Indian Space Research Organisation and its innovative resarch

Indian Space Research Organization is a premier space research institute of India. The ISRO brought the revolution in the sectors of India, including agriculture to communication since decades by showing sustained growth in the space technology. A brief article about the path covered by ISRO in space research

India, the country which having tremendous will in its heart, great excellence in the brain, but suffer due to lack of proper implementation of thoughts. The nation which having rich history and potential knowledge suffered about 500 years due to attack of the outsiders and got independence in 1947. Due to the tremendous support of first prime minister of India, Pandit Jawaharalal Nehru to scientific and technological development, in-spite of large number of problems related socio-economic , religious and security, the science excelled in India. The Indian Space Research Organization(ISRO) is one of number of premier Research Institutes along with the IISc, BARC itc., which seriously undergone in the space research.

With the setting up of Indian National Committee for Space Research (INCOSPAR) under the chairmanship of Dr. Vikram Sarabhai in 1962, the Indian space program started. The committee strive hard to achieve self reliance in developing capability to build and launch communication satellites for television broadcast, telecommunications and meterological applications; remote sensing satellites for management of natural resources.

By the great vision of Dr. Vikram Sarabhai regarding the space technology to play great role in the national development and also thinking to solve the problems of common man, the ISRO established in the year 1969, with the number of projects in the hand one of them is Rohini Sounding Rocket (RSR), the success in the projects brought great confidence to take additional innovative work in space technology.

On first June 1 1972, the ISRO is handed over to the Department of Space (DoS), the Space Commission formed to implement the space program effectively. With this the ISRO started to build the launching vehicles to launch satellite. In 19880 ISRO built its first launching vehicle called SLV (Satellite Launching Vehicle) by 1980. The SLV was a multiple rocket launching vehicle which could carry a pay load of about 40 kg to 500km height.

Augmented Satellite Launch Vehicle (ASLV) demonstrated the the achievement of developing the critical space technologies. The first developmental flight took place on March 24, 1987 and second on 13 July 1988. This vehicle configured as a five stage with 23.8 m tall and lift of weight 40 tonnes. It was constructed to take the satellite of 150 Kg to space and encircle the earth at the height of 400km. ASLV-D3 launched in May 20, 1992 with the satellite SROSS-C of weight 106kg and put into orbit of 25x430 orbit. In May 4th 1994, SROSS-C2 weight 106 kg launched with same vehicle which having two pay loads. It served for seven years and gave valuable inputs for further development.

In between this the space program of India was also continued with the the foreign developed space vehicles of USSR and France. The Aryabhata satellite launched from USSR in 1975 and INSAT (Indian Satellite) series started in 1983. They contributed lot in the field of communication, broadcasting , metrology etc. The INSAT are the geostationary satellites, at that time Indian Technology have not reached to take large weight to the geo stationary orbit hence, we were depend on the other developed countries.

In later stage the ISRO, continuing in the direction to become self sufficient it produced another advanced launching vehicle called Polar Satellite Launching Vehicle (PSLV), is first operational launch vehicle for ISRO, it is 44.4 m tall and has lift off weight 295 tonnes.. It is capable of taking 1600 kg satellites to 620 km sun-synchronous polar orbit and 1050kg to geo-synchronous transfer orbit. Till April 2011 PSLV launched 17 satellites to their orbit, it has multi payload, multi mission capability in single launch. The PSLV is used in recent ISRO's ambitious and successful mission of Chandrayaana. The PSLV also used in the launching the IRS (Indian Remote Sensing) satellites.

April 28, 2008 was a great day for the Indian space history, that India's polar rocket PSLV – C9 successfully placed India's remote sensing satellite Cartosat – 2A along with nine other satellites, and proved only second country of the world which launched 10 satellites or more into orbit. Before this only the Russia put 13 satellites into the orbit at a time in April 2007.

Geosynchronous Satellite Launch Vehicle (GSLV)-Mark I and II, it is 3 stage satellite with carrying capacity of 2000 to 2500kg in to Geosynchronous transfer orbit (GTO). It is 49 meter tall and having lift of weight 414 tonne. Its second state has liquid engine and third stage is cryo (low temperature) stage. The latest attempt of GSLV to put some satellite is failed that took place 25 December 2010.

Now the GSLV mark III is under construction, which is capable of carrying (4000 kg to 5000kg) INSAT – IV series satellite, which may schedule to launch in 2012.
