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. [1] It is based on the STAR-2 satellite bus, and was constructed by Orbital Sciences Corporation. It carries 24 Ku 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. [2]

Norway Country in Northern Europe

Norway, officially the Kingdom of Norway, is a Nordic country in Northwestern Europe whose territory comprises of the western and northernmost portion of the Scandinavian Peninsula; the remote island of Jan Mayen and the archipelago of Svalbard are also part of the Kingdom of Norway. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land.

Communications satellite artificial satellite designed for telecommunications

A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. There are 2,134 communications satellites in Earth's orbit, used by both private and government organizations. Many are in geostationary orbit 22,236 miles (35,785 km) above the equator, so that the satellite appears stationary at the same point in the sky, so the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track it.

Telenor Multinational telecommunications company

Telenor ASA is a Norwegian multinational telecommunications company headquartered at Fornebu in Bærum, close to Oslo. It is one of the world's largest mobile telecommunications companies with operations worldwide, focus in Scandinavia, Eastern Europe and Asia. It has extensive broadband and TV distribution operations in four Nordic countries, and a 10-year-old research and business line for Machine-to-Machine technology. Telenor owns networks in 13 countries, and has operations in 29 countries.

Proton (rocket family) rocket family

Proton is an expendable launch system used for both commercial and Russian government space launches. The first Proton rocket was launched in 1965. Modern versions of the launch system are still in use as of 2019, making it one of the most successful heavy boosters in the history of spaceflight. All Protons are built at the Khrunichev State Research and Production Space Center factory in Moscow, transported to the Baikonur Cosmodrome, brought to the launch pad horizontally, and raised into vertical position for launch.

The Proton-M, (Протон-М) GRAU index 8K82M or 8K82KM, is an expendable Russian heavy-lift launch vehicle derived from the Soviet-developed Proton. It is built by Khrunichev, and launched from sites 81 and 200 at the Baikonur Cosmodrome in Kazakhstan. Commercial launches are marketed by International Launch Services (ILS), and generally use Site 200/39. The first Proton-M launch occurred on 7 April 2001.

AMC-14 is a communications satellite. Initially owned by SES Americom, AMC-14 was designed to be placed in geostationary orbit, following launch on a Proton rocket. Built by Lockheed Martin and based on the A2100 satellite bus, AMC-14 was to have been located at 61.5° west longitude for DISH Network service.
