PSLV-C5

PSLV-C5 was the fifth operational launch and overall eighth mission of the Polar Satellite Launch Vehicle program. This launch was also the fifty-second launch by the Indian Space Research Organisation (IRSO) since its first mission on 1 January 1962. The vehicle carried and injected India's remote sensing satellite Resourcesat-1 (also known as IRS-P6) into a Sun-synchronous orbit; this was the heaviest and most sophisticated satellite built by IRSO through 2003. PSLV-C5 was launched at 04:52 hours Coordinated Universal Time (10:22 hours Indian Standard Time) on 17 October 2003 from Satish Dhawan Space Centre.^{[1][2][3][4][5][6][7]}

Payload

PSLV-C5 carried and deployed the ISRO's Resourcesat-1 (a.k.a. IRS-P6) into a sun-synchronous orbit. Resourcesat-1, which carried three cameras ("High Resolution Linear Imaging Self-Scanner", "Medium Resolution Linear Imaging Self-Scanner" and "Advanced Wide Field Sensor") was the tenth ISRO satellite in the IRS series and was intended not only to continue the remote sensing data services provided by IRS-1C and IRS-1D, but also to enhance the data quality. Although IRS-P6 had a design life of five years, the satellite was still operational as of October 2015.^{[1][2][9][10][11]}
