| Abstract | The continued assembly and operation of the International Space Station (ISS) is the cornerstone within NASA's overall strategic plan. As indicated in NASA's Integrated Space Transportation Plan (ISTP), the International Space Station requires shuttle to fly through at least the middle of the next decade to complete assembly of the station, provide crew transport, and to provide heavy lift up and down mass capability. There is a new emphasis for the need to achieve greater efficiency and safety in transporting crews to and from the space station. One concept under discussion to better fulfill this role of a heavy lift carrier, is the transformation of the shuttle to an "unpiloted" autonomous system. This concept would eliminate the loss of crew risk, while providing a substantial increase in payload to orbit capability. When addressing the transformation to an unpiloted shuttle system, numerous hardware, software and procedural changes will be required to both flight and ground systems. Converting the shuttle fleet to an autonomous system will be challenging and expensive. Projected implementation cost estimates for an autonomous shuttle system would be in the low $ billions, depending on the degree of modification and system redundancy required. Although an autonomous shuttle eliminates the risk for loss of crew, the risk to a loss of vehicle or mission success could potentially be increased. Previous shuttle experience in space has demonstrated that the human presence provides an invaluable capability to successfully react to any situation that may arise. This important capability cannot be easily "automated" or replaced. |

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.
