History
In March 2007, shortly after the failure of a Sea Launch rocket launch in January 2007, Hughes Network Systems switched launch of Spaceway-3 from a Zenit-3SL rocket to an Ariane 5 launch vehicle.{{cite web|url=http://www.hughes.com/HUGHES/Doc/0/9CBP91UN8SDKN4FT1I7FT0LQ7A/03-01-07_Hughes_Signs_Contract_with_Arianespace_to_Launch_SPACEWAY_3.htm|title=Hughes Signs Contract with Arianespace to Launch SPACEWAY 3|date=March 1, 2007|publisher=Hughes|url-status=dead|archive-url=https://web.archive.org/web/20070303131748/http://www.hughes.com/HUGHES/Doc/0/9CBP91UN8SDKN4FT1I7FT0LQ7A/03-01-07_Hughes_Signs_Contract_with_Arianespace_to_Launch_SPACEWAY_3.htm|archive-date=March 3, 2007}}{{cite web|url=http://www.hns.com/HUGHES/Doc/0/O2TAOM5J20B4JD6PA9MMR5GS0B/12-08-05_HNS_SPACEWAY_Sea_Launch_award.htm|title=Hughes Network Systems Awards SPACEWAY 3 Launch Contract to Sea Launch Company|date=December 8, 2005|publisher=Hughes|url-status=dead|archive-url= https://web.archive.org/web/20070927012450/http://www.hns.com/HUGHES/Doc/0/O2TAOM5J20B4JD6PA9MMR5GS0B/12-08-05_HNS_SPACEWAY_Sea_Launch_award.htm|archive-date=September 27, 2007}}
Launch
Spaceway-3 was launched 14 August 2007 on an Ariane 5 launch vehicle with BSAT-3a.{{cite web|url=http://www.arianespace.com/site/news/releases/presrel07_08_14.html|title=Arianespace boosts SPACEWAY 3 and BSAT-3a into orbit|publisher=Arianespace|url-status=dead|archive-url=https://web.archive.org/web/20071019194734/http://www.arianespace.com/site/news/releases/presrel07_08_14.html|archive-date=2007-10-19}} It lifted off at 23:44 UTC from ELA-3 of the Centre Spatial Guyanais. Five hours and 46 minutes later, signals from the spacecraft were successfully received at a ground station in Hartebeesthoek, South Africa.{{cite web|url=http://www.boeing.com/ids/news/2007/q3/070815a_nr.html|title=Boeing-Built Spaceway 3 Satellite Operational after Successful Launch|publisher=Boeing Integrated Defense Systems|url-status=dead|archive-url=https://web.archive.org/web/20080411171552/http://www.boeing.com/ids/news/2007/q3/070815a_nr.html|archive-date=2008-04-11}}
