Michelle Dougherty reveals how a strange magnetic signal led to finding a water plume on Saturn's moon Enceladus.
Lauren Laverne opens by placing Professor Michelle Doherty in a line that runs from Charles II's interest in navigation to Charles III appointing the first woman Astronomer Royal. The episode does not stay grand for long, which is a relief. It goes back to Durban, to a civil engineer father who made science feel possible, and then out toward planets, extraterrestrial life, and Doherty's current leadership role on a mission to Jupiter. The best moments come when Doherty admits what she did not know. She arrived at Imperial College after applied maths and work on the solar wind, then found herself looking at data for the first time. Laverne catches the surprise without overplaying it. Doherty laughs and describes getting on with the work instead of acting as if she already understood it. Risk, in her telling, is not swagger. It is saying yes before you are fully ready, then finding out whether you can grow into the job. The second half moves closer to home. South Africa was still loved, still present, but the work took her to Germany and then the United Kingdom. Before cell phones, closeness meant weekly letters, saved coins for Sunday calls, and money set aside for Christmas visits. Doherty says that was when she grew up. What sounded like travel became a different life, because the spacecraft missions arrived and she could not quite walk away. Her fourth music choice, We Three Kings, brings Christmas into the room without forcing the feeling. The episode lets ambition and homesickness share the space.
