Detailed Solution
ISRO's historic 100th space mission was accomplished on 9 September 2012 from the Satish Dhawan Space Centre (SDSC-SHAR), Sriharikota.
The mission used PSLV-C21. It was the 22nd flight of the PSLV, and the launch took place from the First Launch Pad at Sriharikota.
PSLV-C21 carried two foreign satellites—
SPOT-6 — a French Earth Observation Satellite
PROITERES — a Japanese micro-satellite
SPOT-6 had a lift-off mass of about 712 kg, while PROITERES weighed about 15 kg. Both satellites were placed in an approximately 655 km polar orbit.
Mahendragiri is primarily associated with propulsion-system testing infrastructure, while Thumba is famous for sounding-rocket activities. The launch site of this particular mission was Sriharikota.
