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 problems ever attempted for design spacecraft to survive the severe cold of deep space, as well as the unforgiving temperature swings on the surface of Mars. This is done without losing sight of the fundamental and classical theories of thermodynamics and structural mechanics that paved the way to more pragmatic and applied methods such finite element analysis and Monte Carlo ray tracing, for example.
Many factors make operating electronics at room temperature on the surface not feasible, including the large mass associated with creating a suitable pressure vessel and the power required to cool it down some 400 °C would make the task daunting. Many of the common electronic packaging materials such as eutectic tin-lead solder, polymerics, wire insulators, and so on could not handle such high temperatures, so a start is to create a list of compatible materials or to eliminate their need all together. The JPL microelectronics division designed a robust solar cell to handle temperatures near 450 °C by carefully selecting the materials. Most IC base materials such as GaAS, GaN, SiO2, and indium phosphide are well suited to withstand the high temperatures because they are ceramics.
Features:
Includes case studies from NASA’s Jet Propulsion Laboratory, which prides itself in robotic exploration of the solar system, as well as flyting the first cubeSAT to Mars.
Enables spacecraft designer engineers to create a design that is structurally and thermally sound, and reliable, in the quickest time afforded.
Examines innovative low-cost thermal and power systems.
Explains how to design to survive rocket launch, the surfaces of Mars and Venus.
Suitable for practicing professionals as well as upper-level students in the areas of aerospace, mechanical, thermal, electrical, and systems engineering, Thermal and Structural Electronic Packaging Analysis for Space and Extreme Environments provides cutting-edge information on how to design, and analyze, and test in the fast-paced and low-cost small satellite environment and learn techniques to reduce the design and test cycles without compromising reliability. It serves both as a reference and a training manual for designing satellites to withstand the structural and thermal challenges of extreme environments in outer space.
