Book Description
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.

Book Description
Remnants of the curious and peculiar ways humankind has marked the archaeological landscape are abundant but often ignored: wrecked aircraft, abandoned airfields, old highway billboards, derelict boats, movie props, and deserted mining operations. In this book, archaeologist P.J. Capelotti explores places and things that people do not typically think of as archaeological sites and artifacts, introducing readers to the most extreme fieldwork taking place today. Capelotti shows that even seemingly ordinary objects from the recent past hold secrets about the cultural history of humans. He investigates the site where a stunt copy of the Orca, the fishing boat used in the movie Jaws, was stripped to pieces by fans—a revelation of the ways humans relate to popular culture. He takes readers to abandoned base camps near the North Pole that are now used as destinations for Arctic tourism. Retelling the story of Thor Heyerdahl’s research expedition across the Pacific Ocean on a balsa log raft, Capelotti shows how experimental archaeology attempts to reveal cultural connections between continents. And he doesn’t stop at the limits of the planet. He discusses debris floating through outer space and equipment left behind on the surface of the moon, highlighting current efforts to preserve artifacts that exist beyond the Earth’s atmosphere. These discarded materials, says Capelotti, help archaeologists piece together the sweeping story of human cultural expansion and exploitation. He explains how the unusual sites of shorelines, sea, air, and space represent the farthest reaches of human civilization. His enthusiasm will inspire readers to set out on their own to investigate the secret meanings of treasures hiding in plain sight.
