Vikram-S, India's first privately developed rocket, will be launched by the Indian Space Research Organisation (ISRO) from its spaceport in Sriharikota, about 115 kms from Chennai, at 11:30 am today. Built by Skyroot Aerospace, a start-up based in Hyderabad, the rocket launch would be over in less than two minutes touching a lesser altitude of 81.5 k. NDTV's Sam Daniel spoke to Dr Pawan Goenka, the Chairman of Indian National Space Promotion and Authorisation Centre, INSPACE, who calls this as a major milestone.
