Liftoff• The first stage’s is five F-1 rocket engines ignite
and produce 7.5 million pounds of thrust.
First Stage Separation
At an altitude of 42 miles the F-1 engines shut down. Explosive bolts fire, and the severed first stage falls into the Atlantic Ocean.
Interstage Separation
• The second stage’s J-2 engines ignite, and the interstage skirt drops away.
Escape Tower Jettison
• Useful only up to about 19 miles altitude, the launch escape tower is now dead weight and is discarded.
Second Stage Separation
• The third stage’s single J-2 ignites about ten seconds after the second stage is cut loose.
Third Stage Shutdown
• At engine cutoff, the Apollo spacecraft has reached a speed of 17,432 miles per hour and is in orbit around Earth at an altitude of 118.8 miles.
Trans-Lunar Injection
• The third stage’s J-2 engine is fired again to break out of Earth orbit and send the vehicle toward the moon.
Lunar Module Extraction
• Now on course for the moon, Apollo separates, turns 180 degrees and pulls the lunar module from atop the third stage. Its job finished, the Saturn stage coasts away into space.
