The Chairman of Indian Space Research Organisation (ISRO), K Sivan has highlighted that the space agency is developing green propulsion technology for its Human Space Flight Mission, Gaganyaan. He pointed out this at the 16th convocation of SRM Institute of Science and Technology.
Green propulsion may be used in each stage of a rocket.
ISRO started developing Green Propulsion Technology in the year 2018. The agency developed Ammonium Di-Nitramide as an oxidizer and a solid propellant Glycidyl Azide polymer as fuel.
As per the agency, PSLV i.e. polar satellite launch vehicle is a 4-stage rocket filled with fuel that pushes the rocket ensuring that the satellite carried by it is placed in the correct orbit.
GSLV i.e. geo-stationery launch vehicle (GSLV) is a 3-stage rocket with a cryogenic upper stage.
K Sivan also highlighted that after the reforms in the space sector by the central government, the participation of non-governmental agencies in space activities will increase.
It is a human spaceflight mission of India originally intended to be launched by December 2021 but now the mission has been delayed due to COVID-19 and will be launched in 2022. The crewed spacecraft under the mission is being designed so as to carry three people.
It is the space research agency of India headquartered in Bengaluru, Karnataka. It was established in the year 1969.
