At the dawn of the twenty second century, we had a bustling interplanetary economy.  Colonies on Luna, Mars, Venus, the Asteroid Belt, and the moons of Jupiter and Saturn had spread our race throughout the Terran System.  We planted colonies and factories and mines everywhere we could land.  Hundreds of thousands of us lived away from Earth.  We were a true interplanetary civilization.  And then we found hyperspace and the stars opened to us.
