Exploring Space, Exploring Earth (Hardcover)

This book describes the impact of space flight on geology and geophysics, beginning with a foreword by Neil Armstrong, which illustrates how the exploration of space has lead us to a far deeper understanding of our own planet. Direct results from Earth-orbital missions include studies of Earth's gravity and magnetic fields. In contrast, the recognition of the economic and biological significance of impact craters on Earth is an indirect consequence of the study of the geology of other planets. The final chapter presents a new theory for the tectonic evolution of the Earth based on comparative planetology and the Gaia concept.

Paul Lowman has been involved in a wide range of space research programs at the Goddard Space Flight Center. In 1963–4 he took part in planning for the Apollo missions. He was Principal Investigator for Synoptic Terrain Photography on the Mercury, Gemini, and Apollo earth orbital missions, an experiment that laid the foundation for Landsat. Between 1965 and 1970 he taught lunar geology at the University of California, Catholic University of America, Washington DC, and the Air Force Institute of Technology. Dr Lowman was also involved with the Mariner 9 Mars mission, the Apollo X-ray fluorescence experiment and Apollo 11 and 12 sample analysis among others. His main research interest was and still is the origin of continental crust, as approached through comparative planetology. In 1974, Dr Lowman received the Lindsay Award from the Goddard Space Flight Center. He was elected a Fellow of the Geological Society of America in 1975, and of the Geological Society of Canada in 1988. Drawing on his dual career in terrestrial and lunar geology, he authored Space Panorama (1968), Lunar Panorama (1970), and The Third Planet (1972). He also contributed to Mission to Earth (1976), the first NASA compilation of Landsat pictures edited by N. M. Short.
