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
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
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
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
The first stage is equipped with five; it provides thrust using kerosene-liquid oxygen combustion.
nozzle
The end portion of a rocket from which combustion gases escape, thereby creating the thrust needed to propel the craft.
stabilizing fin
Fins located on either side of the launcher, serving to stabilize it.
service module
Houses the main propulsion system and supplies energy, electricity, water and other provisions.
Apollo
command module
Capsule inhabited by the crew during most of an Apollo mission; the only part of the vehicle to return to Earth.
Apollo
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.
