A short clip of Dr. Robert Zubrin, author of The Case for Mars, answering why humanity should go to Mars. He argues that societies grow by challenging themselves and that exploration inspires young people.

Liz Rice builds a container from scratch in about 100 lines of Go, showing that a container is not a lightweight VM but a set of Linux kernel features and flags.

Bruce Waggoner of the Voyager team describes how engineers diagnosed Voyager 1's 2023 loss of telemetry and patched its flight software from 15 billion miles away. The talk covers the spacecraft's architecture and the scarcity of old documentation.

Nickolas Means tells the story of Lockheed's Skunk Works and how its engineers built the U-2, SR-71 and F-117 under tight deadlines and budgets. He draws lessons for modern software teams.

JPL's David Cummings presents at the 2025 Flight Software Workshop how the team diagnosed and fixed the 2023 Voyager 1 anomaly from billions of miles away. It walks through the flight computer and the memory fix.

Brian Troutwine's Code Mesh 2015 talk on the Apollo Guidance Computer. It covers the AGC's design, core rope memory, its interrupt and software behavior, and the pioneering engineering effort behind it.

Stuart Armstrong of the Future of Humanity Institute gives an Oxford physics talk on what exploratory engineering suggests about the Fermi paradox. He argues that von Neumann probes and Dyson spheres are plausibly buildable and asks what traces advanced civilizations would leave.
