Technological Development during past :

From building the first experimental satellite Aryabhatta in 1975 to the world class operational Indian Remote Sensing (IRS) satellite series on the one hand and the third generation communication satellite INSAT-3 on the other, is indeed an impressive track record by any standards for the 30-year-old Indian Space Research Organization (ISRO). Indian space Programme encompasses research in areas like astronomy, astrophysics, planetary and earth sciences, atmospheric sciences and theoretical physics. Balloons, sounding rockets, space platforms and ground-based facilities support these research efforts. A series of sounding rockets are available for atmospheric experiments. Several scientific instruments have been flown on satellites especially to direct celestial X-ray and gamma-ray bursts Since its establishment, ISRO has achieved numerous milestones. It built India's first satellite, Aryabhata, which was launched by the Soviet Union in 1975. It was built by the Indian Space Research Organisation (ISRO) to gain experience in building and operating a satellite in space. A power failure halted experiments after four days in orbit with all signals from the spacecraft lost after five days of operation. The satellite reentered the Earth's atmosphere on 11 February 1992.In 1980, Rohini became the first satellite to be placed in orbit by an Indian-made launch vehicle, SLV-3. ISRO subsequently developed two other rockets: the Polar Satellite Launch Vehicle (PSLV) for launching satellites into polar orbits and the Geosynchronous Satellite Launch Vehicle (GSLV) for placing satellites into geostationary orbits. These rockets have launched numerous communications satellites and earth observation satellite. In 2008, Chandrayaan-1, India sent its first mission to the Moon.

The Mars Orbiter Mission (MOM), informally called Mangalyaan, is a Mars orbiter launched into Earth orbit on 5 November 2013 by the Indian Space Research Organization (ISRO) which is currently on-route to Mars.


India’s First Mission to Mars Over the years, ISRO has conducted a variety of operations for both Indian and foreign clients. ISRO's satellite launch capability is mostly provided by indigenous launch vehicles and launch sites. Launch Vehicles are used to transport and put satellites or space crafts into space. In India, the launch vehicles development Programme began in the early 1970s. The first experimental Satellite Launch Vehicle (SLV-3) was developed in 1980. An Augmented version of this, ASLV, was launched successfully in 1992. India has made tremendous strides in launch vehicle technology to achieve self-reliance in satellite launch vehicle Programme with the operationalization of Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV). PSLV represents ISRO's first attempt to design and develop an operational vehicle that can be used to orbit application satellites. While SLV-3 secured for India a place in the community of space-faring nations, the ASLV provided the rites of passage into launch vehicle technology for ISRO. And with PSLV, a new world-class vehicle has arrived. PSLV has repeatedly proved its reliability and versatility by launching 64 satellites / space crafts into a variety of orbits so far.
