Book Description
This study assumes Space Elevators can and must be built. "Space Elevators: The Green Road to Space," completed in April 2021, emphasizes that Space Elevators will not replace rockets but would join them on parallel paths towards the stars. This Dual Space Access Strategy will carry out the missions that are now planned and ensure the future we dream of becomes a reality. Space Elevators are needed to do the "heavy lifting" for movement off planet. Their transformational characteristics will enable so many of humanity's dreams by moving huge mass to far away destinations. Space Elevator Vision: Space Elevators are the Green Road to Space while they enable humanity's most important missions by moving massive tonnage to GEO and beyond. They accomplish this safely, routinely, inexpensively, efficiently, daily and they are environmentally neutral.

Book Description
This 18-month study has produced some remarkable results during a time of transition inside the space arena. As the dreams of many describe customer needs and lead to more assets in space (at GEO, the Moon and Mars), the realization grows that a robust permanent transportation infrastructure is desperately needed. Essentially, we (ISEC) must insert the "positive environmental impact" aspect of spaceflight into a new vision. Everyone needs to understand the potential benefits of liftoffs accomplished by electricity. Our new vision is: Space Elevators are the Green Road to Space - they enable humanity's most important missions by moving massive tonnage to GEO and beyond. They accomplish this safely, routinely, inexpensively, daily and they are environmentally neutral. This study shows how the Space Elevator can actually enhance the Earth's environment and accomplishes much to fulfill the dreams of many. The compatible and complementary combination of future rockets and Space Elevators leads to the implementation of the Dual Space Access Architecture which enables: Rockets to open up the Moon and Mars with Space Elevators to supply and grow the colonies. In addition, Space Elevators will enable Green Missions such as, Space Solar Power and L-1 Sun Shades.

Book Description
What is a space elevator? A space elevator is a physical connection from the surface of the Earth to a geostationary Earth orbit (GEO) above the Earth .35,786 km in altitude. Its center of mass is at the geostationary point such that it has a 24-hr orbit and stays over the same point above the equator as the Earth rotates on its axis. The vision is that a space elevator would be utilized as a transportation and utility system for moving people, payloads, power, and gases between the surface of the Earth and space. It makes the physical connection from Earth to space in the same way a bridge connects two cities across a body of water. The Earth to GEO space elevator is not feasible today, but could be an important concept for the future development of space in the latter part of the 21st century. It has the potential to provide mass transportation to space in the same way highways, railroads, power lines, and pipelines provide mass transportation across the Earth's surface. The low energy requirements for moving payloads up and down the elevator could make it possible to achieve cost to orbit

Book Description
Michel van Pelt explains for the first time the principle of space tethers: what they are and how they can be used in space. He introduces non-technical space enthusiasts to the various possibilities and feasibility of space tethers including the technological challenges and potential benefits. He illustrates how, because of their inherent simplicity, space tethers have the potential to make space travel much cheaper, while ongoing advances in tether material technology may make even seemingly far-fetched ideas a reality in the not too distant future.

Book Description
The authors take the reader through the history of the concept, technical design and economic practicalities of building an elevator to space, and, ultimately, the implications of what such a low cost transportation system would mean to society. Based on three years of NASA-funded studies and written for the technically literate layperson, Edwards and Westling discuss the recent technological advances that now make the space elevator feasible. They conclude by addressing the effects that the space elevator could have on mankind's future from communications and energy to colonizing space.

Book Description
The National Aerospace Initiative (NAI) was conceived as a joint effort between the Department of Defense (DOD) and the National Aeronautics and Space Administration (NASA) to sustain the aerospace leadership of the United States through the acceleration of selected aerospace technologies: hypersonic flight, access to space, and space technologies. The Air Force became concerned about the NAI's possible consequences on Air Force programs and budget if NAI program decisions differed from Air Force priorities. To examine this issue, it asked the NRC for an independent review of the NAI. This report presents the results of that assessment. It focuses on three questions asked by the Air Force: is NAI technically feasible in the time frame laid out; is it financially feasible over that period; and is it operationally relevant.

Book Description
From the authors' abstract: "This analytical study looks at the importance of Deep Space Operations and recommends an approach for senior policy leaders. Section 1 presents a capability requirements definition with candidate solutions and technology strategies. Section 2 recommends an acquisition and organizational approach. Section 3 provides an extended strategic rationale for deep space operations as a national priority." And from the Introduction: [this essay] "presents capability requirements, potential solutions, and strategic rationale for achieving movement and maneuver advantage in deep space. In this context, deep space is anything beyond geosynchronous Earth orbit (GEO). Driving the research are two primary assumptions underpinning the need for investment in deep space propulsion. The first assumption is that growing international activity, commerce, and industry in space extends the global commons, thus creating a military-economic imperative for the United States Department of Defense (DoD) to expand its protection of U.S. interests by defending space lines of communication. Although there are wide-ranging reasons to expand the space-faring capabilities of the human species, from the capitalistic to the existential, the fact of its occurrence offers the U.S. immense strategic opportunity. Section 1, operating on this assumption, recommends capability-based requirements for deep space operations given a projected future operating environment.The second driving assumption underpinning this study is that improved movement and maneuver capabilities in deep space offer a wide array of benefits for the current National Security Enterprise, and for this reason alone demands attention in the form of disciplined investment. Furthermore, because the core functional capability required for deep space operations is in-space propulsion, the requirement necessitates a materiel solution.

Book Description
In the last year, the International Space Elevator Consortium assessed that basic technological needs can be met with current capabilities: and, each segment of the Space Elevator Transportation System is ready for engineering validation. Because of the availability of a new material as a potential Space Elevator tether, the community strongly believes that a Space Elevator will be initiated in the near term. Included in the book is a series of appendices that are tremendous references to the status of the space elevator today. Included are a lexicon of space elevator terms, over 750 references in the bibliography, short descriptions of eight ISEC year-long studies and two IAA 4-year studies on space elevators, as well as a summary of over 20 Architectural Notes covering the development of space elevator technologies.

Book Description
Rocket and air-breathing propulsion systems are the foundation on which planning for future aerospace systems rests. A Review of United States Air Force and Department of Defense Aerospace Propulsion Needs assesses the existing technical base in these areas and examines the future Air Force capabilities the base will be expected to support. This report also defines gaps and recommends where future warfighter capabilities not yet fully defined could be met by current science and technology development plans.
