On this edition of ST, we speak by phone with Ariel Waldman, a San Francisco-based writer and science advocate who is a fellow at the Institute for the Future, a National Academy of Sciences committee member, and the founder of Spacehack.org (which is a directory of ways to participate in space exploration). Waldman joins us to talk about her new book: "What's It Like in Space? Stories from Astronauts Who've Been There." It's a fun-to-read collection -- written for parents and kids alike -- that gathers eyewitness stories from dozens of international astronauts. These are, after all, men and women who've actually been there...and who have retured from space with accounts that are by turns weird, funny, interesting, insightful, and inspiring. Per Entertainment Weekly: "Charmingly illustrated.... These snippets are so clear, so beautifully curated, that they really do leave you with a sense of what it must be like to float miles above Earth."
