The significance of cryogenic propulsion systems in ISRO’s accomplishments with satellites and launch vehicles was discussed by Dr. V Narayanan in his first speech as ISRO chairman at the Physical Research Laboratory (PRL).
Narayanan highlighted three world records during the 101st Amrut Vyakhyaan that were established during the development of the cryogenic upper stage for the three-stage medium-lift launch vehicle LVM Mark-III.
For crewed missions under the Indian Human Spaceflight Program, the LVM Mark-III ROCKET is built to launch communication satellites into geostationary orbit.
Narayanan emphasized that ISRO broke the previous world record of 42 months by achieving a successful flight in just 28 months. Only three engines were used to achieve this: one for high-altitude testing, one for stage-level testing, and one for engine-level testing.The significance of cryogenic propulsion systems in ISRO’s accomplishments with satellites and launch vehicles was discussed by Dr. V Narayanan in his first speech as ISRO chairman at the Physical Research Laboratory (PRL).

Furthermore, ISRO achieved an unprecedented international record by finishing the rapid stage hot test for the C25 stage in just 34 days. The Gaganyaan Program, which entails creating human-rated propulsion systems and showcasing crew escape systems, including a test vehicle demonstration with a liquid engine, is one of the major accomplishments that Narayanan also highlighted.
“For human landing on Moon, at ISRO we are conceiving a vehicle with a lift-off mass of approximately 20 tonnes, three times that of the LVM Mark-III, with three stages each containing 500-750 tons of propellant,” stated Narayanan.
In order to eliminate the need to carry a lot of oxidizer, ISRO is also developing air-breathing propulsion technology that uses atmospheric air as an oxidizer. Low-cost space travel is made possible by this technology, which removes the need to
transport an oxidizer for combustion, which uses oxygen from the atmosphere to increase the payload fraction (the payload to lift-off mass ratio). Additionally, ISRO is working on rocket technologies that remove pollutants from the atmosphere.
On July 22, 2024, ISRO successfully completed the second experimental flight to demonstrate air breathing propulsion technology. An RH-560 sounding rocket with propulsion systems symmetrically mounted on either side was launched at 7 am from the Satish Dhawan Space Centre in Sriharikota for the test.
The sounding rocket performed satisfactorily during the flight test, and the air breathing propulsion systems were successfully ignited. The performance of the flight was evaluated by monitoring nearly 110 parameters, and the flight data will be helpful for the next
stage of these propulsion systems’ development. Several ground tests were conducted at different ISRO centers prior to the mission.
Additionally, in order to facilitate crewed missions to the Moon, ISRO intends to develop high thrust engines with a maximum of 300 tons, as opposed to the current maximum of 80 tons.
