ISRO Develop Next Generation Launch Vehicle Payloads Capacity 10 Tonnes to GTO

Space News ,India :- Success always pushes us to achieve more, and the Indian Space Research Organisation (ISRO) is a perfect example of this. ISRO has increased the payload capacity of its heavy rocket GSLV from 1,500 kg to 2,274 kg and aims to launch even heavier satellites into the Geosynchronous Transfer Orbit (GTO).

ISRO is now on a mission to develop a next-gen rocket in collaboration with private industries, capable of carrying payloads up to 10 tonnes. Inspired by the success of the GSLV-F14/INSAT-3DS mission, which launched one of the heaviest payloads into GTO, ISRO is now targeting greater heights by launching satellites with a ten-tonne capacity.

The project report for the development of this next-generation rocket is ready, and ISRO is seeking government funds to enhance its capabilities in the competitive space sector. According to ISRO Chairman S. Somanath, the team has submitted the project report along with estimated costs, and the next step involves approaching the government for funds and establishing mechanisms for development, including private industry participation.

The new rocket design is in progress and will be partially reusable, with a capacity of about 10 tonnes into GTO. Currently, ISRO's heaviest rocket, LVM3 (formerly GSLV-MkIII), can carry satellites up to four tonnes. The next-gen rocket will naturally be heavier to accommodate higher payloads.

Mr. Somanath also provided updates on India's first manned mission, Gaganyaan, scheduled for 2025. Two more abort missions are planned this year following the success of the first unmanned flight test (TV-D1) last year, demonstrating the crew escape system. Various tests and activities are set for 2024 to realize the manned space mission in 2025.

Additionally, ISRO is planning its next moon mission, Chandrayaan-4, with the goal of achieving something unprecedented—possibly bringing a lunar sample back using a robot. High-end technology and government funding are essential for this ambitious project.

Regarding the Indo-US collaboration on the earth observation satellite NASA-ISRO Synthetic Aperture Radar (NISAR), Mr. Somanath clarified that it is intended solely for earth observation, emphasizing a focus on the Earth as a system, not for surveillance.
