Indian space programme (representative image) BENGALURU: August 23, 2023, gave India an image it had waited decades to see: a spacecraft settling on the Moon, its lander and rover beginning work near the lunar south polar region. But the significance of Chandrayaan-3 was perhaps easier to understand if one looked backwards.

Six decades earlier, India was still figuring out how to launch a sounding rocket from a small range at Thumba, near Thiruvananthapuram. There were no Indian satellites, no launch vehicles capable of placing them in orbit, no sprawling network of mission control centres, tracking stations and testing facilities.

The Indian space programme itself did not yet exist in the form we know it today. On Sunday, as India marks National Space Day, the distance between those two moments offers perhaps the clearest measure of how far the programme has travelled.

The journey began in 1962 with the creation of the Indian National Committee for Space Research, or Incospar, and the decision to establish the Thumba Equatorial Rocket Launching Station. The first sounding rocket was launched from Thumba on Nov 21, 1963.

Six years later, on Aug 15, 1969, the Indian Space Research Organisation (Isro) was formed. In 1972, the govt created the Space Commission and the Department of Space, bringing Isro under the latter.

The ambition, however, was never simply to join the global race to space. Vikram Sarabhai’s vision was shaped by a more practical question: what could space technology do for a country that still faced enormous developmental challenges?

That question defined the first phase of the programme. The launch of Aryabhata, India’s first satellite, in 1975 was a technological landmark.

But the same period also saw experiments that revealed how satellites could be used to reach people on the ground. The Satellite Instructional Television Experiment, or SITE, used satellite broadcasting to bring television programmes to remote communities.

This was followed by the Satellite Telecommunication Experimental Project. Earth observation, communication and weather services gradually became as important to the programme as the act of launching a satellite itself.

The 1980s brought another transition: India began learning to build its own means of reaching space. The first experimental flight of the SLV-3 in 1979 failed to place its Rohini payload in orbit.
