Tranquility is the art of being free of stress or disturbances.  We named the first place we set foot on Luna the Sea of Tranquility.  And it was a top candidate name for the first six Alliance colony worlds.  It finally won a majority vote for the seventh colony, and the first landing spot for the first colony ship is named Tranquility Base in honor of the Lunar Landing.  I show visitors the replicas of Apollo Eleven and Tranquilitas One we maintain there.
