India launches EDUSAT the ultimate satellite for educational services (September 2004). India has become the potential of space science and technology for the socio-economic development of the society soon after the launch of Sputnik by erstwhile USSR in 1957. The Indian space efforts started in the sixties with the establishment of Thumba Equatorial Rocket Launching Station near Thiruvananthapuram for the investigation of ionosphere using sounding rockets. The Indian Space Research Organisation (ISRO), was established in the year 1969 under the Department of Atomic Energy. The Government of India gave fillip to the space activities by formally setting up Space Commission and the Department of Space (DOS) in June 1972 and ISRO was also brought under Department of Space. Over the last three decades, India has achieved an enviable progress in the design, development and operation of space systems, as well as using the systems for vital seryices like telecommunication, television broadcasting, meteorology, disaster warning and natural resources survey and management.

The space programme has become largely self-reliant with capability to design and build its own satellites for providing space services and to launch them using indigenously designed and developed launch vehicles. The successful first test flight of Geosrynchronous Satellite Launch Vehicle (GSLV) from Sriharikota on April 18, 2001 was the most significant milestone of the Indian space programme. The launch unequivocally demonstrated India's capability to place satellites into geo-synchronous transfer orbits. India is among the 6 nations in the world to achieve such a capability. The launch of OS LV is the culmination of efforts of various DOS centres and other institutions that involved complex interfaces between scientific and technological disciplines, industries and research institutions. Another crucial milestone during the year was the succeasfulflight of PSLV-C3 on October 22, 2001 from Sriharikota. In this fifth consecutively successful flight, PSLV placed three satellites-India's Technology Experiment Satellite, TES, Belgian PROBA and German BIRD into their intended polar sun-synchronous orbit. The requircment of a higher orbit for the Belgian PROBA compared to other two satellites was successfully met by a flight manoeuvre. Both German and Belgian satellites were launched under commercial agreements.
