Free online courseRocket Science for Everyone

Course Description

Rocket Science for Everyone is a free online astronomy course from Yale Courses that makes spaceflight concepts approachable for curious learners and hobbyists. It connects everyday technology to the physics that makes rockets, satellites, and space missions possible, helping you build intuition without needing an advanced technical background.

You will explore what an orbit is, where space begins, and how Earths orbital neighborhoods work, including low, medium, and geostationary orbits. Along the way, you will learn how to compare orbital paths and understand why satellites behave differently depending on altitude and trajectory, including polar coverage and the role of speed in staying in orbit.

The course also breaks down the core laws of motion that explain how rockets fly and why aircraft cannot simply climb into space. You will dive into key propulsion ideas such as solid and advanced rocket types, the rocket equation and its implications for fuel and design, and why multistage rockets are used to reach higher speeds and farther destinations.

To round out the big picture, you will examine what satellites carry and how they function, from payloads and solar power to radio communication and imaging systems that support everything from scientific discovery to tools you use every day. Real mission context and launch considerations help tie the physics to practical outcomes, showing how teams plan, build, and operate spacecraft from launch to operations.
