Book Description
This scholarly study of NASA's Marshall Space Flight Center places the institution in social, political, scientific, and technological context. It traces the evolution of Marshall, located in Huntsville, Alabama, from its origins as an Army missile development organization to its status in 1990 as one of the most diversified of NASA's field Centers. Chapters discuss military rocketry programs in Germany and the United States, Apollo-Saturn, Skylab, Space Shuttle, Spacelab, the Space Station and various scientific and technical projects including the Hubble Space Telescope. It sheds light not only on the history of space technology, science, and exploration, but also on the Cold War, federal politics, and complex organizations.

Book Description
Spacecraft require electrical energy. This energy must be available in the outer reaches of the solar system where sunlight is very faint. It must be available through lunar nights that last for 14 days, through long periods of dark and cold at the higher latitudes on Mars, and in high-radiation fields such as those around Jupiter. Radioisotope power systems (RPSs) are the only available power source that can operate unconstrained in these environments for the long periods of time needed to accomplish many missions, and plutonium-238 (238Pu) is the only practical isotope for fueling them. Plutonium-238 does not occur in nature. The committee does not believe that there is any additional 238Pu (or any operational 238Pu production facilities) available anywhere in the world.The total amount of 238Pu available for NASA is fixed, and essentially all of it is already dedicated to support several pending missions-the Mars Science Laboratory, Discovery 12, the Outer Planets Flagship 1 (OPF 1), and (perhaps) a small number of additional missions with a very small demand for 238Pu. If the status quo persists, the United States will not be able to provide RPSs for any subsequent missions.

Book Description
This book offers a fresh and advanced perspective on the three important angles (houses) of the chart (kundali) traditionally known as TRIKONA, which are, the ascendant, the fifth and the ninth houses. It tells us how these houses influence one's life constantly and how the planets, when own these houses, influence individual's life. 36 case studies have been discussed in detail to show how planets play their role in the growth of human beings.

Book Description
In September 2017, Hurricane Maria hit Puerto Rico, completely upending the energy grid of the small island. The nearly year-long power outage that followed vividly shows how the new climate reality intersects with race and access to energy. The island is home to brown and black US citizens who lack the political power of those living in the continental US. As the world continues to warm and storms like Maria become more commonplace, it is critical that we rethink our current energy system to enable reliable, locally produced, and locally controlled energy without replicating the current structures of power and control. In Revolutionary Power, Shalanda Baker arms those made most vulnerable by our current energy system with the tools they need to remake the system in the service of their humanity. She argues that people of color, poor people, and indigenous people must engage in the creation of the new energy system in order to upend the unequal power dynamics of the current system. Revolutionary Power is a playbook for the energy transformation complete with a step-by-step analysis of the key energy policy areas that are ripe for intervention. Baker tells the stories of those who have been left behind in our current system and those who are working to be architects of a more just system. She draws from her experience as an energy-justice advocate, a lawyer, and a queer woman of color to inspire activists working to build our new energy system. Climate change will force us to rethink the way we generate and distribute energy and regulate the system. But how much are we willing to change the system? This unique moment in history provides an unprecedented opening for a deeper transformation of the energy system, and thus, an opportunity to transform society. Revolutionary Power shows us how.

Book Description
A global tour of energy--the builder of human civilization and also its greatest threat. Energy is humanity's single most important resource. In fact, as energy expert Michael E. Webber argues in Power Trip, the story of how societies rise can be told largely as the story of how they manage energy sources through time. In 2019, as we face down growing demand for and accumulating environmental impacts from energy, we are at a crossroads and the stakes are high. But history shows us that energy's great value is that it allows societies to reinvent themselves. Power Trip explores how energy has transformed societies of the past and offers wisdom for today's looming energy crisis. There is no magic bullet; energy advances always come with costs. Scientific innovation needs public support. Energy initiatives need to be tailored to individual societies. We must look for long-term solutions. Our current energy crisis is real, but it is solvable. We have the power.

Book Description
In a 2014 essay that went viral, Pippa Biddle revealed the inequities and absurdities baked into voluntourism--the pairing of short-term, unskilled volunteer work with tourism. In the years since, Biddle has devoted herself to understanding the origins, intentions, and outcomes of a multibillion-dollar industry built on the premise of doing good, and she tracks that investigation in Ours to Explore. The flaws of voluntourism have included xenophobia, racism, paternalism, and a "West knows best" mentality. From exploitative orphanages that keep children in squalid conditions to attract donors to undertrained medical volunteers practicing their skills on patients in developing regions and to those looking for an inspiring selfie, Biddle reveals the hidden costs of the voluntourism complex. Along the way, readers meet inspiring activists and passionate community members, as well as thoughtful former voluntourists who still work to make a difference--just differently. Ours to Explore offers a plan for how the service-based travel industry can break the cycle of exploitation and suggests strategies for travelers who want to improve the places they visit for the long haul.

Book Description
This book investigates whether a power shift has taken place in the Asia-Pacific region since the end of the Cold War. By systematically examining the development of power dynamics in Asia-Pacific, it challenges the notion that a wealthier and militarily more powerful China is automatically turning the regional tides in its favour. With a special emphasis on Sino-US competition, the book explores the alleged linkage between the regional distribution of relevant material and immaterial capabilities, national power and the much-cited regional power shift. The book presents a novel concept for measuring power in international relations by outlining a composite index on aggregated power (CIAP) that includes 55 variables for 44 regional countries and covers a period of twenty years. Moreover, it develops a middle power theory that outlines the significance of middle powers in times of major power shifts. By addressing political, military and economic cooperation via a structured-focused comparison and by applying a comparative-historical analysis, the book analyses in depth the bilateral relations of six regional middle powers to Washington and Beijing.
