Engineering and science aspects of Chandrayaan I

India has recognized the potential of space science and technology for the socio-economic development of the society during the early days of space era and embarked upon development of an ambitious space program. Over the last three decades, India has achieved significant progress in design, development and operation of space systems, as well as in using the systems for societal applications like telecommunication, television broadcasting, meteorology, disaster warning and natural resources survey and management. The Indian space program has become largely self-reliant with capability to design, build and launch its own satellites using indigenously designed and developed launch vehicles, for providing space services to the country.
