PSLV-C6 was the sixth operational launch and overall ninth mission of thePSLV program. This launch was also the fifty-fourth launch byIndian Space Research Organisation since its first mission on 1 January 1962. The vehicle carried and injected India's twosatellites;Cartosat-1 (a.k.a. IRS-P5) andHAMSAT into theSun-synchronous orbit. PSLV-C6 was launched at 04:44 hoursCoordinated Universal Time (10:14 hoursIndian Standard Time) on 5 May 2005 from thesecond launch pad of theSatish Dhawan Space Centre.^{[1][2][3][4][5]}

PSLV-C6 carried and deployed two Indian satellites,Cartosat-1 (a.k.a. IRS-P5) andHAMSAT into theSun-synchronous orbit. Built byISRO, Cartosat-1 was a stereoscopicremote sensing satellite and first of theCartosat series of satellites.^[5] HAMSAT was amicrosatellite, built for providing satellite basedamateur radio satellite to the national as well as the international community ofamateur radio operators (HAM).^[10]
