Zustand: Very Good. Overall, very good condition. This new book from the NASA History Series tackles an interesting duo of biological problems that will be familiar to anybody who has seen photos of Apollo astronauts quarantined after their return to Earth. Namely, how do we avoid contaminating celestial bodies with Earthly germs when we send spacecraft to study these bodies, and how do we avoid spreading foreign biological matter from space when our robotic and human spacefarers return to Earth?Biological matter from an external system could potentially cause an unchecked epidemic either on Earth or in space so strict precautions are necessary. Each time a space vehicle visits another world it runs the risk of forever changing that extraterrestrial environment. We are surrounded on Earth by a melange of different microorganisms, and if some of these hitchhike onboard a space mission, they could contaminate and start colonies on a different planet. Such an occurrence would irrevocably alter the nature of that world, compromise all future scientific exploration of the body, and possibly damage any extant life on it. By inadvertently carrying exotic organisms back to Earth on our spacecraft, we also risk the release of biohazardous materials into our own ecosystem. Such concerns were recognized by scientists even before the 1957 launch of Sputnik. This book presents the history of planetary protection by tracing the responses to the above concerns on NASA s missions to the Moon, Mars, Venus, Jupiter, Saturn, and many smaller bodies of our solar system. The book relates the extensive efforts put forth by NASA to plan operations and prepare space vehicles that return exemplary science without contaminating the biospheres of other worlds or our own. To protect irreplaceable environments, NASA has committed to conducting space exploration in a manner that is protective of the bodies visited, as well as of our own planet.".…

Zustand: Very Good. Biography of William H. Pickering, 1910-2004 On the first day of February 1958, three men held aloft a model of Explorer 1, America's first Earth satellite, for the press photographers. That image of William Pickering, Wernher von Braun, and James Van Allen became an icon for America's response to the Sputnik challenge. Von Braun and Van Allen were well known, but who was Pickering? From humble beginnings in a remote country town in New Zealand, Pickering came to California in 1928 and quickly established himself as an outstanding student at the then-new California Institute of Technology (Caltech). At Caltech, Pickering worked under the famous physicist Robert Millikan on cosmic-ray experiments, at that time a relatively new field of physics. In 1944, when Caltech's Jet Propulsion Laboratory (JPL) was developing rocket propulsion systems for the U. S. Army, Pickering joined the work-force as a technical manager. He quickly established himself as an outstanding leader, and 10 years later, Caltech named him Director of JPL. And then, suddenly, the world changed. In October 1957, the Sputnik satellite startled the world with its spectacular demonstration of Soviet supremacy in space. Pickering led an intense JPL effort that joined with the von Braun and Van Allen teams to answer the Soviet challenge. Eighty-three days later, on 31 January 1958, America's first satellite roared into Earth orbit. A few months after that, Pickering's decision to affiliate JPL with the newly formed National Aeronautics and Space Administration set the basis for his subsequent career and the future of NASA's ambitious program for the exploration of the solar system. In the early days of the space program, failure followed failure as Pickering and his JPL team slowly ascended the "learning curve." Eventually, however, NASA and JPL resolve paid off. First the Moon, then Venus, and then Mars yielded their scientific mysteries to JPL spacecraft of ever-increasing sophistication. Within its first decade, JPL-built spacecraft sent back the first close-up photographs of the lunar surface, while others journeyed far beyond the Moon to examine Venus and return the first close-up views of the surface of Mars. Later, even more complex space missions made successful soft-landings on the Moon and on Mars. Pickering's sudden death in March 2004 at the age of 93 was widely reported in the U. S. and overseas. As one NASA official eulogized him, "His pioneering work formed the foundation upon which the current program for exploring our solar system was built." On this, the 50th anniversary of the beginning of the Space Age, it is proper to remind ourselves of the ordinary people who met the extraordinary challenge to make it happen.
