Who from my generation could forget the original "Star Trek" series on TV? Fan or not, who now is not aware of "Trekkies" going from convention to convention, dressed in full-blown costumes as Starfleet officers, Vulcans, Klingons, Romulans and others?
The original series ran for only three seasons, but endures and continues to make an impact. The ideas and shows were very creative, and touched on many themes that are still relevant today, including provocative ones such as issues with race and discrimination.
Several follow-on series resulted over the decades — including the new "Star Trek: Discovery" debuting Sunday (Sept. 24) — and "Star Trek" movies are still being made. But I still like the original best, and I never really kept up with the more contemporary ones. [The Best "Star Trek" Episodes Ever]
"Star Trek" was inspiring to me. I admired Captain Kirk (William Shatner) but saw myself more as Mr. Spock (Leonard Nimoy), the science officer. The show reinforced my fascination with space and our universe, and my desire to become an astronaut myself. Decades later, I was thrilled to meet Leonard Nimoy when he moderated a space exploration panel discussion, of which I was a part. (Editor's note: Chiao served as the science officer on the International Space Station.)
The original "Star Trek" series predicted several technologies that have already come and gone — for example, storage devices about the size and shape of the 3-1/2-inch floppy disc and, of course, the flip phone. (I loved my old Motorola.)
While we don't yet have the medical tricorder, some technologies are getting closer. And I'm still waiting for someone to develop warp engines, transporter and tractor beams, and phasers.
During the time of the VHS recorder, I was able to record most of the episodes on late-night TV reruns. They are still around somewhere, and I actually still have a functional player. Back then, I used to watch my favorite episodes over and over. My wife recently signed the family up for Netflix, which is much easier, and I have begun to watch the original series again.
Maybe it's simple nostalgia, but to me, they seem even better now.
