Jordan Fahringer

Mechanical Engineer Intern

Jordan is an ambitious Mechanical Engineering student attending The University of Florida. She has experience working on numerous projects with UF’s Formula-SAE Gator Motorsports team. This experience gave her the opportunity to learn about real-world engineering while designing with SolidWorks CAD and applying the manufacturing using machine tool equipment such as manual mills and lathes (great engineering comes from hands-on experiences!). While working with this team, Jordan found a passion for motorsports and decided to start a personal project. With the help of her Father, she found a 2006 Mazda MX-5, restored and converted into a track car. Jordan’s dreams lay in the stars, however. When she was 13 years old, Jordan visited NASA’s Kennedy Space Center and was awestruck. Since that day, she has dreamed of working as an engineer in the space industry.
