Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book explores the once popular idea of 'Flexible Path' in terms of Mars, a strategy that would focus ona mannedorbital mission to Mars's moons rather than the more risky, expensive and time-consuming triptoland humans on theMartian surface. While currently still not the most popular idea, this missionwould takeadvantage of the operational, scientific and engineering lessons to be learned from going to Mars's moons first. Unlike a trip to the planet's surface, an orbital mission avoids the dangers of the deep gravity well of Mars and a very long stay on the surface. This is analogous to Apollo 8 and 10, which preceded the landing on the Moon of Apollo 11. Furthermore, a Mars orbital mission could be achieved at least five years, possibly 10 before a landing mission. Nor would an orbital mission require all of the extra vehicles, equipment and supplies needed for a landing and a stay on the planet for over a year. The cost difference between the two types of missions is in the order of tens of billions of dollars.An orbital mission to Deimos and Phobos would provide an early opportunity to acquire scientific knowledge of the moons and Mars as well, since some of the regolith is presumed to be soil ejected from Mars. It may also offer the opportunity to deploy scientific instruments on the moons which would aid subsequent missions. It would provide early operational experience in the Mars environment without the risk of a landing. The author convincingly argues this experience would enhance the probability of a safe and successful Mars landing by NASA at a later date, and lays out the best way to approach an orbital mission in great detail.Combining path-breaking science with achievable goals on a fast timetable, this approach is the best of both worlds--and our best path to reaching Mars safely in the future.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book explores the practicality of using the existing subsurfacegeology on the Moon and Mars for protection against radiation,thermal extremes, micrometeorites and dust storms rather thanbuilding surface habitats at great expense at least for those first fewmissions. It encourages NASA to plan a precursor mission using thisconcept and employ a 'Short Stay' Opposition Class mission to Mars as thefirst mission rather than the 'Long Stay' concept requiring a mission that istoo long, too dangerous and too costly for man's first missions to Mars.Included in these pages is a short history on the uses of caves by earlyhumans over great periods of time. It then describes the ongoing effortsto research caves, pits, tunnels, lava tubes, skylights and the associatedtechnologies that pertain to potential lunar and Mars exploration andhabitation. It describes evidence for existing caves and lava tubes onboth the Moon and Mars. The work of noted scientists, technologistsand roboticists are referenced and described. This ongoing work is moreextensive than one would think and is directly applicable to longer termhabitation and exploration of the Moon and Mars. Emphasis is also givento the operational aspects of working and living in lunar and Martian cavesand lava tubes.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book describes the history of this now iconic room which represents America's space program during the Gemini, Apollo, Skylab, Apollo-Soyuz and early Space Shuttle eras. It is now aNational Historic Landmark and is being restored to a level which represents the day the flight control teams walked out after the last lunar landing missions.The book is dedicated to the estimated 3,000 men and women who supported the flights and tells the story from their perspective. It describes the rooms of people supporting this control center; those rooms of engineers, analysts and scientists most people never knew about. Some called it a 'shrine' and some called it a 'cathedral.' Now it will be restored to its former glory and soon thousands will be able to view the place where America flew to the moon.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Stratospheric balloons are powerful tools used to study the Earth and its atmosphere, as well as the greater cosmos beyond. This book describes the science and technology behind modern stratospheric ballooning, along with the surprising ways it has impacted our daily lives.The book takes you through every step of the process, starting with an in-depth introduction to basic balloon types and their uses before delving into balloon construction and mission planning. Along the way, you will learn about the novel technologies that have radically changed these balloons and their ability to launch, control and navigate them over specific ground targets. Next follows an exploration of their incredible applications, including research in atmospheric science, cosmology and astronomy, earth studies, meteorology, and aerobiology, and also commercial capabilities such as Internet networks and high-altitude tourism.The community of scientists,engineers, and entrepreneurs involved in stratospheric ballooning is only ever growing. This book shows you how these national and international efforts have truly soared in recent years, and it will be an enjoyable read for anybody interested in learning more about how science and commerce are conducted in the stratosphere, at the edge of space.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This is the comprehensive story of NASA's pioneering Mars 2020 mission, which at this moment continues to break ground on the surface of the Red Planet.The book takes readers through every stage of the Mars mission, describing its major goals and objectives, the cutting-edge technology and instrumentation onboard the Perseverance rover and other spacecraft components, and the members of the scientific team who steered the mission along the way.Mars 2020 is the first to actually take samples of the Red Planet and prepare them for subsequent return to Earth. The chapters therefore delve into how and why Jezero Crater was selected as the optimal landing and sample collecting site to meet the mission objectives. Featuring dozens of high-resolution images of the mission, this book gives readers a deeper understanding of the technology underlying Mars 2020 and why its work is so important for planetary science and space exploration. …
