Independence is the heart of the Tau Aurigae system.  It’s also the name most people call the entire system, even the locals.  The world was discovered by one of the last NASA missions, the Independence Seven genuine rocket ship.  No gravtech back then.  She was the first ship to penetrate The Wall of debris that surrounds local space.  The Terran Bubble we call it now.  It was the only space we knew then, and breaking through The Wall was our greatest achievement.
