BlueBird-6 Satellite: ISRO to Launch Heaviest US Commercial Satellite on December 21

The Indian Space Research Organisation (ISRO) is set to achieve another historic milestone with the launch of BlueBird-6, the largest and heaviest US commercial satellite ever, on December 21, 2025. The mission, originally scheduled for December 15, was rescheduled due to extended pre-launch activities, including the integration of the LVM3 heavy-lift launch vehicle.

This ambitious mission highlights India’s growing stature as a global commercial launch service provider and marks a significant chapter in Indo-US space cooperation.

What is BlueBird-6?

BlueBird-6 is an advanced communication satellite developed by AST SpaceMobile, a US-based space technology company. It is designed to revolutionise global telecommunications by enabling direct-to-device broadband connectivity, especially in remote and underserved regions of the world.

With a massive weight of approximately 6.5 tonnes, BlueBird-6 will be launched from the Satish Dhawan Space Centre, Sriharikota, using ISRO’s proven LVM3 rocket.

Key Features of BlueBird-6 Satellite

World’s Largest Phased Array Antenna

• Covers nearly 2,400 square feet

• The largest antenna array ever deployed in space

• Enables high-capacity signal transmission

Direct-to-Device Connectivity

• Connects directly to standard mobile phones
