Not so very long ago, this orbiting observatory was a twinkle in a science fiction writer’s eye. In the 1920s, German rocket scientist Hermann Oberth wrote a book called Die Rakete zu den Planetraümen, in which he described a telescope attached to a station in geosynchronous orbit. While the Hubble Space Telescope isn’t in geosynchronous orbit, it certainly fits Oberth’s dream of off-planet astronomy observing.

I first found out about this book when I was interviewing another scientist — the late Lyman Spitzer of Princeton University. Dr. Spitzer was also a science fiction fan, and in the course of several pleasant conversations with him, we both shared our favorite book titles. My love for science fiction (which, along with my dad’s habit of taking me out to the see the stars), kindled my interest in astronomy and space science. In high school I read things like Clarke’s Childhood’s End and many of Robert A. Heinlein’s juveniles as if they were treasures. Today I have hundreds of back issues of science fiction magazines in my library and a fair collection of SF books. Periodically I take some old favorite down from the shelf, cuddle up on the sofa, and lose myself in some distant planetary system, exploring with beings that only a writer could imagine.

Yet, there’s a reality that springs from science fiction that we cannot deny. Many of today’s missions — from orbiting shuttle and space station endeavors to flybys of distant planets — once existed as ideas in the realm of science fiction. It took humans a few decades to catch up to some of the SF dreams outlined in this body of literature, but there is much more to accomplish. I would love it if science fiction were a sort of self-fulfilling blueprint for the future of the human race, although I realize that many SF dreams will never come true. But, that body of literature sits there — beckoning us to our future. If we’re on our toes, it’ll keep us moving ever onward and outward.
