Concerned about SpaceX, France to accelerate reusable rocket plans

"It's a real break from French strategy, and clearly inspired by the USA."

The new plan calls for the large, France-based rocket firm ArianeGroup to develop a new small-lift rocket called Maïa by the year 2026. This is four years ahead of a timeline previously set by the European Space Agency for the development of a significantly larger, reusable rocket.

Although the technical details are sparse, Maïa will not be Europe's "Falcon 9." It will have a lift capacity of up to 1 metric ton to low Earth orbit and be powered by a reusable Prometheus rocket engine, which is fueled by methane and liquid oxygen. This engine, which remains in the preliminary stages of development, has a thrust comparable to a single Merlin 1D rocket engine, which powers SpaceX's Falcon 9 rocket. But since there are nine engines on the SpaceX rocket, it can lift more than 15 times as much as the proposed Maïa in fully reusable mode.

The way I read this from what others have said this appears to be about crushing other small scale launchers in Europe rather than actually competing with Space X.
 
It will also dubiously stand in front of any future litigations... From public grandiloquent statements and funding to unlimited access into public R&D, this truly looks like a sheep in wolf clothing that wouldn't even beg to be tolerated on the market.
 
France’s CNES: There’s a mini-launcher competition in Europe. We intend to win it

The French government will subsidize development of ArianeGroup’s Maia reusable mini-launcher, and other French mini-launchers as well, to meet a competitive threat from other European small launchers, the president of the French space agency, CNES, said.

The decision was made after France concluded that mini-launchers are not just proving grounds for technologies intended for larger vehicles, but commercially valuable assets in the emerging satellite market.
 
In its recoverable mode the launcher loses two thirds of its payload capacity compared to when it’s just used in an expendable mode.

Small update from MaiaSpace: Maia will be capable of carrying 1,500 kg payloads to orbit in an expendable configuration. This is reduced by two-thirds to just 500 kg when it's being recovered. This shows the huge payload tax that's required for recovering these small vehicles.
 
Some good news for Maia:

ArianeGroup has committed to increasing its investment in the company’s launch startup subsidiary, MaiaSpace, from approximately €40 million to €125 million.

MaiaSpace was founded in late 2021 with the aim of developing a partially reusable microlauncher. The standard two-stage configuration of the Maia vehicle will be capable of deploying 1,500 kilograms into low Earth orbit when the first stage is expended and 500 kilograms when it is being recovered. However, with the addition of the Colibri kick stage, the vehicle’s performance will increase to 2,500 kilograms to low Earth orbit when the first stage is expended.

Since its founding, ArianeGroup has invested approximately €40 million into the fledgling launch company. This has allowed MaiaSpace to grow to over 115 employees, construct a prototype of the Maia second stage, which has undergone cryo testing, and test-fired the engine that will power the Colibri kick stage all in just two years of operation.

As MaiaSpace pushes forward to its ambitious goal of a maiden launch attempt in 2025, ArianeGroup has committed an additional €85 million to the cause. This makes the company one of the most well-funded launch startups in Europe, surpassing Orbex’s €115 million and only falling short of the impressive €310 million raised by Isar Aerospace. However, the €125 million invested in MaiaSpace doesn’t tell the whole story.

To boost the pace at which it develops Maia, MaiaSpace is utilizing the work done by ArianeGroup for its ESA-contracted Themis and Prometheus programmes. Maia will utilize three Prometheus engines for its first stage and a single vacuum-optimized Prometheus engine for its second stage. As for Themis, considering recent reporting confirming that Maia will stand at 50 metres tall, it’s likely that the very little of the 30-metre tall Themis booster will be left behind.

To date, over €300 million in combined funding has been spent on Themis and Prometheus. This, when added to the €125 million supplied by ArianeGroup, is a more accurate but not perfect overview of the funding that has gone and that will still go towards the development of Maia.

 
Amazing how the money and IP flow freely to a private ownership without any safeguard or rational guarantee of any proven success.

If the methalox doesn't lift that rockets, would the pile of public money do? (yes, yes, a green startup per se).
 
So about Themis, the demonstrator that Maia's First stage is derived from...

Last year Arianegroup tested Themis landing legs developped by the Swiss company Almatech with ESA funding from the FLPP program...


And now the German company MT Aerospace is testing Themis landing leg they developped with funding from the EU "SALTO" program (as part of "Horizon 2020")...

Talk about inefficiency!
Now from what I understand, the former is for the First, single-engine Themis hopper (T1H), and second is for the second, three-engines Themis hopper (T3), which are two different vehicles, but with the same size, which will launch from two different launch pads (Esrange and Kourou) for two overlapping programs...

And beyond that, it looks like Maiaspace is also developping their own leg design, despite their first stage being very close to the Three-engines Themis, the legs in some of the recent renders look noticeably different from MTA's

A good case of european industrial organization mess...

Meanwhile in China, a country that 10 years ago, had less advanced launcher technologies, and not a single private space company:

All of these are the size of a small launcher's first stage, like Themis/Maia

"Aw, China is just copycats.."

(And you go right on thinking that, hey-sir.)
 
All it means is that they are pretty good at it.
Except for bolting demonstrators to Earth solid ground, when they test them :p

I'm not that shocked the Chinese churn copies of F9R and Starship. I mean, look at Caravelle & DC-9, 727 & Trident, Lockheed L-2000 & Concorde & Tupolev 144. Bottom line: there are not many ways to re-invent the wheel.

True, but my impression as a lay person and someone who is most definitely not a historian of Chinese industrial history is that China largely stopped coming out with original inventions and instead started copying other's ideas about a millennium ago.
 
Good news
Maiaspace got the right to transform the disused Soyuz launch pad at GSC.


What their press release doesn't say is that they'll likely have to share this pad and infrastructure, since as part of the 2023 ESA Ministerial agreement the Soyuz launch area would be shared between one CNES-selected launcher and one ESA-selected launcher.

Sharing the launch pad will likely hinder their "perspectives of growth in terms of launch rate.", there is also an increasing french governmental/army interest in maiaspace as reusable launcher for national payloads. I wouldn't be surprised if CNES/France influences ESA's selection so that they also pick Maiaspace, or at least a french launcher.

It reminds me of the Wenchang commercial launchpads and its countless shared launchers... Not ideal for RLVs, F9's success was built on the parallel and exclusive use of 3 different (and already built) launch pads.

--

From the point of view of infrastructures, they will seemingly remove the Mobile Gantry (MBO), likely because it's too small for Maia, it's tailored for Soyuz's size and specific mix of horizontal and vertical integration, and also because it's still legally Russian-owned. They seem to keep the MIK assembly hangar and the oxygen tanks of Soyuz's fuelling system. Another article says that they ordered a (rail-adapted) Transporter-Erector for Maia.

A quick scale comparison between Soyuz-ST and Maia:

They are. All it means is that they are pretty good at it. Show me *one* single *original* Chinese aerospace concept.
Whatever Qian Xuesen worked on? :)

The Maia LV is larger than I thought…O/T wasn’t there to be an R-7 evolution where all the cores were to be cylindrical (making it resemble Shenzhou’s launcher) and use N-1 engines?
 
A lot of new papers..and not just on aerospace…are coming out of China—just browsing phys.org will make that clear.

Their current LVs do look a lot like Musk’s, but they are either R-7 size or a bit bigger than Falcon for whatever reason.

They improved on Soyuz.
There are only so many LV designs…had they gone plug nozzle folks would say they ripped off Phil Bono.

You're probably thinking of the late 90s/early 2000s "Yamal" project by TsSKB-Progress, conceived as an alternative to Angara, which used NK-33 on its core and modular, NK-33 powered cylindrical boosters that were to be shared with another "Polyot" smaller launcher. It's one of the projects that eventually evolved into Soyuz 2.1v

As for Maia, yeah it's quite big, it uses the same 3.5m diameter and stainless steel tanks as Themis does, so the whole thing; in size; is only a bit smaller than a Falcon 9 1.0; however since methane is less dense than kerozene and (conventional) steel tanks are heavier than aluminium, the performances are quite lower (Maia has been advertised as 4 tons to LEO)

Here's some pictures of the Maia and Themis tanks and stages at Arianegroup's plant in Vernon

Taking a closer look at SALTO: Performing Europe’s first reusable launcher flight campaign [Jun 27]

The Themis T1H vehicle arrived on June 27 2025 at the launch site in the ESRANGE Space Center. The flight campaign will begin with the assembly of key landing components, such as landing legs.

The vehicle will then be prepared for a wet rehearsal, during which cryogenic propellants will be loaded into the vehicle for the first time. This will be followed by a static hot-firing test, where the engines will be ignited to validate stage under realistic conditions.

The first low-altitude "hop"- a vertical takeoff and landing maneuver - is planned before the end of 2025, and two additional hops are scheduled for early 2026.

The first model of the European Space Agency’s (ESA) reusable rocket demonstrator Themis is standing at its launch pad in Kiruna, Sweden.

Themis is investigating technologies to demonstrate rocket stage recovery and reuse. The first vehicle model – called T1H for Themis-1 engine-Hop – arrived at the Esrange Space Center over the summer, with its landing legs shipped separately. The legs are now installed, and T1H is standing tall. Themis is set to be the first European demonstration of a full-scale vertical take-off and landing rocket element that uses cryogenic propulsion. T1H is 30 m tall standing on its legs and 3.5 m wide, holding the necessary technologies for the low-altitude take-off and landing tests it is set to perform. Themis uses the Prometheus engine, almost as powerful as the Ariane 6 rocket’s main engine – but Prometheus can restart in flight and throttle its thrust to ensure a soft and safe landing. Themis was transported by truck over 3000 km from the ArianeGroup integration building in Les Mureaux, France, to the Swedish Space Corporation’s Esrange Space Center in the north of Sweden. After final check at a Kiruna assembly building, Themis was moved to the pad in August and hoisted onto a tool to allow the swift assembly of its four legs. This is the first time the rocket stage demonstrator has had its four legs installed, now the demonstrator is fully assembled and ready for its wet dress-rehearsal preparing for a first flight. Themis, the first European reusable main stage’s full-scale demonstrator, was developed by ESA’s future Space Transportation preparation programme, with ArianeGroup as prime contractor and multiple European industrial partners. Themis’s first flight campaign with T1H, will be realised in the scope of Horizon Europe project Salto, funded by the European Union. The Salto project is responding to the EU Space Research and Innovation Programme and is implemented by 25 consortium partners from 12 European Union countries.

Successful Fit-Check of the Maia Launcher!

Earlier this September, our teams completed a rehearsal of mechanical assembly operations, aka "fit-check" of the #Maia launcher at our Proto-Factory in Vernon — a key step in preparing for future flight models and industrial-scale production.

This full-scale integration of #Maia (over 50 meters tall and 3.5 meters in diameter) involved the sequential assembly of:
The Multi Engine Bay
The Main Stage
The Inter Stage Structure (ISS)
The Upper Stage
And finally, one Landing Leg prototype

This key operation allowed us to:
✅ Validate all mechanical interfaces between main structures
✅ Confirm the integration sequence and optimize workspace efficiency for future assemblies
✅ Test and validate torque tightening techniques for all bolted joints
✅ Validate operationnal performance of some tailored-built handling tools

With this milestone achieved, MaiaSpace is gearing up build for first flight models integration — and paving the way toward industrial-scale production, targeting around 20 launches per year by the early 2030s in our future Maia Factory, set to be operational by 2027.

U-Space has selected MaiaSpace to launch the TOUTATIS mission, a space-action demonstration involving 2 low-Earth-orbit satellites, on behalf of the French Defence Innovation Agency (AID) and for the benefit of the French Space Command (CDE).

The two satellites, with a total launch mass of 200 kg, will fly aboard the Maia launcher, scheduled for 2027 from the Guiana Space Centre. They will be deployed simultaneously into a sun-synchronous orbit.


TOUTATIS (In-Orbit Test of Action Techniques Against Space Interference Attempts) is a project developed by U-Space in partnership with MBDA to carry out cooperative or adversarial scenarios in space.
It uses a pair of satellites operating together : Lisa-1, dedicated to space surveillance, and Splinter, capable of close approach and action.
This first demonstration will implement a complete acquisition, decision-making, and reaction chain in low Earth orbit.
 
The CEO of Eutelsat on their needs at around ~56 min

In short :

Priority goes to Ariane 6 and the Maia launcher​
They need to renew their existing fleet of LEO satellites, which means sending a few satellites per orbit, not huge batches like Starlink.​
They are counting heavily on Maia to launch small batches of about 10 satellites per orbit, compared to 90 on Ariane 6 and 45 on Falcon 9.​
While waiting for Maia, there will be a few Ariane 6 and Falcon 9 launches.​
They also want to sign for a few launches with Indian launchers as an alternative to the US (India is a shareholder).​

Some news

MaiaSpace wants to recover a rocket first stage at sea starting in 2028

Founded in 2022, the French company MaiaSpace is a subsidiary of ArianeGroup created with the goal of rapidly designing a new medium-class orbital launcher that is very cost-efficient and partially recoverable and reusable. Today, the young company is targeting a first flight by the end of 2026 and is already moving forward on its future booster-recovery capability, which will require new maritime assets never before used in France: a barge and a tugboat built specifically for MaiaSpace’s needs.

Now 350 employees.

Tests carried out in Vernon (Eure) in 2025 on several prototypes of the various components of the future Maia rocket were judged very satisfactory.

The first stage is planned to be reusable up to 5 times.
Around twenty launches per year are expected starting in the next decade.
The cost of placing payloads into orbit per kilogram will be only slightly higher than that of heavy launchers such as Ariane 6 or Falcon 9.

The MaiaFactory in Vernon should become operational in 2027.
Maia will take over the former Soyuz launch pad in Kourou.

The first launch is hoped for at the end of 2026.
They want to succeed with their first launch within five years of the start of the MaiaSpace project in April 2022.
This first flight will not be orbital but suborbital (parabolic).

A second launch is planned for 2027.
It could be orbital.
This flight will be intended to validate the overall configuration, the various components, the flight control laws, stage separation, and so on.

They then want to recover their first stage starting in 2028 — this should be the 8th or 9th launch.
They will use a barge to recover it at sea.
However, this recovery could possibly be preceded by a precision splashdown.

A European shipbuilder has been selected to design and build this barge according to MaiaSpace’s strict specifications.
MaiaSpace should soon select a design for the tugboat, which will also serve as a sea-based command post.
Both the barge and the tugboat will therefore be brand-new vessels, specifically designed to meet MaiaSpace’s requirements.

Maia will be capable of carrying between 500 and 2,500 kg to orbit depending on the configuration:
  • With or without recovery
  • With or without the “Colibri” kick stage
  • Depending on the selected orbit
Yohann Leroy, CEO of MaiaSpace, provided more details on future evolutions of Maia:
“We have proposed, notably as part of the European Launcher Challenge, a version of Maia equipped with four Prometheus engines on its first stage instead of three today, which would provide one-third more thrust on the first stage. The second stage would keep a single Prometheus. The tanks would be enlarged on both stages, and we would slightly rework the staging — in other words, the distribution of loads between the first and second stages. The launcher would be a bit taller, but its diameter would remain unchanged, and the engines would be of the same type as those of the current Maia. This means that this evolution would be much simpler to implement than developing an entirely new launcher, as some of the other European Launcher Challenge winners are considering.”
With an equatorial ecliptic orbit payload capacity approaching nearly 4 tons (without stage recovery), Maia already positions itself as a direct competitor to the Vega-C rocket, and even to the future Vega-E, far ahead of other European start-ups.
 
Eutelsat Awards MaiaSpace Multi-Launch Contract for OneWeb Satellites

French rocket builder MaiaSpace has signed an agreement with Eutelsat to perform multiple launches to support the expansion of the company’s OneWeb satellite constellation.



On 15 January, MaiaSpace announced that it had secured a multi-launch agreement with Eutelsat to deliver satellites for its OneWeb constellation to low Earth orbit. According to the release, the agreement has the potential to account for “the majority of [the] Maia launch manifest during the first three years of operation.”

“This agreement with an experienced and renowned satellite operator confirms that Maia is well-suited for deploying or replenishing satellite broadband constellations,” said MaiaSpace CEO Yohann Leroy. In the aftermath of the ESA ministerial conference, where key decisions were taken on the European Launcher Challenge and access to the European institutional market, MaiaSpace already stands on the two pillars needed for economic viability: being competitive on the commercial market while [being] considered strategic for Europe’s sovereign access to space.”

 
According to a 29 January call, CNES revealed that MaiaSpace had formally vacated the ELM launch facility in the last quarter of 2025. As a result, the agency is calling for interested launch operators to fill the vacancy left by the ArianeGroup subsidiary.
