The European Space Agency has begun studying the feasibility of a European-led space station and is laying the groundwork for an independent crew transport capability, as its next generation of launch vehicles starts reaching orbit. The moves follow «A Call to Boost European Space Exploration,» recently endorsed by ESA member states, which asks the agency to strengthen Europe's position in human and robotic exploration of low-Earth orbit, the Moon, and Mars through competitive capabilities that include crew transport.
The push reflects a broader effort to secure independent European access to space. ESA Director General Josef Aschbacher said in an interview that Europe had been left exposed earlier this year when international partners changed their programs along the way, affecting projects and investments made with them. The agency now wants Europe to ensure its autonomy while remaining a strong partner for international collaboration.
Europe's next-generation launch vehicles have started coming online under ESA's European Launcher Challenge. The program booked its first success when Isar Aerospace's Spectrum reached orbit on its second flight on Sept. 5. The new rockets complement Europe's current vehicles, Ariane 6 and Vega C, which are ramping up flight cadence to meet an expected peak in demand around 2030.
Preparations for crew transport are tied to the planned decommissioning of the International Space Station, currently scheduled to begin in 2030. ESA and other ISS partners are working to ensure sustained access to low-Earth orbit. ESA ultimately wants a European version of all capabilities required for human spaceflight, including rockets, a crew vehicle, a launch abort system, space operations, science, and crew recovery. The Call names a European crew transport capability as a crucial step toward making Europe a central player in low-Earth orbit.
Aschbacher estimated that developing the capacity to launch European astronauts on European rockets and systems would take about 10 years and cost about 10 billion euros. If Europe does not do it, he said, it would still want astronauts in space and would need to buy that capacity in the United States, its current partner, covering both flight and station opportunities at a cost of about five billion euros. «So, for five billion extra we can do it ourselves and leave the money in Europe and therefore invest in our own capacity,» he said.
Although ESA has not publicized partnerships for developing crew transport, two European companies have announced plans for crew vehicles. The Exploration Company wants to develop a human-rated variant of its Nyx cargo capsule, and PLD Space is working on its LINCE capsule to fly on the forthcoming Miura Next rocket. ESA astronaut Matthias Maurer said in an interview that SpaceX's Crew Dragon is a very modern capsule and that he enjoyed his flight in it. He described it as a minimum standard for a European capsule, adding that he would challenge European designers to do at least as well and hopefully go one step beyond.
Before flying humans, Europe plans to establish its own commercial cargo delivery capability through Nyx. In September, ESA and The Exploration Company signed a contract for a demonstration mission to the ISS under ESA's Autonomous LEO Accelerated Demo Docking to ISS Node program, formerly known as the Leo Cargo Return Service and first announced in 2023. Nyx is set to fly its demonstration mission atop an Ariane 64 rocket, though its launch date remains unannounced. In 2025, the company targeted 2028 for Nyx's debut. ESA will fund the mission with 310 million euros as part of the ALADDIN contract, which totals 760 million euros; the remainder is designated for two more cargo missions to the ISS or a commercial successor.
With the ISS's retirement in sight, ESA has also initiated partnerships with companies working on commercial space stations. Last month, the agency signed separate agreements with United States-based Axiom Space and Starlab Space, a joint venture between U.S. company Voyager Technologies and European company Airbus Defence and Space. The agreements mark the first steps for Europe to obtain access to future commercial stations. ESA is already working with California-based Vast, which plans to launch its prototype station, Haven-1, early next year. The first human expedition to Haven-1 will include ESA astronaut Arnaud Prost on his first spaceflight. Vast is also organizing a private astronaut mission to the ISS that will carry ESA astronauts Thomas Pesquet, Aleš Svoboda, and Adrianós Golémis alongside a fourth astronaut yet to be announced.
This week, ESA announced it had started a pair of studies researching the feasibility of establishing a European-led space station. The agency is investigating that option in parallel with exploring partnerships with commercial stations, as it seeks to secure Europe's place in low-Earth orbit after the ISS era.
