To a Rocky Moon
When human exploration of the lunar surface began in 1969, it marked not only an unprecedented technological achievement but also the culmination of scientific efforts to understand lunar geology. Memoirs of the Apollo astronauts have preserved the exploratory aspects of these missions; now a geologist who was an active participant in the lunar program offers a detailed historical view of those events--including the pre-Apollo era--from a heretofore untold scientific perspective. It was the responsibility of the scientific team of which Don Wilhelms was a member to assemble an overall picture of the Moon's structure and history in order to recommend where on the lunar surface fieldwork shoul...

To See the Unseen
A comprehensive & illuminating history of this little-understood, but surprisingly significant scientific activity. Quite rigorous & systematic in its methodology, the book explores the development of the radar astronomy specialty in the larger community of scientists. More than just discussing the development of this field, however, the author uses planetary radar astronomy as a vehicle for understanding larger issues relative to the planning & execution of "big science" by the Fed. government. Sources, interviews, technical essay, abbreviations, & index.
The Last of NASA's Original Pilot Astronauts
Resulting from the authors’ deep research into these two pre-Shuttle astronaut groups, many intriguing and untold stories behind the selection process are revealed in the book. The often extraordinary backgrounds and personal ambitions of these skilled pilots, chosen to continue NASA’s exploration and knowledge of the space frontier, are also examined. In April 1966 NASA selected 19 pilot astronauts whose training was specifically targeted to the Apollo lunar landing missions and the Earth-orbiting Skylab space station. Three years later, following the sudden cancellation of the USAF’s highly classified Manned Orbiting Laboratory (MOL) project, seven military astronauts were also co-opted into NASA’s space program. This book represents the final chapter by the authors in the story of American astronaut selections prior to the era of the Space Shuttle. Through personal interviews and original NASA documentation, readers will also gain a true insight into a remarkable age of space travel as it unfolded in the late 1960s, and the men who flew those historic missions.
Lakes on Mars
On Earth, lakes provide favorable environments for the development of life and its preservation as fossils. They are extremely sensitive to climate fluctuations and to conditions within their watersheds. As such, lakes are unique markers of the impact of environmental changes. Past and current missions have now demonstrated that water once flowed at the surface of Mars early in its history. Evidence of ancient ponding has been uncovered at scales ranging from a few kilometers to possibly that of the Arctic ocean. Whether life existed on Mars is still unknown; upcoming missions may find critical evidence to address this question in ancient lakebeds as clues about Mars' climate evolution and i...
