Following its wet-dress rehearsal on the launch pad in French Guiana, Europe’s new Ariane 6 rocket is on schedule for its inaugural launch.
The European Area Company (ESA) introduced throughout a June 25 press convention that the rehearsal was a “full success.” After years-long delays, ESA is assured that their Ariane 6 rocket, deemed the way forward for Europe’s skill to launch satellites into Earth orbit, will lastly get off the bottom. ESA and French launch supplier Arianespace, which commercially manages the rocket, are getting ready for a launch on July 9. The three-hour window opens at 2 p.m. EDT (1800 GMT).
“After all, we’re nonetheless analyzing the info — it would take a number of days nonetheless. However all we’ve to date says that our child Ariane 6 is working completely,” mentioned Lucia Linares, head of technique and institutional launches at ESA.
The rehearsal came about on June 20. Operators first let the 295-foot (90-meter) rocket stand free on the pad, with out assist from its gantry, for the primary time ever. Then, they cooled the rocket to cryogenic temperatures and pumped it flush with gas, conducting methods checks all of the whereas, earlier than fully draining it in preparation for the precise launch. ESA will launch detailed outcomes from the take a look at later this week, however thus far, Ariane 6 seems to be functioning as deliberate, mission managers mentioned.
“All of the verification carried out did not proof any anomalous conduct,” mentioned Michel Bonnet, ESA’s principal for Ariane 6’s inaugural flight. “So, primarily based on that, we’re nonetheless very assured for the [July 9] launch date.”

The inaugural launch’s flight plan Ariane 6 as much as low Earth orbit (LEO) at an altitude of 320 miles (520 kilometers). This launch is not going to simply be a take a look at flight — as soon as up in orbit, the rocket will launch 9 cubesats. Additionally aboard Ariane 6’s Vinci higher stage are 4 non-orbital experiments, together with a tool that can take a look at a system for quickly finding satellites and two capsules that can drop from orbit into the Pacific with the intention to take a look at if they will re-enter Earth’s ambiance efficiently.
Vinci, nonetheless, will dissipate. The higher stage might be refired a number of instances as soon as in orbit, which might enable a single launch to deploy a number of satellites at completely different altitudes — and, as is deliberate for this primary flight — deorbit the spacecraft and stop it from floating endlessly as particles or falling to Earth uncontrolled.
The stakes for Europe’s launch capabilities are excessive. Ariane 6 is meant to interchange the venerable Ariane 5, which took off for the ultimate time final yr after 117 launches and 27 years of service. Since then, European launches have been depending on different — largely American — automobiles.
In these final days earlier than launch, ESA and its companions are eager to emphasise their dissatisfaction with this post-Ariane 5 establishment — and the chance for Ariane 6 to alter it if profitable. “It is a crucial second in European house historical past and for the sovereignty of Europe,” mentioned Carina Laveau, director of house transportation at CNES, France’s nationwide house company.
Ariane 6 is slated for round 9 to 12 launches per yr by 2026. Even earlier than the automobile’s inaugural flight, each nationwide house businesses and personal corporations have already booked 30 missions. The best-profile buyer is Amazon, which has thus far ordered 18 launches for its deliberate Kuiper satellite tv for pc constellation.
This primary launch was the truth is initially scheduled for 2020, however a battery of technical points — coupled with disruptions from each COVID-19 and the Russian invasion of Ukraine — have precipitated repeated delays. The failure of Europe’s fellow Vega C rocket in late 2022 has solely raised the stakes for ESA in relation to this new rocket.
Nonetheless, Ariane 6 officers expressed optimism that any troubles are firmly behind them. “We’re prepared for launch,” Linares mentioned.
