ESA examines human spaceflight role for Ariane 6 as Europe pushes for greater space autonomy

Berlin, June 12. As Europe intensifies efforts to bolster its strategic autonomy in space, the European Space Agency (ESA) is studying the possibility of adapting its Ariane 6 launcher to carry astronauts into orbit.

ESA Director General Josef Aschbacher said the agency is currently assessing whether the Ariane 6, Europe’s flagship heavy-lift rocket that has been operational for the past two years, could be modified for human spaceflight missions. Although the launcher has not yet been certified to transport crews, Aschbacher expressed confidence in the feasibility of the concept.

“We’re investigating this right now,” he told reporters at the ILA Berlin air show, adding that the prospects of turning the vehicle into a crew-capable system were “pretty high”, though some modifications would be necessary.

The issue of independent human access to space is gaining momentum in Europe. France is scheduled to host a space summit in September, while ESA plans to convene an inter-ministerial meeting in December to discuss future human exploration programmes.

Alongside work on Ariane 6, ESA is collaborating with Thales Alenia Space and The Exploration Company on the development of cargo return capsules that could eventually evolve into crewed spacecraft. Aschbacher noted that SpaceX’s Dragon capsule followed a similar trajectory, beginning as a cargo vehicle before being certified to transport astronauts several years later.

ESA hopes to demonstrate at least one of the capsule systems in low Earth orbit in the near future, although it remains unclear whether the missions would involve visits to the International Space Station (ISS).

Achieving independent human spaceflight capability would also require upgrades to supporting infrastructure, including Europe’s spaceport at Kourou in French Guiana.

Describing the initiative as a long-term undertaking, Aschbacher said that even if European governments endorse the programme this year, considerable time would be needed to develop the necessary capabilities.

“I think now is a good moment to reflect on this and make a decision on where Europe wants to go,” he said, underscoring the growing debate over Europe’s future role in human space exploration.
