*The heart of the U.S.S. Enterprise is the Main Engineering control center. This point deep within the ship's secondary hull serves as a master control for the ship's warp propulsion system, impulse propulsion system and power generation for the entire ship. Main Engineering can also function as a backup control center in the event of damage or loss of the Main Bridge and the Battle Bridge. At the center of this area is the matter/antimatter reaction assembly (M/ARA) -- the main engine core of the ship that initiates and controls the violent forces resulting from the collision of positive and negative matter. Main Engineering also provides facilities for important science operations and research that often require power drawn directly from the engine core. *Source: Back of card
