The Indian Space Research Organisation (ISRO) is India’s national space agency, operating under the Department of Space, which is directly overseen by the Prime Minister of India. Established in 1969, ISRO has advanced significantly and plays a crucial role in various fields such as telecommunications, meteorology, navigation, and disaster management.
Key Milestones in ISRO’s History
- Founding (1969): ISRO was founded by Dr. Vikram Sarabhai, who is often called the father of the Indian space program. The organization was established to harness space technology for India’s development.
- First Satellite (1975): ISRO launched its first satellite, Aryabhata, on April 19, 1975, from the Soviet Union. This marked India’s entry into the space age.
- Launch Vehicles:
- SLV-3 (1980): India’s first experimental satellite launch vehicle successfully placed the Rohini satellite into orbit.
- ASLV (1992): This vehicle improved payload capacity and reliability.
- PSLV (1994): The Polar Satellite Launch Vehicle became ISRO’s workhorse, known for its reliability in launching satellites into polar orbits.
- GSLV (2001): The Geosynchronous Satellite Launch Vehicle was developed to enhance payload capacity and performance.
- Satellite Programs:
- INSAT Series: Launched since the 1980s, these multipurpose satellites provide services in telecommunications, broadcasting, meteorology, and search and rescue operations.
- IRS Series: The Indian Remote Sensing satellites launched for agricultural, forestry, land-use mapping, and disaster management.
- NavIC: India’s regional navigation satellite system, operational since 2018, provides accurate positioning services to users in India and the surrounding region.
- Interplanetary Missions:
- Chandrayaan-1 (2008): India’s first mission to the Moon, which discovered water molecules on the lunar surface.
- Mangalyaan (2014): The Mars Orbiter Mission made India the first country to successfully enter Mars’ orbit on its maiden attempt and the first Asian nation to reach Mars.
- Recent Developments:
- Chandrayaan-2 (2019): Aiming for a soft landing on the lunar surface; however, the lander lost communication during descent.
- Gaganyaan: India’s ambitious human spaceflight program aims to send Indian astronauts to space by 2024, showcasing ISRO’s capabilities in human spaceflight.
- Chandrayaan-3 (2023): Successfully landed on the Moon, marking India as the first country to land near the lunar south pole.
