| Abstract | Electrostatics is one of the major concerns of spacecraft technology. Space is filled with hot and low-density plasma building up high differential voltages resulting in electrostatic discharges, sometimes causing an anomalous behavior of spacecraft electronics. The interaction of the satellite with its environment induces a static charge of the various materials which it is made of. The flow and the evacuation of the charges would require a conductive satellite. Unfortunately, the reality is different and satellites are covered with dielectric materials highly resistant for thermo-optic specific purpose. It is resulting in an absolute charge value of the structure of the satellite and in a differential charge built-up between its components that can be at the origin of electrostatic discharges which consequences can end up in the loss of the satellite itself. Typical anomalies are reviewed; it is shown how they can be recognized as consequences of environmental induces discharges. The distribution of charges over different parts of the spacecraft is depending of ambient conditions: plasma temperature and density and sun illumination. Surface and internal charging are possible; they result in dielectric or metal arcing discharges. Understanding of charging phenomena allows us to define mitigation techniques by controlling charging, electromagnetic interference. Finally, we end with the presentation of what it is done in France and in Europe though activities in the domain of space environment in order to take into account problems in a more general context. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
