This reference work gathers all of the latest technologies, information, definitions and explanations of spacecraft life support systems, while providing in-depth coverage of the current knowledge of the business of keeping astronauts alive during their missions. It is intended that this MRW be the go-to reference work not only for aerospace engineers, but also for graduate and undergraduate aerospace engineers and space scientists. The area of spacecraft life support is comprised of dozens of specialties and sub-specialties within the fields of engineering, biophysics, and medicine. As space agencies around the world pursue cutting-edge life support technologies, much more information and data is accumulated. When humans move out into the solar system to stay for long durations, the most immediate challenge will be the provision of reliable and robust life support systems in locations devoid of food, air, and water. These life support systems must provide these commodities in each phase of spaceflight, including intra-vehicular activity (IVA) and extra-vehicular activity (EVA). Systems supporting human life must also fulfill myriad requirements: exceptional reliability in the space environment, allowing maintenance and component replacement in space; reduced resupply mass of consumables and spares; the ability to utilize local planetary resources for self sufficiency; and minimized mass power and volume requirements. These requirements will assume ever greater importance as bolder missions are envisioned and more sophisticated life support systems are required. For example, the next decade could see human missions to Mars and a return to the Moon. In the not-so-distant future, there is the prospect of Mars One and the creation of a permanent extraterrestrial colony. It may appear that a suitable environment can be created simply by reproducing terrestrial environmental conditions within a vehicle. In reality, it is first necessary to define the environmental characteristics humans require and match these requirements with the myriad design constraints. This is no easy task, because implementing these environmental parameters within a spacecraft can be challenging, while balancing the various requirements and constraints can test the abilities of even the most gifted aerospace engineer. Yet it is a crucial field of study and the experts contributing to this volume are on the very front lines.

More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.

To meet the objectives of the Vision for Space Exploration (VSE), NASA must develop a wide array of enabling technologies. For this purpose, NASA established the Exploration Technology Development Program (ETDP). Currently, ETDP has 22 projects underway. In the report accompanying the House-passed version of the FY2007 appropriations bill, the agency was directed to request from the NRC an independent assessment of the ETDP. This interim report provides an assessment of each of the 22 projects including a quality rating, an analysis of how effectively the research is being carried out, and the degree to which the research is aligned with the VSE. To the extent possible, the identification and discussion of various cross-cutting issues are also presented. Those issues will be explored and discussed in more detail in the final report.

In January 2004, President George W. Bush announced the Vision for Space Exploration (VSE), which instructed NASA to "Extend human presence across the solar system, starting with a human return to the Moon by the year 2020, in preparation for human exploration of Mars and other destinations," among other objectives. As acknowledged in the VSE, significant technology development will be necessary to accomplish the goals it articulates. NASA's Exploration Technology Development Program (ETDP) is designed to support, develop, and ultimately provide the necessary technologies to meet the goals of the VSE. This book, a review of the ETDP, is broadly supportive of the intent and goals of the VSE, and finds the ETDP is making progress towards the stated goals of technology development. However, the ETDP is operating within significant constraints which limit its ability to successfully accomplish those goals-the still dynamic nature of the Constellation Program requirements, the constraints imposed by a limited budget, the aggressive time scale of early technology deliverables, and the desire to fully employ the NASA workforce.

For a given fixed launch vehicle capacity the logistics payload delivered to the moon may be only roughly 20 percent of the payload delivered to the International Space Station (ISS). This is compounded by the much lower flight frequency to the moon and thus low availability of spares for maintenance. This implies that lunar hardware is much more scarce and more costly per kilogram than ISS and thus there is much more incentive to preserve hardware. The Constellation Lunar Surface System (LSS) program is considering ways of utilizing hardware scavenged from vehicles including the Altair lunar lander. In general, the hardware will have only had a matter of hours of operation yet there may be years of operational life remaining. By scavenging this hardware the program, in effect, is treating vehicle hardware as part of the payload. Flight hardware may provide logistics spares for system maintenance and reduce the overall logistics footprint. This hardware has a wide array of potential applications including expanding the power infrastructure, and exploiting in-situ resources. Scavenging can also be seen as a way of recovering the value of, literally, billions of dollars worth of hardware that would normally be discarded. Scavenging flight hardware adds operational complexity and steps must be taken to augment the crew s capability with robotics, capabilities embedded in flight hardware itself, and external processes. New embedded technologies are needed to make hardware more serviceable and scavengable. Process technologies are needed to extract hardware, evaluate hardware, reconfigure or repair hardware, and reintegrate it into new applications. This paper also illustrates how scavenging can be used to drive down the cost of the overall program by exploiting the intrinsic value of otherwise discarded flight hardware. Oeftering, Richard C.

Today's astronauts require many different abilities. They must not only be expert in performing flight simulations but must also be proficient in such dissimilar subjects as photography, thermodynamics, electrical repairs, flight procedures, oceanography, public affairs, and geology. In Prepare for Launch, the author introduces the technologies and myriad activities that constitute or affect astronaut training, such as the part-task trainers, emergency procedures, the fixed-based and motion-based simulators, virtual environment training, and the demands of training in the Weightless Environment Training Facility. With plans to return to the Moon and future missions to Mars, the current selection criteria and training are very different from those used for short duration mission Space Shuttle crews. Dr. Erik Seedhouse in this book focuses on how astronaut candidates are taught to cope with different needs and environments (for example, hibernation, artificial gravity, and bioethics issues) and also includes brief discussions of the astronaut application and selection process.

While the Moon was once thought to hold the key to space exploration, in recent decades, the U.S. has largely turned its sights toward Mars and other celestial bodies instead. In The Value of the Moon, lunar scientist Paul Spudis argues that the U.S. can and should return to the moon in order to remain a world leader in space utilization and development and a participant in and beneficiary of a new lunar economy. Spudis explores three reasons for returning to the Moon: it is close, it is interesting, and it is useful. The proximity of the Moon not only allows for frequent launches, but also control of any machinery we place there. It is interesting because recorded deep on its surface and in its craters is the preserved history of the moon, the sun, and indeed the entire galaxy. And finally, the moon is useful because it is rich with materials and energy. The moon, Spudis argues, is a logical base for further space exploration and even a possible future home for us all. Throughout his work, Spudis incorporates details about man's fascination with the moon and its place in our shared history. He also explores its religious, cultural, and scientific resonance and assesses its role in the future of spaceflight and our national security and prosperity.
