&amp;#039;&amp;#039;&amp;#039;INSAT-4C&amp;#039;&amp;#039;&amp;#039; was an [[India]]n [[communications satellite]] which was lost in a launch failure in 2006. Had it reached orbit, it would have formed part of the [[Indian National Satellite System]]. Launched in 2007, it was intended to have operated in [[geostationary orbit]] at a longitude of 73.97°&amp;amp;nbsp;east. The [[INSAT-4CR]] satellite, launched in September 2007, replaced it.&amp;lt;ref name=&amp;quot;UCS&amp;quot;&amp;gt;{{cite web|url=http://www.ucsusa.org/assets/documents/nwgs/UCS_Satellite_Database_9-1-13.txt|title=UCS Satellite Database|publisher=Union of Concerned Scientists|date=1 September 2013|access-date=12 November 2013}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Built by the [[Indian Space Research Organisation]], INSAT-4C was based upon the [[I-2K]] [[satellite bus]]. It had a dry mass of {{convert|950|kg}}, or {{convert|2168|kg}} when fully fuelled. It was expected to have operated for ten years. The satellite carried twelve [[Ku band]] transponders, with two [[solar array]]s to generate power.&amp;lt;ref name=&amp;quot;gsp&amp;quot;&amp;gt;{{cite web|url=http://space.skyrocket.de/doc_sdat/insat-4a.htm|title=Insat 4A, 4B|first=Gunter|last=Krebs|work=Gunter&amp;#039;s Space Page|access-date=12 November 2013}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
ISRO launched INSAT-4C on the second operational flight of the [[Geosynchronous Satellite Launch Vehicle]], which was flying in the Mk.I configuration. The launch took place from the [[Satish Dhawan Space Centre Second Launch Pad|Second Launch Pad]] at the [[Satish Dhawan Space Centre]]; the first time the pad was used by a GSLV.&amp;lt;ref&amp;gt;{{cite web|url=http://www.nasaspaceflight.com/2006/07/indias-insat-4c-launch-vehicle-explodes/|title=India&amp;#039;s Insat 4C launch – vehicle explodes|first=Chris|last=Bergin|publisher=NASASpaceflight.com|date=10 July 2006|access-date=12 November 2013}}&amp;lt;/ref&amp;gt; Liftoff occurred at 12:08 UTC on 10 July 2006.&amp;lt;ref name=&amp;quot;launchlog&amp;quot;/&amp;gt; Early in the flight a [[thrust controller]] in one of the four liquid rocket boosters failed,&amp;lt;ref name=&amp;quot;slr&amp;quot;&amp;gt;{{cite web|url=http://www.spacelaunchreport.com/gslv.html|title=GSLV|first=Ed|last=Kyle|work=Space Launch Report|access-date=12 November 2013}}&amp;lt;/ref&amp;gt; resulting in the booster cutting off shortly afterwards.&amp;lt;ref&amp;gt;{{cite web|url=http://spaceflightnow.com/news/n0607/10gslvfailure/|title=Indian rocket launch ends in failure soon after liftoff|first=Stephen|last=Clark|publisher=Spaceflight Now|date=10 July 2006|access-date=12 November 2013}}&amp;lt;/ref&amp;gt; Approximately 55 seconds after launch&amp;lt;ref&amp;gt;{{cite web|url=http://www.spaceflightnow.com/news/n0709/02insat4cr/|title=India&amp;#039;s large satellite launcher returns to flight|first=Stephen|last=Clark|publisher=Spaceflight Now|date=2 September 2007|access-date=12 November 2013}}&amp;lt;/ref&amp;gt; the vehicle veered off-course and began to disintegrate.&amp;lt;ref&amp;gt;{{cite web|url=http://news.bbc.co.uk/1/hi/world/south_asia/5165470.stm|title=Key Indian satellite launch fails|publisher=BBC News|date=10 July 2006|access-date=12 November 2013}}&amp;lt;/ref&amp;gt; The [[range safety officer]] subsequently commanded the remainder of the rocket to self-destruct.&lt;br /&gt;
