This episode, University of Edinburgh PhD candidate Mia Belle Frothingham chats with Dr Frances Westall, leader of the Exobiology Group of the CNRS in Orléans (France). We talk about Frances's diverse and inspiring path, the dramatic and divisive period after a Martian meteorite found (ALH84001) in Antarctica in 1984, and the politic motivations behind false pretences of the discovery of extraterrestrial life.
