Eleanor S Armstrong (Ellie) is a social scientist of outer space. Her research investigates the disjoint between discourse and practices of space science, and socially just methods to address these disconnects. Her doctoral research at UCL (UK) analysed narratives constructed in London science museums. Ellie expanded her work on the colonial geographies of space science in her Postdoctoral Fellowship at the University of Delaware (USA) and as a visiting scholar at the University of Cambridge (UK). Ellie is interested in informal education and leads LGBTQ+ museum tours and runs zine workshops. She was previously co-chair of Science London, an organisation supporting equity, diversity and inclusion in science communication practice. Ellie is a member of the UCL IAS Center for Outer Space Studies and of Transformational HPS.
