In July the world will be celebrating 50 years since Apollo 11, when Neil Armstrong took those historic first steps on the Moon. In this episode of the Physics World Stories podcast, Andrew Glester looks back at some of the lesser known stories from the Apollo era.

Glester catches up with Kevin Fong, presenter of 13 Minutes to the Moon, the BBC podcast exploring the final dramatic 13-minute descent of the Apollo 11 mission, when everything came close to going badly wrong. Fong explains why the Apollo rockets’ guidance systems were so ground-breaking at the time. He also describes the extraordinary psychology of the Apollo astronauts who risked their lives in the pursuit of progress.

Next up, Alan Andres speaks about Chasing the Moon, the book he co-authored with Robert Stone that has been turned into a PBS documentary. He discusses the complex dual life lived by Wernher von Braun, Nazi scientist-turned NASA rocket pioneer. Andres also explains why James Webb, the American government official who oversaw NASA from 1961 to 1968, left such a lasting legacy on the US education system.

Glester also visits the Cheltenham Science Festival in the UK where he catches up with a trio of Apollo aficionados. Science presenter Dallas Campbell shares some of his favourite stories including the surprising modest origins of the US flag that was planted into the lunar surface. Astronomer Nick Howes speaks about the social value of the Apollo programme and why we need to recapture the era’s spirit of adventure. While geoscientist Louise Alexander explains why it is still worth analysing samples of lunar rock returned during the Apollo missions.

Finally, you can hear an archive interview with Apollo astronaut Alan Bean, who went to the Moon on Apollo 12. Since retiring, Bean developed a passion for painting and creates works inspired by his adventures in space. This pursuit brought Bean the freedom of expression he never had as an astronaut where speed of thought and precision were among the required skills.

In the July episode of Physics World Stories, Glester will look forward to some of the missions that will see humans (and machines) return to our nearest celestial neighbour. Also look out for the July issue of Physics World magazine, a special issue devoted to the 50th anniversary of Apollo 11.
