Science Fiction is a continually compelling genre. For me, anyway. Judging from the number of space and clone and and and things coming out, it is for a lot of people.
So, what's my first mental impression when I think "Oh, SciFi"?
Space. Really and primarily, space. Space travel, space ships, worlds that are not Earth. Worlds that may once have been Earth. I sometimes think about things like my brain in a robot body (or a cloned body! Thanks Richard K. Morgan, for Altered Carbon and the subsequent two books. I'd love for there to be more).
If there's a science for it, there's a fiction for it, so Science Fiction possibilities, in my mind, are fairly infinite. But when it comes down to it, when I write (or make gestures at writing) what I think of as "Science Fiction", I'm reaching back to that Golden Age of Space Travel and Possibilities, where Man willingly travels at the behest of his (or her; I'm using "Man" as the gender neutral noun here) government to Explore and Discover and what have you. I want that mood of the indomitable spirit, the inquisitive attitude, the endless question of "What will we find and how will we survive it?"
I've already got an idea somewhat laid out for a near-future Moon novel. I now, I think, have the most nascent dream of a novel somewhere along that timeline, after the events of Untitled Moon Novel are said and done, and we (meaning Earth People) have moved even further.
What do you think of when you think of SciFi, be it books or movies?
