@ZachWeinersmith Strongly considering picking this up (I enjoyed the previous books I've gotten from you), though, weirdly, almost to the exclusion of the 'on mars' bit.

But it looks like that's more of a title than a 'limiting to this specific thing', which, good! I want to read some in depth analysis of space-based manufacturing (among other things, and possible gravity as it relates to reproductive health, etc).
