What is the GSLV-3 rocket?

The Geosynchronous Satellite Launch Vehicle (GSLV) is India’s largest and most powerful rocket, designed to launch heavy satellites into orbit. Developed by the Indian Space Research Organisation (ISRO), the GSLV-III rocket, also known as the LVM3 (Launch Vehicle Mark-3), is the latest and most advanced version of the GSLV series.

The GSLV-III is a three-stage rocket that stands at a height of 43 meters and has a liftoff mass of 640 tons. It is capable of launching payloads of up to 4,000 kg into the geostationary transfer orbit (GTO) and 10,000 kg into the low-earth orbit (LEO). The rocket uses a cryogenic engine in its upper stage, which provides more thrust and fuel efficiency than conventional liquid engines.

The first successful test flight of the GSLV-III took place on June 5, 2017, when it launched the GSAT-19 communication satellite into orbit. This was a significant achievement for ISRO, as it demonstrated the agency’s ability to launch heavier payloads into space and reduced India’s dependence on foreign launch vehicles.

One of the key features of the GSLV-III is its indigenous cryogenic engine, which was developed by ISRO after facing technology denial regimes from other countries. Cryogenic engines are considered the most efficient rocket engines for space launches and use liquid hydrogen and liquid oxygen as propellants. The development of the indigenous cryogenic engine was a significant milestone for ISRO, as it allowed the agency to develop its own launch vehicles without relying on other countries.

In addition to launching communication and remote sensing satellites, the GSLV-III is also capable of launching manned missions into space. ISRO has plans to use the rocket for its upcoming Gaganyaan mission, which aims to send Indian astronauts into space by 2022.

The GSLV-III represents a significant advancement in India’s space program and demonstrates the country’s growing capabilities in the field of space exploration. With its ability to launch heavier payloads and the potential for manned missions, the GSLV-III is poised to play a key role in India’s future space missions and cement the country’s position as a major player in the global space race.
