Welcome back, Christina Koch

Someday an inspirational children's book may be written about Christina Koch, an astronaut who just returned to Earth after traveling 139 million miles on the International Space Station. Her advice to others sounds like something Audrey Evans and other early women in medicine would say: "My main message to anyone who has a dream is to follow your passions. Be true to yourself, do what you love and live the life that you've imagined for yourself."

Brava, Christina! Brava! Photo by NASA shared on Wikimedia Commons.
