ISRO Scripts History with Successful Launch of LVM3-M6 Carrying BlueBird Block-2 Satellite

New Delhi, Dec 2025 : The Indian Space Research Organisation (ISRO) on Wednesday added another historic milestone to its growing list of achievements by successfully launching the LVM3-M6 rocket, carrying the United States’ next-generation BlueBird Block-2 communication satellite, marking a major leap in global space-based connectivity.

Announcing the success, ISRO posted on X, “Mission Success. The LVM3-M6 mission has successfully placed the BlueBird Block-2 satellite into its intended orbit.” The flawless mission once again demonstrated India’s reliability as a global launch partner and underscored ISRO’s expanding capabilities in handling heavy and complex payloads.

Weighing approximately 6,100 kg, BlueBird Block-2 is the heaviest payload ever placed into Low Earth Orbit (LEO) by the LVM3 launch vehicle. This surpasses ISRO’s previous record set during the LVM3-M5 mission, which successfully launched a 4,400 kg communication satellite into Geosynchronous Transfer Orbit (GTO) on November 2. The achievement reflects ISRO’s steady progress in heavy-lift launch technologies.

The BlueBird Block-2 satellite is part of a new generation of advanced communication satellites designed to deliver space-based cellular broadband connectivity directly to standard smartphones, without the need for specialised equipment. Once fully operational, the satellite will support high-speed 4G and 5G services, significantly enhancing global mobile coverage, especially in remote and underserved regions.

The mission marked the sixth operational flight of the LVM3 launch vehicle, India’s most powerful rocket. Standing 43.5 metres tall and powered by two massive S200 solid boosters, the rocket lifted off from the second launch pad at the Satish Dhawan Space Centre, Sriharikota, at 8:55 a.m., following a 24-hour countdown. The launch pad is located about 135 km east of Chennai.

ISRO adopted a cautious and precise approach, delaying the launch by 90 seconds from its original schedule of 8:54 a.m. to ensure mission safety and accuracy. Approximately 15 minutes into the flight, the BlueBird Block-2 satellite successfully separated from the rocket and was injected into its designated orbit at an altitude of around 520 km, as planned.

Developed by US-based AST SpaceMobile, BlueBird Block-2 is among the world’s heaviest commercial communication satellites, with a total mass close to 6.5 tonnes. The satellite arrived in India from the United States on October 19, ahead of extensive integration and testing procedures carried out by ISRO.

Union Minister of State for Science and Technology Dr Jitendra Singh congratulated ISRO, praising the organisation’s consistent success. “Kudos Team ISRO for the successful launch of LVM3-M6 carrying BlueBird Block-2. With the visionary patronage of Prime Minister Narendra Modi, ISRO continues to achieve one success after another, reiterating India’s growing prowess in space technology,” he said in a post on X.

The mission was executed under a commercial agreement between NewSpace India Limited (NSIL)—ISRO’s commercial arm—and AST SpaceMobile. This collaboration highlights India’s increasing role in the global commercial space market, where ISRO is emerging as a preferred and cost-effective launch service provider.

This launch also marks the second major collaboration between ISRO and US space agencies and companies in recent months. Earlier in July, ISRO successfully launched the $1.5 billion NASA-ISRO Synthetic Aperture Radar (NISAR) mission, designed to conduct high-resolution Earth observations capable of penetrating clouds, fog, and ice layers.

AST SpaceMobile has already launched five BlueBird satellites—BlueBird 1 to 5—in September 2024 and plans to expand its constellation further. The company has partnered with over 50 mobile network operators worldwide, aiming to revolutionise mobile connectivity through direct-to-device satellite services.

With the successful launch of BlueBird Block-2, ISRO has once again demonstrated its technical excellence, reliability, and growing stature in the international space arena, reinforcing India’s position as a leading force in advanced space and communication technologies.
