Mae Jemison recently shared some illuminating recollections of her experiences as an astronaut, but they were neither the starting point nor the ending point of our conversation. This extraordinary woman's career is too packed with present and future endeavors to dwell very long on her stellar past. She currently leads 100 Year Starship, a nonprofit that aims to make interstellar travel a reality within the next hundred years. Jemison also leads Look Up, a movement that encourages people to connect with the sky above us on one day each year.
