Tricia Hevers, an aerospace engineer, describes the significance of satellites, what it takes to launch them, and the missions that small satellites can perform, in this video from WGBH and The Documentary Group. She describes her interest from a young age in aerospace engineering and her role model, female astronaut Eileen Collins. In her job, Hevers uses complex mathematics to ensure that the satellite is pointed in the right direction. She also helps facilitate communications on her team. Looking toward the future, she says that small satellites will do everything, from creating the next GPS constellation to performing satellite-to-satellite repair services.
