Have you ever wondered how NASA designs, builds, and tests spacecrafts and hardware for space? How is it that wildly successful programs such as the Mars Exploration Rovers could produce a rover that lasted over ten times the expected prime mission duration? Or build a spacecraft designed to visit two orbiting destinations and last over 10 years when the fuel ran out? This book was written by NASA/JPL engineers with experience across multiple projects, including the Mars rovers, Mars helicopter, and Dawn ion propulsion spacecraft in addition to many more missions and technology demonstration programs. It provides useful and practical approaches to solving the most complex thermal-structural ...
The endurance time method (ETM) is a seismic analysis procedure in which intensifying dynamic excitations are used as the loading function, and it provides many unique benefits in the design of structures. It can largely reduce the computational effort needed for the response history analysis of structures. This aids in the practical application of response history-based analysis in problems involving very large models and/or requiring numerous analyses to achieve optimal design goals. A single response history analysis through ETM provides an estimate of the system response at the entire range of seismic intensities of interest, thus making it ideal for applications such as seismic risk ass...
Environmental sustainability efforts require a great deal of engagement and political will, ranging from local communities to state departments. Science diplomats—from experts and scientists to spokespersons and ambassadors—can help facilitate at all levels and yield valued resources from technology sharing, capacity building, and knowledge exchanges. This book explores the importance of sustained international scientific cooperation, building community resilience, and the role of political will in sustainability and diplomacy. It shows how even small diplomatic efforts can influence myriad issues, from overfishing to human rights negotiations to global carbon emission reduction. Feature...
