Reaching space is becoming more routine. Returning valuable cargo safely remains a specialist service. The Exploration Company wants to change that with Nyx, a reusable spacecraft intended to fly aboard different heavy rockets, visit space stations in low Earth orbit and carry as much as three tonnes back to Earth.
The European space startup raised $450 million in Series C funding earlier this month, in what it described as the largest Series C secured by a European space company. The round brought its total funding to approximately $680 million.
Two days later came an equally important vote of confidence. The European Space Agency awarded The Exploration Company a service contract for an initial Nyx demonstration mission to the International Space Station, with options for two subsequent cargo flights to the ISS or a future commercial station. The first mission is expected to launch aboard Europe’s Ariane 6 rocket.
The funding may have attracted the headlines, but the more interesting story is the space transport system taking shape behind it: one designed not around a single destination or, eventually, a single launch provider.
The people behind The Exploration Company
The Exploration Company was founded in 2021 by Hélène Huby and a group of engineers who had worked on major programmes at Airbus and ArianeGroup.
Huby was previously vice-president of the European Service Module for NASA’s Orion spacecraft at Airbus Defence and Space. Built in Europe, the module provides Orion with propulsion, power, water and air on missions beyond low Earth orbit.
That experience exposed a curious gap. European engineers could build a critical part of a spacecraft designed to carry astronauts towards the Moon. The continent could also produce rockets, satellites and modules for the International Space Station. Yet it did not operate its own reusable capsule capable of taking substantial cargo into orbit and returning it intact.
The founding team set out to combine expertise from Europe’s established aerospace industry with a faster, venture-backed development model.
The Exploration Company now employs more than 550 people across Germany, France, Italy, Spain and Luxembourg, with offices in the United States and the United Arab Emirates. Its leadership and board draw heavily on established space programmes. Kathy Lueders, who previously led NASA’s human-spaceflight operations and later worked at SpaceX, advises the chief executive. Former Airbus chief technology officer Grazia Vittadini and former NASA administrator Mike Griffin sit on the board.
This is a young company, but not one learning spacecraft engineering from scratch.
A reusable capsule that crosses company boundaries
SpaceX has demonstrated the advantages of controlling almost the entire journey. It designs and operates the Falcon 9 rocket, Dragon capsule, software and supporting infrastructure. Because those components were developed as one system, SpaceX can optimise their performance and operation together.
The Exploration Company is making a different bet. It expects the next phase of the space economy to need vehicles capable of crossing corporate and national boundaries.
Nyx is being designed to launch aboard more than one type of heavy rocket. It should also be able to serve both the ISS and the privately operated stations expected to follow it.
If SpaceX resembles Apple, with hardware and software controlled within one ecosystem, Nyx aspires to something closer to Android: a common platform capable of working with several providers.
The comparison has limits. Nyx is a physical spacecraft, not software distributed to manufacturers. Nor could it simply be placed on any available rocket. Every combination would require mechanical connections, communications, software and safety systems to be integrated and certified.
Interoperability is therefore a design objective, not yet a proven feature. The first full-scale flight is tied to Ariane 6, although the company says future missions will not be confined to one launcher.
Building for commercial space stations
The timing is deliberate. The International Space Station is expected to retire around 2030, and NASA wants privately operated stations to assume some of its role in low Earth orbit.
Axiom Space, Starlab and Vast are among the companies developing possible successors. Each has reached an agreement with The Exploration Company for future transport services.
These stations would need food, equipment and experiments delivered. They would also need waste removed and scientific samples, manufactured materials and faulty components brought home. If several destinations and launch providers enter service, a capsule capable of connecting them could become the delivery van of a new orbital neighbourhood.
But that is also the commercial risk. Private space stations are enormously expensive, technically difficult and likely to depend heavily on government agencies as customers. Some proposals may be delayed, combined with competing projects or never built.
The Exploration Company is constructing a delivery network before anyone knows how many addresses it will serve.
How the Nyx reusable spacecraft will work
A rocket will carry Nyx into orbit, after which the capsule must separate and operate independently. It will navigate towards a station, dock autonomously and exchange cargo before beginning the return journey.
Re-entry is the brutal part. The vehicle must decelerate from orbital speed while its heat shield protects it from extreme temperatures. Parachutes then slow the final descent before splashdown and recovery.
The company says Nyx will be capable of returning up to 3,000 kilograms and being reused for as many as ten missions. Both remain targets until the full-scale vehicle flies.
Return capacity may prove to be Nyx’s most important commercial feature. Several cargo vehicles can deliver supplies to the ISS but are deliberately destroyed in the atmosphere after being loaded with waste. SpaceX’s Dragon is currently the main Western spacecraft able to bring substantial payloads back.
For companies hoping to produce pharmaceuticals, advanced materials or biological products in microgravity, that downward journey is not an optional extra. Manufacturing something in orbit has limited commercial value if it cannot reach a customer on Earth.
What happened to Mission Possible?
The Exploration Company has already launched two smaller demonstrators. Neither completed its planned mission, although both contributed to the programme.
Bikini, a roughly 40-kilogram re-entry demonstrator, was developed in nine months and launched aboard the inaugural Ariane 6 flight in July 2024. A problem with the rocket’s upper stage prevented it from releasing Bikini onto the required re-entry trajectory. The capsule remained attached to the stage, so its heat shield could not be tested in flight.
Mission Possible was considerably more ambitious. Launched aboard a SpaceX Falcon 9 in June 2025, the 1.6-tonne capsule carried around 300 kilograms of customer payloads.
It reached orbit, stabilised itself and began a controlled return to Earth. The capsule survived the part of the journey that looks most frightening: plunging into the atmosphere behind a heat shield while hot, electrically charged gas temporarily blocked radio communications.
After the expected blackout, its signal returned. Mission Possible had made it through re-entry.
Then contact was lost during the final descent, shortly before the planned splashdown in the Pacific. The capsule and its payloads were not recovered. The company characterised the flight as both a partial success and a partial failure: it had demonstrated controlled re-entry, but not the safe landing and recovery customers would require.
Since then, The Exploration Company has continued testing the descent system. In June 2026, it reported successfully dropping a test vehicle from a helicopter and deploying the drogue and main parachutes in sequence.
Nyx begins with cargo, not astronauts
ESA’s new ALADDIN contract turns the next flight into more than another company demonstration. It makes the agency an anchor customer for a European cargo service.
The agreement covers a Nyx mission to the ISS and options for two later flights. ESA will fund 60 per cent of the demonstration, with The Exploration Company securing the remaining 40 per cent from private investors. The mission is planned for 2028.
Beyond low Earth orbit, the roadmap becomes more ambitious. The company wants to adapt its spacecraft for lunar cargo missions and eventually human transport. It is also developing Storm, a high-thrust rocket engine, as part of a longer-term effort to control more of the journey.
Those plans remain more distant. First, Nyx must demonstrate autonomous docking, controlled re-entry and safe recovery in one uninterrupted mission.
Investors have supplied the money. ESA has supplied an anchor contract. Future station operators have supplied signs of demand.
In 2028, Nyx must supply the missing proof: a complete journey to orbit and safely home again.
