This follows the decision taken at the ESA Council meeting at Ministerial level in December 2014, to maintain Europe\u2019s leadership in the fast-changing commercial launch service market while responding to the needs of European institutional missions.<\/p>\n<p>This move is associated with a change in the governance of the European launcher sector, based on a sharing of responsibility, cost and risk by ESA and industry. The participating states are: Austria, Belgium, Czech Republic, France, Germany, Ireland, Italy, Netherlands, Norway, Romania, Spain, Sweden and Switzerland.<\/p>\n<p>The overarching aim of Ariane 6 is to provide guaranteed access to space for Europe at a competitive price without requiring public sector support for exploitation. Different concepts have been examined for Ariane 6 such as single- and dual-payloads, solid or cryogenic propulsion for the main stage, and the number of stages (three or more), all to cover a wide range of missions: GEO, either directly or through intermediate orbits, in particular GTO and LEO, Polar\/SSO, MEO or MTO.<\/p>\n<p\/>\n<p>The targeted payload performance of Ariane 6 is over 4.5 t for polar\/Sun-synchronous orbit missions at 800 km altitude and the injection of two first-generation Galileo satellites. Ariane 6 can loft a payload mass of 4.5\u201310.5 tonnes in equivalent geostationary transfer orbit.<\/p>\n<p>The exploitation cost of the Ariane 6 launch system is its key driver. Launch service costs will be halved, while maintaining reliability by reusing the trusted engines of Ariane 5. The first flight is scheduled for 2020.<\/p>\n<p>Ariane 6 has a \u2018PHH\u2019 configuration, indicating the sequence of stages: a first stage using strap-on boosters based on solid propulsion (P) and a second and third stage using cryogenic liquid oxygen and hydrogen propulsion (H).<\/p>\n<p>Ariane 6 provides a modular architecture using either two boosters (Ariane 62) or four boosters (Ariane 64), depending on the required performance. Two or four P120 solid-propellant boosters will be common with Vega C, an evolution of the current Vega launcher.<\/p>\n<p>The main stage containing liquid oxygen and hydrogen is based around the Vulcain 2 engine of Ariane 5.<\/p>\n<p>The upper stage of Ariane 6 builds on developments for the Adapted Ariane 5 ME, and cryogenic propulsion using the Vinci engine. It will be restartable and have direct deorbiting features to mitigate space debris.<\/p>\n<p>Flexibility is a design characteristic for A64 and A62. The launcher responds to different market needs by varying the number of boosters in the configuration.<\/p>\n<p>The A62, with two P120 solid boosters, will be used mainly in single-launch configurations, while the A64 \u2013 with four P120 solids \u2013 will enable double launch of medium-class satellites over 4.5\u20135 t, mainly for commercial market needs.<\/p>\n<p>The main characteristics of the Ariane 6 concept are: the total length of the vehicle is about 62 m; the cryogenic main stage holds about 150 t of propellants, the upper stage holds about 30 t; the external diameter of the cryogenic main stage and upper stages including the part that connects the fairing is about 5.4 m.&#8221;<\/p>\n<p>Video credit: ESA\/David Ducros<\/p>\n<p class=\"MsoNormal\" style=\"margin: 5px;\">&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>ESA and European industry are currently developing a new-generation launcher: Ariane 6.
