The Indian Space Research Organisation (ISRO) is scheduled to launch the BlueBird Block-2 satellite today using its LVM3-M6 rocket from the Satish Dhawan Space Centre in Sriharikota. The mission is set to lift off at 8:55 am, with the BlueBird Block-2 satellite expected to separate from the LVM3-M6 rocket about 15 minutes after launch. Weighing approximately 6,100 kilograms, BlueBird Block-2 is the heaviest payload ISRO has placed into Low Earth Orbit (LEO) using the LVM3 rocket. The launch is part of a commercial agreement managed by NewSpace India Limited (NSIL), ISRO’s commercial arm.
Significance for India’s space sector
Today’s mission highlights two major trends in India’s space industry: the rising global demand for direct-to-mobile satellites and the increasing use of LVM3 for commercial contracts. This launch marks LVM3’s third fully commercial mission, sixth operational flight, and ninth mission overall. It also represents ISRO’s 101st launch and the agency’s fifth mission of the year.
Direct-to-mobile connectivity satellite
BlueBird Block-2 is part of a low-Earth-orbit satellite constellation designed to provide mobile connectivity directly to smartphones. It can support voice and video calls, text messaging, broadband data, and streaming on 4G and 5G networks, without requiring special antennas or satellite devices on the user’s phone.
The satellite carries a 223-square-metre phased-array antenna, the largest commercial communications antenna deployed in low-Earth orbit. Once deployed in space, it forms thousands of signal cells capable of picking up weak signals from standard smartphones.
Expanding coverage to remote areas
BlueBird Block-2 is engineered to provide connectivity in regions where terrestrial networks are limited, such as oceans, deserts, highlands, and disaster-affected zones.
Building global constellation
Earlier satellites in the BlueBird series were launched in 2024. The broader constellation will initially expand coverage across the United States and later to other regions. As more satellites are deployed, the system will hand over connections between spacecraft to ensure uninterrupted access when ground-based towers are unavailable.
