Indian Space Research Organisation (ISRO) developing 40-storey rocket to launch 75-tonne satellite: Secretary, Department of Space, Chairman, Space Commission and Chairman, ISRO, Dr. V. Narayanan

India’s space ambitions are reaching unprecedented heights, with the Indian Space Research Organisation (ISRO) developing a rocket capable of lifting a staggering 75,000 kg into low Earth orbit, equivalent to the height of a 40-storey building, Secretary, Department of Space, Chairman, Space Commission and Chairman, ISRO, Dr. V. Narayanan, announced on Tuesday. Speaking at the convocation of Osmania University, he highlighted that this leap represents a massive advancement from the 17-tonne lift-off mass of the first Indian launcher built under Former President, Dr. APJ Abdul Kalam, which could carry only 35 kg into orbit. This new capability reflects India’s growing expertise in heavy lift launch vehicles and its ability to support large-scale satellite deployment for a variety of scientific, defence, and commercial purposes. 
He also outlined ISRO’s roadmap for 2025, which includes the launch of the Navigation with Indian Constellation (NAVIC) navigation satellite, the N1 rocket, and a 6,500 kg communication satellite for the United States (US), all using indigenous launch systems. Additionally, the agency plans to deploy the Technology Demonstration Satellite (TDS) and GSAT-7R, a dedicated military communication satellite for the Indian Navy, to replace the existing GSAT-7 (Rukmini). India currently maintains 55 satellites in orbit, a number expected to triple over the next three to four years, underlining the rapid expansion of its space infrastructure. His contributions to India’s space programme were recognised with an honorary Doctorate of Science, presented by the Governor of Telangana, Mr. Jishnu Dev Varma, further cementing his pivotal role in advancing India’s position in the global space arena.
