Overview
- The GSLV-F17/EOS-05 mission is scheduled to lift off from SDSC‑SHAR, Sriharikota at 2:55 AM IST on Friday, September 4, with ISRO streaming the launch and limited public viewing available at the Launch View Gallery.
- GSLV-F17 is the 19th GSLV flight, a three‑stage rocket with an indigenous cryogenic upper stage and a 4‑metre ogive composite payload fairing that will place EOS-05 into a Sub‑Geosynchronous Transfer Orbit.
- After separation in Sub‑GTO, the 2,367 kg EOS-05 spacecraft will use multiple onboard propulsion burns to raise itself to geosynchronous altitude, near 35,786 km above the equator.
- EOS-05, also called GISAT-1A, is designed to provide frequent, near‑real‑time multispectral and hyperspectral imagery with selected‑area revisits in about five minutes and full‑country coverage in roughly 30 minutes at ~42 m resolution.
- The mission carries programmatic weight as a return‑to‑flight milestone after the 2021 GISAT‑1 loss and two PSLV anomalies in 2025–early 2026, and its outcome will influence ISRO's launch confidence and near‑term mission cadence.
