Orbiting Eyes
When you look up at the night sky, do you ever wonder why some stars seem to move? These moving lights are not stars. They are artificial satellites, machines put into space to help us communicate or gather information here on Earth. From the launch of the first artificial satellite in 1957 to the space telescopes making headlines today, these orbiting eyes have helped us study the heavens, survey the earth, stay in touch, and protect our homelands. Headline Science uses news stories and everyday applications to explain the science behind artificial satellites.
The Use of Artificial Satellites for Geodesy
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 15. This monograph contains 34 communications presented at the Third International Symposium on the Use of Artificial Satellites for Geodesy in 1971, and 4 invited papers on subjects that complement the others and provide continuity. All contributions represent the most recent findings in the theoretical and applied fields of satellite geodesy, including new instrumentation (satellite sensors and ground equipment) of potential use in satellite geodesy. The two preceding symposiums were held at Washington, D.C., in 1962 and at Athens, Greece, in 1965. The Proceedings of the first were published by North-Holland Publishing Company, Amsterdam, in 1963, and the Proceedings of the second by the National Technical University, Athens, in 1967. The prime mover behind both was George Veis, and his continuing dedication to this subject was in large measure responsible for scheduling this third symposium.

America's Leap Into Space
After the shock of watching Russia's Sputnik become the world's first artificial satellite, America's infant space program hurried to launch one of their own. In just 90 days, Dr. Henry Richter and his colleagues at the Jet Propulsion Laboratory developed and launched the nation's response. Through innovation, teamwork, and tenacity, these pioneering scientists and engineers began America's exploration of space that continues to determine our place in the cosmos. JPL and the First Explorer Satellites tracks the development of the Russian, Germany, and American rocketry programs through the World Wars and into the arms race of the Cold War. Dr. Richter's memories and extensive research shed a light into the earliest days of the space age. It is a fascinating story that is equal parts memoir and insider history of one of the world's most dynamic and revolutionary periods....
Satellite
Right now, above our heads—nearly imperceptible to us but hugely important to how we live—are thousands of man-made objects that we have sent into space. Ubiquitous but mysterious, satellites are the technological infrastructure of our globally connected world, helping us do everything from orient ourselves on a map to watch our favorite television shows. Yet we rarely ever think about them. In this book, Doug Millard pays overdue tribute to the stoic existence of the satellite, tracing its simultaneous pathways through the cold silence of space and the noisy turbulence of the past century. How satellites ever came to be is, in itself, a remarkable story. Telling an astonishing history o...
Artificial Satellites and How to Observe Them
Every amateur astronomer - and many non-astronomers - will be familiar with seeing a "star" that shows that characteristic steady slide across the starry background of the sky. Artificial satellites can be seen any night, and some as bright as the planets. But how many of us can identify which satellites or spent launch vehicle casing we are seeing? Artificial Satellites and How to Observe Them describes all the different satellites that can be observed without optical aid, including of course the International Space Station and the many spy satellites operated by different nations. Richard Schmude looks at them in detail and describes how they can be observed by amateurs, how to recognize t...
Selfies from Space
Satellites may exist out in space, but they let us study Earth from the outside looking in. From climate change to natural disasters and more, find out how scientists are using satellites to tackle some of our world's most challenging problems.
