'''PSLV-C6''' was the sixth operational launch and overall ninth mission of the [[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 [[satellite]]s; [[Cartosat-1]] (a.k.a. IRS-P5) and [[HAMSAT]] into the [[Sun-synchronous orbit]]. PSLV-C6 was launched at 04:44 hours [[Coordinated Universal Time]] (10:14 hours [[Indian Standard Time]]) on 5 May 2005 from the [[Satish Dhawan Space Centre Second Launch Pad|second launch pad]] of the [[Satish Dhawan Space Centre]].<ref name="PSLV series">{{cite news|title=PSLV series|publisher=astronautix.com|accessdate=28 August 2016|url=http://www.astronautix.com/p/pslv.html|archive-url=https://web.archive.org/web/20160820033519/http://astronautix.com/p/pslv.html|url-status=dead|archive-date=August 20, 2016}}</ref><ref name="PSLV-C6: A path-breaking launch">{{cite news|title=PSLV-C6: A path-breaking launch|publisher=[[Business Standard]]|accessdate=28 August 2016|url=http://www.business-standard.com/article/opinion/devangshu-datta-pslv-c6-a-path-breaking-launch-105051201010_1.html}}</ref><ref name="ISRO scientists meet Prime Minister">{{cite news|title=ISRO scientists meet Prime Minister|publisher=[[Indian Space Research Organisation]]|accessdate=28 August 2016|url=http://www.isro.gov.in/category-launchers/pslv-c6}}</ref><ref name="India's PSLV-C6 Successfully Launches 2 Satellites">{{cite news|title=India's PSLV-C6 Successfully Launches 2 Satellites|publisher=spaceref.com|accessdate=28 August 2016|url=http://www.spaceref.com/news/viewpr.html?pid=16830}}</ref><ref name="PSLV-C6 launched from Sriharikota">{{cite news|title=PSLV-C6 launched from Sriharikota|publisher=[[The Economic Times]]|accessdate=28 August 2016|url=http://articles.economictimes.indiatimes.com/2005-05-05/news/27496736_1_hamsat-launch-pad-cartosat-1}}</ref>
