India reached a major space milestone just before the end of 2025. On December 24, the Indian Space Research Organisation (ISRO) successfully launched its heaviest satellite ever from Indian soil. The satellite, named BlueBird Block-2, is also known as BlueBird 6.
The launch took place using ISRO’s powerful LVM3-M6 rocket. This rocket is widely called “Baahubali” because of its strength and heavy-lift capacity. With this mission, ISRO once again proved its ability to handle large and complex space projects.
The BlueBird satellite weighs about 6,100 kilograms, which is more than six tons. This makes it the heaviest payload ever launched from India. The satellite was sent into space smoothly and placed into a circular Low Earth Orbit at an altitude of around 520 kilometers above Earth.
This mission was a commercial project. The satellite belongs to AST SpaceMobile, a company based in the United States. The main goal of the mission is to improve global communication. BlueBird Block-2 is designed to provide direct 4G and 5G broadband connectivity to smartphones, even in remote and hard-to-reach areas.
This means people may one day use regular mobile phones for fast internet without needing towers nearby. The technology could help communities in rural regions, deserts, oceans, and disaster-hit areas stay connected.
ISRO officials confirmed that the satellite was placed in orbit successfully and all mission objectives were achieved. The smooth launch showed the reliability of India’s heavy-lift rocket and its growing role in the global space market.
This achievement is another proud moment for India’s space program. It highlights ISRO’s rising strength in commercial space launches and advanced satellite missions. With missions like this, India continues to move forward as a trusted and capable space power.
