Space activities in India started early in 1960s with the scientific investigation on upper atmosphere and ionosphere. Established in 1969, Indian Space Research Organisation (ISRO)  superseded the erstwhile Indian National Committee for Space Research (INCOSPAR). ISRO is headquartered at Bengaluru and is under the administrative control of the Department of Space, Government of India. Also Read - Inspiring!
