Louis: If you were consigned spend the rest of your life in microgravity maybe you become some kind of uh shuttle pilots between earth and mars and back again. Louis: When we do have martians who are born on mars from parents who've gone there as astronauts they won't so much of a have evolved but their bodies will have permanently adapted this new environment. louis: They're likely to be quite torn and spindly because their entire skeleton body has developed and grown in one third earth gravity.
