Why this matters now
Sarabhai is the most-tested figure for India’s space programme. PRL (1947), TERLS Thumba (1963), ISRO founding (1969), SITE (1975), and his vision of “application of space science to the problems of man and society” — not space prestige but social development.
PRL Ahmedabad (1947) and cosmic-ray research
Trained at Cambridge (under C.V. Raman’s recommendation) and later at IISc, Sarabhai’s PhD work was on cosmic-ray time variations. He returned to India in 1947 and founded the Physical Research Laboratory (PRL) at Ahmedabad on 11 November 1947 — a private trust (later DAE) for cosmic-ray and space-physics research. PRL remains India’s premier planetary-science institution.
Thumba (1963), ISRO (1969)
Convinced by Homi Bhabha (his mentor at AEC) that India needed a space programme, Sarabhai established the Thumba Equatorial Rocket Launching Station (TERLS) at Thumba (Thiruvananthapuram, Kerala) in 1962-63 — chosen for its proximity to the magnetic equator. First sounding rocket launched 21 November 1963.
In August 1969 the Indian Space Research Organisation (ISRO) was created from INCOSPAR (Indian National Committee for Space Research, est. 1962), with Sarabhai as its first Chairman. He set the founding vision: “We are convinced that if we are to play a meaningful role nationally, and in the comity of nations, we must be second to none in the application of advanced technologies to the real problems of man and society.”
SITE, death and legacy
Sarabhai conceived the Satellite Instructional Television Experiment (SITE) — using an American ATS-6 satellite to broadcast educational TV to 2,400 villages across 6 states from August 1975 to July 1976 (5 years after his death). It was the world’s largest satellite-broadcast experiment to that point.
He died at Kovalam (Kerala) on 30 December 1971, aged 52. The Vikram Sarabhai Space Centre (VSSC) at Thiruvananthapuram was renamed in his honour. Padma Bhushan 1966; Padma Vibhushan 1972 (posthumous). His son Karthikeya Sarabhai is a noted environmental educator; daughter Mallika Sarabhai is a Bharatanatyam dancer-activist.

From TERLS at Thumba (Thiruvananthapuram, Kerala) on 21 November 1963.
Who succeeded Sarabhai as Chairman of ISRO?
M.G.K. Menon (briefly), then Satish Dhawan (1972-1984).
