In the span of a single lifetime, light pollution stemming from Artificial Light At Night (ALAN) has severed our connection with the stars that we've had since the dawn of time. With the nocturnal biosphere significantly altered, light's anthropogenic influence has compelled millions of people to seek out the last remaining dark skies. This book explores the burgeoning growth of the astrotourism market, identifies star seeker trends, how the stars have shaped civilizations, and the budding space tourism industry. Discover ways to develop a destination for those who will cater to the astrotourist, share the night with guests, how to find customers, and the 2024 Great North American Eclipse. Meteor storms, eclipses, auroras, and other celestial phenomena have lured travellers for years. Here, the author expands the field of astrotourism with the inclusion of astronomical clocks, megaliths, and sundials, which are used to track the movement of the stars.

The Mars Curiosity Rover is the most sophisticated mobile laboratory ever deployed on a planet. For over seven years, scores of investigators have planned its daily route and activities, poring over the overwhelming images and data and revising our understanding of planetary surfaces, geology, and potential habitability. This book takes readers right down to the surface of Mars, chronicling Curiosity's physical and scientific journey across the planet's Earth-like, yet strikingly alien vistas. Through dozens of images and descriptive accounts of the surface, you will gain a deeper knowledge of the Martian landscape, from the floor of Gale Crater up to the cliffs of Mount Sharp. Presented at the end of each chapter are the results and revelations from the science team spearheading the mission. Like any cross-country road trip, the rover has hit some unexpected hitches along the way. The book describes the obstacles faced by the rover and its scientists over the years and the difficult decisions and careful experimentation it took to solve them.

At 7:15 a.m. on October 3, 1962, Project Mercury Astronaut Walter M. Schirra, Jr., in his Sigma 7 spacecraft, was launched into space and orbited the Earth six times, completing another step in the grand U.S. program to send a man to the Moon and then return him safely to Earth. Because of the brief durations of the previous Mercury flights, the astronauts spent the majority of their flight time in getting to orbit and preparing to leave orbit. Schirra's six-orbit mission lasted more than nine hours, which for the first time allowed an astronaut to experience an extended period of weightlessness. In addition, the time available allowed Schirra to engage in orbital manoeuvring, exercising the various manual and automatic control modes, and to spend time on photography and scientific experiments. After his return to the United States, Schirra described his Sigma 7 mission as "a text book flight." A compilation of inputs from engineering, operations and medical personnel had been integrated into a single flight plan, which Schirra then carried out exactly as he had trained.;The unqualified success of this flight paved the way for the planned upcoming one-day mission, an important milestone on the journey to the Moon. In this book the Mission Press Kit and press releases are combined with the major post-mission reports to provide a comprehensive picture of the flight from the planning stages through to its successful completion. Sigma 7 - The NASA Mission Reports is taken directly from the NASA archives. It presents the details of the Mercury-Atlas 8 mission, the overall Project Mercury game plan, astronaut Walter M. Schirra, Jr., and all of the many professional support people and facilities that went into making the mission a complete success. Includes a CD-ROM featuring: An exclusive interview with Mercury Astronaut Walter M. Schirra, Jr; The NASA movie - Flight of Sigma 7; NASA movie - Unmanned Mercury Missions; NASA Document (pdf) - Space Medicine in Project Mercury.

In the 1940s and 50s, when the newly minted Jet Propulsion Laboratory needed quick-thinking mathematicians to calculate velocities and plot trajectories, they recruited an elite group of young women who, with only pencil, paper, and mathematical prowess, transformed rocket design, helped bring about the first American satellites, and made the exploration of the solar system possible. Rise of the Rocket Girls tells the stories of these women--known as "human computers"--who broke the boundaries of both gender and science. Based on extensive research and interviews, Nathalia Holt offers a unique perspective on the role of women in science: both where we've been, and the far reaches of space to which we're heading.

This book will certainly help them be ready for such a journey. Most importantly, it explains not only what happened 50 years ago, but how the Apollo missions happened, and the science that is required to do it again, or to go further, to Mars. If the reader is younger, still in school and perhaps considering the sciences, this book will introduce ideas that will help you choose the subjects to study which can help you to make your space travel a reality. For others, the book will be an exciting and thought provoking read that gives a vision of the near future in space, which all of us on planet Earth will be able to enjoy as the adventure unfolds."- Michael Foale, CBE, former-NASA astronaut

Whether you're interested in visiting Apollo landing sites or the locations of classic sci-fi movies, this is the tourist guide for you! This tourist guide has a twist - it is a guide to a whole different world, which you can visit from the comfort of your backyard with the aid of nothing more sophisticated than an inexpensive telescope. It tells you the best times to view the Moon, the most exciting sights to look out for, and the best equipment to use, allowing you to snap stunning photographs as well as view the sights with your own eyes. Have you ever been inspired by stunning images from the Hubble telescope, or the magic of sci-fi special effects, only to look through a small backyard telescope at the disappointing white dot of a planet or faint blur of a galaxy? Yet the Moon is different. Seen through even a relatively cheap 'scope, it springs into life like a real place, with mountains and valleys and rugged craters. With a bit of imagination, you can even picture yourself as a sightseeing visitor there - which in a sense you are.

Christopher A. Roosa grew up the eldest son of Apollo 14 astronaut and command module pilot Stuart A. Roosa. As a child of the space program, Christopher had a ringside seat at the dinner table of one of twenty-four Americans who had either entered lunar orbit or landed on the moon. The first book written by an offspring of an Apollo astronaut to focus on growing up in that era, Son of Apollo tells the inside story of the life of his father, a man who had a remarkable career despite always believing his air force career was "off-track," from his initial application to the service to his removal from the prime crew of Apollo 13 and his subsequent assignment to Apollo 14. During the Apollo 13 mission and recovery, Stuart played an integral role in developing the procedures to return the crew to Earth safely. The focus-and the pressure-of the entire Apollo program then shifted to the Apollo 14 mission. If the Apollo program was to continue, Stuart and the Apollo 14 crew would need to get safely to the moon, land, and return. In writing about his father's career, Christopher Roosa also shows us a familial side of the Apollo experience, from the daily struggles of growing up in the shadow of a father who was necessarily away in training most of the year to the expectations involved in being an astronaut's son. Roosa's story shows the Apollo era was the result not only of thousands of scientists and engineers working steadfastly toward achieving an assassinated president's national goal but also the families who supported them and lived the missions in their own way.

How does one go about organizing something as complicated as a strategic-missile or space-exploration program? Stephen B. Johnson here explores the answer--systems management--in a groundbreaking study that involves Air Force planners, scientists, technical specialists, and, eventually, bureaucrats. Taking a comparative approach, Johnson focuses on the theory, or intellectual history, of "systems engineering" as such, its origins in the Air Force's Cold War ICBM efforts, and its migration to not only NASA but the European Space Agency.

Exploring the history and politics of aerospace development and weapons procurement, Johnson examines how scientists and engineers created the systems management process to coordinate large-scale technology development, and how managers and military officers gained control of that process. "Those funding the race demanded results," Johnson explains. "In response, development organizations created what few expected and what even fewer wanted--a bureaucracy for innovation. To begin to understand this apparent contradiction in terms, we must first understand the exacting nature of space technologies and the concerns of those who create them."

Once the United States landed on the moon in July 1969, it was up to President Nixon to decide what to do in space after Apollo. This book chronicles the decisions he made, including ending space exploration and approving the space shuttle. Those decisions determined the character of the US human space flight program for the next forty years.

Provides the basics of spacecraft orbital dynamics plus attitude dynamics and control, using vectrix notation

"Spacecraft Dynamics and Control: An Introduction" presents the fundamentals of classical control in the context of spacecraft attitude control. This approach is particularly beneficial for the training of students in both of the subjects of classical control as well as its application to spacecraft attitude control. By using a physical system (a spacecraft) that the reader can visualize (rather than arbitrary transfer functions), it is easier to grasp the motivation for why topics in control theory are important, as well as the theory behind them. The entire treatment of both orbital and attitude dynamics makes use of vectrix notation, which is a tool that allows the user to write down any vector equation of motion without consideration of a reference frame. This is particularly suited to the treatment of multiple reference frames. Vectrix notation also makes a very clear distinction between a physical vector and its coordinate representation in a reference frame. This is very important in spacecraft dynamics and control problems, where often multiple coordinate representations are used (in different reference frames) for the same physical vector.Provides an accessible, practical aid for teaching and self-study with a layout enabling a fundamental understanding of the subjectFills a gap in the existing literature by providing an analytical toolbox offering the reader a lasting, rigorous methodology for approaching vector mechanics, a key element vital to new graduates and practicing engineers alikeDelivers an outstanding resource for aerospace engineering students, and all those involved in the technical aspects of design and engineering in the space sectorContains numerous illustrations to accompany the written text. Problems are included to apply and extend the material in each chapter

Essential reading for graduate level aerospace engineering students, aerospace professionals, researchers and engineers.

This book discusses the physics of conductive channel development in space, air and vacuums and summarizes the attempts to create super-long conductive channels to study the upper atmosphere and to complete specific tasks related to energy transmission from the space to earth with high-voltage high repetition rate electrical sources. Conductive channels are produced by the laser jet engine vehicle-propulsion under the influence of powerful high repetition rate pulse-periodic laser radiation by CO2-laser, solid state Nd YAG,HF/DF laser systems generated with each pulse of the powerful laser conductive dust plasma. The book also presents the experimental and theoretical results of conductive canal modeling: the laser jet engine vehicle "Impulsar", which can reach the lower layers of the ionosphere in several hundred seconds. Further, the book explores the development of lightning protection systems. The so-called long laser spark is generated to provide the conditions for connecting a thunderstorm cloud with a grounded metal rod, i.e. a classical lightning rod. Such conductivity channels can be used for energy transmission, overvoltage protection systems, transport of charged particle beams and plasma antennas. It provides the theoretical and experimental basis of high repetition rate P-P mode of operation for high power lasers (COIL, HF/DF, CO2,Nd YAG). It describes high efficiency and excellent beam quality disk lasers used for numerous applications, including surface treatment of dielectric materials in microelectronics, cutting, drilling, welding, polishing and cleaning of the surface and other technological operations. Lastly it investigates how megawatt mono-module disk lasers could be used to solve various problems: small satellites launched by lasers, formation of super-long conducting channels in space and atmosphere, cleaning of the near-earth space from the space debris and related applications.

This contributed volume arose from the idea of assembling scientists from space research and ground development, time transfer techniques and radio science missions, the time-frequency community, and both the geodesy-geophysics and solar system exploration communities. Such a fusion of diverse interests in these fields related to time measurement has rarely, if ever, been achieved. The topics covered in these papers include clocks, time transfer, technology, and the applications of high-precision clocks in Earth Sciences, Fundamental Physics, Astrophysics, and Solar System exploration. This book will be of major interest to all those involved in the implementation and utilization of space-based high precision timing for a wide range of applications. Originally published in Space Science Reviews in the Topical Collection "High Performance Clocks with Special Emphasis on Geodesy and Geophysics and Applications to Other Bodies of the Solar System"

This is a book about rocket science: what it is and what it does. From the earliest fireworks to nuclear-powered spacecraft, all you would ever want or need to know about the subject is here, along with a straightforward explanation of how, why and when things work-or sometimes don't. We begin with the history and workings of early terrestrial rocketry before moving onto the main subject of the book: how we get things into space and, on occasion, back again. Entirely math-free, the chapters weave together innumerable anecdotes, real-world examples, and easy walk-throughs to help readers break down the complex physics behind some of humankind's most amazing feats. Neither a pure textbook nor a populist space travel tome, the book will educate, inform and above all entertain anyone intrigued by rocket science.

Featuring over seventy images from the heroic age of space exploration, Through Astronaut Eyes presents the story of how human daring along with technological ingenuity allowed people to see the Earth and stars as they never had before. Photographs from the Mercury, Gemini, and Apollo programs tell powerful and compelling stories that continue to have cultural resonance to this day, not just for what they revealed about the spaceflight experience, but also as products of a larger visual rhetoric of exploration. The photographs tell us as much about space and the astronauts who took them as their reception within an American culture undergoing radical change throughout the turbulent 1960s. This book explores the origins and impact of astronaut still photography from 1962 to 1972, the period when human spaceflight first captured the imagination of people around the world. Photographs taken during those three historic programs are much admired and reprinted, but rarely seriously studied. This book suggests astronaut photography is particularly relevant to American culture based on how easily the images were shared through reproduction and circulation in a very visually oriented society. Space photography's impact at the crossroads of cultural studies, the history of exploration and technology, and public memory illuminates its continuing importance to American identity.

Orbital Mechanics for Engineering Students, Fourth Edition, is a key text for students of aerospace engineering.

Highly illustrated and fully supported with downloadable MATLAB algorithms for project and practical work, this book provides all the tools needed to fully understand the subject.

A NASA insider tells the exciting story of robotic space missions to explore the solar system. Exploring the planets has been a goal of America's space program since the dawn of the space race. This insider's perspective examines incredible missions of robotic spacecraft to every corner of our solar system and beyond. Some were flown into glory, while others were planned and relegated to dusty filing cabinets. All were remarkable in their aspirations. Award-winning science writer Rod Pyle profiles both the remarkable spacecraft and the amazing scientists and engineers who made them possible. From the earliest sprints past Venus and Mars to Voyager1's current explorations of the space between the stars, this exciting book sheds new light on ever-more ambitious journeys designed to increase the human reach into the solar system. Drawing on his perspective as a writer for NASA's Jet Propulsion Laboratory, ground zero for NASA's planetary exploration, the author further details plans now in development to look for signs of life on Jupiter's moon Europa, submarines that will dive into the hazy hydrocarbon lakes of Saturn's moon Titan, and intelligent spacecraft that will operate for months without human intervention on Mars and in the outer solar system well into the 2030s. Equally compelling are programs of exploration that were considered but never left the drawing board, such as automobile-sized biology laboratories designed for a Mars landing in the 1960s and plans to detonate atomic bombs on the moon. Complemented by many rarely-seen photos and illustrations, these stories of incredible engineering achievements, daring imaginations, and technological genius will fascinate and inspire.

In the late 20th and beginning 21st century high-precision astronomy, positioning and metrology strongly rely on general relativity. Supported by exercises and solutions this book offers graduate students and researchers entering those fields a self-contained and exhaustive but accessible treatment of applied general relativity. The book is written in a homogenous (graduate level textbook) style allowing the reader to understand the arguments step by step. It first introduces the mathematical and theoretical foundations of gravity theory and then concentrates on its general relativistic applications: clock rates, clock sychronization, establishment of time scales, astronomical references frames, relativistic astrometry, celestial mechanics and metrology. The authors present up-to-date relativistic models for applied techniques such as Satellite LASER Ranging (SLR), Lunar LASER Ranging (LLR), Globale Navigation Satellite Systems (GNSS), Very Large Baseline Interferometry (VLBI), radar measurements, gyroscopes and pulsar timing. A list of acronyms helps the reader keep an overview and a mathematical appendix provides required functions and terms.

This book presents Special Relativity in a language accessible to students while avoiding the burdens of geometry, tensor calculus, space-time symmetries, and the introduction of four vectors. The search for clarity in the fundamental questions about Relativity, the discussion of historical developments before and after 1905, the strong connection to current research topics, many solved examples and problems, and illustrations of the material in colloquial discussions are the most significant and original assets of this book. Importantly for first-time students, Special Relativity is presented such that nothing needs to be called paradoxical or apparent; everything is explained. The content of this volume develops and builds on the book Relativity Matters (Springer, 2017). However, this presentation of Special Relativity does not require 4-vector tools. The relevant material has been extended and reformulated, with additional examples and clarifications. This introduction of Special Relativity offers conceptual insights reaching well beyond the usual method of teaching relativity. It considers relevant developments after the discovery of General Relativity (which itself is not presented), and advances the reader into contemporary research fields. This presentation of Special Relativity is connected to present day research topics in particle, nuclear, and high intensity pulsed laser physics and is complemented by the current cosmological perspective. The conceptual reach of Special Relativity today extends significantly further compared even to a few decades ago. As the book progresses, the qualitative and historical introduction turns into a textbook-style presentation with many detailed results derived in an explicit manner. The reader reaching the end of this text needs knowledge of classical mechanics, a good command of elementary algebra, basic knowledge of calculus, and introductory know-how of electromagnetism.

Concludes each chapter with examples of past and current orbiting sensors such as DSP, SBIRS, CHAMP, LANDSAT, and GOES to illustrate how concepts are applied. Includes the Matlab codes used to create the example plots in order to give the reader a starting point for further analysis

"Spacecraft Sensors" is an invaluable resource for engineers, technical consultants, those in the business division, and research scientists associated with spacecraft projects. It is also an excellent textbook for undergraduate and postgraduate students studying the development, design and applications of spacebased sensors.

Remote Sensing is the method of measurement of the object properties on the Earth's surface using data acquired from aircraft and satellites. This method makes it possible to carry out the measurement from the distance for the purpose of this research and to display those measurements over a two-dimensional spatial grid, i.e. images. Remote Sensing method, which is based on the data accessed from satellites, provides an opportunity to observe and monitor the Earth, collect appropriate information with further processing and integration of the Geographic Information System. This book's aim is to reveal the opportunities of the application of Remote Sensing and Geographic Information System advances in wide areas of engineering applications through analyzing its own achievements and challenges as well as creative sources existing in the indicated area. This book examines the conceptual aspects of Remote Sensing and Geographic Information System. Its applications are based on implemented projects and its outcomes found a perfect reliable place in the field of engineering.

Spacecraft Dynamics and Control: The Embedded Model Control Approach provides a uniform and systematic way of approaching space engineering control problems from the standpoint of model-based control, using state-space equations as the key paradigm for simulation, design and implementation. The book introduces the Embedded Model Control methodology for the design and implementation of attitude and orbit control systems. The logic architecture is organized around the embedded model of the spacecraft and its surrounding environment. The model is compelled to include disturbance dynamics as a repository of the uncertainty that the control law must reject to meet attitude and orbit requirements within the uncertainty class. The source of the real-time uncertainty estimation/prediction is the model error signal, as it encodes the residual discrepancies between spacecraft measurements and model output. The embedded model and the uncertainty estimation feedback (noise estimator in the book) constitute the state predictor feeding the control law. Asymptotic pole placement (exploiting the asymptotes of closed-loop transfer functions) is the way to design and tune feedback loops around the embedded model (state predictor, control law, reference generator). The design versus the uncertainty class is driven by analytic stability and performance inequalities. The method is applied to several attitude and orbit control problems.
