| Abstract | The idea of a tethered-satellite-system (TSS) has been tested twice on the Space Shuttle in the past few years, however both failed. It is desirable to study the complicated dynamics of TSS more deeply. During the deployment phase or the retrieval phase of TSS operation, the length of the tether is varied slowly. This process may lead to a suitable application of the theory of adiabatic invariance. In short, adiabatic (or asymptotic) invariance is a quantity that is almost invariant when some parameter of the physical system is slowly changed. We compute an adiabatic invariance for an approximate model of a TSS during deployment/retrieval mode. It is observed that as the length of the tether becomes larger slowly (deployment mode), the amplitude of the oscillation becomes smaller. On the other hand, if the tether is shortened (retrieval mode), the oscillation becomes larger. This observation coincides with the assertion that the dynamics is stable during the deployment mode, but unstable during the retrieval mode. |

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.
