“Every star system has a plane in which its planets or other objects orbit. One side of that plane is labeled ‘up,’ and the other side ‘down.’ So up and down within the system doesn’t change regardless of how your ship is oriented. By the same token, the direction toward the star is ‘starboard’ while the direction away from the star is ‘port.’” Geary shrugged. “I’ve been told that early on they tried to use ‘starward’ instead of ‘starboard,’ but the older expression stuck.”
