Aryabhata

Aryabhata was India's first satellite, named after the great Indian astronomer of the same name.It was launched by the Soviet Union on 19 April 1975 from Kapustin Yar using a Cosmos-3M launch vehicle. It was built by the Indian Space Research Organization (ISRO) to gain experience in building and operating a satellite in space.
The 96.3 minute orbit had an apogee of 619 km and a perigee of 563 km, at an inclination of 50.7 degrees. It was built to conduct experiments in X-ray astronomy, aeronomics, and solar physics. The spacecraft was a 26-sided polygon 1.4 m in diameter. All faces (except the top and bottom) were covered with solar cells. A power failure halted experiments after 4 days in orbit. All signals from the spacecraft were lost after 5 days of operation. The satellite reentered the Earth's atmosphere on 11 February 1992. The satellite's image appeared on the reverse of Indian 2 rupee banknotes between 1976 and 1997 (Pick catalog and one rupee note number: P-79a-m).
