Dr. Kelly Weinersmith (@FuSchmu) is the co-author (with her husband Zach) of Soonish and A City on Mars. Kelly maintains that while having humans living off Earth would be awesome, we’re simply not ready for it yet. She answers many of my questions: Why can’t we go to Mars if we have the will? Why can’t we all just get along? Why should we expand? Why is building a habitable space station harder than settling on Mars or the moon? What laws would apply in any off-Earth settlement? Where should we focus our space research efforts?
Kelly also goes on a rant about Helium 3.
