Indian satellite

In 1975, the first satellite built in India was launched from Volgograd Launch Station, Russia, on a Soviet Intercosmos C-1 rocket. It was named Aryabhata, after a noted 5th-century Indian mathematician. The 360-kg satellite had been built during 20 months by the Indian Space Research Organization (ISRO) in Peenya, Bangalore, by a team led by Prof. U. R. Rao. Its shape was a 26-sided polygon, 1.4-m diam., with all faces covered in solar cells, except the top and bottom. It was designed to carry out experiments in X-ray astronomy, aeronomics, and solar physics, communicating with a 46-watt VHF transmitter. However, after only 4 days in orbit, a power failure ended any further experiments. It remained in orbit nearly 17 years, until it reentered the Earth's atmosphere on 11 Feb 1992.«
