Book Description
Primary source of electric power for the International Space Station (ISS) is the photovoltaic module (PVM). At assembly complete stage, the ISS will be served by 4 PVMs. Each PVM contains two independent power channels such that one failure will result in loss of only one power channel. During early stages of assembly, the ISS is served by only one PVM designated as P6. Solar arrays are used to convert solar flux into electrical power. Nickel hydrogen batteries are used to store electrical power for use during periods when the solar input is not adequate to support channel loads. Batteries are operated per established procedures that ensure that they are maintained within specified temperature limits, charge current is controlled to conform to a specified charge profile, and battery voltages are maintained within specified limits. Both power channels on the PVM P6 have been operating flawlessly since December 2000 with 100 percent power availability. All components, including batteries, are monitored regularly to ensure that they are operating within specified limits and to trend their wear out and age effects. The paper briefly describes the battery trend data. Batteries have started to show some effects of aging and a battery reconditioning procedure is being evaluated at this time. Reconditioning is expected to reduce cell voltage divergence and provide data that can be used to update the state of charge (SOC) computation in the software to account for battery age. During reconditioning, each battery, one at a time, will be discharged per a specified procedure and then returned to a full state of charge. The paper describes the reconditioning procedure and the expected benefits. The reconditioning procedures have been thoroughly coordinated by all affected technical teams and approved by all required boards. The reconditioning is tentatively scheduled for September 2004.

Book Description
Looks at the operations of the International Space Station from the perspective of the Houston flight control team, under the leadership of NASA's flight directors, who authored the book. The book provides insight into the vast amount of time and energy that these teams devote to the development, planning and integration of a mission before it is executed. The passion and attention to detail of the flight control team members, who are always ready to step up when things do not go well, is a hallmark of NASA human spaceflight operations. With tremendous support from the ISS program office and engineering community, the flight control team has made the International Space Station and the programs before it a success.

Book Description
System Health Management: with Aerospace Applications provides the first complete reference text for System Health Management (SHM), the set of technologies and processes used to improve system dependability. Edited by a team of engineers and consultants with SHM design, development, and research experience from NASA, industry, and academia, each heading up sections in their own areas of expertise and co-coordinating contributions from leading experts, the book collates together in one text the state-of-the-art in SHM research, technology, and applications. It has been written primarily as a reference text for practitioners, for those in related disciplines, and for graduate students in aerospace or systems engineering. There are many technologies involved in SHM and no single person can be an expert in all aspects of the discipline.System Health Management: with Aerospace Applications provides an introduction to the major technologies, issues, and references in these disparate but related SHM areas. Since SHM has evolved most rapidly in aerospace, the various applications described in this book are taken primarily from the aerospace industry. However, the theories, techniques, and technologies discussed are applicable to many engineering disciplines and application areas. Readers will find sections on the basic theories and concepts of SHM, how it is applied in the system life cycle (architecture, design, verification and validation, etc.), the most important methods used (reliability, quality assurance, diagnostics, prognostics, etc.), and how SHM is applied in operations (commercial aircraft, launch operations, logistics, etc.), to subsystems (electrical power, structures, flight controls, etc.) and to system applications (robotic spacecraft, tactical missiles, rotorcraft, etc.).

Book Description
The power systems of space vehicles have undergone significant development during the previous decade, and will continue to do so in the immediate future. Until now, except for the scattered results of conferences and a few publications with sketchy coverage, no single volume has covered the entire spectrum of the subject. Spacecraft Power

Book Description
As the most obvious man-made object in the night sky, clearly visible to the naked eye, the International Space Station is of interest to almost everyone. Richly illustrated with around 100 figures this is the first book to describe the technical aspects of its design and construction and details of its day-to-day operation. The text relates the orbital assembly on a flight-by-flight basis, listing all the experiments in NASA's laboratory and explains their objectives. By offering a comprehensive mix of operational work, microgravity, science and future plans, it will satisfy both the space enthusiast, eager for a detailed review of the missions, and the specialist wishing to learn more about this science programme.

Book Description
Spacecraft Lithium-Ion Battery Power Systems Helps Readers Better Understand the Design, Development, Test, and Safety Engineering of Spacecraft Lithium-Ion Battery Power Systems Written by highly experienced spacecraft engineers and scientists working at the heart of the industry, Spacecraft Lithium-Ion Battery Power Systems is one of the first books to provide a comprehensive treatment of the broad area of spacecraft battery power systems technology. The work emphasizes the technical aspects across the entire lifecycle of spacecraft batteries including the requirements, design, manufacturing, testing, and safety engineering principles needed to field a reliable spacecraft electrical power system. A special focus on rechargeable lithium-ion battery technologies as they apply to manned and unmanned Earth-orbiting satellites, Cubesats, planetary mission spacecraft (such as orbiters, landers, rovers, and probes), and launch vehicle applications is emphasized. Using a systems engineering approach, the book smoothly bridges knowledge gaps that typically exist between academic and industry practitioners. Sample topics of discussion and learning resources included in the work include: Detailed systematic technical treatment of spacecraft LIB power systems across the entire lithium-ion battery life cycle Principles of lithium-ion cell and battery design, battery management systems, electrical power systems, safety engineering, life cycle testing, ground processing, and on-orbit mission operations Special topics such as requirements engineering, qualification testing, safety hazards and controls, reliability analysis, life modeling and prediction, on-orbit battery power system management, and decommissioning strategies New and emerging on-orbit space applications of LIBs supporting commercial, civil, and government spacecraft missions (International Space Station, Galileo, James Webb Telescope, Mars 2020 Perseverance Rover, Europa Clipper) Real space industry case studies of deployed Earth-orbiting satellite, astronaut, and planetary mission spacecraft lithium-ion batteries Overall, the work provides professionals supporting the commercial, civil, and government aerospace marketplace with key knowledge and highly actionable information pertaining to lithium-ion batteries and their specific applications in modern spacecraft systems.
