ISRO Developing Green Propulsion For Human Mission: Space Agency Chief

Indian Space Research Organisation Chairman K Sivan on Saturday said the space agency was developing “green propulsion” for its ambitious human space flight mission, ‘Gaganyaan’.

He also said it may be adopted for use in every stage of a rocket.

He was speaking at the 16th convocation of SRM Institute of Science and Technology.

Mr Sivan, also the Secretary, Department of Space, advised the new graduates to take up “calculated risk” in their life as it may safeguard them from “absolute failure”.

“As India continues to focus on economic growth, it needs to ensure that environmental damage is limited by adopting green technologies. ISRO has made space grade lithium-ion batteries and this technology is useful for mass adoption of electric vehicle”, he noted.

On the green propellant, Mr Sivan said, “Even in the rocket propulsion, ISRO is developing green propulsion for its human space flight mission. In future, all the propulsion stages may adopt green
propulsion,” he said.

According to ISRO, polar satellite launch vehicle (PSLV) a trusted workhorse of the space scientists — is a four-stage rocket filled with fuel which pushes the rocket to ensure that the satellite it carries is placed in the intended orbit.
