It was indias first satellite.It was launched by the Soviet Union on 19 April 1975[1] from Kapustin Yar using a Kosmos-3M launch vehicle. It was built by the Indian Space Research Organisation (ISRO) The launch came from an agreement between India and the Soviet Union directed by U.R. Rao and signed in 1972. It allowed the USSR to use India ports for tracking ships and launching vessels in return for launching India satellites.[6] It was built to conduct experiments in X-ray astronomy, aeronomics, and solar physics. A power failure halted experiments after four days and 60 orbits with all signals from the spacecraft lost after five days of operation. According the Soviet media reports, the satellite continued to function and transmit information for some time. The satellite reentered the Earth's atmosphere on 11 February 1992.
bhaskara
The Bhaskara-I and II Satellites were two satellites built by the Indian Space Research Organisation that formed India's first low orbit Earth Observation Satellite. They collected data on telemetry, oce,anography and hydrology.
Bhaskara-I was launched on 7 June 1979 from Kapustin Yar aboard the Intercosmos launch vehicle. The satellite consisted of-
Two television cameras operating in visible (600 nanometre) and near-infrared (800 nanometre) and collected data related to hydrology, forestry and geology.
Satellite microwave radiometer (SAMIR) operating at 19 and 22 GHz for study of ocean-state, water vapour, liquid water content in the atmosphere, etc.
Bhaskara-II was launched on 20 november 1981from Volgograd launch station aboard aboard the Intercosmos launch vehicle. The satellite provided ocean and land surface data. One of two onboard cameras malfunctioned, however it sent back more than two
