Kolkata’s Quiet Force Propels India to Global Space Leadership: Heritage Alumnus Subhradip Ghosh Orchestrates NISAR Mission’s Historic Launch
Kolkata (West Bengal) [India], August 4: NASA and ISRO’s joint NISAR (NASA-ISRO Synthetic Aperture Radar) Earth observation satellite has lifted off in a landmark mission, and Kolkata-born scientist Subhradip Ghosh played a pivotal role in its success. NISAR will measure Earth’s changing ecosystems and dynamic surfaces – from melting ice sheets to vegetation changes – providing critical data on biomass, sea-level rise and natural hazards. Launched on July 30, 2025 from India’s Satish Dhawan Space Centre, NISAR carries advanced L- and S-band radars and represents the first-ever joint hardware collaboration between ISRO and NASA.
