PSLV-C6was the sixth operational launch and overall ninth mission of thePSLVprogram. This launch was also the fifty-fourth launch byIndian Space Research Organisationsince its first mission on 1 January 1962. The vehicle carried and injected India's twosatellites;Cartosat-1(a.k.a. IRS-P5) andHAMSATinto 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 padof theSatish Dhawan Space Centre.[1][2][3][4][5]

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