Ariane-6’s core stage completes full 7 minute engine test
Engineers yesterday successfully completed a two-hour dress rehearsal countdown and fueling of an Ariane-6 first stage followed by a full seven minute engine burn, simulating what that stage would do during a launch.
The test took place on Ariane-6’s launchpad in French Guiana.
The November 23 test sequence was run the same way as the previous ones, with a launch sequence and final countdown representative of a launch, including removal of the mobile gantry and filling the launcher’s upper and core stage tanks with liquid hydrogen (-253° Celsius) and liquid oxygen (-183° Celsius). The test ended with the ignition of the core stage Vulcain 2.1 engine, followed by more than 7 minutes of stabilized operation covering the entire core stage flight phase. All functional aspects of Ariane 6’s core stage during the flight phase were tested.
According to the European Space Agency, only one more engine test of the Ariane-6’s upper stage remains before the spring launch can be attempted, and that engine test is planned for next month in Germany.
With the retirement of the Ariane-5 rocket in July, Europe has had no large rocket to launch payloads. Originally Ariane-6’s first launches were supposed to be in parallel with Ariane-5’s last launches, but its development is four years behind schedule.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

And with all this development and testing, they still refuse to embrace reusability. Is the ESA following NASA’s example of a major jobs program with a launch every so often?
