Two of the most remarkable spacecraft ever launched are the stars of this month’s episode: Voyager 1 and Voyager 2. Izzie and Dr Becky talk to Dr Jamie Rankin, the mission’s current Deputy project scientist, and editor Richard gets to chat to Ann Druyan, the original Creative Director of the Golden Record project, who worked alongside her husband Carl Sagan.
