Rocket science is the study of how to design and build rockets and spacecraft. It involves understanding the principles of physics and engineering to create vehicles that can travel beyond Earth's atmosphere. This field focuses on propulsion systems, aerodynamics, and materials that can withstand extreme conditions in space. The term "rocket science" is often used colloquially to describe something that is very complex or difficult to understand. However, in reality, it encompasses various disciplines, including aerospace engineering, mechanics, and thermodynamics, all working together to enable space exploration and satellite deployment.
