BENGALURU: The Indian Space Research Organisation (ISRO) officially released the first set of scientific data from Aditya-L1, India’s space-based solar observatory, to the global scientific community.
The release coincides with the first anniversary of the spacecraft’s successful positioning in its halo orbit around the Sun-Earth L1 point.

TOI first reported that ISRO would release the data in its January 7 edition. ISRO Chairman S Somanath unveiled the comprehensive dataset, which includes observations from all seven remote sensing and in-situ experiments aboard the spacecraft.
The data release event brought together 40 leading scientists, academics, and students from 15 universities and research institutions across India. Following the release, a payload performance appraisal meeting featured detailed presentations from principal investigators of the seven onboard experiments, along with discussions on mission configuration and data archival processes.
“This marks a crucial step forward in India’s solar, heliophysics, and space weather research,” ISRO said. The gathering also focused on strategies to develop India’s indigenous space weather research and prediction programme, emphasising the integration of ground-based data with Aditya-L1 observations for a comprehensive understanding of Sun-Earth connections.
Researchers and students worldwide can now access the Aditya-L1 datasets through the Indian Space Science Data Centre (ISSDC) portal. ISRO has made the data available via multiple access points, including the main ISSDC website and the PRADAN portal, encouraging broad scientific participation and utilisation of these valuable resources.
