What Is Rocketry?
Rocketry involves designing, building, launching, and sometimes recovering vehicles that travel through the Earth's atmosphere or into space. These vehicles, known as rockets, are propelled by the expulsion of exhaust gases from a rocket engine. Unlike airplanes, rockets are not reliant on the air around them for lift and can operate in the vacuum of space.
- Rockets have been used for fireworks and military uses for centuries, long before they were considered for space exploration.
The Evolution of Rocketry
