**Proton-M\/Nimiq 4\u00c2 \u2013 Live Update Pages**<\/em><\/p>\n **Click here for the Proton-M\/Nimiq 4 launch video** <\/em>\u2013 available NOW\u2026 Proton-M\/Nimiq 4 Overview:<\/em><\/p>\n The first three stages of the Proton will use a standard ascent trajectory to place the Breeze-M fourth stage and the Nimiq 4 satellite into a suborbital trajectory from which the Breeze M Upper Stage will then place itself and the spacecraft into a low Earth circular parking orbit.<\/p>\n Once Nimiq 4 is in the parking orbit, it will be injected into a geosynchronous transfer orbit following four additional burns of the Breeze M.<\/p>\n The first stage consists of a central tank containing the oxidizer surrounded by six outboard fuel tanks. Each fuel tank also carries one of the six RD-275 engines that provide first stage power. Total first stage sea-level thrust is approximately 9.6 MN (2,158,000 lbf) with a vacuum-rated level thrust of 10.5 MN (2,360,000 lbf).<\/p>\n The second stage is powered by three RD-0210 engines plus one RD-0211 engine and develops a vacuum thrust of 2.3 MN (517,000 lbf).<\/p>\n The third stage is powered by one RD-0213 engine, this stage develops thrust of 583 kN (131,000 lbf), and a four-nozzle vernier engine that produces thrust of 31 kN (7,000 lbf).<\/p>\n The Breeze M is powered by one pump fed gimbaled main engine that develops thrust of 19.6 kN (4,400 lbf). The Breeze-M is composed of a central core and a jettisonable additional propellant tank. Inert mass of the stage at lift-off is approximately 2,370 kg (5,225 lb).<\/p>\n The quantity of propellant carried is dependent on specific mission requirements and is varied to maximize mission performance. The Breeze M is controlled by a closed loop, triple-redundant guidance system.<\/p>\n The second payload has six beams covering Canada for such advanced services as high-definition television. Nimiq satellites are dedicated to the provision of direct-to-home services for Bell TV.<\/p>\n Nimiq 4 is a commercial communications satellite built by EADS Astrium. The main payload has 32 Ku-band channels providing specialty television and foreign language programming. The satellite will be located at 82 degrees West longitude.<\/p>\n Nimiq 4 is based on the Eurostar-3000S version of the highly successful Eurostar communications satellite. It will have a launch mass of 4.8 tonnes, a solar array span of 39 meters once deployed in orbit, and spacecraft power of 12 kW at end of life.<\/p>\n The double-floor E3000 model is equipped with an all-chemical propulsion system and Lithium-Ion batteries. The satellite, operating in geostationary orbit, will provide commercial services for a minimum of 15 years.<\/p>\n Re-live the launch updates on the live event pages, linked above.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":" International Launch Services (ILS) have launched their Proton M launch vehicle from Pad 39 (Area 200) at Baikonur Cosmodrome, Kazakhstan, carrying the Nimiq 4 satellite for Canada.
