Aryabhata is the first Indian satellite
built by India. It was named after Aryabhata I
, the prominent ancient Indian astronomer
of the 5th century AD. The satellite was assembled at Peenya, near Bengaluru
but was launched from the erstwhile Soviet Union by a Russian-made rocket on April 19, 1975. The 96.3 minute orbit had an apogee of 619 km and a perigee of 563 km, at an inclination of 50.7 degrees.
Naming of Aryabhata
The satellite was named after the Indian mathematician-astronomer Aryabhata (476-550 AD). The 5th Century Indian mathematician and astronomer is best known for explaining the phenomenon of lunar and solar eclipses and for calculating the value of Pi correct to 4 decimal places.
Structure of Aryabhata
Aryabhata weighed 360 kg. The spacecraft was a 26-sided polygon 1.4 m in diameter. All faces (except the top and bottom) were covered with solar cells which generated electricity for the satellite's 46W power supply system. A power failure halted experiments after 4 days in orbit. All signals from the spacecraft were lost after 5 days of operation. The satellite re-entered the Earths atmosphere on 11 February 1992.
Purpose of Aryabhata
Aryabhata was built by the Indian Space Research Organization
(ISRO) to conduct experiments in X-ray astronomy, aeronomics and solar physics. It was instrumented to explore conditions in the Earths ionosphere, measure neutrons and gamma rays from the Sun
and perform investigations in X-ray astronomy
. The scientific instruments had to be switched off during the 5th day in orbit because of a failure in the satellites electrical power system. Useful information nevertheless was collected during the five days of its operation.
