Apollo 15

ATTENTION! BEFORE YOU BEGIN, YOU MUST KNOW AT LEAST A LITTLE ABOUT HOW THE SATURN 5 ROCKET WORKS, OTHERWISE YOU WON'T UNDERSTAND IT!
You are the commander of the Apollo 15 space program, and to your left is your comrade, James Irwin (he's in the photo). You are now sitting in a Saturn 5 rocket on the launch pad in Houston. The controller has given the command to begin the countdown. There are 10 minutes left until liftoff, and you are starting to check the equipment.

the pyropatrons are reinforced
Fuel sensors are ok, on-board computer is working.

breakaway!
The rocket shot forward, cutting through the air, and a few minutes later the first stage separated.
Using commands, you create an orbit around the Earth. A few minutes later, you manually separate the stage, and with it, your emergency escape system flies off into the vast expanses of space, revealing a view out the windows.
Congratulations, you've reached orbit.
the dispatcher's voice was heard from the radio
Your orbital velocity is 620 km/s, almost the minimum. You separate the command module from the main rocket, precisely rotate the rocket 180°, and then dock with the lander. Applying reverse thrust, you pull the lunar module out of the stage, turn it around again, and rush toward the Moon...
You unbuckle from your seat with relief and begin to levitate around the command module, looking at your comrades.
James: Well, finally... forward to the Moon!
James unbuckled himself and flew inside the landing module, looking at it as if for the first time.
