PSLV-C6

PSLV-C6 was the sixth operational launch and overall ninth mission of the Polar [Satellite Launch Vehicle|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 and HAMSAT into the Sun-synchronous orbit. PSLV-C6 was launched at 04:44 hours Coordinated Universal 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 Satish Dhawan [Space Centre Second Launch Pad|second launch pad] of Satish Dhawan Space Centre.
Carried and injected two satellites built by ISRO.

PSLV-C6 carried and deployed two Indian satellites, Cartosat-1 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.
