\t\t\t\t\t\t04\/07\/2024<\/span> Ariane 6 is scheduled to launch on 9 July 2024, with a launch window from 15:00-19:00 local time at Europe\u2019s Spaceport in French Guiana (19:00\u201323:00 BST, 9 July 20:00\u201310 July 00:00 CEST).<\/p>\n<\/p><\/div>\n This is a big moment for Europe, as the rocket will ensure our guaranteed, autonomous access to space \u2013 and all of the science, Earth observation, technology development and commercial possibilities that entails. With many features brand new to Ariane 6, we\u2019ll be able to carry more and take it further, while responsibly disposing of the launcher.<\/p>\n Watch the entire launch live on ESAWebTV, starting half an hour before liftoff. The transmission is available in English with commentary by Katy Haswell and ESA Ariane 6 launch system architect engineer Tina B\u00fcchner da Costa. French commentary is provided by Lise Pederson and ESA\u2019s head of Infrastructure and value chain for Space Transportation Luce Fabreguettes. A German live translation is available here.<\/p>\n<\/p><\/div>\n The first flight of Ariane 6 will have three phases, each of which will demonstrate various abilities for Europe\u2019s newest heavy-lift rocket.<\/p>\n<\/p><\/div>\n The first phase of Ariane 6\u2019s flight, events one to five in the infographic above, will launch the rocket off Earth and into space. The thrust will come from the main stage engine, Vulcain 2.1, together with the force from two powerful P120C boosters. Phase 1 will also include the separation of the main stage from the upper stage, and the first boost of the upper stage\u2019s Vinci engine which inserts it, and its passengers, into an elliptical orbit 300 by 700 km above Earth.<\/p>\n The Vinci engine will fire until about 18 minutes after liftoff, after which point Ariane 6 will have demonstrated that it can match a typical flight profile of its predecessor, the Ariane 5 ECA version.<\/p>\n<\/p><\/div>\n The next phase (events six to nine above) is when Ariane 6\u2019s newest feature is put to the test: reignition of the upper stage. In Phase 2, the Vinci engine will re-fire for the first time, changing Ariane 6\u2019s orbit from elliptical to a circular orbit 580 km from Earth\u2019s surface.<\/p>\n Re-igniting an engine in zero gravity may not sound so difficult, but as fuels float freely inside the tanks, its not as simple as you might think. The Auxiliary Propulsion Unit (APU) helps here, providing a small but steady amount of thrust to cause fuel in the Vinci tanks to settle ensuring it can fire again.<\/p>\n<\/p><\/div>\n The first re-ignition will be followed by the deployment of Ariane 6\u2019s first three satellites; OOV-Cube, Curium One and Robusta-3A, and the activation of two of its onboard experiments, YPSat and Peregrinus.<\/p>\n A few seconds later, the second batch of satellites will deploy; 3Cat-4, ISTSat and GRBBeta, and the last two experiments will be turned on, SIDLOC and Parisat. A third separation command will then deploy CURIE and replicator.<\/p>\n At this point, Ariane 6 has done its job, reigniting \u00a0its upper stage and deploying its eight satellite missions and activating all onboard experiments.<\/p>\n<\/p><\/div>\n The final phase in Ariane 6\u2019s inaugural flight (events nine to 12 above) will push the cryogenic upper stage even further to its limit, and validate its ability to really perform under microgravity conditions.<\/p>\n The final boost for the upper stage will require it to re-ignite after its longest period \u201coff\u201d in space, initiating its controlled deorbit back through Earth\u2019s atmosphere over the \u2018NEMO point\u2019 in the South Pacific.<\/p>\n Moments later, the two reentry capsules onboard will separate from the upper stage to make their descent to Earth with the aim to survive their fiery re-entry through our atmosphere.<\/p>\n A final command will be sent to passivate the upper stage \u2013 removing any energy on board to prevent possible explosions, another vital step for a sustainable decent \u2013 before it burns up in the atmosphere. Ariane 6 was designed to have this ability \u2013 to prevent the upper stage from lingering in space as space debris.<\/p>\n<\/p><\/div>\n For all these moments and more, including interviews with key players in the development of the rocket, insights into its fascinating and varied payloads, and what this moment means, watch the launch livestream on\u00a0ESAWebTV.<\/p>\n The launch will be covered in several languages which can be followed at the links below:<\/p>\n English: https:\/\/youtube.com\/live\/B0oFpOJaIYc?feature=share<\/p>\n French: https:\/\/youtube.com\/live\/AfNPzSOalEU?feature=share<\/p>\n German: https:\/\/youtube.com\/live\/a_87OnvB_fQ?feature=share<\/p>\n A clean feed without commentary is availble too:\u00a0https:\/\/youtube.com\/live\/ogXamYYJpQk?feature=share<\/p>\n Get into the mood with some Ariane 6 apparel from the\u00a0ESA Space Shop.<\/p>\n<\/p><\/div>\n
