With the COSPAR Vikram Sarabhai Medal, Professor Annapurni Subramaniam has put Indian space science in a position to look to the stars with even greater pride. The Director of the Indian Institute of Astrophysics (IIA) in Bengaluru is the first woman from India to be accorded this distinction, an international honour of the highest order for work done in the field of space research by developing nations.
The 2026 award was handed over at the 46th COSPAR Scientific Assembly in Florence this past August. To those who have been watching India’s expanding footprint in global space science, it is a moment of some import, speaking as much to the rise of Indian women in astrophysics and scientific leadership as it does to Subramaniam’s own record.
A Global Honour, A Historic First for India
Given by the Committee on Space Research, the medal is reserved for those with outstanding contributions to the technology and science of space. In accepting it, Subramaniam joins U.R. Rao, Gurbax Singh Lakhina and Anil Bhardwaj as the fourth Indian so honoured. On a worldwide scale she is merely the third female recipient, making for an achievement that is noteworthy both here and abroad.

Three Decades of Research That Took Her to the Global Stage
Subramaniam has spent the better part of 30 years in stellar physics, her efforts directed at ultraviolet astronomy and the evolution of star clusters and nearby galaxies. Her output is considerable: some 175 papers and 15 PhD students mentored.
Then there is the matter of AstroSat’s Ultraviolet Imaging Telescope (UVIT). As its calibration scientist, she was instrumental in the in-orbit verification of the instrument’s performance. That has allowed for the study of celestial bodies in ultraviolet wavelengths which the Earth’s atmosphere would otherwise make inaccessible.
From Breaking Barriers at IIA to Making History Globally
She set a precedent within her own institution in 2019 as the first woman to take the helm of the IIA. In the years since, she has been behind the institute’s part in key projects, from solar to extragalactic studies, and has not shied away from involving the public and students in the story of missions like the 2015 AstroSat launch.[Text Wrapping Break][Text Wrapping Break]In many ways, the medal is more than a personal trophy. It is an acknowledgement of what India is bringing to the table in terms of instrumentation and space-based astronomy, and of the place women are carving out in our scientific establishments. For the young researchers who will follow, it sends a clear message: that one can do more than just enter the arena of space science, one can lead it and write history in the process.
