Dr Karen Olsson-Francis is the Director of AstrobiologyOU at the Open University, UK. Her team investigates the scientific, governance and ethical implications of space exploration. Her background is in microbiology of extreme environments, she is particularly interested in unique biosignatures that can be used as evidence of life. She has been involved in a number of astrobiology experiments onboard the International Space Station, which involved studying the effect of simulated Mars, icy moon and low Earth conditions on microbial and biosignature survival. She is also the UK representative on the COSPAR Planetary Protection Panel and was involved in writing a white paper on planetary protection of the outer Solar System.
Frank Postberg is a planetary scientist leading a research group at the Institute of Geological Sciences at Freie Universität Berlin.
