ISRO’s LVM3-M6 Lifts 6.1-Tonne BlueBird Into Orbit, Setting India’s Heaviest Launch Record

The precise commercial mission for AST SpaceMobile underscores India’s growing credibility in heavy‑lift launch services.

Overview

  • Launched on December 24 from Sriharikota, the LVM3-M6 placed BlueBird Block-2 into a near-circular low Earth orbit at roughly 520 km with the required inclination, and ISRO declared the mission successful.
  • Weighing just over 6,100 kg, BlueBird Block-2 is the heaviest payload ever launched from India by an Indian rocket.
  • The satellite, developed by AST SpaceMobile, is part of a direct-to-device constellation designed to connect standard 4G and 5G smartphones from space.
  • The flight was conducted under a NewSpace India LimitedAST SpaceMobile commercial agreement and marked the third fully commercial mission for LVM3.
  • The demonstrated 6‑plus‑tonne lift strengthens India’s case for human spaceflight preparations and future station modules, following a year that mixed setbacks with successes such as SpaDeX, NISAR and an Indian visit to the ISS.
