Key highlights
Direct fact
In September 2026, ISRO launched the 2,367-kg EOS-05 satellite aboard GSLV-F17 from the Satish Dhawan Space Centre, Sriharikota, and placed it into Sub-Geosynchronous Transfer Orbit about 18 minutes after lift-off.
Key specifics
- GSLV-F17 was the 19th flight of the GSLV launch vehicle.
- The launch took place from the second launch pad at Sriharikota at 2.55 a.m. on September 4, 2026.
- EOS-05 is India’s first imaging satellite designed to monitor Earth from geosynchronous orbit, about 36,000 km above Earth.
