Its central goal is to bring together those young people who are motivated and able to lead humanity into a peaceful and abundant future both on and off our planet. With personal relationships forged during an intense period of study and work as students, ISU alumni are expected to go out and create a worldwide network of friendship and achievement as they rise in the space professions. With grounding in the whole wide variety of space-related disciplines, they then can call on each other for help and counsel as they build the international space programs of the future. More than 2000 ISU graduates in more than 60 countries are already realizing this objective. ISU has two main programs: a peripatetic summer session and a Master of Space Studies curriculum at its permanent headquarters in Strasbourg. In each program students, in addition to their multidisciplinary core courses and individual assignments, carry out design projects intended to give experience in teamwork under stress and to generate influential results. The topics of these projects are deliberately selected to be difficult and important. In the 2002 summer session one project focused on space in the service of human health and the other focused on the new interdisciplinary realm of astrobiology - the study of possible universal life. This report deals with that project. Astrobiology has emerged from the world of speculation into the world of investigation because of suggestive new findings in several scientific fields: increased understanding of the fundamental processes of life on Earth, observation of life’s main elements and molecules throughout space, discovery of living microbes in extreme terrestrial environments, detection of the signatures of planets orbiting many stars, and above all the realization that life may be a common, perhaps even inevitable, result of cosmic evolution. With these tantalizing hints before us, it is time for a broad attack on the question - especially one that engages talent in each of the many relevant fields and in each of the many places where skills and resources exist. The students of the ISU 2002 astrobiology team devoted their energy to defining this attack. Here is their report. James Burke v FACULTY PREFACE Faculty Preface At every Summer Session Program of the International Space University, students carry out two design projects intended to give teamwork experience under stress and to generate analyses and recommendations on topics of current interest in the world’s space programs. In 2002, the two projects were about astrobiology and the use of space systems in improving human health. This document presents the results of the astrobiology project. Astrobiology is emerging as a new, interdisciplinary scientific field with information sources both on and off Earth. The ancient concept of a plurality of inhabited worlds has received new stimuli from recent discoveries – planets around other stars, microbes in extreme terrestrial environments, interstellar and stellar evolution involving the elemental building blocks of life. Given the rich diversity of the subject, the first task of the student team was to narrow the scope of their in- quiry. They decided to focus on likely progress over the next twenty years, concentrating on both ground-based and space-based activities that may realistically advance human understanding of the origins and distribution of Earth-like life in the solar system and around nearby stars. In choosing this focus, they deliberately excluded entities that may possibly live somewhere in the cosmos, not violating any currently known law of nature, yet being so different from our water and carbon based life that we might not even recognize them as alive. Within this scope, the team examined ways to investigate and possibly discover other life, from bacteria to galactic civilizations, and they also considered the likely social effects of a confirmed discovery. The focus of the report, along with the format, style, and management behind it, is the product of the participating students. The document you are reading is unique – its breadth and perspective could not be matched by a consultant, company, or national space agency. More than the results of an academic exercise,
