Thomas Pesquet to Return to Space in 2027 for ISS Mission

French President Emmanuel Macron announced on Tuesday that astronaut Thomas Pesquet, a veteran of two space missions, will lead a new expedition to the International Space Station (ISS) in 2027—a mission that marks the first time a French astronaut will command a long-duration stay aboard the orbital outpost. The revelation, confirmed by the French National Centre for Space Studies (CNES), also signals that Arnaud Prost, another French astronaut, will accompany Pesquet on the flight, further cementing France’s expanded role in human spaceflight.

The mission, set to launch in late 2027, was framed by Macron as a testament to France’s renewed ambition in space exploration, particularly in the context of growing international competition and shifting dynamics in low-Earth orbit operations. According to CNES, Pesquet will assume the role of commander for the six-month expedition, a position that underscores France’s technical and logistical contributions to the ISS program. The agency did not specify the exact launch date beyond the 2027 timeframe but noted that preparations are already underway, including advanced training for both astronauts and coordination with international partners, including NASA and ESA (European Space Agency).

Pesquet’s appointment as commander is notable not only for its symbolic weight but also for its practical implications. As the first French astronaut to hold the position, he will oversee critical operations aboard the ISS, including scientific experiments, maintenance, and coordination with ground teams. The mission aligns with France’s broader strategy to deepen its involvement in Artemis program initiatives and other lunar exploration efforts, though officials emphasized that the 2027 flight remains focused on ISS operations. A CNES spokesperson stated that the selection process for the mission was based on Pesquet’s extensive experience—having logged over 365 days in space across two prior missions—and his leadership in international collaborations.

The announcement comes as France seeks to reinforce its position in Europe’s space sector amid geopolitical shifts. While the U.S. And China have accelerated their own crewed space programs, France has prioritized strengthening partnerships with ESA and other allies to ensure sustained access to low-Earth orbit. The inclusion of Prost, a relatively newer addition to France’s astronaut corps, reflects a deliberate effort to groom the next generation of spacefarers. Prost, who joined the European Astronaut Corps in 2022, will serve as a mission specialist, contributing to experiments in biology, physics, and technology development.

Diplomatic and institutional sources indicated that the mission’s timing is influenced by both technical readiness and strategic considerations. The ISS partnership, a cornerstone of international cooperation since the 1990s, faces uncertainties as some nations explore independent stations or commercial alternatives. France’s commitment to the ISS through 2030—aligned with the station’s planned operational lifespan—positions it as a key player in ensuring continuity. However, the absence of a public timeline for France’s potential involvement in post-ISS initiatives has left some questions unanswered about whether the 2027 mission will serve as a stepping stone for deeper lunar or Mars-focused ambitions.

For Pesquet, the mission represents a return to space after his last flight in 2021, during which he participated in over 200 experiments and conducted multiple spacewalks. His profile as a public figure—known for his engaging social media presence and outreach efforts—will likely amplify France’s visibility in the mission, though CNES has not yet detailed plans for live broadcasts or educational components. The agency’s focus remains on the scientific and operational aspects, with an emphasis on advancing research in microgravity environments.

The selection of Pesquet and Prost also highlights France’s investment in its astronaut training infrastructure. Both men underwent rigorous preparation at the European Astronaut Centre in Cologne, Germany, where they trained alongside international colleagues. The mission’s success will depend not only on their individual skills but also on seamless coordination with NASA’s Commercial Crew Program, which provides transportation to the ISS via SpaceX and Boeing. While no specific launch vehicle has been named, industry analysts suggest that SpaceX’s Crew Dragon remains the most probable option given its operational track record.

As preparations progress, the French government has signaled that the mission will be closely tied to national priorities, including defense, technology sovereignty, and climate research. Officials have not ruled out the possibility of additional French astronauts being assigned to future ISS rotations, though no further announcements are expected before 2026. In the interim, CNES and its partners will focus on finalizing the mission’s scientific objectives, ensuring compatibility with the ISS’s evolving schedule, and addressing logistical challenges posed by the station’s aging infrastructure.

The next concrete milestone will be the formal approval of the mission by the ESA Council, expected in the coming months. Until then, the focus remains on training, hardware readiness, and diplomatic assurances that France’s contributions—including funding for ISS operations—will be sustained. The absence of a public statement from NASA or ESA on the specifics of the mission underscores the ongoing negotiations over roles, resources, and long-term strategy in human spaceflight.
