ISRO’s Heaviest Launch: BlueBird Block-2

ISRO marked a major milestone by launching its heaviest satellite, BlueBird Block-2 (6,100 kg, by the US firm AST SpaceMobile), using the Launch Vehicle Mark-3 (LVM3) rocket, showcasing India’s strong heavy-lift launch capability.

  • The BlueBird Block-2, is the heaviest payload ISRO has placed into orbit, surpassing the previous record of 5,700 kg (OneWeb satellites).
  • The satellite was injected into a Low Earth Orbit (LEO) of approximately 520 km altitude.
  • It will provide direct-to-mobile connectivity, enabling 4G and 5G connectivity directly to mobile phones without requiring specialized ground stations.
  • This is ISRO’s 3rd commercial mission using LVM-3, following two OneWeb satellite launches in 2022 and 2023.
  • Despite global alternatives like SpaceX’s Falcon-9 and the ESA’s Ariane 6, the LVM-3 underscores ISRO’s capacity for heavy launches at much lower cost.
