The Indian Space Research Organization (ISRO) has successfully deployed its inaugural imaging satellite into geosynchronous orbit, signaling a recovery for the nation’s space program after a mission failure earlier this year.
Lift-off occurred at 2:55 a.m. local time (2125 UTC) from the Satish Dhawan Space Center in Sriharikota, aboard a Geosynchronous Satellite Launch Vehicle (GSLV). Approximately 18 minutes after ignition, ISRO confirmed that the EOS-05 Earth observation satellite had achieved its designated sub-geosynchronous transfer orbit.
This mission represents the 19th flight for India’s GSLV rocket and carries significant weight as ISRO’s first successful launch of 2026. It follows a setback in January, when a Polar Satellite Launch Vehicle failed to place 16 satellites into their intended orbits.
WEighing over 2,300 kilograms, EOS-05 is the heaviest payload ever carried by a GSLV. Designed to operate at an altitude of approximately 36,000 kilometers, the satellite will match Earth’s rotational speed, allowing it to provide frequent imagery of large areas for Earth observation and monitoring purposes.
Following the launch, ISRO Chairman V Narayanan confirmed the satellite’s status, stating, “The health of the satellite is perfectly alright.”
Prime Minister Narendra Modi praised the achievement on X, describing it as a reflection of the “excellence, innovation and growing capabilities that define India’s space sector.” He added that the successful deployment of the GSLV-F17 carrying EOS-05 was “yet another outstanding achievement” and a point of national pride.
Great recovery for ISRO. That January PSLV failure was tough to watch, but they bounced back strong with EOS-05.
2,300 kg is heavy for a GSLV payload. I wonder how the cryogenic stage handled the extra mass during orbital insertion.
Prime time imagery at 36,000 km is a game-changer for monitoring India’s borders and disaster response. Finally.
Modi’s X post is classic, but can we talk about the engineering grit it took to fix whatever went wrong in January?
18 minutes to sub-geosynchronous orbit feels quick. Did they cut the standard coast phase short, or is the transfer trajectory more efficient now?
