On July 18, 1980, India launched its first satellite into orbit. This made India the seventh nation to launch an indigenously built satellite.
The Rohini RS-1 satellite lifted off from the Satish Dhawan Space Center at 8 a.m. local time. It was a small, experimental satellite weighing only about 77 lbs. (35 kilograms), and its primary purpose was to test out their new Satellite Launch Vehicle, or SLV-3 rocket.
This was a monumental mission for the Indian Space Research Organization, not just because they launched their own satellite, but also because they successfully launched the SLV-3 for the very first time.
