Launch
It was launched by the Soviet Union on 19 April 1975 from Kapustin Yar using a Kosmos-3M launch vehicle. It was built by the Indian Space Research Organisation (ISRO) to gain experience in building and operating a satellite in space. 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.
On 19 April 1975 the satellite’s 96.46-minute orbit had an apogee of 611 kilometres (380 mi) and a perigee of 568 kilometres (353 mi), at an inclination of 50.6 degrees. It was built to conduct experiments in X-ray astronomy, aeronomics, and solar physics. The spacecraft was a 26-sided polyhedron 1.4 metres (4.6 ft) in diameter. All faces (except the top and bottom) were covered with solar cells. 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.
