  1. ISRO to launch GSLV-F17/EOS-05 mission on September 4, 2026.
  2. EOS-05 is India's first imaging satellite in geosynchronous orbit.
  3. Mission strengthens India's continuous Earth observation capabilities from space.

ISRO EOS-05 Satellite: The Indian Space Research Organisation (ISRO) is set to launch the GSLV-F17/EOS-05 space mission from the Satish Dhawan Space Centre in Sriharikota. Scheduled for liftoff at 2:55 AM IST on September 4, 2026, the GSLV-F17 rocket will deploy the state-of-the-art EOS-05 spacecraft into a Sub-Geosynchronous Transfer Orbit (Sub-GTO) from the Second Launch Pad.

ISRO Chairman V. Narayanan confirmed that all launch preparations are complete following pre-launch rituals at the Sri Venkateswara Swamy Temple in Tirumala.

The mission represents a major technological leap, strengthening India’s space capabilities by placing its first-ever imaging satellite into a high geosynchronous orbit to continuously observe vast geographical regions.

Strategic Significance of EOS-05 in Geosynchronous Orbit

EOS-05 marks a breakthrough as India’s first imaging satellite positioned in a high geosynchronous orbit (HGO). Unlike low-Earth orbit satellites, this elevated positioning allows the spacecraft to maintain continuous surveillance over vast landmasses, significantly expanding the real-time coverage capacity of India's satellite fleet.
