Space Commerce relates the story of private enterprise's unsteady rise to prominence as a major influence on world space policy and research. The first space race proved the technological and military prowess of the two superpowers; but since the 1970s that contest has been supplanted by a multinational struggle to command the commercial opportunities of space.

The commercial space age was born in 1965 when Early Bird, the first commercial communications satellite, went into orbit. With characteristic ingenuity, American industrialists began to dream of garnering billions of dollars per year from space-based products and services. In the microgravity of space, they hoped, hitherto unavailable drugs could be produced that would revolutionize medicine; in the high vacuum of space, crystals of extreme purity could be grown in orbital laboratories, both for biological research and for application in the manufacture of advanced microcircuits.

In this book John McLucas covers the broad sweep of space commerce, both the vision and the reality: the construction of communications satellites and their ground control stations; the sale and leasing of communications services; remote sensing and measurement of earth's processes; navigation by satellites, serving ships, airplanes, and automobiles; the design and deployment of space laboratories for scientific research and product development; and life science experiments to determine the effects of space habitation on humans.

Drawing on his considerable expertise, McLucas brings a sober perspective to his assessment of the technological accomplishments as well as the challenges still faced by industry in space. He incorporates into his discussion an illuminating analysis of the economic and political impact of space commerce and its rapidly changing international character.

Intense heat and drought in the summer of 1988...greenhouse warming...acid rain...the ozone hole...rain forest destruction...Hurricane Hugo: "The Endangered Earth" is making headlines around the world, and we are aware as never before of the fragility of the global environment and our own vulnerability to climate change. Yet, despite the technological advances of the last three decades, our knowledge of how the Earth's systems work and interact remains incomplete at best. To determine environmental policies for the future, we need more information and better global climate models.

In Planet Earth D. James Baker provides a concise, up-to-date overview of the ongoing international research efforts that will improve our ability to predict global climate change. In straightforward terms, Baker describes remote sensing from space. He reviews extant spacebased satellites and their instruments and describes the areas in which operational and research missions are gathering ever-increasing data--on Earth-sun interaction, land vegetation patterns, ocean color, temperature, the atmosphere, the ice sheets of the polar regions, the shape and motion of the Earth's crust, the Earth's gravity field--which fill in gaps in our knowledge even as they raise new questions about critical global processes. In view of these questions and the subsequent need for more accurate global models, the satellite networks being planned for the 1990s will require state-of-the-art instrumentation, a new generation of supercomputers, and a high level of international cooperation if they are to succeed. Baker focuses on the United States initiative, Mission to Planet Earth, a long range attempt to study the planet as a whole using polar-orbiting, geostationary, and special orbit satellites coupled with a network of ground stations. In the concluding chapter, the author looks to the next century and examines the difficult long-term problems-of national security, technology transfer, data dissemination, cost, international coordination--that could undermine the achievement of the global operational system he proposes.

Planet Earth is a timely, well-illustrated introduction to Earth-observing satellite technology for the nonspecialist and specialist alike. It distills complex information that is otherwise available only in the technical literature. For those who follow space research, it will prove an indispensable guide.
