Isro to launch GISAT-1A in September 2026 after seven-month pause

The Indian Space Research Organisation (Isro) is preparing to launch the GISAT-1A Earth-observation satellite in September 2026, a mission expected to end a nearly seven-month operational pause in the agency’s launch schedule. The exact date of the launch has not been specified.

GISAT-1A is designed for Earth observation. The mission is expected to resume Isro’s regular launch schedule after a period that followed a difficult run for the space agency.

The pause followed, among other developments, the failure of the PSLV-C61/EOS-09 mission in 2025. The mission was unsuccessful because of an anomaly in the rocket’s third stage, according to the available research information.

The upcoming GISAT-1A launch is therefore being planned as Isro prepares to return to regular mission operations. However, no further details on the launch vehicle, launch site or the satellite’s specific observation capabilities have been provided.

The September 2026 timeframe remains the available schedule for the mission. Until Isro specifies a date, the launch should be treated as scheduled for the month rather than as fixed for a particular day.
