Something I have trouble explaining about space travel. Like, if you've read my book, you know I think human space faring is probably not economically valuable. It's not a good use of science dollars compared to other areas. I'm even skeptical of the case for inspiration (it doesn't seem to causally related to more aerospace degrees).

But it's also just really cool. Why don't I feel this way about Antarctica or Seabed exploration?

I suspect they’re closely related. The simple fact that sending someone into space and bringing them back alive (let alone keeping them alive and healthy for more than a short period) is so monumentally difficult is the root cause of both the coolness and the lack of viable economics.
