This essential book describes the mathematical formulations and subsequent computer simulations required to accurately project the trajectory of spacecraft and rockets in space, using the formalism of optimal control for minimum-time transfer in general elliptic orbit. The material will aid research students in aerospace engineering, as well as practitioners in the field of spaceflight dynamics, in developing simulation software to carry out trade studies useful in vehicle and mission design. It will teach readers to develop flight software for operational applications in autonomous mode, so to actually transfer space vehicles from one orbit to another. The practical, real-life applications discussed will give readers a clear understanding of the mathematics of orbit transfer, allow them to develop their own operational software to fly missions, and to use the contents as a research tool to carry out even more complex analyses.

Designing a habitat for the lunar surface? You will need to know more than structural engineering. There are the effects of meteoroids, radiation, and low gravity. Then there are the psychological and psychosocial aspects of living in close quarters, in a dangerous environment, far away from home. All these must be considered when the habitat is sized, materials specified, and structure designed. This book provides an overview of various concepts for lunar habitats and structural designs and characterizes the lunar environment - the technical and the nontechnical. The designs take into consideration psychological comfort, structural strength against seismic and thermal activity, as well as internal pressurization and 1/6 g. Also discussed are micrometeoroid modeling, risk and redundancy as well as probability and reliability, with an introduction to analytical tools that can be useful in modeling uncertainties.

Solar activity has become of increasing importance in our modern society, as many aspects of today's technology could be affected by eruptive phenomena associated with solar magnetic variability. State of the art solar instrumentation is revealing the dynamics of the Sun with unprecedented temporal and spatial resolutions. This volume includes recent results in solar physics research presented at the IAU Symposium 327, the first IAU symposium held in Colombia, in the historical city of Cartagena de Indias, one of the oldest in the Americas. Its main scientific goal was to discuss recent results on the processes shaping the structure of the solar atmosphere and driving plasma eruptions and explosive events in our star. Researchers in both theory and observation, who study structure and activity in the solar atmosphere, discuss a wide range of topics in the field.

'Brilliant. You won't find a clearer, more engaging guide to what we know (or would like to know) about the universe and how it is put together' Bill Bryson Celebrated physicist and global bestselling author Paul Davies tells the story of the universe in thirty cosmological conundrums In the constellation of Eridanus there lurks a cosmic mystery. It's as if something has taken a huge bite out of the universe, leaving a super-void. What could be the culprit? A super massive black hole? Another, bigger universe? Or an expanding vacuum bubble, destined to envelop and annihilate everything in existence? Scientists now understand the history of our universe better than the history of our own planet, but they continue to uncover startling new riddles-the hole in the universe being just one. In this electrifying book, award-winning physicist Paul Davies walks us through the puzzles and paradoxes that have preoccupied cosmologists from ancient Greece to the present day. Laying bare the audacious research that has led us to mind-bending solutions, Davies reveals how we might begin to approach the greatest outstanding enigmas of all.

U.S.A.F. Chief of Staff 2013 Professional Reading List Selection Nearly forty years passed between the Apollo moon landings, the grandest accomplishment of a government-run space program, and the Ansari X PRIZE-winning flights of SpaceShipOne, the greatest achievement of a private space program. Now, as we hover on the threshold of commercial spaceflight, authors Chris Dubbs and Emeline Paat-Dahlstrom look back at how we got to this point. Their book traces the lives of the individuals who shared the dream that private individuals and private enterprise belong in space. Realizing Tomorrow provides a behind-the-scenes look at the visionaries, the crackpots, the financial schemes, the legal wrangling, the turf battles, and-underpinning the entire drama-the overwhelming desire of ordinary people to visit outer space. A compelling story of the pioneers of commercial spaceflight-and their efforts to open the final frontier to everyone-this book traces the path to private spaceflight even as it offers an instructive, entertaining, and cautionary note about its future.

"Let's go!" With that, the boyish, grinning Yuri Gagarin launched into space on April 12, 1961, becoming the first human being to exit Earth's orbit. The twenty-seven-year-old lieutenant colonel departed for the stars from within the shadowy world of the Soviet military-industrial complex. Barbed wires, no-entry placards, armed guards, false identities, mendacious maps, and a myriad of secret signs had hidden Gagarin from prying outsiders-not even his friends or family knew what he had been up to. Coming less than four years after the Russians launched Sputnik into orbit, Gagarin's voyage was cause for another round of capitalist shock and Soviet rejoicing. The Cosmonaut Who Couldn't Stop Smiling relates this twentieth-century icon's remarkable life while exploring the fascinating world of Soviet culture. Gagarin's flight brought him massive international fame-in the early 1960s, he was possibly the most photographed person in the world, flashing his trademark smile while rubbing elbows with the varied likes of Nehru, Castro, Queen Elizabeth II, and Italian sex symbol Gina Lollobrigida. Outside of the spotlight, Andrew L. Jenks reveals, his tragic and mysterious death in a jet crash became fodder for morality tales and conspiracy theories in his home country, and, long after his demise, his life continues to provide grist for the Russian popular-culture mill. This is the story of a legend, both the official one and the one of myth, which reflected the fantasies, perversions, hopes and dreams of Gagarin's fellow Russians. With this rich, lively chronicle of Gagarin's life and times, Jenks recreates the elaborately secretive world of space-age Russia while providing insights into Soviet history that will captivate a range of readers.

The Space Shuttle was once the cornerstone of the U.S. space program. However, each new flight brings us one step closer to the retirement of the shuttle in 2010. Final Countdown is the riveting history of NASA's Space Shuttle program, its missions, and its impending demise. It also examines the plans and early development of the space agency's next major effort: the Orion Crew Exploration Capsule. Journalist Pat Duggins, National Public Radio's resident space expert, chronicles the planning stages of the shuttle program in the early 1970s, the thrills of the first flight in 1981, construction of the International Space Station in the 1990s, and the decision in the early 2000s to shut it down. As a rookie reporter visiting the Kennedy Space Center hangar to view the Challenger wreckage, Duggins was in a unique position to offer a poignant eyewitness account of NASA's first shuttle disaster. In Final Countdown, he recounts the agency's struggle to rebound after the Challenger and Columbia tragedies, and explores how politics, scientific entrepreneurship, and the human drive for exploration have impacted the program in sometimes unexpected ways. Duggins has covered eighty-six shuttle missions, and his twenty-year working relationship with NASA has given him unprecedented access to personnel. Many spoke openly and frankly with him, including veteran astronaut John Young, who discusses the travails to get the shuttle program off the ground. Young's crewmate, astronaut Bob Crippen, reveals the frustration and loss he felt when his first opportunity to go into space on the first planned space station was taken away. As the shuttle program winds down, more astronauts may facesimilar disappointments. Final Countdown is a story of lost dreams, new hopes, and the ongoing conquest of space.

In this one-of-a-kind memoir, Jack Clemons?a former lead engineer in support of NASA?takes readers behind the scenes and into the inner workings of the Apollo and Space Shuttle programs during their most exciting years. Discover the people, the events, and the risks involved in one of the most important parts of space missions: bringing the astronauts back home to Earth. Clemons joined Project Apollo in 1968, a young engineer inspired by science fiction and electrified by John F. Kennedy's challenge to the nation to put a man on the moon. He describes his experiences supporting the NASA engineering team at what is now the Johnson Space Center in Houston, where he played a pivotal role in designing the reentry and landing procedures for Apollo astronauts. He went on to work on Skylab and the Space Shuttle program, eventually assuming leadership for the entire integrated software system on board the Space Shuttle. Through personal stories, Clemons introduces readers to many of the unsung heroes of the Apollo and Space Shuttle missions?the people who worked side-by-side with NASA engineers supporting reentry and landing for each Apollo mission, and the software team who fashioned the computer programs that accompanied the crews on the Space Shuttle. Clemons worked closely with astronauts who relied on him and his fellow engineers for directions to their destination, guidance on how to get there, control of their fate during their journeys, and a safe return. He reveals problems, challenges, and near-disasters previously unknown to the public and offers candid opinions on the failures that led to the loss of 14 astronauts in the Challenger and Columbia tragedies. Highlighting the staggering responsibility and the incredible technological challenges that Clemons and his colleagues took on in the race to reach the moon and explore the mysteries of space, this book is a fascinating insider's view of some of the greatest adventures of the twentieth century.
