Marking the anniversary of the telescope’s invention, these collected essays highlight a number of significant historical episodes concerning this well-loved instrument, which has played a crucial role in Man’s thinking about his position – literally and philosophically – in the universe.

Viewing the Earth examines the role played by interest groups in shaping the process of technological change, offering valuable insights into how technologies evolve. It traces the history of Landsat from its origins through the launch and use of the first few satellites, showing how a variety of forces shape the form and the eventual reception of any new technology. The Landsat earth resources satellite system was a project of The National Aeronautics and Space Administration that was created to collect data about earth resources from space. The first satellite was launched in 1972 with great fanfare and high expectations. The data proved useful for everything from finding oil to predicting harvests, yet today the successful commercialization of the program is still uncertain. Why? To answer this question, Pamela E. Mack focuses on the negotiating process that went on among different parts of the space agency, other interested government agencies, and various organizations that were potential users of the data. This formal and informal negotiating process, she points out, involved not only choices between alternative technologies and the satellite but also conflicting definitions of what the satellite would do. The story is full of fascinating detail, from the concerns of the intelligence community over civilian satellites looking at the earth to the politics of agricultural survey. Pamela E. Mack is Associate Professor in the History Department at Clemson University.

Evidence from Earth Observation Satellites is an edited collection analysing emerging legal issues surrounding the use of satellite data as evidence. It considers whether data from satellite technologies can be a legally reliable, effective evidential tool in contemporary legal systems.

A step-by-step guide to predicting and calculating the positions of stars, planets, the sun, the moon, and satellites using a personal computer and high school mathematics—for amateur astronomers Our knowledge of the universe is expanding rapidly, as space probes launched decades ago begin to send information back to earth. There has never been a better time to learn about how planets, stars, and satellites move through the heavens. This book is for amateur astronomers who want to move beyond pictures of constellations in star guides and solve the mysteries of a starry night. It is a book for readers who have wondered where Saturn will appear in the night sky, when the sun will rise and set—or how long the space station will be over their location. In Celestial Calculations, J. L. Lawrence shows readers how to find the answers to these and other astronomy questions with only a personal computer and high school math. Using an easy-to-follow step-by-step approach, Lawrence explains what calculations are required, why they are needed, and how they all fit together. Lawrence begins with basic principles: unit of measure conversions, time conversions, and coordinate systems. He combines these concepts into a computer program that can calculate the location of a star and uses the same methods for predicting the locations of the sun, moon, and planets. He then shows how to use these methods for locating the many satellites we have sent into orbit. Finally, he describes a variety of resources and tools available to the amateur astronomer, including star charts and astronomical tables. Diagrams illustrate the major concepts, and computer programs that implement the algorithms are included. Photographs of actual celestial objects accompany the text, and interesting astronomical facts are interspersed throughout. Source code (in Python 3, JAVA, and Visual Basic) and executables for all the programs and examples presented in the book are available for download at https://CelestialCalculations.github.io.

Something SMALL is wrong with physics if we look at the Hubble images of our universe. This and other anomalies described in the book are a firm reason to suggest a PARADIGM SHIFT, which could lead to a TOE. (Theory Of Everything)I hope you will enjoy the reading of this book. HOWEVER I also hope that you will be able to grasp the speculative logic of my "Goals of intelligent life" postulation.Why? because:If we don't feed the "have nots" and keep them in endless poverty, the STP-ROM or Global (collective) consciousness around Mother Earth, which is supposed to be the base for all our dreams and intuition, will turn into a steep negative spiral.This could be the origin of a strong global hatred and the rise of fascist leaders.

The ground segment is the fundamental backbone of every satellite project, yet it is usually not visible to the public or the end user of a satellite service. Also the bulk of existing published space literature tends to focus on the satellite or its subsystems. This book tries to fill this gap and addresses systems engineering concepts applied to the design, development, qualification, and deployment of the ground control segment required to operate a single satellite, a constellation, or even a manned space vehicle. The domain of ground segment engineering has significantly evolved in recent years, mainly driven by major advances in the IT sector. Hardware virtualisation or the availability of on-demand cloud computing services are typical examples of new technologies that have changed fundamental architectural concepts previously standard in heritage ground segments. Furthermore, the stark increase of cyber attacks - today a major risk to almost all critical IT based infrastructure - has made a cyber threat resilient architecture to become one of the indispensable design requirements for ground segment engineers. The new mega constellations recently put into space deploying up to several hundred of flying objects have put very demanding needs on the ground segment for automated satellite operations. These topics and more are addressed in the book’s chapters, along with a detailed explanation of the most relevant components of a typical ground segment architecture. The basic functional requirements, design features, and the most important ground and space segment interfaces are addressed and explained in detail, supported by a wealth of figures for easier understanding. This book is kept at an introductory level, allowing newcomers to get familiar with this fairly complex subject matter. It is therefore suitable for graduate students, but can equally serve as a valuable source of information for already experienced space engineers who seek to gain a deeper understanding of the ground segment infrastructure and related systems engineering processes. It can also help project managers to better interact with their systems engineers, satellite developers to define their ground segment interfaces, and satellite operators to improve their flight and ground procedures. It is very well suited for everyone intending to start a career in satellite ground segment systems engineering.
