On May 5, the Indian Space Research Organization (ISRO) conducted its 12th consecutive successful rocket launch, of the Polar Satellite Launch Vehicle (PSLV), which carried the 1.6 ton CartoSat-1 and the 40kg HAMSat, both locally built. Cartosat is a cartographic mapping satellite with a unique capability to generate 3D maps of the earth's surface. It joins the rest of the Indian Remote Sensing (IRS) satellites aloft, which constitutes the world's largest non-military remote sensing satellite cluster. HAMsat is a HAM
radio communication satellite.
The PSLV-C6 mission was the third instance of multiple satellites being injected by a PSLV, after the C2
mission (IRS-P4, TUBSat from Tech Univ of Berlin and KITSat from Korea Inst of Technology) and the C3
missions (TES military surveillance sat, the German BIRD and Belgian PROBA satellites).
The PSLV is a 44.5m 295ton launcher with a capability of upto 4 tons to LEO and 1.3 tons to SSO/GTO (SSO payload restricted due to flight path complexity). All missions are conducted from the Satish Dhawan Space center, which has two launch pads, one capable of PSLV/GSLV and the other a universal VAB/launch pad.
