Europe’s first new heavy-lift rocket in almost 30 years soared into space on Tuesday, promising an end to a crisis over the region’s ability to deploy its own satellites into orbit.
Ariane 6, four years late and heavily subsidised to ensure it can compete against Elon Musk’s SpaceX, lifted off under clear skies from its launch pad near Kourou in French Guiana at about 4pm local time.
The mission was judged a success by the European Space Agency which oversees the Ariane programme, despite the rocket encountering a problem with its auxiliary power unit in the final phase of the flight.
Josef Aschbacher, director-general of the ESA, was jubilant after Ariane 6 released its satellite payloads into orbit roughly one hour into the mission.
“We are making history now,” said Aschbacher. “There is still a bit of work to do but . . . this is such a beautiful moment.”
Technicians and engineers in the Guiana Space Centre’s Jupiter control room, many of whom have spent a decade working on the programme, applauded as the rocket flew through a series of milestones.
The most important was demonstrating that the Vinci engines powering the rocket’s upper stage could be stopped and restarted to deposit satellites into different orbits roughly 600km above earth.
However, the rocket’s auxiliary power unit — used to enable the reignition of the Vinci engines — encountered problems in the final stage of the flight.
The ESA insisted on the social media platform X that this only affected the end of the mission. “Ariane 6 demonstrated a successful lift off, launch to orbit and deployment of satellites powering Europe into space,” it said.
The launch should restore Europe’s independent access to space, where nations are battling to gain strategic and economic advantage.
But there are questions over how competitive Ariane 6 will be against Musk’s reusable Falcon 9 rocket, or his far bigger Starship, which this year completed a successful test flight into space.
Last year the 13 ESA member states that helped fund Ariane 6 agreed a €1bn subsidy over three years, on top of the programme’s estimated €4bn development cost.
An end to co-operation with Russia’s Soyuz programme after its invasion of Ukraine, and delays to Italy’s new Vega-C rocket as well as Ariane 6, have exacerbated European concerns about sovereign access to space since the retirement of Ariane 5 last year.
Europe has been forced to turn to SpaceX to launch four important satellites, including two for the Galileo navigation system, while four more will fly with the US company later this year.
As a result Europe is reviewing the way it collaborates on launcher programmes.
Last year the ESA, which has 22 member states including the UK and Switzerland, launched a competition to buy micro launch services from the private sector. Some of those companies may eventually snare business from Ariane.
German rocket start-up Rocket Factory Augsburg last week described Ariane 6 as “overpriced”, saying its development “at the taxpayer’s expense has shown that something has to change”.
But even RFA welcomed Ariane 6’s flight as a significant moment for Europe.
“Europe has finally regained autonomous access to space and can once again play an active role in shaping global space travel,” said co-founder Jörn Spurmann.
Ariane is expected to make its first operational flight by the end of the year. It is already booked for 29 launches, of which 18 will be for Amazon’s Project Kuiper broadband satellite constellation, expected to start in 2025.
The Ariane 6 programme has been criticised because the rocket will not be reusable, unlike Falcon 9.
However, manufacturer ArianeGroup, and launch service provider Arianespace, are hoping that the rocket’s flexibility will give it an advantage over SpaceX.
