but I was nonetheless captivated by the general engineering concepts enough to decide that 1: I am going to get to Mars one day, and 2: I will have an impact on the propulsion system that gets us there.
Since I read that article, rocket propulsion has been my passion. I've completed various projects that taught and continue to teach me about engineering, leadership, problem solving, planning, efficiency, failure, willpower, and grit. I'm developing these qualities in my pursuit to gain the experience and knowledge necessary to become a high quality engineer capable of designing an engine powerful enough, safe enough, and efficient enough to carry humans to and from Mars.
​
Outside of my work in rocket propulsion engineering and aerospace classwork, I spend my time improving myself physically and mentally. Since I plan to one day be one of the first people on Mars, I expect to experience intense challenges on the road to getting there as well as once I arrive. I will be required to solve problems that will determine the life and death of myself and others. By preparing myself mentally and physically now, I will be ready to handle the pressure and solve complex problems in intense situations.
