After listening to the first episode, which was well done, I can recommend the new “13 Minutes to the Moon” BBC World Service podcast, promoted as “The full story of the people who made Apollo 11 happen and prevented it from going badly wrong.”
It will run for twelve episodes – if they’re all 45 minutes like the first one, that will be nine hours total.
Background on the series: Apollo Moon landing: The 13 minutes that defined a century
