PSLV-C5
PSLV-C5 was the fifth operational launch and overall eighth mission of the Polar Satellite Launch Vehicle program. This launch was also the fifty-second launch by the Indian Space Research Organisation since its first mission on 1 January 1962. The vehicle carried and injected India's remote sensing satellite Resourcesat-1 into a sun-synchronous orbit; this was the heaviest and most sophisticated satellite built by IRSO through 2003. PSLV-C5 was launched at 04:52 hours Coordinated Universal Time on 17 October 2003 from Satish Dhawan Space Centre.
