Sending humans to Mars has long been scientists' dream. This has never been done before. NASA is building a rocket to go to Mars. NASA is an organization in the USA that carries out space programmes. They are now building a rocket called Space Launch System. A company called Boeing, which builds airplanes and spaceships, is helping. Tiera Fletcher is an engineer working at Boeing. She is working on Space Launch System. It will be the largest rocket ever built.
Question one: What was your life like growing up?
Fletcher: I grew up in a small town called Mableton. It is right outside Atanta, Gicorgia. I was very interested in maths as a kid. My mum would take me on trips to the store. She would make me calculate the price of the things we bought. Later, my interests grew. I wanted to be a mathematician. I also wanted to be an inventor and scientist.
Question two: What is aerospace engineering, and how did you become interested in it?
Fletcher: Engineers solve problems. They do so by making products, such as machines. Aerospace engineers work with airplanes and spaceships. I took part in a school programme at age 11. It was about aerospace engineering. I decided that I wanted to become an aerospace engineer. In high school, I studied reverse thrust. Thrust is a pushing force (力). It moves airplanes forward. Engines(引擎) create thrust to push a lot of air backward. This causes the plane to move forward. Reverse thrust is a system. It is used in planes. It changes the direction that the air is pushed from the engine.
Question three: How did you come to work at Boeing, and what do you do there now?
Fletcher: I worked as an intern(实习生) at Boeing. Later, the company offered me a job. Today, I work on Space Launch System. I design some of its parts. The rocket is being built and tested now. It will be the largest rocket ever created. Its goal is to send people to Mars.
Question four: What challenges do you face at work and what have you done with them?
Fletcher: I'm 25, an African American and female. Most of the people I work with are older males. This has been a challenge. People may have unfair or negative(消极的) beliefs about me. I have been able to rise above this challenge. I work hard to prove that I can do my job well. It takes confidence and courage.
Question five: What advice do you have for students who might be interested in a career like yours?
Fletcher: Do your research! Also, keep an open mind. There are so many choices out there in science, technology, engineering and maths. Try them all out. Keep trying new subjects until you find what you love. Do not limit yourself! You are capable(能干的) of more, you can do more, and you can be more.
