Largest Communications Satellite Ever Built Launched Into Orbit
Paris, France (SPX) Aug 12, 2005 Today an Ariane 5G, a 'standard' version of the launcher, successfully launched into orbit the largest communications satellite ever built, Thaicom 4 (IPstar), weighing 6.5 tonnes. "With this successful launch, Ariane 5 has set a world record and once again proved its outstanding performance," said Evert Dudok, President of EADS SPACE Transportation. 'We can be proud of this success, which is the result of the great efforts made by all EADS-ST teams and industry partners,' said Hugues Laporte-Weywada, Director of Launchers at EADS SPACE Transportation. EADS SPACE Transportation has extensive expertise, unrivalled in Europe, as prime contractor for large-scale space programmes. Demonstrating its ability to lead a team of companies offering the wide range of skills and expertise required to design and develop complex projects such as Ariane 5, the company supplies all elements of the launch vehicle, including the stages, equipment bay and flight software, as well as numerous sub-assemblies. Ariane 5's solid-propellant boosters (EAPs) are manufactured and integrated by EADS SPACE Transportation at the launch site in French Guiana. The EAPs are ignited seven seconds after the main cryogenic stage (EPC) Vulcain engine and burn for about 130 seconds, delivering the main thrust at lift-off of up to 540 tonnes. EADS SPACE Transportation's Les Mureaux facility near Paris produces and integrates the EPCs. After jettison of the EAPs at an altitude of about 65 kilometres, the launcher's sole propulsion for a flight phase of 600 seconds is delivered by the Vulcain engine, providing a thrust of about 110 tonnes, the essential part of the impulse needed for insertion into orbit. The thrust chamber of the Vulcain engine was developed by EADS SPACE Transportation in Ottobrunn near Munich, and the necessary engine tests are also carried out in Germany, at Lampoldshausen near Heilbronn. EADS SPACE Transportation is Europe's centre of competence for the development and construction of Ariane upper stages at its sites in Bremen and Ottobrunn. The upper stage of Ariane 5 is designed to transport a payload to its target orbit following separation from the first stage, after which the upper stage is fully automatic and releases its payload on its way to geostationary orbit at an altitude of 36,000 kilometres. During today's mission, the Thaicom 4 (IPstar) satellite was inserted into transfer orbit at an altitude of 1,896 kilometres.
