Developing green propulsion for human space mission 'Gaganyaan': ISRO
ISRO Chairman K Sivan said the space agency was developing "green propulsion" for its human space flight mission, 'Gaganyaan'. He also said it may be adopted for use in every stage of a rocket. Earlier, Sivan had said that Gaganyaan "will be delayed because of COVID-19". ISRO had previously planned to launch Gaganyaan by December 2021.
