Set against the backdrop of the 1960s and 1970s space exploration, the narrative delves into NASA's evolving strategies for deep space missions. Initially, missions were launched in pairs for safety, but after the successful Viking landings on Mars and the Voyagers' exploration of the outer planets, a shift occurred. The decision to reduce costs led to the launch of single probes, marking a significant change in approach to space exploration during this pivotal era.
Exploring the mysteries of the second largest moon in our solar system, this account delves into its unique geological features, atmospheric conditions, and potential for harboring life. The narrative combines scientific insights with captivating imagery, offering readers a comprehensive understanding of this celestial body’s significance in the broader context of space exploration and planetary science.
A fascinating insight into a place within our own solar system where there are
very similar conditions to those on ancient Earth, and where scientists are
planning to send new and innovative exploratory probes, as they believe there
is a possibility of discovering primitive forms of life, and of learning more
about the development of early Earth.
This book explores the functioning of sand dunes, their diverse formations across various environments, and contemporary research surrounding them, including their presence on other celestial bodies. It highlights the dynamic nature of dune science, paralleling the ever-changing characteristics of dunes themselves, and boasts striking visuals of Aeolian geomorphology. The text is structured into four parts. The first introduces dunes as a planetary phenomenon, reflecting geological processes like volcanism, impact, tectonics, erosion, and sediment deposition. It examines dunes as emergent dynamical systems shaped by the interplay of sand and wind, drawing parallels with other emergent structures. The impact of dunes on desert communities and infrastructure is discussed, alongside their role as forensic climatological indicators. The physics of dunes is analyzed, covering sand mechanics, wind physics, and dune morphology classification. The second part surveys Earth, Mars, Titan, and other celestial bodies, starting with Earth's major deserts and dunefields. It delves into Mars' environment, sediment types, dune stratigraphy, and the relationship between dunes and topography. Titan's unique conditions, including its thick atmosphere and methane presence, are examined, along with the implications for climate and wind patterns. The section concludes with a look at other planetary bodies, noting the limited dunefields on Venus and
Die Kursinhalte der Fortbildungskurse HERNIE kompakt , HERNIE konkret und HERNIE komplex – jetzt endlich als Buch! Das Buch zur Hernienschule gibt einen grundlegenden praktisch orientierten und systematischen Überblick über die gegenwärtige Hernienchirurgie. Es versteht sich als Ergänzung zu den bereits bestehenden stufenartig aufgebauten Fortbildungskursen der Deutschen Herniengesellschaft (DHG) und der BDC-Akademie. Sowohl internationale als auch nationale Hernienspezialisten beschreiben dabei alle relevanten aber auch neueste OP-Techniken erstmals im Sinne eines Standards in wichtigen Einzelschritten. Die Autoren ergänzen dies um ihre ganz persönlichen Erfahrungen und Vorgehensweisen mit Tipps und Tricks und stellen den aktuellen Stand der Wissenschaft dar. Das Buch richtet sich an Ärztinnen und Ärzte in Weiterbildung zum Allgemein- und Viszeralchirurgen, aber auch an alle Chirurgen, die sich in der Hernienchirurgie auf den neuesten Stand bringen möchten.
