Space isn’t a dead-end, it’s just taking us longer to figure out than our earliest trajectory. The New Yorker has a great look at The Race to Develop the Moon for industrial purposes:
Lunar construction projects now look feasible. “Down the hall, we have a telerobotics lab,” Burns said. “You could print components of habitats, of telescopes. You use the lunar regolith”—the dust of the moon—“as your printing material. You could print the wrench you need to fix something.” Fifteen years ago, the moon was believed to be a dry rock; now we know that there’s water there. Both private industry and national agencies regard the mining of water and precious materials as something that’s not too far off.
Only twelve people have walked on the moon, all of them between the summer of 1969 and Christmas, 1972. All the moonwalkers were men, all were American, all but one were Boy Scouts, and almost all listened to country-and-Western music on their way to the moon; they earned eight dollars a day, minus a fee for a bed on the spacecraft.
Buzz Aldrin had hoped, and briefly expected, that it would be he, and not Neil Armstrong, who would take the first human step on the moon. The astronaut Michael Collins, who manned the control module that orbited the moon while Armstrong and Aldrin walked below, has said of Aldrin that he “resents not being first on the moon more than he appreciates being second.” On the moon, Armstrong took photos of Aldrin posing, but Aldrin took none of Armstrong doing the same. One of the few photos that shows Neil Armstrong on the moon was taken by Armstrong himself—of his reflection in Aldrin’s helmet, as Aldrin salutes the flag. We are petty and misbehave on Earth; we will be petty and misbehave in space.
Futurism isn’t dead, it’s just not all around us like Tomorrowland promised.
