I thought it was pretty funny how some of the characters seem to be almost plucked out of real life:

Doc Dubois = Neil DeGrasse Tyson
Sean Probst = Elon Musk
Camila = Malala Yousafai

Those are the only ones I could confidently identify, but it seems like some of the other characters could also have real life counterparts.

I want to say JBF = Hillary, but that may just be my own political bias speaking. Still I can't shake the thought that a President Hillary would figure out a way to survive against all odds regardless of laws or people in her way.

Another weaker association would be Marcus who seemed to personify Chris Hadfield in my mind as the "Mr Competent" character.

Any others? (even if just a loose association)
