PICTURE OF ARYABHATA

Aryabhata was India's first satellite, named after a ancient Indian mathematician. It was launched by the Russians on 19 April 1975 from Kapustin Yar. Aryabhata was built by the Indian Space Research Organization (ISRO) 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 Aryabhata satellite mission had three main objectives:

• First was to evolve the methodology of conducting a series of complex operations on a satellite while it is in orbit.

• The second mission objective was to set up ground based receiving, transmitting, and tracking systems and

• The final objective was to establish infrastructure for the fabrication of spacecraft systems. In essence the mission was to test the ability of India to successfully build and launch a spacecraft and develop key tracking and fabrication technologies for the creation of future spacecraft.

• The Aryabhatta satellite also carried a scientific payload of instruments. They included Doppler radar, interferometry, and tone ranging systems for satellite tracking purposes. It also carried instruments for X-ray astronomy, neutron and gamma ray detectors, as well as experiments for voice transmission, and weather data. .

HERE, THE SATELLITE IS TILTED 90 DEGREE LEFT.

HERE THE SATELLITE IS TILTED 180 DEGREE.

HERE THE SATELLITE IS TILTED 90 DEGREE RIGHT.

• IN ALL THE ABOVE THREE CASES, ATTEMPT WAS MADE TO TILT THE SATELLITE 45 DEGREES, BUT THE SATELLITE COULD NOT STAND ON THE SINGLE EDGE DUE TO ITS HEAVY WEIGHT. HENCE, THE TILTING HAS BEEN DONE 90 DEGREE FOR CONVENIENCE.

• THANKING ONE AND ALL.
