payload click to hear : payload

Includes the Apollo craft, the lunar module and the third stage; the latter, after being placed in Earth’s orbit, soars toward the Moon.

third stage click to hear : third stage

At an altitude of 148 km, the third-stage engine begins to run, allowing the launcher to place itself in orbit before making its way toward the Moon.

second stage click to hear : second stage

At an altitude of 62.5 km, the five second-stage engines ignite, burning for 6 min. 30 sec. before they are jettisoned.

first stage click to hear : first stage

Equipped with five F-1 engines that give the launcher the thrust it needs to leave the launchpad; jettisoned after 2 min. 30 sec. of flight.

F-1 engine click to hear : F-1 engine

The first stage is equipped with five; it provides thrust using kerosene-liquid oxygen combustion.

nozzle click to hear : nozzle

The end portion of a rocket from which combustion gases escape, thereby creating the thrust needed to propel the craft.

stabilizing fin click to hear : stabilizing fin

Fins located on either side of the launcher, serving to stabilize it.

fuel transfer pipe click to hear : fuel transfer pipe

Pipe through which liquid oxygen is sent to the rocket engines.

kerosene tank click to hear : kerosene tank

Kerosene, burned on contact with liquid oxygen, serves as fuel for F-1 engines.

liquid oxygen tank baffle click to hear : liquid oxygen tank baffle

Serves to limit the movement of liquid oxygen inside the tank.

liquid oxygen tank click to hear : liquid oxygen tank

Contains liquid oxygen used to burn kerosene.

liquid hydrogen tank click to hear : liquid hydrogen tank

Hydrogen, burned on contact with liquid oxygen, serves as engine fuel.

J-2 engine click to hear : J-2 engine

The second and third stages are equipped with J-2 engines; these provide thrust using liquid oxygen-hydrogen combustion.

helium sphere click to hear : helium sphere

Helium is used to pressurize the oxygen tank.

instrument unit click to hear : instrument unit

The brain of the rocket; includes the computers and all of the electronic equipment that controls the rocket during its launch.

lunar module click to hear : lunar module

Inhabited section of the craft; enabled two men to walk on the Moon and spend a few days there before returning to dock with the Apollo capsule.

service module click to hear : service module

Houses the main propulsion system and supplies energy, electricity, water and other provisions.

command module click to hear : command module

Capsule inhabited by the crew during most of an Apollo mission; the only part of the vehicle to return to Earth.

launch escape system click to hear : launch escape system

Makes it possible, in the event of damage, to separate the command module from the rest of the launcher and to pull it.
