Thor 5, also known as Thor 2R, is a Norwegian communications satellite. It was successfully launched for Telenor atop an International Launch Services Proton-M/Briz-M carrier rocket, at 11:34 GMT on 11 February 2008.{{cite web | url = http://www.ilslaunch.com/ils/news-021108/ | title = ILS Proton successfully launches THOR 5 satellite | publisher = ILS | url-status = dead | archiveurl = https://web.archive.org/web/20080226105354/http://www.ilslaunch.com/ils/news-021108/ | archivedate = 2008-02-26 }} It is based on the STAR-2 satellite bus, and was constructed by Orbital Sciences Corporation. It carries 24 K_u band transponders, to provide direct-to-home television broadcasting. After launch, the Briz-M upper stage placed Thor 5 directly into a geosynchronous orbit, eliminating the need for orbital raising manoeuvres and making the spacecraft able to save weight by carrying less fuel. It is positioned at a longitude of 1° West.[http://space.skyrocket.de/doc_sdat/thor-5.htm Gunter's Space Page - Thor 5]
