NASA's Science Mission Directorate (SMD) currently operates over five dozen missions, with approximately two dozen additional missions in development. These missions span the scientific fields associated with SMD's four divisionsâ€"Astrophysics, Earth Science, Heliophysics, and Planetary Sciences. Because a single mission can consist of multiple spacecraft, NASA-SMD is responsible for nearly 100 operational spacecraft. The most high profile of these are the large strategic missions, often referred to as "flagships." Large strategic missions are essential to maintaining the global leadership of the United States in space exploration and in science because only the United States has the budget, technology, and trained personnel in multiple scientific fields to conduct missions that attract a range of international partners. This report examines the role of large, strategic missions within a balanced program across NASA-SMD space and Earth sciences programs. It considers the role and scientific productivity of such missions in advancing science, technology and the long-term health of the field, and provides guidance that NASA can use to help set the priority of larger missions within a properly balanced program containing a range of mission classes.

The original charter of the Space Science Board was established in June 1958, three months before the National Aeronautics and Space Administration (NASA) opened its doors. The Space Science Board and its successor, the Space Studies Board (SSB), have provided expert external and independent scientific and programmatic advice to NASA on a continuous basis from NASA's inception until the present. The SSB has also provided such advice to other executive branch agencies, including the National Oceanic and Atmospheric Administration (NOAA), the National Science Foundation (NSF), the U.S. Geological Survey (USGS), the Department of Defense, as well as to Congress. Space Studies Board Annual Report 2017 covers a message from the chair of the SSB, David N. Spergel. This report also explains the origins of the Space Science Board, how the Space Studies Board functions today, the SSB's collaboration with other National Academies of Sciences, Engineering, and Medicine units, assures the quality of the SSB reports, acknowledges the audience and sponsors, and expresses the necessity to enhance the outreach and improve dissemination of SSB reports. This report will be relevant to a full range of government audiences in civilian space research - including NASA, NSF, NOAA, USGS, and the Department of Energy, as well members of the SSB, policy makers, and researchers.

From exoskeletons to neural implants, biomedical devices are no less than life-changing. Compact and constant power sources are necessary to keep these devices running efficiently. Edwar Romero's Powering Biomedical Devices reviews the background, current technologies, and possible future developments of these power sources, examining not only the types of biomedical power sources available (macro, mini, MEMS, and nano), but also what they power (such as prostheses, insulin pumps, and muscular and neural stimulators), and how they work (covering batteries, biofluids, kinetic and thermal energy, and telemetry). The book also looks at challenges such as energy generation efficiency, energy density, rectification, and energy storage and management. A final section on future trends rounds out the book. By briefly examining these key aspects, this book gives its readers a valuable overview of biomedical devices' power sources. A compact introduction to the vital topic of biomedical devices' power sources Reviews the background, current technologies, and possible future developments of biomedical power sources Short-format text allows for material that is clear, concise, and to-the-point Extensive references provided for further reading

Inductive powering has been a reliable and simple method for many years to wirelessly power devices over relatively short distances, from a few centimetres to a few feet. Examples are found in biomedical applications, such as cochlear implants; in RFID, such as smart cards for building access control; and in consumer devices, such as electrical toothbrushes. Device sizes shrunk considerably the past decades, demanding accurate design tools to obtain reliable link operation in demanding environments. With smaller coil sizes, the link efficiency drops dramatically to a point where the commonly used calculation methods become invalid. Inductive Powering: Basic Theory and Application to Biomedical Systems lists all design equations and topology alternatives to successfully build an inductive power and data link for your specific application. It also contains practical guidelines to expand the external driver with a servomechanism that automatically tunes itself to varying coupling and load conditions.

With nearly all of the world's energy consumption dependent on non-renewable resources, Powering Our Future challenges consumers to support changes that will create sustainable energy in the future. The four biggest energy sources--oil, natural gas, coal, and uranium--currently power our earth. What would happen to our society if we experienced severe shortages of one or more of these resources? Such a glimpse into the future may become reality sooner than we think. Oil production is soon expected to begin a rapid descent, with natural gas in close pursuit. Powering Our Future is an educational tool that opens the door to a future fueled by sustainable, renewable energy. Consumers will learn: - How our world has become dependent on four nonrenewable resources. - How each resource impacts us politically, economically, and environmentally. - How renewable resources such as hydrogen, fuel cells, wind power, solar energy, hydropower, and more are waiting in the wings. - How the transition to renewable resources will take place, offering economically stable and environmentally safe choices. Powering Our Future is a solution-oriented guide that will empower you to make more informed choices as a voter, a contributor to a global economy, and a citizen of the earth.

At the request of the Deputy Assistant Secretary of the Army for Research and Technology, Powering the U.S. Army of the Future examines the U.S. Army's future power requirements for sustaining a multi-domain operational conflict and considers to what extent emerging power generation and transmission technologies can achieve the Army's operational power requirements in 2035. The study was based on one operational usage case identified by the Army as part of its ongoing efforts in multi-domain operations. The recommendations contained in this report are meant to help inform the Army's investment priorities in technologies to help ensure that the power requirements of the Army's future capability needs are achieved.

Philosophy and Science are subject to conflicting interpretations, such as the rules of positivism and analytic thought. Bernard Lonergan and Gilles Deleuze have both assessed such issues in complementary fashion. This book examines their arguments through the application of mathematical theories and Buddhist-Christian ethics in an attempt to bridge the religious-secularist divide exacerbated by postmodernism.
