SLV-III stands for Satellite Launch Vehicle-III. It is a launch vehicle developed by the Indian Space Research Organisation (ISRO) to launch satellites into orbit. The SLV-III was India's first indigenous launch vehicle and was developed during the 1970s.
The SLV-III was a four-stage rocket that stood 22 meters tall and weighed 17 tonnes. It was designed to place a 40 kg satellite into a low-earth orbit at an altitude of about 400 km. The rocket used solid fuel for the first and second stages and liquid fuel for the third and fourth stages. The SLV-III had a single engine in its first stage, four strap-on boosters in the second stage, and two engines in the third stage.
The first test launch of the SLV-III was conducted on July 18, 1980, from the Sriharikota launch site. However, the mission was not entirely successful, and the satellite failed to reach orbit due to a malfunction in the control system of the fourth stage. The second test launch of the SLV-III was conducted on July 18, 1983, and was successful in placing the Rohini satellite into orbit, making India the seventh country in the world to launch its satellite into orbit using its own launch vehicle.
The SLV-III program was later superseded by the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV), which are more advanced and capable launch vehicles developed by ISRO. Nevertheless, the SLV-III played a crucial role in establishing India's space capabilities and laying the foundation for future space missions.
