The first stage (labeled S-IC), held five enormous F-1 engines that produced a total of 7.5 million pounds of thrust.
Stage one burned for only 2.5 minutes, accelerating the spacecraft to a speed of approximately 6000 miles per hour.
The second stage (labeled S-II), used five large J-2 engines which burned for approximately six minutes, taking the spacecraft
to a speed of 15,300 miles per hour and an altitude of about 115 miles.
The third stage (labeled S-IVB), fired last putting the spacecraft into orbit.
Stage 3 contained only one J-2 engine which could be restarted in order to begin the flight toward the moon.
