Three parts of a rocket
• The structural and mechanical elements are everything from the rocket itself to engines, storage tanks, and the fins on the outside that help guide the rocket during its flight. • The fuel can be any number of materials, including liquid oxygen, gasoline, and liquid hydrogen. The mixture is ignited in a combustion chamber, causing the gases to escape as exhaust out of the nozzle. • The payload refers to the materials needed for the flight, including crew cabins, food, water, air, and people.
