Ross Douthat wonders what happened to it:
Go back and read the science fiction of the 1940s and ’50s, and you’ll be struck by the vaulting confidence that this expansion would continue upward and outward, and that a new age of exploration was just waiting to be born.
Today that confidence has vanished. Our Mars rovers are impressive and our billionaires keep pouring money into private spaceflight, but neither project captures the public’s imagination, and the very term “Space Age” seems antique. The Kepler 62 discovery might have earned more headlines at a less horrific moment, but it would have fallen out of the news soon enough.
It’s possible that we’re less interested in space travel because we feel that it’s a luxury good at a time when we have bigger problems here on Earth. But it’s also possible that we’ve gradually turned inward, to our smartphone screens and Facebook profiles, because we know that spaceflight isn’t going to get us to another world anytime soon.
Actually, if the latter is the case, “we” are too pessimistic, because we’re paying too much attention to NASA’s dysfunction, and not enough to what’s happening in the real world of spaceflight. I do think that the billionaires are capturing peoples’ attention, and as real things start to happen, they’ll do so much more.
