PSLV-C6 was the sixth operational launch and overall ninth mission of the PSLV program. This launch was also the fifty-fourth launch by Indian Space Research Organisation since its first mission on 1 January 1962. The vehicle carried and injected India's two satellites; Cartosat-1 (a.k.a. IRS-P5) and HAMSAT into the Sun-synchronous orbit. PSLV-C6 was launched at 04:44 hours Coordinated Universal Time (10:14 hours Indian Standard Time) on 5 May 2005 from the second launch pad of the Satish Dhawan Space Centre.

Mission highlights Sixth operational launch of the PSLV program. Overall ninth mission of the PSLV program. Overall fifty-fourth launch by Indian Space Research Organisation. First flight to be launched from the second launch pad of Satish Dhawan Space Centre. Carried and injected two satellites built by ISRO.

Payload PSLV-C6 carried and deployed two Indian satellites, Cartosat-1 (a.k.a. IRS-P5) and HAMSAT into the Sun-synchronous orbit. Built by ISRO, Cartosat-1 was a stereoscopic remote sensing satellite and first of the Cartosat series of satellites. HAMSAT was a microsatellite, built for providing satellite based amateur radio satellite to the national as well as the international community of amateur radio operators (HAM).
