Press 1 to launch the rocket from the pad. this will cause the umbilicals should move aside, All engines to ignite and the rocket to detach from the pad.

I recommend having crash damage off and unbreakable joints on for loading physics .Otherwise it will explode.

When launching the Saturn V–> Max thermal should be off to avoid melting the pad or blowing up the launch pad. when you clear the tower you can turn them all off.

I also have indestructible facilities on but i’m not sure if that makes a difference. so keep that in mind

The payload in the fairing is a pre-assembled Mars Base Camp interplanetary ship based of of Lockheed Martins designs. Everything is ready to go except the solar panels which need to be attached with the drone. After which you can destroy the docking ports with the inward engines on the drone.

Note. I have found that in order to use the payload as was intended you pretty much have to change all of the heaviest part auto-strut to grandparent on the payload before you dock anything else with large mass to it (I usually try and alternate between heaviest and grandparent auto-strutting when building so I hope you can semi recognize the pattern). I suggest you F5 before you dock just in case you missed any.
