We jump right back in where we left off in Part 1 of our interview with Dr. Cady Coleman, astronaut, chemist, engineer, flautist, and most recently, the author of “Sharing Space: An Astronaut's Guide to Mission, Wonder, and Making Change.” (If you missed it, listen to Part 1 here.) 

Chuck asks Cady to tell us more about NASA’s decision to not include small and extra-large spacesuits to “save space.” She explains how, a few months later, they reinstated the extra-large suits, but not the small suits that affected about a third of the women, and the serious impact that decision had.

Chuck and Cady discuss the importance of diverse perspectives in the exploration of space. And then Cady offers her ideas about how to change the world for the better and the importance of doing what you can to help the people who come next. You’ll hear about astronaut Ron Garan and his nonprofit’s efforts to provide millions of filter straws to allow people in Africa to have access to safe, clean water. And you’ll hear about how you can purposefully shift your own perspectives.

For Part 2’s first question, Anne W. a student at “The School Without Walls” in Washington, D.C., asks, “What are some common reasons as to why people don’t become astronauts after starting training?” Cady explains why that rarely happens, mostly due the quality of the candidates who make it that far. But Cady then talks about why some people who should get selected to become astronauts don’t, and she shares some of her reasoning for the applicants she’s selected. The reason Cady stresses most is that if you don’t show them who you really are on the application, they cannot pick you. And she also explains the surprising reason why some astronauts who have flown already don’t get selected to go again.

The conversation circles back to diversity and bias in NASA. Allen shares the story of test pilot Ed Dwight, which he believes reflects some racial bias. Cady, who knew Ed, talks about some of the political factors in the choice, but also what an amazing artist he became. She reflects on the importance of Sally Ride in her life, and wonders what would have happened if the original Mercury 13 had been allowed to become astronauts back in the 60s.

Charles and Allen bring up Valentina Tereshkova, the cosmonaut who became the first woman in space in 1963, and how it took until 1983 for Sally Ride to take her famous flight as the first American woman. And yes, Cady does bring up “For All Mankind!” and “the role that art and storytelling can play to move the needle a little faster.”

For our final question, Allen shares a question from our podcast producer Leslie M., who asks, “Would materials behave differently in a different universe?” Cady, a chemical engineer who studied chemistry at M.I.T. and then got her Ph.D. degree in polymer science and engineering from the University of Massachusetts Amherst, says yes. And that kicks off a discussion of the impact of different physics on different materials. But Cady also talks about the importance of using the compelling nature of space to drive kids to want to become more educated and to improve life here on Earth.

In addition to Cady’s new book, Cady was recently in a documentary on PBS, Amazon Prime, and Apple TV, along with her family, NASA personnel and other astronauts. It’s called “Space: The Longest Goodbye” and it’s about how we are going to send people to Mars and put the human into human spaceflight.
