Tiny Matters

When Artemis II lifted off this past April, marking humanity’s return to the Moon, people across the world were captivated. It was a triumph decades in the making, but also shaped by painful loss. In this episode of Tiny Matters, we trace the legacy of the Space Shuttle Challenger disaster on its 40th anniversary, unpacking what went wrong both scientifically and organizationally, and how the event necessarily helped reshape NASA’s safety culture. We hear firsthand from astronaut Terry Hart, who flew on Challenger less than two years before the accident, and from NASA’s acting Chief of Safety and Mission Assurance, Nathan Vassberg, about how Challenger — and later, Columbia — reshaped the way NASA thinks about risk, and how those lessons were applied to Artemis II. We also hear from Vanessa Bentley, professor of applied ethics who teaches a course dissecting the conflict between managers and engineers that led to the tragedy.

Did you know that over 75% of silent films have disappeared? The culprit: highly flammable film! We open this episode of Tiny Matters with a poker bet, a decades long grudge, and a garage full of film before we hop into the rise of nitrate (nitrocellulose) film and how it shaped film history. We chat with Robert Shanebrook, who literally wrote the book on Kodak film, and with collection manager Deborah Stoiber at the George Eastman Museum, the world’s oldest photography museum and one of the oldest film archives. We talk about the science of preserving and conserving the nitrate films that have survived, and why it’s so important for keeping cultural memories alive. Did you know that ‘George Eastman, Kodak, and the Birth of Consumer Photography’ is a National Historic Chemical Landmark? Read more about it here.
