It’s space book club time, featuring the latest book by author and photography expert Andy Saunders: Gemini and Mercury Remastered. Producer Richard enthuses about these mid-60s missions and we talk to the author. Meanwhile, Dr Becky, Izzie and Dr Robert also discuss Project Hail Mary by Andy Weir and A City on Mars by Kelly and Zach Weinersmith. With questions on the size of space and why the centres of galaxies are brighter, it really is quite the bonus episode.

You can hear a longer version of the interview with Andy Saunders in the latest Space Boffins Podcast.
