Indian Space Research Organization (ISRO)

Indian Space Research Organisation (ISRO), was founded in 1969 to develop an independent Indian space program. Its headquarters are in Bangalore. ISRO’s chief executive is a chairman, who is also chairman of the Indian government’s Space Commission and the secretary of the Department of Space.

The Indian Space Research Organisation (ISRO) operates through a countrywide network of centres. Sensors and payloads are developed at the Space Applications Centre in Ahmedabad. Satellites are designed, developed, assembled, and tested at the U R Rao Satellite Centre (formerly the ISRO Satellite Centre) in Bangalore. Launch vehicles are developed at the Vikram Sarabhai Space Centre in Thiruvananthapuram. Launches take place at the Satish Dhawan Space Centre on Sriharikota Island, near Chennai. The Master Control Facilities for geostationary satellite station keeping are located at Hassan and Bhopal. Reception and processing facilities for remote-sensing data are at the National Remote Sensing Centre in Hyderabad. ISRO’s commercial arm is Antrix Corporation, which has its headquarters in Bangalore.

In 1979, ISRO conducted the first tests of its own homegrown orbital rocket, the Satellite Launch Vehicle-3 (SLV-3). The four-stage vehicle was capable of placing payloads up to 88 lbs. (40 kilograms) into orbit. SLV-3 successfully launched for the first time on July 18, 1980, making India the sixth nation to achieve spaceflight. It carried the Rohini-1 satellite, an experimental satellite developed to test components that could be used in space.

ISRO has launched several space systems, including the Indian National Satellite (INSAT) system for telecommunication, television broadcasting, meteorology, and disaster warning and the Indian Remote Sensing (IRS) satellites for resource monitoring and management. The first INSAT was launched in 1988, and the program expanded to include geosynchronous satellites called GSAT. The first IRS satellite was also launched in 1988, and the program developed more-specialized satellites, including the Radar Imaging Satellite-1 (RISAT-1, launched in 2012) and the Satellite with Argos and Altika (SARAL, launched in 2013), a joint Indian-French mission that measures ocean wave heights. ISRO subsequently developed three other rockets: the Polar Satellite Launch Vehicle (PSLV) for putting satellites into polar orbit, the Geostationary Space Launch Vehicle (GSLV) for placing satellites into geostationary orbit, and a heavy-lift version of the GSLV called the GSLV Mark III or LVM. Those rockets launched communications satellites and Earth-observation satellites as well as missions to the Moon (Chandrayaan-1, 2008; Chandrayaan-2, 2019) and Mars (Mars Orbiter Mission, 2013). ISRO plans to put astronauts into orbit in 2021.
