Book Description
'Astonishing' - New Scientist Icy, rocky, sometimes dusty, always mysterious – comets and asteroids are among the Solar System's very oldest inhabitants, formed within a swirling cloud of gas and dust in the area of space that eventually hosted the Sun and its planets. Locked within each of these extra-terrestrial objects is the 4.6-billion-year wisdom of Solar System events, and by studying them at close quarters using spacecraft we can coerce them into revealing their closely-guarded secrets. This offers us the chance to answer some fundamental questions about our planet and its inhabitants. Exploring comets and asteroids also allows us to shape the story of Earth's future, enabling us to protect our precious planet from the threat of a catastrophic impact from space, and maybe to even recover valuable raw materials from them. This cosmic bounty could be as useful in space as it is on Earth, providing the necessary fuel and supplies for humans as they voyage into deep space to explore more distant locations within the Solar System. Catching Stardust tells the story of these enigmatic celestial objects, revealing how scientists are using them to help understand a crucial time in our history – the birth of the Solar System, and everything contained within it.

Book Description
In 1993, the U.S. Department of Defense declassified information dealing with frequent explosions in the upper atmosphere caused by meteoric impact. It is estimated that impacts have occurred of a magnitude equivalent to the atomic bomb detonated at Hiroshima. Not all such space voyagers meet their end in the atmosphere, however; huge craters attest to the bombardment of earth over millions of years, and a major impact may have resulted in the extinction of dinosaurs. An impact in Siberia near the beginning of this century proves that such events are not confined to geologic time. Hazards Due to Comets and Asteroids marks a significant step in the attempt to come to grips with the threats posed by such phenomena. It brings together more than one hundred scientists from around the world, who draw on observational and theoretical research to focus on the technical problems related to all aspects of dealing with these hazards: searching for and identifying hazardous comets and asteroids; describing their statistics and characteristics; intercepting and altering the orbits of dangerous objects; and applying existent technologies—rocket boosters, rendezvous and soft-landing techniques, instrumentation—to such missions. The book considers defensive options for diverting or disrupting an approaching body, including solar sails, kinetic-energy impacts, nuclear explosives, robotic mass drivers, and various propulsion systems. A cataclysmic impact posing a threat to life on Earth is a possibility that tomorrow's technology is capable of averting. This book examines in depth the reality of the threat and proposes practical measures that can be initiated now should we ever need to deal with it.

Book Description
Oumuamua is a space rock that formed around another star. Of the 10,000 space objects that have hurled past our Sun, this rock provides some proof that there are planets similar to Earth outside our solar system. This intriguing book reveals to young space explorers the secrets contained in the rocks that fly around in space.

Book Description
Sample Return Missions: The Last Frontier of Solar System Exploration examines the discoveries and results obtained from sample return missions of the past, present, and future. It analyses the results in the context of the current state of knowledge and their relation to the formation and evolution of planetary bodies, as well as to the available technologies and techniques. It provides detailed descriptions of experimental procedures applied to returned samples. Beginning with an overview of previous missions, Sample Return Missions then goes on to provide an overview of facilities throughout the world used to analyze the returned samples. Finally, it addresses techniques for collection, transport, and analysis of the samples, with an additional focus on lessons learned and future perspectives. Providing an in-depth examination of a variety of missions, with both scientific and engineering implications, this book is an important resource for the planetary science community, as well as the experimentalist and engineering communities. Presents sample return results obtained so far in relation to remote sensing measurements, methods and techniques for laboratory analysis, and technology Provides an overview of a variety of sample return missions, from Apollo, to Hayabusa-2, to future missions Examines technological and methodological advances in analyzing returned samples, as well as the resources available globally
