These days science is viewed as a means to various ends. These ends are all wonderful...eliminate poverty, curtail climate change, cheaper energy, etc. But what's missing is the idea of doing something for the sake of doing it. It's not totally clear what landing on the moon or maintaining a space station really accomplished in terms of material goals. They're glorious accomplishments because of their difficulty.
I think that attitude is what's missing. Listening to JFK's "we will go to the moon" speech is almost unbelievable today. Politicians of either party absolutely cannot talk like that today.
