In this episode we speak with David Baker, who wrote a fascinating book about spy satellites. We cover the political and military context that drove their development, their (known and suspected) capabilities, methods of recovering the images, as well as typical orbits and the sartellites’ ability to change that orbit for quick repositioning.

Dr. Douglas Hofmann works as a scientist in the Metallurgy Lab at NASA’s Jet Propulsion Laboratory. I visited Doug during my US trip earlier this year, and we chatted about metallic glass. In particular, we discussed its properties, how to create it in bulk, how to test its properties, as well as how and why it is interesting for use in space.

David Woods has a new book out, so of course he has to talk about it on omega tau :-) His recent book is about the Saturn V launch vehicle, i.e., this time it is about the rocket, not about the spaceship. In this episode we dive into lots of details that we did not cover in the two Apollo episodes (episodes 83 and 97) — make sure you have listened to those before you listen to this one.
