Since humans have been a species, there has always been a frontier. Whether it be Alaska for the first settlers of the Americas, or the New World (for Europeans), or the Wild West (for White Americans), there has always been an "over there" to explore. Today, our frontiers are the frozen Arctics, the deep seas, and the vastness of orbital space.
Science fiction has always stayed one step ahead. A hundred years ago, Jules Verne took us 20,000 leagues under the sea. A generation later, Edgar Rice Burroughs took us to Darkest Africa, lost continents, and fancifully rendered nearby planets,. Astounding and its ilk of the 30s and 40s gave us scientific jaunts through the solar system.
These days, one is hard-pressed to find stories that take place on Mars or Venus. Now that four men have circled the Earth and probes have flown millions of miles from our planet, tomorrow's frontier lies among the stars. Thus, science fiction has taken up residence in the spacious quarters of the Milky Way, light years away from home.
