Sharing Space with Astronaut Cady Coleman, Part 1

What is the overview effect? Why is slow fast when you’re spacewalking? And what would happen to Chuck and Allen’s hair in space?

To get the answers to these and other questions, Dr. Charles Liu and co-host Allen Liu welcome back astronaut, chemist, engineer, flautist, and most recently, the author of “Sharing Space: An Astronaut's Guide to Mission, Wonder, and Making Change,” Dr. Cady Coleman.

As always, though, we start off with the day’s joyfully cool cosmic thing, a micrometeorite pit 2 microns across found on a tiny volcanic glass beat that was part of the lunar regolith collected by China’s Chang'e 5 Lunar Sample-Return Mission. On the surface of the pit is a trace of Di-Titanium Oxide (TiO2) in mineral form that can’t exist on Earth.

Cady, who is a material scientist, talks about how this new discovery may not be as “new” as it seems, because we have much better detection technology for detecting it in lunar samples than we had during the Apollo lunar missions. She also explains how creating materials in space, unfettered by gravity, can be very different than here on Earth. She recounts the liquid physics experiments they did on her first Space Shuttle mission and how they could lead to innovations in the development of space toilets, among other things. (To find out more about space toilets and how to pee and poop in space, check out Appendix 1 of Cady’s new book!)

Our first student question today comes from Violetta, a student at “The School Without Walls” in Washington, D.C., who asks, “What is your outlook on the overview effect? Cady defines the effect, and how it changes people who go into space and see the planet below them. For her, she explains, “I knew I was going to go to space, and I just thought I’d be going to a different place. Then, when I got up there, I looked back at Earth, I still felt at home. It’s just that the whole place felt like home, and home was closer than I thought.”

Allen follows up Violetta’s question for Cady with one from Anne W., a fellow student, who asks, “How is Space?” Cady’s answer: “Space is Awesome!” She explains that here on Earth, we grow up with limits on what we can do, how far we can run, or how fast. But, in space, we’re constantly discovering more things that you can do: ”I love the flying.”

You’ll hear Cady share what it was like in space during her two Space Shuttle missions and 6 months on the International Space Station as a member of Expedition 26/27. She talks about her work schedules and experimentation and the self-induced tendency to work too much, to more personal activities like looking out the window, social media posting, and even shopping – or ordering a pizza from Domino’s like Ron Garan did, hoping to earn a free pizza since there was no way they could deliver it in 30 minutes or less! What would she do differently if she went back? Sleep more and take better care of herself, which she reminds us in equally important to all of us here on Earth.

Next, Chuck turns to some of the big ideas in Cady’s book, starting with “Slow is fast.” While holding up the very first copy of the book Cady ever got, she talks about spacewalking and how haste can be problematic. She takes issue with the phrase, “There’s no I in TEAM” and how in real life, it’s actually about what each individual member brings to the team.

Part One of our interview with Cady ends with a discussion of the t-shirt she’s wearing from “People Love Art” who she met through her work with AstroAccess, a project dedicated to promoting disability inclusion in human space exploration by paving the way for disabled astronauts.

There’s plenty more of our interview with Cady, so please tune in in two weeks for Part 2. But, until then, you can find out more about her new book and everything else she’s up to on her website: https://www.cadycoleman.com/.
