Imagine that you are one of these pioneer astronauts. You will spend the rest of your life on your spaceship and will never again be part of a community on Earth. You will have to adapt to life in outer space, and you will experience the world in ways in which those left behind could only begin to imagine. Some aspects of your life will of course unfold along familiar lines – you will make friends, fall in love, and possibly have children and grandchildren. But overall, your new home, your new life, as well as that of any offspring you have, will be forged in a new environment and with a new community.
