Go to the room marked as "Launch Dome", which can be found to the right of the Omnitool socket. Get inside, use the tool to close the hatch behind you and continue on.

You must maneuver with the X mark - the proper placement is signaled by change in color (from orange to green).

Go outside and take a turn to the "first right", after which you have climb up the ramp. Place the Omnitool in the socket and take a seat. You now have to complete the last puzzle in the game - you must transfer the ARK to the launcher. Wait for the system to start and back to work.

You must maneuver the crane properly. Aim the orange "X" so that it is positioned directly above the bullet containing the ARK - the X will change the color to green. Press the interaction button, and when the crane picks up the ARK transport it back to the launcher, finalizing everything by pressing the interaction button again. The bullet will be loaded into the launcher. Wait until Catherine finishes talking and press the "Launch" button to fire the rocket.
