LVM3-M6 / BlueBird Block-2 Mission | Live Launch | ISRO-NSIL

Why It Matters

By delivering the heaviest LVM3 payload and enabling direct‑to‑smartphone 5G broadband, the launch cements ISRO’s role in the global commercial space market and accelerates worldwide mobile connectivity.

Key Takeaways

• LVM3 M6 lifts 6,100‑kg Bluebird Block 2 satellite into orbit
• Heaviest payload ever launched on India's LVM3 rocket
• Satellite will provide 4G/5G connectivity directly to smartphones
• Launch scheduled Dec 24, 2025, 08:55:30 IST from Satish Dhawan
• Mission showcases ISRO's growing commercial launch capabilities and reliability

Summary

The video documents the live launch of ISRO’s LVM3‑M6 vehicle, tasked with delivering the Bluebird Block 2 communications satellite for AS Space Mobile, a U.S. firm. The launch took place on 24 December 2025 at 08:55:30 IST from the second pad at Satish Dhawan Space Centre, marking the ninth flight of the LVM3 heavy‑lift launcher.

The mission carried a 6,100 kg payload—the heaviest ever placed on an LVM3—targeting a 520 km circular orbit at 53° inclination. Detailed rollout footage highlighted the integration of two S200 solid strap‑on boosters, the L110 liquid core stage, and the C25 cryogenic upper stage, as well as the satellite’s encapsulation and payload fairing procedures. The launch sequence proceeded nominally, with solid booster ignition, staged separations, and a 12‑minute‑20‑second cryogenic burn delivering a delta‑V of 3.9 km/s.

ISRO officials emphasized the satellite’s role in a global low‑Earth‑orbit constellation designed to bring 4G and 5G services directly to standard mobile phones, eliminating the need for ground infrastructure. The Bluebird Block 2 carries a 223 m² phased‑array antenna, making it one of the largest commercial communications payloads in LEO. The commentary also referenced ISRO’s track record of over 400 foreign satellite launches and its strategic push under Prime Minister Narendra Modi’s space reforms.

The successful deployment underscores India’s emergence as a reliable provider of heavy‑lift commercial launches, expanding market share in the burgeoning satellite‑based broadband sector. For telecom operators, the mission promises near‑global coverage and low‑latency connectivity, potentially reshaping mobile data delivery and accelerating the rollout of next‑generation services worldwide.

Original Description

Watch the LVM3-M6 / BlueBird Block-2 mission live, conducted by ISRO-NSIL, deploying the BlueBird Block-2 communication satellite of AST SpaceMobile into Low Earth Orbit.

🚀 Launch: 24 December | 08:54 IST

📡 Livestream: 24 December | 08:24 IST onwards

This mission marks the 6th operational flight of the LVM3 launch vehicle. LVM3-M6 will place the BlueBird Block-2 satellite into Low Earth Orbit, and it is the largest commercial communications satellite to be deployed in Low Earth Orbit as well as the heaviest payload to be launched by LVM3 from Indian soil.
