Book Description
As the National Aeronautics and Space Administration (NASA) retires the Space Shuttle and shifts involvement in International Space Station (ISS) operations, changes in the role and requirements of NASA's Astronaut Corps will take place. At the request of NASA, the National Research Council (NRC) addressed three main questions about these changes: what should be the role and size of Johnson Space Center's (JSC) Flight Crew Operations Directorate (FCOD); what will be the requirements of astronaut training facilities; and is the Astronaut Corps' fleet of training aircraft a cost-effective means of preparing astronauts for NASA's spaceflight program? This report presents an assessment of several issues driven by these questions. This report does not address explicitly the future of human spaceflight.

Book Description
In February 2009, the commercial communications satellite Iridium 33 collided with the Russian military communications satellite Cosmos 2251. The collision, which was not the first recorded between two satellites in orbit-but the most recent and alarming-produced thousands of pieces of debris, only a small percentage of which could be tracked by sensors located around the world. In early 2007, China tested a kinetic anti-satellite weapon against one of its own satellites, which also generated substantial amounts of space debris. These collisions highlighted the importance of maintaining accurate knowledge, and the associated uncertainty, of the orbit of each object in space. These data are needed to predict close approaches of space objects and to compute the probability of collision so that owners/operators can decide whether or not to make a collision avoidance maneuver by a spacecraft with such capability. The space object catalog currently contains more than 20,000 objects, and when the planned space fence radar becomes operational this number is expected to exceed 100,000. A key task is to determine if objects might come closer to each other, an event known as "conjunction," and the probability that they might collide. The U.S. Air Force is the primary U.S. government organization tasked with maintaining the space object catalog and data on all space objects. This is a complicated task, involving collecting data from a multitude of different sensors-many of which were not specifically designed to track orbiting objects-and fusing the tracking data along with other data, such as data from atmospheric models, to provide predictions of where objects will be in the future. The Committee for the Assessment of the U.S. Air Force's Astrodynamic Standards collected data and heard from numerous people involved in developing and maintaining the current astrodynamics standards for the Air Force Space Command (AFSPC), as well as representatives of the user community, such as NASA and commercial satellite owners and operators. Preventing collisions of space objects, regardless of their ownership, is in the national security interested of the United States. Continuing Kepler's Quest makes recommendations to the AFSPC in order for it to create and expand research programs, design and develop hardware and software, as well as determine which organizations to work with to achieve its goals.

Book Description
"Robert Zubrin is a true engineering genius like the heroic engineers of the past." --Frederick Turner, American Enterprise Using nuts-and-bolts engineering and a unique grasp of human history, Robert Zubrin takes us to the not-very-distant future, when our global society will branch out into the universe. From the current-day prospect of lunar bases and Mars settlements to the outer reaches of other galaxies, Zubrin delivers the most important and forward-looking work on space and the true possibilities of human exploration since Carl Sagan's Cosmos. Sagan himself said of Zubrin's humans-to-Mars plan, "Bob Zubrin really, nearly alone, changed our thinking on this issue." With Entering Space, he takes us further, into the prospect of human expansion to the outer planets of our own solar system--and beyond.

Book Description
Enhancing awareness of the interdependence of systems engineering and safety, Systems Engineering and Safety: Building the Bridge covers systems engineering methodology, safety tools, and the management needed to build the bridge between these two disciplines. It underscores the relationship between the disciplines and how understanding the relationship can benefit your organization and industry. The book lays out the purpose of the methodology of systems engineering and the tools of safety. It identifies the importance of management and the culture, commitment, communication, and coordination that management must provide. The author describes the systems engineering methodology: the lifecycle, processes, and management and the technical processes that systems engineers and safety professionals must be familiar with. He merges management, systems engineering, and safety into the lifecycle through project processes. Using real-world examples, he also examines the roles and responsibilities of management, and a breakdown theory of safety in the management processes: The Glismann Effect. The strength of this book is that it can be read, understood, and hopefully acted upon by the chief executive officer of a corporation, right down to the line manager of systems engineering or the subject matter expert in the safety department. This value can be measured in cost savings, be it in the form of human, social, or financial capital.

Book Description
On June 15, 2011, the Air Force Space Command established a new vision, mission, and set of goals to ensure continued U.S. dominance in space and cyberspace mission areas. Subsequently, and in coordination with the Air Force Research Laboratory, the Space and Missile Systems Center, and the 14th and 24th Air Forces, the Air Force Space Command identified four long-term science and technology (S&T) challenges critical to meeting these goals. One of these challenges is to provide full-spectrum launch capability at dramatically lower cost, and a reusable booster system (RBS) has been proposed as an approach to meet this challenge. The Air Force Space Command asked the Aeronautics and Space Engineering Board of the National Research Council to conduct an independent review and assessment of the RBS concept prior to considering a continuation of RBS-related activities within the Air Force Research Laboratory portfolio and before initiating a more extensive RBS development program. The committee for the Reusable Booster System: Review and Assessment was formed in response to that request and charged with reviewing and assessing the criteria and assumptions used in the current RBS plans, the cost model methodologies used to fame [frame?] the RBS business case, and the technical maturity and development plans of key elements critical to RBS implementation. The committee consisted of experts not connected with current RBS activities who have significant expertise in launch vehicle design and operation, research and technology development and implementation, space system operations, and cost analysis. The committee solicited and received input on the Air Force launch requirements, the baseline RBS concept, cost models and assessment, and technology readiness. The committee also received input from industry associated with RBS concept, industry independent of the RBS concept, and propulsion system providers which is summarized in Reusable Booster System: Review and Assessment.

Book Description
For the National Aeronautics and Space Administration (NASA) to achieve many of its space science and exploration goals over the next several decades, dramatic advances in space technology will be necessary. NASA has developed a set of 14 draft roadmaps to guide the development of such technologies under the leadership of the NASA Office of the Chief Technologist (OCT). Each roadmap focuses on a particular technology area. OCT requested that the National Research Council conduct a study to review the draft roadmaps, gather and assess relevant community input, and make recommendations and suggest priorities to inform NASA's decisions as it finalizes its roadmaps. The success of OCT's technology development program is essential, because technological breakthroughs have long been the foundation of NASA's successes, from its earliest days, to the Apollo program, to a vast array of space science missions and the International Space Station. An Interim Report of NASA's Technology Roadmap identifies some gaps in the technologies included in the individual roadmaps. The report suggests that the effectiveness of the NASA space technology program can be enhanced by employing proven management practices and principles including increasing program stability, addressing facility issues, and supporting adequate flight tests of new technologies. This interim report provides several additional observations that will be expanded on in the final report to be released in 2012.

Book Description
Derelict satellites, equipment and other debris orbiting Earth (aka space junk) have been accumulating for many decades and could damage or even possibly destroy satellites and human spacecraft if they collide. During the past 50 years, various National Aeronautics and Space Administration (NASA) communities have contributed significantly to maturing meteoroid and orbital debris (MMOD) programs to their current state. Satellites have been redesigned to protect critical components from MMOD damage by moving critical components from exterior surfaces to deep inside a satellite's structure. Orbits are monitored and altered to minimize the risk of collision with tracked orbital debris. MMOD shielding added to the International Space Station (ISS) protects critical components and astronauts from potentially catastrophic damage that might result from smaller, untracked debris and meteoroid impacts. Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Program examines NASA's efforts to understand the meteoroid and orbital debris environment, identifies what NASA is and is not doing to mitigate the risks posed by this threat, and makes recommendations as to how they can improve their programs. While the report identified many positive aspects of NASA's MMOD programs and efforts including responsible use of resources, it recommends that the agency develop a formal strategic plan that provides the basis for prioritizing the allocation of funds and effort over various MMOD program needs. Other necessary steps include improvements in long-term modeling, better measurements, more regular updates of the debris environmental models, and other actions to better characterize the long-term evolution of the debris environment.

Book Description
The riveting story of the American scientists, tinkerers, and nerds who solved one of the biggest puzzles of World War II--and developed one of the most powerful weapons of the war.​ 12 Seconds of Silence is the remarkable, lost story of how a rag tag group of American scientists overcame one of the toughest problems of World War II: Shooting things out of the sky. Working in a secretive organization known as Section T, a team of physicists, engineers, and everyday Joes and Janes created one of the world's first "smart weapons"--the proximity fuse. The tiny gadget allowed an artillery shell to "know" when to explode to bring down an aircraft. Against overwhelming odds and in a race against time, mustering every scrap of resource, ingenuity, and insight, the scientists of Section T would eventually save countless lives, rescue the city of London from the onslaught of a Nazi superweapon, and help bring about the Axis defeat. A holy grail sought after by Allied and Axis powers alike, the fuse ranks with the atomic bomb as one of the most revolutionary technologies of the Second World War. Until now, its tale was largely untold. For fans of Erik Larson and Ben Macintyre, set amidst the fog of espionage, dueling spies, and the dawn of an age when science would determine the fate of the world, 12 Seconds of Silence is a tribute to the extraordinary wartime mobilization of American science and the ultimate can-do story.

Book Description
NASA's Office of the Chief Technologist (OCT) has begun to rebuild the advanced space technology program in the agency with plans laid out in 14 draft technology roadmaps. It has been years since NASA has had a vigorous, broad-based program in advanced space technology development and its technology base has been largely depleted. However, success in executing future NASA space missions will depend on advanced technology developments that should already be underway. Reaching out to involve the external technical community, the National Research Council (NRC) considered the 14 draft technology roadmaps prepared by OCT and ranked the top technical challenges and highest priority technologies that NASA should emphasize in the next 5 years. This report provides specific guidance and recommendations on how the effectiveness of the technology development program managed by OCT can be enhanced in the face of scarce resources.
