Dr. Christopher Mason was a leader on the pioneering NASA Twin Study. He wears many hats as he works as a professor and researcher at Weill Cornell Medical School. Just after the Inspiration4 Launch in September 2021, he sat down with us to talk about his work mapping human genomes and how space changes us. Much of our conversation is framed around his book The Next 500 Years Where he maps the scientific breakthroughs needed and ethical questions posed to allow life to exist on many planets.
