The book will provide a historical perspective about the lives – not just the science – of the scientists who worked in the fields of study that formed the foundation of our current work to understand the conditions for life in the universe. Astrobiology became a mainstream topic with the announcement in 1996 that fossilized life had been found in martian meteorite ALH84001; that claim has since been discredited. Nonetheless, it followed the 1992 announcement of the discovery of planets orbiting around a pulsar and reinvigorated investigations and debate about conditions required for the origin(s) of life on Earth (partly based on Stanley Miller’s work in 1952) and the possibility of life beyond Earth. The book will also include memoirs of current scientists at all career stages who are actively investigating conditions and requirements for the origin, sustainability, and habitability of life on Earth, and the possibility of life on Mars and exoplanets. The diversity of topics, perspectives, career stages, and career paths and placements provided by the authors themselves will be an appealing read for people who are interested in learning more about the multifaceted field of astrobiology.
