ISRO Chief Says 40-Storey Rocket In The Works To Lift 75 Tonnes To Orbit

The disclosure came with a pledge to roughly triple India’s satellite fleet within four years.

Overview

  • V. Narayanan told an Osmania University audience that ISRO is conceiving a launch vehicle capable of placing about 75,000 kg into low Earth orbit, describing it as roughly the height of a 40‑storey building.
  • India operates 55 satellites today, and Narayanan said the in‑orbit fleet will expand to about three times that number over the next three to four years.
  • Near‑term launches cited for this year include a NAVIC satellite, the new N1 rocket, a 6,500 kg U.S. communications satellite on an Indian launcher, the Technology Demonstration Satellite, and GSAT‑7R for the Indian Navy.
  • Media noted the absence of public government documents on the 75‑tonne concept and highlighted ISRO’s separate Next Generation Launch Vehicle, a roughly 90‑metre rocket designed for up to 30 tonnes to LEO and supported by a new Sriharikota launchpad targeted for 2029.
  • Narayanan pointed to human‑spaceflight preparations with an unmanned Gaganyaan mission planned soon, reaffirmed goals for a modular space station by 2035 and a Venus orbiter, and cited a recently detected rocket leak that prompted a launch postponement to ensure safety.
