Green propulsion for India's first human space mission.

 K Sivan ( ISRO Chairman ) on Saturday said the space agency of India 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, near here. 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 '.

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, 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.

The Bengaluru-headquartered space agency had planned to launch its maiden human space flight mission 'Gaganyaan' by
December 2021.

But early this month, ISRO indicated that it is likely to be delayed by one year due to the impact of COVID-19 pandemic. Addressing students through virtual platform, the ISRO chief encouraged them to take up calculated risk as it would safeguard them from 'absolute failure.' 'You may fail, but each failure would provide a valuable
lesson. I can say with great confidence that India's space programme has been built on spectacular failures and each
failure has resulted in improvements in our system', he said.

'ISRO is very much open to you all. I request SRM to come forward with their innovative idea of making space activities as required by the Government of India. I am sure that SRM will do this work', he said. The Digital India initiative by the Centre was a key area to leverage and ISRO has already initiated reforms to make digital assets available easily to industry as well as for startups for making innovative applications in navigation, earth observation as well as disaster management, he said.
