👉 Chart missiles, also known as chart rockets or chart launchers, are simple, low-cost rockets designed for educational purposes to teach principles of rocketry and space exploration. They typically consist of a basic structure with fins for stability and a small payload, often a model rocket or a small satellite. These rockets are launched from the ground and follow a predictable trajectory, allowing users to observe and measure various aspects of rocket flight dynamics such as altitude, speed, and burn time. The simplicity and affordability of chart missiles make them accessible to students, hobbyists, and educators worldwide, fostering interest in STEM fields and providing practical insights into aerospace engineering.
