A model rocket has an aerodynamic nose cap, one stage, solid fuel motor, payload, parachute and stabilizing fins. A model rocket does not have a rocket engine, interstage, fuel tank, oxidizer tank or avionics.
This is where the stats will go. The stats will go here.
The sixth Saturn V, launched on July 16, 1969, resulted in the first manned lunar landing. Astronauts Neil A. Armstrong and Edwin E. Aldrin Jr. made the first human footprints on the moon on July 20, 1969.
A Saturn V rocket has a rocket engine, three stages, a solid fuel motor, two interstages, a payload, a parachute, an aerodynamic nose cap, avionics, a fuel tank, an oxidizer tank and stabilizing fins.

The Black Brant rocket motor is the most frequently used of the NASA sounding rockets.
A sounding rocket has two stages, a solid fuel motor, one interstage, a payload, a parachute, an aerodynamic nose cap, avionics and stabilizing fins . A sounding rocket does not have a fuel tank, an oxidizer tank or a rocket engine.

Rocket Parts Definitions
Aerodynamic nose cap - The top part of the rocket designed for flight in the atmosphere.
Avionics - The electrical systems that control the rocket during flight.
Fuel tank - The tank containing chemicals that combine with an oxidizer to burn and produce thrust.
Interstage - Section that connects stages.
Oxidizer tank - A tank containing oxygen compounds that permit rocket fuel to burn both in the atmosphere and in the vacuum of space.
Parachute - A folding, umbrella-like fabric device with cords supporting a harness or straps that decreases the terminal velocity of an object by increasing the drag on the object.
Payload - The cargo carried by a rocket.
Rocket engine - A machine with moving parts that converts stored propellant into hot gases to produce thrust.
Solid fuel motor - A simple device that converts stored propellant into hot gases to produce thrust.
Stabilizing fins - Lengthwise fixed attachments to rockets to provide a stabilizing effect.
Stage - Two or more rockets stacked on top of each other to reach higher altitudes or have a greater payload capacity.
