In this episode, Rose Doyle (@RoseDoyle_) talks to Dr Rosa Santomartino (@RosaBiorosa) of the UK Centre for Astrobiology (@UKAstrobiology) about her research that’s “out of this world”. Rosa talks about her journey to become an astrobiologist, specifically Astromicrobiology: the study of microorganisms and their behaviour in an extra-terrestrial environment. We hear about her work on sending microbes to space to mine precious metals from asteroids. She then discusses the potential—and current limitations—of sending microbes to space.
