Available in PDF, EPUB and Kindle. Book excerpt: The definitive guide to the modern body of spacecraft charging knowledge—from first principles for the beginner to intermediate and advanced concepts The only book to blend the theoretical and practical aspects of spacecraft charging, Guide to Mitigating Spacecraft Charging Effects defines the environment that not only creates the aurora, but which also can have significant effects on spacecraft, such as disruption of science measurements and solar arrays from electrostatic discharge (ESD). It describes in detail the physics of the interaction phenomenon as well as how to construct spacecraft to enhance their survivability in the harsh environment of space. Combining the authors' extensive experience in spacecraft charging—and in their provision of design support to NASA, JPL, the commercial satellite market, and numerous other projects—this incredible book offers both a robust physics background and practical advice for neophytes in the field and experienced plasma physicists and spacecraft engineers. In addition to containing numerous equations, graphs, tables, references, and illustrations, Guide to Mitigating Spacecraft Charging Effects covers: Solar cell technology, especially higher voltage arrays, and the new design approaches that are appropriate for them Information about the space plasma environment New analytic computer codes to analyze spacecraft charging Spacecraft anomalies and failures which emphasized designs that are of greater importance than others
Book Synopsis Fundamentals of Spacecraft Charging by : Shu T. Lai
Download or read book Fundamentals of Spacecraft Charging written by Shu T. Lai and published by Princeton University Press. This book was released on 2012 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: As commercial and military spacecraft become more important to the world's economy and defense, and as new scientific and exploratory missions are launched into space, the need for a single comprehensive resource on spacecraft charging becomes increasingly critical. Fundamentals of Spacecraft Charging is the first and only textbook to bring together all the necessary concepts and equations for a complete understanding of the subject. Written by one of the field's leading authorities, this essential reference enables readers to fully grasp the newest ideas and underlying physical mechanisms related to the electrostatic charging of spacecraft in the space environment. Assuming that readers may have little or no background in this area, this complete textbook covers all aspects of the field. The coverage is detailed and thorough, and topics range from secondary and backscattered electrons, spacecraft charging in Maxwellian plasmas, effective mitigation techniques, and potential wells and barriers to operational anomalies, meteors, and neutral gas release. Significant equations are derived from first principles, and abundant examples, exercises, figures, illustrations, and tables are furnished to facilitate comprehension. Fundamentals of Spacecraft Charging is the definitive reference on the physics of spacecraft charging and is suitable for advanced undergraduates, graduate-level students, and professional space researchers.
Book Synopsis Spacecraft Charging Model by : P. Tsipouras
Download or read book Spacecraft Charging Model written by P. Tsipouras and published by . This book was released on 1979 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ambient plasma environment at geosynchronous orbit is assumed to be represented by a two-component Maxwell-Boltzmann particle distribution. Given this, the equations for ambient electron and ion currents to the spacecraft are easily integrated. Likewise, the secondary and backscattered currents can be expressed as integrals. The potential at which the currents balance gives the potential between the spacecraft and ambient plasma. The model is compared with actual data from ATS-5 and is found to agree within plus or minus 1, 200 V over a range of 0 to minus 10,000 V. The model is readily applicable to the simple environmental model of Garrett and DeForest (1979) and can be calibrated to any given satellite. Simple algorithmic expressions are also developed for the backscattered and secondary currents as a function of temperature and potential which promise a significant decrease in computer time without a significant loss in accuracy.

Book Synopsis Spacecraft Charging Model Validation/Test Evaluation Status Report, CDRL A009 by : Edward E. O'Donnell
Download or read book Spacecraft Charging Model Validation/Test Evaluation Status Report, CDRL A009 written by Edward E. O'Donnell and published by . This book was released on 1980 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the primary objectives of the cooperative NASA/Air Force Spacecraft Charging Investigation is to ensure that validated analytical models and test techniques are available for the assessment of spacecraft interactions with the space environment. Models must be capable of predicting the degradation (permanent damage or anomalous behavior) of spacecraft due to the environment. Also, test techniques must be developed for the purposes of providing input data for the models, or for certifying that the spacecraft fulfills its design requirements. This report is an update to the Model Validation/Test Evaluation Status Report (CDRL 006A2) submitted August 1979 by SAI. In the past year, p78-2 data have been integrated into an environmental Atlas. NASCAP predictions have been compared with the P78-2 SSPM sample measurements. Two major electron spraying experiments have been conducted on geometric spacecraft models for which coupling predictions have been made. A quasi-static model of the SGEMP code SABER has been developed and exercised, and significant work has been reported on the emission of current during discharges.
Book Synopsis Charging of Spinning Spacecraft by : Allen G. Rubin
Download or read book Charging of Spinning Spacecraft written by Allen G. Rubin and published by . This book was released on 1979 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has become possible to calculate the effects of spin rate on charging only since the advent of the NASCAP three-dimensional computer simulation code. These spin effects are surveyed here for the first time. There is not only a dramatic difference in potential distribution between a three-axis stabilized and a spinning satellite, but also the case of slow spin at 1 rpm is shown to constitute a distinct intermediate case, asymptotic to the rapid spin case but with appreciable voltage modulation around the spin equator.

Book Synopsis Spacecraft Potential Calculations by : Henry Berry Garrett
Download or read book Spacecraft Potential Calculations written by Henry Berry Garrett and published by . This book was released on 1978 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple model for calculating the potential on a spacecraft by balancing the currents to and from the spacecraft surface is developed. The model, calibrated using ATS-5 plasma data during periods when the satellite was in the earth's shadow, is used to predict potentials on a shadowed, electrically isolated surface at geosynchronous orbit as a function of local time. Potentials are also predicted as the spacecraft moves into and out of the earth's shadow. The results indicate accuracies of + or - 800 V over a range of 10,000 V. (Author).

Book Synopsis Spacecraft Charging at Geosynchronous Orbit by : Henry Berry Garrett
Download or read book Spacecraft Charging at Geosynchronous Orbit written by Henry Berry Garrett and published by . This book was released on 1978 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid variations in spacecraft potential are observed on entry and exit from the earth's shadow. Generalized equations, based on elementary plasma probe theory, are developed which make quantitative estimates of these potentials as a function of satellite position in the earth's penumbra, and are compared with data from the ATS-5 and ATS-6 geosynchronous satellites. The agreement between the observations and the predictions results from the approximate constancy of the ratio of the ambient ion to electron current during injection events. Due to the significant size and shape differences of the ATS-5 and ATS-6 satellites, the results are applicable in many space physics situations such as estimating the effects of electron beams on satellite potential and of spacecraft charging on very large space structures.
