Rocket design involves creating vehicles that can travel into space. Engineers focus on various factors, including aerodynamics, propulsion, and materials. The goal is to ensure that rockets can withstand the harsh conditions of launch and space travel while carrying payloads like satellites or astronauts. Key components of rocket design include the propulsion system, which provides thrust, and the aerofoil shape, which helps reduce air resistance. Additionally, designers must consider the rocket's stability and control systems to ensure it follows the correct trajectory. Overall, effective rocket design is crucial for successful space missions.
