BSV Podcast 0099: W. David Woods

Balerion Advisor Doug McAdams sits down with W. David Woods, Apollo historian, author, and researcher, to discuss how Apollo flew to the Moon. Woods explains the orbital mechanics, spacecraft architecture, navigation systems, landing procedures, and mission constraints that made Apollo possible. He also discusses how Apollo’s technical achievements shaped computing, communications, and planetary science.Timestamped Overview00:00 – Introduction to W. David Woods and his work on Apollo history, the Apollo Flight Journal, and How Apollo Flew to the Moon 02:56 – Bird’s-eye view of Apollo mission design and the basic logic of traveling to the Moon and back 07:48 – Saturn V staging and the final spacecraft stack: command module, service module, and lunar module 11:08 – Entering lunar orbit, matching the Moon’s motion, and why burns are needed to stay at the Moon rather than free-return to Earth 13:04 – How the lunar module separates, descends from lunar orbit, and performs the landing burn 16:27 – Lunar module ascent from the Moon and rendezvous with the command-service module in lunar orbit 22:25 – Transferring crew and samples, shedding mass, and using the service module to begin the return to Earth 26:05 – Service module separation, atmospheric reentry, heat shield performance, and parachute recovery in the ocean 29:07 – Human factors, test pilot skill sets, crew roles, and how much of Apollo was automated versus crew-controlled 36:07 – Precursor lunar probes, communications systems, and what NASA knew about the Moon before landing humans there 40:38 – Redundancy versus low mass, Apollo’s tight engineering margins, and examples of elegant lightweight design choices 43:34 – Apollo as a Cold War national effort, the scale of NASA’s budget, onboard life support realities, and the practical problem of waste management in space 48:05 – Lunar terrain, navigation on the surface, Apollo 15’s anorthosite discovery, and Apollo’s lasting contribution to planetary science This is a public episode.
