The European Space Agency ( ESA ) has successfully conducted a full - scale rehearsal of its new Ariane 6 Eruca sativa at Europe ’s Spaceport in French Guiana , marking a significant whole tone towards the launch vehicle ’s first flight .
Ground comptroller performed the full - musical scale sozzled attire rehearsal on Thursday , November 23 , agree to an ESApress release . The use ( carried out at Europe ’s Spaceport in French Guiana ) involve a complete launching countdown and a seven - minute firing of the core microscope stage ’s Vulcain 2.1 engine . This rehearsal mirrors the rocket ’s functioning during an existent space launch .
The mental test saw the Ariane 6 ’s core phase engine burn through nearly 150 metric tons of propellant , incorporate supercooled fluid oxygen and liquid hydrogen . The Vulcain 2.1 engine , an modern version of the Vulcain 2 that powered the recently put out Ariane 5 rocket , have a simplify , cost - efficacious design with technological improvements in the nozzle and ignition system organisation , ESA explained .

The test encompass not only the kernel microscope stage but also the launch pad and operational aspects , include fueling the main and orbital stages and evaluating the thermal impact on mechanical and electrical portion during launching .
“ The teams from ArianeGroup , CNES and ESA have now run through every step of the rocket ’s flight without it pass on Earth , ” said ESA ’s Director General Josef Aschbacher in the military press vent . “ This milepost rehearsal comes after years of designing , provision , prepare , construction and toilsome work from some of the finest space engineer in Europe . We are back on trail towards resecuring Europe ’s autonomous access to place . ”
Theexpendable Ariane 6 rocket , with its two variants , Ariane 62 and Ariane 64 , is integral to Europe ’s succeeding space plan . The Ariane 62 , equipped with two solid rocket engine boosters , is tailor for government and scientific missions and equal to ofdeliveringup to 4.5 metrical tons to Geostationary Transfer Orbit ( GTO ) and 10 metric lots to Low Earth Orbit ( LEO ) . The more robust Ariane 64 , disport four satisfying rocket boosters , is meant for commercial orbiter operators . This version vaunt an impressive load capacity , able to enchant up to 11.5 metric gross ton to GTO and 20 metric piles to LEO ( by compare , SpaceX ’s fully reclaimable Falcon Heavy candeliver63.8 measured tons to LEO ) .
Gallic company Arianespace is building the 203 - fundament - improbable ( 62 - meter - improbable ) rocket on behalf of ESA . The inaugural launch of Ariane 6 , ab initio slated for 2020 , was rescheduled to late 2022 , mainly due to the covid-19 pandemic and extra proficient hurdles encountered in its development . The maiden voyage of the rocket has been systematically delayed , with themost recent prognosis suggest an early 2024 launching .
Although the trial run , lasting 426 second , did not reach thetargeted470 second base , ESA and its partners still considered it a success . Over two hours were needed for dry land operations , which included fueling the rocket ’s central core and carry out a series of making run , all to ensure the launcher ’s wholeness and stableness . The upper stage tanks were also fire for the test , even though the upper point locomotive , designed to lick in blank space , was not part of this ground test . The CNES - managed launch pad was cardinal in the rehearsal , utilize its water soaker system to bring off the acute heat return during the test .
The Ariane 6 undertaking has become more vital following theretirement of the Ariane 5 rocket in Julyand the destruction of ESA ’s use of Soyuz rockets due to Russia ’s encroachment of Ukraine . These maturation have left Europe without an useable dwelling house - grown rocket .
The late rehearsal follow a series of earlier psychometric test , including abrief ignition and switch - off of the Vulcain 2.1 enginein September and afuel - draining testin October . The next milepost before ESA ’s initiatory launch is a hot fervidness test of the upper stage , scheduled for December 2023 at the DLR Lampoldshausen exam center in Germany .
