Bennu, named for the ancient Egyptian phoenix, was the chosen destination of OSIRIS-REx, NASA’s premier mission of asteroid exploration, launched in 2016. Study of the asteroid is important in safeguarding the future of planet Earth, but Bennu is also a time capsule from the dawn of our Solar System, holding secrets over four-and-a-half billion years old about the origin of life and Earth as a habitable planet. In 2020 the OSIRIS-REx spacecraft successfully landed on the surface of Bennu and collected pristine asteroid material for delivery to Earth in September 2023. Scientific studies of the samples, along with data collected during the rendezvous, promise to help find answers to some of humanity’s deepest questions : Where did we come from ? What is our destiny in space ? This book, the world’s first complete (and stereoscopic) atlas of an asteroid, is the result of a unique collaboration between OSIRIS-REx mission leader Dante Lauretta and Brian May’s London Stereoscopic Company. Lauretta’s colleagues include Carina Bennett, Kenneth Coles, and Cat Wolner, as well as Brian May and Claudia Manzoni, who became part of the ultimately successful effort to find a safe landing site for sampling. The text details the data collected by the mission so far, and the stereo images have been meticulously created by Manzoni and May from original images collected by the OSIRIS-REx cameras.

What is life? How, where, and when did life arise? These questions have remained most fascinating over the last hundred years. Systems chemistry is the way to go to better understand this problem and to try and answer the unsolved question regarding the origin of Life. Self-organization, thanks to the role of lipid boundaries, made possible the rise of protocells. The role of these boundaries is to separate and co-locate micro-environments, and make them spatially distinct; to protect and keep them at defined concentrations; and to enable a multitude of often competing and interfering biochemical reactions to occur simultaneously. The aim of this Special Issue is to summarize the latest discoveries in the field of the prebiotic chemistry of biomolecules, self-organization, protocells and the origin of life. In recent years, thousands of excellent reviews and articles have appeared in the literature and some breakthroughs have already been achieved. However, a great deal of work remains to be carried out. Beyond the borders of the traditional domains of scientific activity, the multidisciplinary character of the present Special Issue leaves space for anyone to creatively contribute to any aspect of these and related relevant topics. We hope that the presented works will be stimulating for a new generation of scientists that are taking their first steps in this fascinating field.
