BlueBird Block-2 Satellite Takes Flight on ISRO’s ‘Baahubali’ Rocket

Indian Space Research Organisation (ISRO) launches the BlueBird Block-2 communication satellite on December 24, 2025. The satellite will be carried by India’s most powerful rocket, the LVM3, also known as the ‘Baahubali’ rocket, from Sriharikota. This launch is being seen as a major milestone in global satellite-based mobile connectivity and India’s growing role in commercial space missions.

What Is the BlueBird Block-2 Satellite?

The BlueBird Block-2 is an advanced communication satellite developed by AST SpaceMobile, a United States based company. The satellite is designed to provide direct broadband connectivity to smartphones without the need for,

• Special satellite phones
• External antennas
• Hardware changes in mobile devices

This means ordinary smartphones will be able to make video calls, browse the internet, and use 4G/5G services from anywhere on Earth, including remote and rural areas.

Launch Vehicle: LVM-3 ‘Baahubali’ Rocket

The satellite will be launched using LVM-3, ISRO’s heavy-lift launch vehicle, popularly known as ‘Baahubali’ due to its massive lifting capability.

Key features of LVM-3,

• ISRO’s most powerful rocket
• Capable of carrying heavy and complex payloads
• Used earlier for Gaganyaan human spaceflight missions
• Suitable for commercial and deep-space missions

The LVM3-M6/BlueBird Block-2 Mission is the sixth operational flight of this rocket.
