You will begin your journey to the far side of the moon by first launching aboard a Soyuz spacecraft.  Then, a subsequent launch will occur of an unmanned rocket booster.  Your spacecraft will rendezvous with this additional system in low-Earth-orbit.  The engagement of the two will provide your spacecraft with the required propellant to travel to the moon.  Once the firing of the booster is complete, the two systems will separate and you will continue on your majestic journey.
