6. Aryabhata was a 26 sided polyhedron satellite. Except for the top and bottom parts, the whole sides were covered by solar panels to maintain the power supply intact.
7. After the launch during its first 96.46 minutes in orbit, the perigee was 563 kilometers and it had an apogee of 619 kilometers.
8. During its orbit, the inclination towards the Earth was 50.7 degrees.
9. But Alas! The Aryabhata worked for only 4 days. After completing 60 orbits a major power failure detected and on its fifth day, all connection was broken.
10. Although its mainframe was kept working until march 1981.
