Current Aspects of Exobiology covers the philosophical aspects, scientific approach, and related research problems in exobiology. Most of the chapters are presented at the Current Research in Exobiology Symposium, held at the Jet Propulsion Laboratory on February 26-28, 1963. This book is composed of 10 chapters and begins with an overview of the nature and occurrence of extraterrestrial living matter. The next chapters survey certain line of evidence concerning extraterrestrial life, including investigation of organo-chemical evolution, organic remains in meteorites, microorganisms of Middle Precambrian Age, and the survival capabilities and the performance of earth organisms in simulated extraterrestrial environments. These topics are followed by discussions on the interesting issues on the possibility of a primordial lunar life and the possibilities of life on mars. A chapter considers the various scientific efforts to detect life outside earth, including experiments on small, unmanned biological laboratories to the surfaces of the planets. Another chapter looks into the possibility of the accidental introduction of terrestrial microorganisms to other planets during the course of space exploration by unmanned spacecraft. The concluding chapters explore the potential of radio search for other intelligent species in space. Exobiologists and researchers in the related fields of exobiology who are interested in extraterrestrial life will find this book invaluable.

The Origin of Life on the Earth covers the proceedings of the First International Symposium of The Origin of Life on the Earth, held at Moscow on August 19-24, 1957. This symposium brings together numerous scientific studies on the evolutionary principles and the different stages in the evolutionary development of matter. This book is organized into seven parts encompassing 60 chapters. The first parts discuss evidence that on the formation of hydrocarbons and their derivatives on the surface of the Earth even before the emergence of life. The subsequent parts are devoted to the many asymmetrical syntheses under the influence of circularly-polarized ultraviolet light, by catalytic reactions occurring on the surface of quartz crystals, and spontaneously by slow crystallization from solutions. These topics are followed by reviews on the possible means of abiogenic formation of amino acids, porphyrins, protein-like polymers, polynucleotides and other high-molecular organic compounds. Considerable chapters explore the complete possibility of the primary formation of these compounds on the surface of the Earth even before life was present on it. Other general topics covered include nucleic acids, nucleoproteins and viruses. The last part considers general biochemical problems connected with the further development of metabolism. This book will be of value to astronomers, physicists, geologists, chemists, and biologists.
