ISRO and its achievements – 1150 Words Essay

Preface

All the space missions of the Government of India (Missions of ISRO) are operated under ISRO. All space launches and satellites are also tested from time to time under the ISRO organization. ISRO has played an important role in the development of India and in the race of astronomy with other countries. ISRO has contributed immensely not only in its own country but also in the launch of other countries. Due to its successful missions, ISRO has established its dominance around the world in the field of astronomy.

Establishment of ISRO (Establishment of ISRO)

After Sputnik, the first satellite launched by Russia with the Soviets in 1957, India’s first Prime Minister Jawaharlal Nehru realized the need for space programs in the future. In 1961, space research was placed under the supervision of Homi Bhabha, chairman of the Department of Atomic Energy, after which the “Indian National Committee for Space Research” was formed in 1962, in which Dr. Vikram Sarabhai was appointed as the chairman.

The foundation of the Indian space program was laid under the leadership of Dr. Vikram Sarabhai, the father of Indian space programmes. When the Indian Space Research Organization was established on 15 August 1969, its name was “Indian National Committee for Space Research (INCOSPAR)”.

role of ISRO (Role of ISRO)

The responsibility of conducting space programs in India has been on the shoulders of ISRO since the year 1962, which ISRO has done very honestly. ISRO is headquartered in Bangalore and the sensor and payload are developed at the Space Applications Center in Ahmedabad. The reception and processing facilities for remote sensing data are at the National Remote Sensing Center in Hyderabad.

The UR Rao Satellite Center in Bangalore, formerly the ISRO Satellite Centre, designs, assembles, builds and tests satellites. Launch vehicles for launching satellites are developed at the Vikram Sarabhai Space Center in Thiruvananthapuram. The satellites are launched from the Satish Dhawan Space Center on Sriharikota Island near Chennai. Arrangements like master control for maintenance of Geostationary Satellite Station are located at Hassan and Bhopal.

Achievements of ISRO (Achievments of ISRO)

ISRO has developed many space systems including meteorology, telecommunications, television broadcasting and disaster warning systems. The first satellite “Aryabhata” built by ISRO on 19 April 1975 was launched by the Soviet Union. The satellite “Rohini” was put into orbit on 18 July 1980 by the Satellite Launch Vehicle 3, the first launch vehicle manufactured by India. ISRO launched the first INSAT satellite and the first IRS satellite in 1988.

ISRO launched Radar Imaging Satellite-1, RISAT-1 in 2012. ISRO has developed the Polar Satellite Launch Vehicle, to place satellites into polar orbits and the Geostationary Space Launch Vehicle to place satellites into geostationary orbits. Chandrayaan-1 was launched in 2008 and Chandrayaan-2 in 2019 to observe the Moon by ISRO. ISRO gained worldwide fame with the successful launch of the Mars Orbiter Mission in 2013.

Major launches of ISRO (Major Launches of ISRO)

The first rocket was launched by ISRO on 21 November 1963. Space Science and Technology Center at Thumba was established in 1965 and Ugrah Communication Systems Center at Ahmedabad was established in 1967. The Space Commission and the Department of Space were established in 1972. Bhaskar-1 was launched in 1979. Bhaskar-2 was launched in 1981. In 1984, Rakesh Sharma became the first Indian astronaut in a joint space mission between India and the Soviet Union. The SROSS-1 satellite was launched in 1987. INSAT-1D was launched in 1990. INSAT-2D was launched in 1997. INSAT-3B was launched in the year 2000 and GSALV D-1 was launched in 2001.

ISRO launch vehicle (ISRO Launch Vehicle)

The Satellite Launch Vehicle project was started under the leadership of APJ Abdul Kalam to launch satellites in the year 1970. The goal of the project was to place a payload of 40 kg at an altitude of 400 km, but the first launch of SLV-3 in August 1979 failed. After a few years, from time to time, ISRO developed many types of launch vehicles, which are as follows-

  • polar satellite launch vehicle (Polar Satellite Launch Vehicle)

It was used for the first time in 1994, it is the second generation launch vehicle. With its help, from 1994 to 2017, about 257 satellites have been launched, including 48 Indian and 209 foreign satellites. PSLV has become more efficient and reliable after the successful launch of Chandrayaan-1 and Mars Orbiter spacecraft in 2008.

  • geostationary satellite launch vehicle (Geostationary Satellite Launch Vehicle)

It is also known as Geosynchronous Launch Vehicle Mark 2. It was first used for the first time in 2001. It is used to place it in geostationary orbit at an altitude of 2 tonnes and 36000 km. A total of 13 launches have been made by it so far, of which 4 have been successful.

  • Enhanced Satellite Launch Vehicle (Augmented Satellite Launch Vehicle)

This launch vehicle was used in the 1980s. It used to launch 150 kg satellites. It is a five stage solid fuel rocket. This launch vehicle is no longer in use.

  • Geostationary Satellite Launch Vehicle Mark 3 (Geostationary Satellite Launch Vehicle Mark 3)

The capability of this launch vehicle is twice that of Geosynchronous Launch Vehicle Mark 2. It was first used in 2014. Chandrayaan-2 was launched by this.

Upcoming Projects of ISRO (Upcoming Projects of ISRO)

ISRO is planning to do some select projects in the coming years, which are Chandrayaan-3, Aditya-1, Indian Venus Orbiter Mission, Mangalyaan-2 and Jupiter Mission. It has been decided to launch Mangalyaan-2 in 2024. ISRO is moving towards developing the Reusable Launch Vehicle-Technology Demonstrator (RLV-TD) in the future. Wing Reusable Launch Vehicle technology will be used in this. Integrated launch vehicle is also being developed by ISRO.

Conclusion

ISRO has achieved a different position in the world by the successful launches of its space projects. There was a time when India had to spread its hands in front of countries like America and Russia to launch its satellites, but today is the day when India itself launches satellites of all countries like America and Russia from its launch vehicle. Along with itself, ISRO has proudly raised the name of Bharat Varsh. It is an honor in itself to become a scientist of ISRO today.
