ISRO Successfully Launches India’s Heaviest Communication Satellite CMS-03 from Sriharikota. India’s space ambitions took a giant leap forward on November 2, 2025, as the Indian Space Research Organisation (ISRO) successfully launched CMS-03, the heaviest communication satellite ever launched from Indian soil. The satellite, weighing 4,410 kg, was flown aboard the latest LVM3-M5 rocket, known in ISRO parlance as ‘Bahubali’ for its heavy-lift capabilities. This multi-band communication satellite is designed to provide enhanced services over a wide oceanic region including the Indian landmass. Placed precisely into the Geosynchronous Transfer Orbit (GTO), CMS-03 replaces the older GSAT-7 series of satellites that have been operational since 2013. The LVM3-M5, a three-stage launch vehicle equipped with indigenous technology, including the powerful cryogenic C25 stage and solid motor strap-ons (S200), ensured the flawless deployment of the satellite. This launch marks a perfect 100% success rate for all eight LVM3 missions by ISRO, reaffirming India’s prowess in advanced space technology. ISRO Chairman V Narayanan lauded the mission’s success amidst challenging weather conditions and emphasized the ‘Atmanirbhar Bharat’ spirit embodied by this indigenous effort. With a mission life of at least 15 years, CMS-03 is poised to bolster India’s communication and strategic satellite infrastructure substantially.

However, the success of LVM3 now places India on the forefront of heavy satellite launches, greatly enhancing self-reliance in space technology. This mission follows ISRO’s landmark Chandrayaan-3 success in 2023 and paves the way for future ambitious projects including the upcoming human-rated HRLV launch vehicle for the Gaganyaan mission.
