I grew up with space travel, first in fiction, then in fact. I loved it, and the kids I taught loved it, too. How much of that rubbed off from me, I’ll never know.
By the time I started teaching, the big show was over. When Gene Cernan stepped back into his LEM in 1972, it was the high water mark of manned space exploration. It’s been downhill since.
In the classic science fiction novel I had planned to serialize, Rip Foster is heading out toward the asteroid belt on the nuclear powered spacecraft Scorpius. That’s how we all thought the future would look. That’s how the future should have looked. Chemically powered rockets are simply not sufficient for exploring the solar system.
We have have nuclear power plants for electricity, nuclear submarines, nuclear aircraft carriers, even a nuclear cargo ship. Why not nuclear spacecraft? Weight? Do you really think we couldn’t have overcome that problem? Maybe it was the danger, but . . .
Here is a quiz for you. How many nuclear submarines are lying on the bottom of the ocean, tombs for sailors and ecological time bombs for the rest of us? Two from America and six from Russia. An additional Russian nuclear sub sank twice, but was raised both times.
How many nuclear and thermonuclear bombs have gone missing? The U.S. admits to eight. How many more are hidden under the umbrella of security? Your guess is as good as mine. How many have the Soviet’s lost? You ask them, I’m keeping my head down.
Did I mention Chernobyl and Fukushima?
Let me put it another way. When the Soviets launched Sputnik and initiated the space race, then followed up with a man in orbit before we could even launch a sub-orbital flight, we did an end-around and went to the moon.
If the Soviets had launched a nuclear powered space craft, we would have launched a nuclear powered space craft. Technology would not have stopped us. Fear of radiation would not have stopped us.
That was then, this is now. The best thing for manned space exploration today – though not for American interests or world peace – would be for the Chinese to launch a nuclear powered space craft. It wouldn’t even have to be a good one. Just the threat would be enough, and in a few decades ships like the Scorpius would be filling the solar system.
