As an adult, my favorite style of science fiction is that set in worlds entirely possible in our future. As much as I love Star Trek (TNG all the way!) it’s much more science fiction fantasy than a glimmer of hope for a real future, as I had always imagined as a kid.
The fact is that we won’t be traveling at warp speed anytime in our conceivable future. More realistically, humans will be traveling much more slowly amongst the stars. Even if we could travel at the speed of light, it would take one full year to go the distance of one light year, and then another year back. When you start plugging in the distances of any of the nearest stars that we’ve discovered having exoplanets, whole generations will have waxed and waned before those who left on the journey could even get home, and that’s only if the travelers were in suspended animation and didn’t experience the true passage of all that time.
One thing that is becoming abundantly clear is that humans will need help while traveling to other planets; we’ll need robots to assist us along the way. We’re already seeing great advances in robotics, and it isn’t unreasonable to imagine a skeleton crew of robots scuttling around a space ship, maintaining its function and safety while the crew is tucked snugly in their cryo-stasis pods.
*FYI, to be Fireflied is when a sci-fi series (fantasy in some instances) with incredible potential is canceled unjustly, without even a chance to develop, such as it happened to Firefly, Earth 2, Legend of the Seeker, and Krod Mandoon and the Flaming Sword of Fire!
