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?

@ZachWeinersmith Antarctica is cool enough.

@dtl @ZachWeinersmith It’s the rarity value though: I’ve been to Antarctica four times, including spending the winter there. That makes me unusual, but not astronaut-level unusual. Go to the right university department and you’ll meet other people like me, but astronauts? Yeah, rarer than hen’s teeth.

(Unsurprisingly many Antarctic people, myself included, applied for the job Tim Peake eventually got. Some even got interviewed. But ultimately at the time they wanted a test pilot.)
