The mission duration will be 34 minutes and 37 seconds. The satellites will be launched for two major companies and long-standing Arianespace customers: the European Organization for the Exploitation of Meteorological Satellites EUMETSAT and the multinational satellite services and communication provider Intelsat. · The Meteosat Third Generation (MTG) system will help meteorologists meet one of their main challenges – the rapid detection and forecasting of severe weather events – so that timely warnings can be given to citizens, civil authorities and first responders. The data from MTG-I1 (I stands for Imager) will have a wide range of uses, from enabling aircraft to avoid storms and for earlier alerts of flooding, through to more precise monitoring of fires and fog. It will help to protect lives, property and infrastructure and bring economic benefits to Europe and Africa. The MTG satellites are developed and procured in cooperation with the European Space Agency by an industrial consortium led by Thales Alenia Space in cooperation with OHB. The satellites are developed according to the requirements defined by EUMETSAT after consultation with the users of its meteorological data. · Galaxy 35 and Galaxy 36 are the next satellites in Intelsat’s comprehensive Galaxy fleet refresh plan, a new generation of spacecraft that will provide Intelsat Media customers in North America with high-performance media distribution capabilities and unmatched penetration of cable headends. These two satellites will bring C-band contribution capacity to support high-profile events, such as collegiate and professional football, auto racing, baseball, golf, boxing and professional wrestling. The satellites also offer in-orbit protection for select customers in the broadcast arc serving North America. Ariane 5 is a European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It is launched from the Centre Spatial Guyanais in French Guiana. It has been used to deliver payloads into geostationary transfer orbit (GTO) or low Earth orbit (LEO). Ariane 5's cryogenic H173 main stage consists of a large tank 30.5 metres high with two compartments, one for liquid oxygen and one for liquid hydrogen, and a Vulcain 2 engine at the base with a vacuum thrust of 1,390 kN (310,000 lbf). Ariane 5 utilizes two solid boosters, each standing more than 30 meters tall with 237.8 metric tons of propellant. The boosters are ignited on the launch pad once the main cryogenic stage’s Vulcain engine has stabilized its thrust output. The Ariane 5 ECA launcher version utilizes the ESC-A cryogenic upper stage, which is powered by an HM7B engine. This reliable engine – which also served in the upper stage on Arianespace’s legendary Ariane 4 family of launchers – develops 67 kN maximum thrust in vacuum, and is turbopump-fed and regeneratively cooled. Its thrust chamber is fed by two pumps (liquid hydrogen and liquid oxygen) driven by a gas generator, a common turbine and a gearbox. #Ariane5 #ArianeSpace
