Sky-High Triumph: ISRO’s GSLV-F17 Successfully Deploys EOS-05, India’s First Geosynchronous Eye in the Sky
Summary: India now has an unblinking, 24/7 "Eye in the Sky" 36,000 kilometers above the planet! Early on September 4, 2026, ISRO’s GSLV-F17 rocket pierced the night sky from Sriharikota, placing the game-changing EOS-05 satellite into orbit—giving the nation uninterrupted, real-time monitoring capabilities across its landmass and oceans.
Sriharikota | September 04, 2026: Ending a long launch hiatus in spectacular fashion, the Indian Space Research Organisation (ISRO) successfully launched the GSLV-F17/EOS-05 mission from the Second Launch Pad at the Satish Dhawan Space Centre at 2:55 AM IST today.
The 51.7-meter-tall GSLV-F17 heavy-lifter precisely injected the 2,367 kg EOS-05 spacecraft into its intended Sub-Geosynchronous Transfer Orbit (Sub-GTO). From here, onboard propulsion systems will guide the satellite to its permanent home in Geosynchronous Orbit, roughly 36,000 km above the equator.
This mission marks a monumental leap for Indian space technology, placing the country’s first-ever continuous Earth observation imaging satellite into high orbit.
"I am very happy to announce that the GSLV-F17 vehicle has successfully and precisely injected the advanced Earth observation satellite EOS-05 into the required orbit," declared ISRO Chairman Dr. V. Narayanan shortly after liftoff.
PM Modi Hails Historic Milestone
Prime Minister Shri Narendra Modi congratulated ISRO scientists and the Indian space industry, calling the feat an outstanding national achievement. Taking to X (formerly Twitter), the Prime Minister shared:
"Yet another outstanding achievement by ISRO and a proud moment for our nation. The successful launch of GSLV-F17 carrying EOS-05, India’s first-ever imaging satellite from Geosynchronous orbit, is a reflection of the excellence, innovation and growing capabilities that define India’s space sector.
The growing partnership between ISRO and Indian industry is adding new strength and scale to our space programme and expanding India’s capabilities across the entire space ecosystem."
Why EOS-05 is a Revolutionary Game-Changer
Unlike typical Earth-observation satellites residing in Low Earth Orbit (LEO) that pass over India only a few times a day, EOS-05 moves in tandem with the Earth’s rotation. This grants it a constant vantage point over the Indian subcontinent.

Frequently Asked Questions (FAQs)
Q1: What makes ISRO's EOS-05 satellite unique?
👉 EOS-05 is India's first dedicated Earth imaging satellite stationed in Geosynchronous Orbit (~36,000 km altitude). Unlike satellites that move past regions periodically, EOS-05 stays in a fixed position relative to India for uninterrupted, round-the-clock imagery.
Q2: Which rocket launched EOS-05 into space?
👉 The spacecraft was launched aboard ISRO’s GSLV-F17 rocket (Geosynchronous Satellite Launch Vehicle) from the Satish Dhawan Space Centre in Sriharikota on September 4, 2026.
Q3: How will EOS-05 benefit everyday citizens?
👉 By transmitting updated imagery every 5 to 30 minutes, EOS-05 dramatically improves early warning systems for natural disasters like cyclones, floods, and landslides, giving response teams critical time to save lives.
