On the Athashri podcast, Dr. Kale recounts his journey from early schooling in Pune and college at Ferguson to pursuing physics and space communications after Sputnik-1, joining PRL in 1960, tracking satellites, and working under Dr. Vikram Sarabhai’s guidance.
He describes the formation of ISRO, training in the USA in 1963, and the establishment of Equatorial Rocket Launching Station to study upper-atmosphere currents and links to monsoon, while maintaining a focus on communication satellites and geostationary orbit.
He explains India’s launch-vehicle evolution from sounding rockets to SLV-3 (successful in 1980 after earlier failures), the safety- and coordination-heavy launch process, propellant development challenges and extensive static testing, and later progress toward human spaceflight (Gaganyaan) and a planned Indian space station around 2036–37. He also details the NASA ATS-based SITE experiment bringing educational TV to 2,400 villages in 1975–76, his retirement into science-education initiatives, concerns about scientific temper and lab access, discussion of asteroid/meteor monitoring, and technology needs in senior living such as fall detection and better communication devices.
