Axiom Space Selects Emiliano Ventura as First ‘Project Astronaut’

Axiom Space has appointed Portuguese physiologist Emiliano Ventura as the inaugural leader of its new initiative, “Project Astronaut.” Announced during the 2025 International Astronautical Congress on Tuesday, this program aims to enhance astronaut training protocols as Axiom prepares to launch the first module of its commercial space station next year.

Ventura, who serves as the director of the Motor & Sport Institute (MSI) Bio Performance Center, will develop a six-month training program that integrates his expertise in physiology and sports science. “I am honored to participate in Axiom Space’s first Project Astronaut initiative, combining my expertise in human performance with astronaut training,” he stated. Ventura further emphasized that the program is designed to advance scientific research while inspiring both the people of Portugal and the global community to engage with the future of space exploration.

The collaboration between Axiom Space and MSI is not new; the two organizations have worked together since at least Axiom Mission 3, which launched in January 2024. As part of Project Astronaut, Ventura’s training regimen will incorporate various elements, including centrifuges, parabolic flights, altitude chambers, outdoor leadership exercises, and spacesuit operations training.

Innovative Training for Future Missions

Ventura’s goal is to gain insights into how the human body adapts to microgravity conditions, leveraging his extensive background in the field. Michael López-Alegría, Axiom Space’s Chief Astronaut, remarked, “Project Astronaut embodies Axiom Space’s dedication to mission readiness and continuous improvement. Emiliano is the perfect candidate to lead this pilot program given his unique combination of expertise in human performance and extensive experience training previous crew members.”

The initiative will not only enhance Axiom’s training protocols but will also involve seasoned astronauts such as Peggy Whitson and Koichi Wakata, who will train alongside Ventura throughout the program. López-Alegría confirmed that at least one of them will participate in each training event, underscoring Axiom’s commitment to ensuring safe, effective, and inspiring commercial space missions.

As the International Space Station approaches the end of its operational lifespan, the specifics of Ventura’s potential flight remain uncertain. There are discussions surrounding whether he will travel to the ISS or to a future Axiom Station once it becomes operational. Meanwhile, NASA is currently evaluating plans for its fifth and sixth private astronaut missions to the ISS. Axiom Space has secured contracts for the first four missions, with Axiom Mission 4 concluding in mid-July.

The establishment of Project Astronaut marks a significant step for Axiom Space in its efforts to refine astronaut training methods, setting a foundation for future commercial space endeavors. As Axiom prepares for its ambitious goals, Ventura’s leadership is expected to play a pivotal role in shaping the future of human spaceflight.
