Europe's next rocket, Ariane 6, passed all its qualification tests in preparation for its first flight, and the full-scale test model has been removed from the launch pad to make way for the real rocket that will ascend to space.
The test model at Europe's Spaceport in Kourou, French Guiana, stood 62 m high. It is exactly the same as the "production model" Ariane 6 rockets that will soon be launched, except that its boosters do not need to be tested as part of the complete rocket, so the boosters are not fueled.
Teams preparing Ariane 6 for its inaugural flight successfully completed for the first time a launcher preparation and countdown sequence, on 18 July. Representatives of ESA, Ariane 6 prime contractor ArianeGroup and launch base prime contractor and test conductor CNES completed important objectives for system qualification and performed a series of actions fully representative of a launch chronology.
The launch simulation included the removal of the mobile gantry, the chill-down of ground and launcher fluidic systems, the filling of the upper and core stage tanks with liquid hydrogen (–253°C) and liquid oxygen (–183°C), and at the end of the test, the successful completion of a launch chronology up to the ignition of the Vulcain 2.1 engine thrust chamber by the ground system.
NASA achieves milestone for engines to power future Artemis missions

![The second – and final – RS-25 certification test series begins Oct. 17, 2023. When the liquid hydrogen and liquid oxygen propellants mix and ignite, an extremely high temperature exhaust, of up to 6,000-degrees Fahrenheit, mixes with water to form steam that exits the flame deflector and rises into the atmosphere, forming a cloud that subsequently cools.

NASA achieved a major milestone April 3 for production of new RS-25 engines to help power its Artemis campaign to the moon and beyond with completion of a critical engine certification test series at NASA's Stennis Space Center near Bay St.
