Hypersonics is the study of flight at speeds where aerodynamic heating dominates the physics of the problem. Typically this is Mach 5 and higher. Hypersonics is an engineering science with close links to supersonics and engine design.Within this field, many of the most important results have been experimental. The principal facilities have been wind tunnels and related devices, which have produced flows with speeds up to orbital velocity.

Hardcover, full-color print.The third edition of the International Space Station Benefits for Humanity is a compilation of benefits being realized from International Space Station (ISS) activities in the areas of human health, Earth observations and disaster response, innovative technology, global education, and economic development of space. This revision also includes new assessments of economic value and scientific value in more detail than the second edition. The third edition contains updated statistics on the impacts of the benefits as well as new benefits that have developed since the previous publication. International Space Station Benefits for Humanity is a product of the ISS Program Science Forum (PSF), which consists of senior science representatives across the ISS international partnership.

Printed in color.The International Space Station (ISS) is the unique blend of unified and diversified goals among the world's space agencies that will lead to improvements in life on Earth for all people of all nations. While the various space agency partners may emphasize different aspects of research to achieve their goals in the use of the ISS, they are unified in several important overarching goals.

Premium color, hardbackThis book stands at an intersection of science and art. From its origins, NASA has studied our planet in novel ways, using ingenious tools to study physical processes at work-from beneath the crust to the edge of the atmosphere. We look at it in macrocosm and microcosm, from the flow of one mountain stream to the flow of jet streams. Most of all, we look at Earth as a system, examining the cycles and processes-the water cycle, the carbon cycle, ocean circulation, the movement of heat-that interact and influence each other in a complex, dynamic dance across seasons and decades.We measure particles, gases, energy, and fluids moving in, on, and around Earth. And like artists, we study the light-how it bounces, reflects, refracts, and gets absorbed and changed. Understanding the light and the pictures it composes is no small feat, given the rivers of air and gas moving between our satellite eyes and the planet below.For all of the dynamism and detail we can observe from orbit, sometimes it is worth stepping back and simply admiring Earth. It is a beautiful, awe-inspiring place, and it is the only world most of us will ever know.NASA has a unique vantage point for observing the beauty and wonder of Earth and for making sense of it. Looking back from space, astronaut Edgar Mitchell once called Earth "a sparkling blue and white jewel," and it does dazzle the eye. The planet's palette of colors and textures and shapes-far more than just blues and whites-are spread across the pages of this book.We chose these images because they inspire. They tell a story of a 4.5-billion-year-old planet where there is always something new to see. They tell a story of land, wind, water, ice, and air as they can only be viewed from above. They show us that no matter what the human mind can imagine, no matter what the artist can conceive, there are few things more fantastic and inspiring than the world as it already is. The truth of our planet is just as compelling as any fiction.We hope you enjoy this satellite view of Earth. It is your planet. It is NASA's mission.

Premium color, hardbackIn 1960, the United States put its first Earth-observing environmental satellite into orbit around the planet. Over the decades, these satellites have provided invaluable information, and the vantage point of space has provided new perspectives on Earth. This book celebrates Earth's aesthetic beauty in the patterns, shapes, colors, and textures of the land, oceans, ice, and atmosphere. Earth-observing environmental satellites can measure outside the visible range of light, so these images show more than what is visible to the naked eye. The beauty of Earth is clear, and the artistry ranges from the surreal to the sublime. Truly, by escaping Earth's gravity we discovered its attraction.Earth as art-enjoy the gallery.
