Wrong, no Thales Alenia in Germany. If Germany has the majority stake in the program... you can imagine how it ends.

ESA works on the policy of geo-return as you pointed out. A similar fraction of money contributed by each member state should be spent by companies in the same country as a rule of thumb.

The bulk of the cost of the program would be on hardware development and procurement so if the contractor manages to use German suppliers for some critical equipents geo-return can be balanced out. Germany is good at Engines, tanks and valves.

The Modules will remain the same. They have already been negotiated against Orion seats to Gateway.

Never seen a negotiation where you get more with the same bargaining chip.

I think that the new bargaining chips are Argonaut and Moonlight. Presumably, ESA could trade these for a trip from Gateway to the lunar surface.

Ok so we are back to my original question.

My impression is that Starship with its low operating cost and huge payload to Lunar surface reduces considerably the bargaining power of the pair Ariane 64 / Argonaut.

So do I miss something which makes Ariane 64 / Argonaut against ESA astronaut on the surface a palatable deal for NASA much more than I think ?

I see what you mean but I think that the argument is that NASA and its Artemis partners need small cargo (CLPS), medium (Argonaut) and large cargo capability (cargo HLS-Starship) to the lunar surface. Argonaut would fit into the medium cargo capability.

The argument for three sizes is only valid if smaller is cheaper. IF starship works at all, and IF (big if) an expendable Starship is cheaper (single unit cost) than a smaller launcher, then this argument disappears. Of course Starship will also crush the competition for any lunar destination that is the target of multiple payloads that are collectively too large for the smaller landers. The huge Starship may end up being cheaper than smaller landers because Starships are to be made in high volume from cheap standardized materials. Finally, a landed expended Starship is a resource that can be used as is or broken up for parts and materials.

I think that it is similar to smaller LVs. There is likely a need for smaller dedicated lunar missions. Flying Starship for a small cargo is overkill. Starship has yet to be awarded any CLPS missions, even though they are a potential provider.  NASA has yet to award any missions for HDL (HLS-cargo) also. HDL would be used for the pressurized rover and the foundation surface habitats but that's about it. I am not skeptical that Starship will work but I am skeptical that a Starship will be as cheap as what is expected (at least in the short term). The Artemis IV HLS-Starship is costing NASA $1.15B, so I am guessing that an HDL cargo mission would be about half that price.

Quote from: Toni Tolker-Nielsen, ESA
As an alternative to increase Ariane 6 performances, we are looking at in-orbit refueling, working on an Argonaut concept with in-orbit refueling to increase its performance. So, with two Ariane 6s, we launch a full reservoir and an Argonaut with its payload and little fuel. Then we will dock to the tank to refuel. This scenario gives a big increase in performance to get cargo to the Moon surface. Argonaut is a European lunar lander that will provide autonomous access to the Moon for Europe, allowing us to play a major role on the surface of our natural satellite. In the 2030s, Argonaut, launched on Ariane 6, will deliver up to 2,100 kg of cargo to the Moon’s surface.

This quote is from a recent Space News interview with Toni Tolker-Nielsen, ESA director of space transportation:

Argonaut: a first European lunar lander
30/01/2025

The European Space Agency (ESA) has signed a contract with Thales Alenia Space in Italy to lead European aerospace companies in building the Argonaut Lunar Descent Element, ESA’s first lunar lander.

ESA’s Argonaut represents Europe’s autonomous and versatile access to the Moon, supporting international exploration endeavours on the lunar surface. From the start of the next decade, the spacecraft will launch on regular missions to the Moon. These could deliver infrastructures, scientific instruments, rovers, technology demonstrators and vital resources for astronauts on the lunar surface such as food, water and air. Argonaut will be able to survive the harsh lunar night and day for five years, providing a key capability for sustainable lunar exploration.

Argonaut is a cornerstone of ESA’s lunar exploration strategy and is designed to work seamlessly with ESA’s Lunar Link on the Gateway and Moonlight communication and navigation systems. Argonaut is one of Europe’s contributions to international lunar programmes, particularly NASA’s Artemis programme and commercial lunar lander services, contributing to establishing a permanent and sustainable human presence on the Moon.

The spacecraft for an Argonaut mission has three main components: the lunar descent module that takes care of flying to the Moon and landing on target, the payload, and the cargo platform that acts as the interface between the lander and payload.

Thales Alenia Space in Italy will be leading the European consortium to build the lunar descent module; the rest of the core team includes Thales Alenia Space in the United Kingdom and France, and OHB.

The team will deliver the Argonaut Lunar Descent Element in 2030 for the first operational mission, ArgoNET, expected in 2031. By the end of 2026, the industrial consortium in charge of using the first Lunar Descent Element will be selected.

"The Argonaut contract signature is a pivotal moment for Europe’s lunar exploration ambitions,” says Daniel Neuenschwander, ESA Director for Human and Robotic Exploration.

“This first-of-its-kind European lunar lander demonstrates ESA’s dedication to advancing our industrial capabilities in deep space exploration. Argonaut will enable Europe to contribute meaningfully to international partnerships, while paving the way for a sustainable human presence on the Moon. Europe is on its journey to the Moon and has broken the ground towards European autonomy in exploration," he adds.

Thales Alenia Space signs contract with ESA to develop the Argonaut Lunar Lander for cargo delivery [Jan 30]

Quote
Thales Alenia Space, has signed a contract with the European Space Agency (ESA), worth € 862 Million, related to the design, the development and the delivery of the Lunar Descent Element (LDE) for ESA’s Argonaut Mission, including responsibility for mission design and integration.

Planned to be launched from the 2030s, Argonaut will deliver cargo, infrastructure and scientific instruments to the Moon’s surface.

The first mission is envisioned to deal with delivery of dedicated navigation and telecommunication payloads as well as energy generation and storage system, as European enterprises to explore the Lunar southern area.

About Argonaut

The Argonaut spacecraft consists of three main elements: the lunar descent element (LDE) for flying to the Moon and landing on the target, the cargo platform one, which is the interface between the lander and its payload, and finally, the element that the mission designers want to send to the Moon.

Adaptability is a key element of Argonaut's design, which is why the cargo platform is designed to accept any mission profile: cargo for astronauts near the landing site, a rover, technology demonstration packages, production facilities using lunar resources, a lunar telescope or even a power station. The project will strengthen Thales Alenia Space’s skills in several technological areas essential to space exploration beyond the Moon.

The future space ecosystem requires new solutions dedicated to the transport and return of cargo from low Earth orbit and lunar orbit, as well as crew transport to low Earth orbit. Thales Alenia Space is ready to put in place what is needed to prepare for humanity’s future life and presence in Space, laying the foundations for the post-ISS era and meeting new economic needs for research and science.

Argonaut consortium: who does what?

Thales Alenia Space is the prime contractor for the development of the Lunar Descent Element. The overall mission responsibility, ie the use of the LDE and integration with payload, will be the subject of a separate procurement in the future. The Lunar Descent Element is an independent architecture block of the international lunar exploration activities, namely a versatile system to support a variety of missions.

As prime contractor and system integrator of the Lunar Descent Element, Thales Alenia Space in Italy will lead the industrial consortium that will be responsible for the system, the entry descent and landing aspects, as well as the general and specific architectures of the thermomechanical, avionics and software chains. Thales Alenia Space in France and in the UK will respectively focus on data handling systems and propulsion. OHB System AG as additional core team member of the Thales Alenia Space consortium will be responsible for guidance, navigation and control (GNC), electrical power systems (EPS) and telecommunications (TT&C) aspects.

“Argonaut lunar lander means a lot to our company” said Hervé Derrey, Thales Alenia Space CEO. “Thanks to this astonishing space vehicle, tons of cargo will be delivered to the Moon’s surface, including rovers, scientific missions and many more. This new element of the Artemis program will serve at facilitating long-duration manned lunar exploration missions and will be crucial to increase European autonomy in lunar exploration. The Moon will also serve as a stepping stone for crewed missions into deep space, with Mars being the next stage of the journey. I wanted to express my gratitude to ESA for awarding this new contract to our company. Today’s major achievement strengthens more than ever Thales Alenia Space’s leading positions in the fields of space transportation systems, orbital infrastructures and space exploration”.

“We are truly honored that ESA has renewed its trust in our company by awarding Thales Alenia Space this major contract to develop the European lunar lander that will enable Europe to access autonomously to the Moon’s surface”, said Giampiero Di Paolo, Deputy CEO and Senior Vice President, Observation, Exploration and Navigation at Thales Alenia Space. “Today, with its longstanding expertise in space exploration infrastructure and vehicles, our company, in line with ESA’s and ASI’s visions, has decided to enhance its competitiveness by investing in the development of technological solutions to help Europe achieve its goals. Supplying a significant proportion of the International Space Station’s pressurized volume, playing a major role on board Artemis, manufacturing the backbone of Orion’s European service module and leading flagship transportation programs such as IXV or Space Rider, Thales Alenia Space is more than ever at the forefront of exploration and space transportation systems”.

It is ironic that once the foreseeable cancellations occur, this might well be the only thing left of ESA's lunar exploration initiatives...

Maybe because in Europe, old space companies are pretty good at delivering on big projects like this with tight budgets and deadlines? ArianeGroup is a notable exception, sure. I'd admit that. Thales Alenia Space is incredible, though. I think they are absolutely the best people to execute on Argonaut.

Agreed, TAS seems like the perfect company (maybe anywhere in the world) for this particular project. There simply is no New Space co in Europe of the size, competence, and wherewithal that could be trusted to execute such a project. That being said, it would be healthy for the European space industry, and increasingly so going forward, for there to be serious New Space options in Europe.
