Background:

• Space activities in India began with the establishment of the Indian National Committee for Space Research (INCOSPAR) in 1962. In the same year, work on establishment of Thumba Equatorial Rocket Launching Station (TERLS) near Thiruvananthapuram was also started.
• ISRO was formed on 15th Aug 1969, and superseded INCOSPAR with an expanded role. In 1972, Space Commission and Department of Space (DOS) were constituted by the GoI, and ISRO was brought under DOS.
• ISRO is the space agency of India. It is involved in science, engineering, and technology to harvest the benefits of our space for India and mankind. It has established major space systems for communication, television broadcasting, and remote sensing. It has also developed satellite launch vehicles like PSLV, GSLV, LVM-3 etc. It also contributes to science and science education in the country. It has launched Indian’s NAVIC, Chandrayaan, MOM-1, Aditya-L1 and several other incredible missions.
• Space Commission formulates the policies and oversees the implementation of the Indian Space Program to promote development and application of space science and technology for the socio-economic benefit of the country.
• DOS implements these programs through ISRO and other associated organizations:

The Major establishments of DOS and their area of activities are:

A) Vikram Sarabhai Space Centre (VSSC):

• It undertakes multidisciplinary R&D activities in new domains of human science and technology while conforming to high standards of reliability and human safety.
• It is currently focused on Gaganyaan mission and is working on end-to-end mission planning, development of orbital module, life support systems, selection and training of astronauts etc.
• It is currently operating from ISRO-HQ campus, Bengaluru.

G) National Remote Sensing Centre

• It is responsible for establishment of ground centres for receiving satellite data, generation of data products, aerial remote sensing data acquisition, dissemination to the users, development of techniques for remote sensing applications including disaster management support, geospatial services etc.

H) ISRO Propulsion Complex (IPRC)

• Located in Mahendragiri, it is responsible for assembly, integration and testing of liquid propulsion systems for operational and developmental launch vehicles.
• It is also responsible for qualification, testing and acceptance of liquid engines, cryogenic engines, spacecraft engines etc.

I) ISRO Telemetry, Tracking and Command Network (ISTRAC)
