About : 

  • The launching of India’s first satellite ‘Aryabhata‘, named after the famous Indian astronomer and mathematician of the fifth century is a historic occasion and a milestone in India‘s space research programme.
  • The diamond-shaped satellite has been designed and built by the Indian Space Research Organisation (ISRO) at its Indian Scientific Satellite Project in Bangalore. This 26-faced blue and violet spacecraft is 147 cms. in diameter and 116 cms. high.
  • The satellite has been launched from a Soviet cosmodrome. Its orbit is 500 kms. above the earth circling it once in every 90 minutes. The satellite carries instruments to conduct experiments on X-ray astronomy, solar neutron and Gamma rays, and aeronomy. The data obtained from these three experiments brought in new information on outer space, the sun and the earth’s atmosphere.
  • The data collected from the experiments are temporarily stored in tape-recorders on board and are transmitted in code to the ground receiving stations located at ISRO’s Sriharikota Range and a similar one near Moscow everytime the satellite passes over these stations.
